OkHttp implement unit test?

OkHttp implement unit test? - java

I have a function using OkHttp to get data from third party api
public List<AuditData> getAuditData(OkHttpClient client, int retLabelId, int countryId, int periodId, int versionNo, String URL, String token) throws IOException {
DefaultGraphQLClient graphQLClient = new DefaultGraphQLClient(URL);
String query = QueryUtils.getAuditDataQuery(retLabelId, countryId, periodId, versionNo, PartitionUtil.getReadPartition(token));
GraphQLResponse response = graphQLClient.executeQuery(query, new HashMap<>(), "", (url, headers, body) -> {
Request request = new Request.Builder()
.header("Authorization", "Bearer " + token)
.url(url)
.post(RequestBody.create(okhttp3.MediaType.parse("text/x-markdown"), body))
.build();
try {
Response responseOkHttp = client.newCall(request).execute();
return new HttpResponse(responseOkHttp.code(), responseOkHttp.body().string());
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
);
return response.extractValueAsObject("data.auditData[*]", new TypeRef<List<AuditData>>() {
});
}
I want to write unit test for the function above. I have tried with MockWebServer and it doesn't work.
MockResponse response = new MockResponse()
.addHeader("Content-Type", "application/json; charset=utf-8")
.addHeader("Cache-Control", "no-cache")
.setBody(jsonResponse);
server.enqueue(response);
OkHttpClient client = new OkHttpClient();

Conditional Base pass dynamic value inside request body

I want to pass dynamic value inside request body in my case I pass
thirdpartypaymentGatewayToken in two place inside request body and an
other place requestString as requestBody but I want make single
function and pass values inside request body dynamic. for your
reference I post my old code and new code.
Here my old code
public ThirdPartyPaymentGatewayResponse getThirdPartyPaymentGatewayToken(ThirdPartyPaymentGatewayToken thirdPartyPaymentGatewayToken, String managedBy)
throws AuthenticationException, UnknownHostException, BadRequestException {
String brandwiseBearerToken = getBrandwiseAuthenticationToken();
ThirdPartyPaymentGatewayResponse thirdPartyPaymentGatewayResponse = new ThirdPartyPaymentGatewayResponse();
String thirdPartyPaymentGatewayTokenJson = ow.writeValueAsString(thirdPartyPaymentGatewayToken);
RequestBody body = RequestBody.create(mediaType, thirdPartyPaymentGatewayTokenJson);
Request request = new Request.Builder().url(brandwiseThirdPartypaymentGatewayURL)
.post(body)
.addHeader("Content-Type", "application/json")
.addHeader("Bearer", brandwiseBearerToken)
.build();
Response response = client.newCall(request).execute();
ResponseBody responseBody = response.body();
JsonObject jsonObject = new Gson().fromJson(responseBody.string(), JsonObject.class);
JsonElement error = jsonObject.get("Message");
}
> second function
public ThirdPartyPaymentGatewayResponse getThirdPartyPaymentGatewayToken(ThirdPartyPaymentGatewayToken thirdPartyPaymentGatewayToken, String managedBy)
throws AuthenticationException, UnknownHostException, BadRequestException {
String brandwiseBearerToken = getBrandwiseAuthenticationToken();
String thirdPartyPaymentGatewayTokenJson = ow.writeValueAsString(thirdPartyPaymentGatewayToken);
RequestBody body = RequestBody.create(mediaType, thirdPartyPaymentGatewayTokenJson);
Request request = new Request.Builder().url(brandwiseThirdPartypaymentGatewayURL)
.post(body)
.addHeader("Content-Type", "application/json")
.addHeader("Bearer", brandwiseBearerToken)
.build();
Response response = client.newCall(request).execute();
ResponseBody responseBody = response.body();
JsonObject jsonObject = new Gson().fromJson(responseBody.string(), JsonObject.class);
JsonElement error = jsonObject.get("Message");
/** rest of code*/
}
third function different than other two
private String getBrandwiseAuthenticationToken() throws UnknownHostException, AuthenticationException {
OkHttpClient client = new OkHttpClient();
MediaType mediaType = MediaType.parse("application/json");
String requestString = "{\"LoginName\": \"" + brandwiseAuthUsername + "\",\"Password\": \""+ brandwiseAuthPassword + "\"}";
RequestBody body = RequestBody.create(mediaType, requestString);
Request request = new Request.Builder().url(brandwiseAuthenticationURL)
.post(body)
.addHeader("Content-Type", "application/json")
.build();
Response response = client.newCall(request).execute();
ResponseBody responseBody = response.body();
JsonObject jsonObject = new Gson().fromJson(responseBody.string(), JsonObject.class);
}
To overcome from this issue I do this way but I am not able make
request body as dynamic. Here my new code
private JsonObject gateWayToken(String url,String brandwiseBearerToken,
ThirdPartyPaymentGatewayToken thirdPartyPaymentGatewayToken ) throws IOException, AuthenticationException{
ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
String requestString = "{\"LoginName\": \"" + brandwiseAuthUsername + "\",\"Password\": \""+ brandwiseAuthPassword + "\"}";
OkHttpClient client = new OkHttpClient();
MediaType mediaType = MediaType.parse("application/json");
RequestBody body=null;
//dynamic value accept by body
if(!Strings.isNullOrEmpty(requestString)) {
String brandwiseBearerPaymentGatewayTokenJson = ow.writeValueAsString(requestString);
body = RequestBody.create(mediaType,brandwiseBearerPaymentGatewayTokenJson);
}else {
String thirdPartyPaymentGatewayTokenJson = ow.writeValueAsString(thirdPartyPaymentGatewayToken);
body = RequestBody.create(mediaType,thirdPartyPaymentGatewayTokenJson );
}
//if user is authenticated then header part will show
Request request=null;
if (brandwiseBearerToken != null && StringUtils.isNotEmpty(brandwiseBearerToken)) {
request =new Request.Builder().url(url).post(body)
.addHeader("Content-Type", "application/json")
.addHeader("Bearer", brandwiseBearerToken)
.build();
} else {
request=new Request.Builder().url(url).post(body)
.addHeader("Content-Type", "application/json")
.build();
}
Response response = client.newCall(request).execute();
ResponseBody responseBody = response.body();
return new Gson().fromJson(responseBody.string(), JsonObject.class);
}
I want to dynamic exact at this point
if(!Strings.isNullOrEmpty(requestString)) {
String brandwiseBearerPaymentGatewayTokenJson = ow.writeValueAsString(requestString);
body = RequestBody.create(mediaType,brandwiseBearerPaymentGatewayTokenJson);
}else {
String thirdPartyPaymentGatewayTokenJson = ow.writeValueAsString(thirdPartyPaymentGatewayToken);
body = RequestBody.create(mediaType,thirdPartyPaymentGatewayTokenJson );
}
Check Passing values inside ReqestBody

Java REST endpoint returning response 200 but the body is blank

I have a REST Service (Java 7) which I call via a REST Client (Java 11).
Maven Dependency
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>4.9.1</version>
</dependency>
REST Service
#GET
#Path("trip/{tripId}")
#ApiOperation(value="Returns the details for a trip.")
#ApiResponses({
#ApiResponse(code=200, message="Success"),
#ApiResponse(code=404, message="Not Found")
})
#Produces({ MediaType.APPLICATION_JSON })
public Response getTripDetails(#HeaderParam("Authorization") String token, #Context HttpServletRequest request, #PathParam("tripId") final String tripId) {
super.init(jwtTokenUtil, memberService, travelAgencyFacade);
TripDetailsResponse tripDetailsResponse = new TripDetailsResponse();
try {
tripDetailsResponse.setTripId(tripId);
final Long tripIdL = Long.valueOf(tripId);
TripDTO tripDTO = trips.getTripDetails(tripIdL);
tripDetailsResponse.setTripDTO(null);
tripDetailsResponse.setStatus(ResourceConstants.SUCCESS_STATUS);
Response response = Response.ok().entity(tripDetailsResponse).build();
return response;
} catch (Exception e) {
return handleError(e, logger, tripDetailsResponse, true);
}
}
I test the REST Service in Postman, and it returns the following JSON as expected:
{
"tripId": "1801855",
"tripDTO": null,
"messages": [],
"status": "success"
}
REST Client
private Response callGETEndpoint(final String url) throws IOException, NoSuchAlgorithmException, KeyManagementException {
TrustManager[] trustAllCerts = getTrustManager();
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
OkHttpClient okHttpClient = new OkHttpClient();
Request request = new Request.Builder()
.url(url)
.get()
.build();
okHttpClient.setSslSocketFactory(sc.getSocketFactory());
okHttpClient.setHostnameVerifier(new HostnameVerifier() {
#Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
logger.info(url);
try {
Response response = okHttpClient.newCall(request).execute();
return response;
} catch (SocketTimeoutException e) {
// try again
try {
Response response = okHttpClient.newCall(request).execute();
return response;
} catch (SocketTimeoutException ex) {
logger.error("Call to "+url+" timed out.", ex);
}
}
return null;
}
Call of the Client
Response response = client.callGETEndpoint(url);
if (response != null && response.isSuccessful()) {
if (response.code() == 200) {
final ResponseBody responseBody = response.body();
final String responseString = responseBody.string();
Problem
The response does have a status of 200. However, the responseString is blank. I would expect it to contain the data seen in the Postman response.
Question
What do I need to do to get the body from the response?

You can try this for parsing
import com.jayway.jsonpath.JsonPath;
....
ReadContext rContext = JsonPath.parse(response.body().string())

How do I transfer data from an asynchronous request to a class variable? OkHttp3, Java

I'm using an asynchronous request (because synchronous doesn't work correctly with this API), the OkHttp3 library. Inside the request, I get a response in the form of JSON. I need to somehow pass values from Json to a class variable. I decided to try it this way, but it doesn't work.
public String sessionId = null;
...
public QRcodeReader() throws Exception {
this.sessionId = null;
}
... // between this code I have 1 function, which reg my number.
// in this func I need to confirm my phone by code in SMS.
public void SmsCode(String Code) // String get from another class
{
SmsJson smsJson = new SmsJson("*phoneNumber*", "*secret_key*", "*os*", Code);
Gson gson = new GsonBuilder().disableHtmlEscaping().create();
RequestBody body = RequestBody.create(
MediaType.parse("application/json"), gson.toJson(smsJson));
Request request = new Request.Builder()
.url("https://irkkt-mobile.nalog.ru:8888/v2/auth/phone/verify")
.addHeader("Host", HOST)
.addHeader("Accept", ACCEPT)
.addHeader("Device-OS", DEVICE_OS)
.addHeader("Device-ID", DEVICE_ID)
.addHeader("clientVersion", CLIENT_VERSION)
.addHeader("Accept-Language", ACCEPT_LANGUAGE)
.addHeader("User-Agent", USER_AGENT)
.post(body)
.build();
httpClient.newCall(request).enqueue(new Callback() {
#Override
public void onResponse(#NonNull Call call, #NonNull Response response) throws IOException {
try (Response responseBody = httpClient.newCall(request).execute()) {
if (!responseBody.isSuccessful())
throw new IOException("Unexpected code " + responseBody);
// Here I try to transfer data from request to class variable. Not Work.
SetSessionId(Objects.requireNonNull(responseBody.body()).string());
System.out.println(Objects.requireNonNull(responseBody.body()).string());
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void onFailure(Call call, IOException e) {
e.printStackTrace();
}
});
}
void SetSessionId(String sessionId){
this.sessionId = sessionId;
}
I need to use SessionID further along here:
public String GetTicketID(String QR){
TicketID ticketID = new TicketID(QR);
Gson gson = new GsonBuilder().disableHtmlEscaping().create();
RequestBody body = RequestBody.create(
MediaType.parse("application/json"), gson.toJson(ticketID));
Request request = new Request.Builder()
.url("https://irkkt-mobile.nalog.ru:8888/v2/ticket")
.addHeader("Host", HOST)
.addHeader("Accept", ACCEPT)
.addHeader("Device-OS", DEVICE_OS)
.addHeader("Device-ID", DEVICE_ID)
.addHeader("clientVersion", CLIENT_VERSION)
.addHeader("Accept-Language", ACCEPT_LANGUAGE)
.addHeader("User-Agent", USER_AGENT)
.addHeader("sessionId", sessionId) // Here I get NULL and exception!
.post(body)
.build();
httpClient.newCall(request).enqueue(new Callback() {
#Override
public void onResponse(Call call, Response response) throws IOException {
try (Response responseBody = httpClient.newCall(request).execute()) {
if (!responseBody.isSuccessful())
throw new IOException("Unexpected code " + responseBody);
System.out.println(Objects.requireNonNull(responseBody.body()).string());
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void onFailure(Call call, IOException e) {
e.printStackTrace();
}
});
return ""; // Here I need to transfer id to another variable, not did it yet.
}
The problem is that SessionID = Null and the request does not work.
I think I'm doing something wrong, but I can't figure out what. May be it is because async request..

Okhttp Interceptor issue

I'm trying to add a header to a simple okhttp (Get) request. How do I add the HttpHeader properly? Can I debug to ensure that my Header is actually sent to the server?
Request request = new Request.Builder()
.url("URL")
.build();
OkHttpClient okHttpClient = new OkHttpClient.Builder()
.addInterceptor(new Interceptor() {
#Override
public okhttp3.Response intercept(Chain chain) throws IOException {
Request originalRequest = chain.request();
Request newRequest = originalRequest.newBuilder()
.addHeader("Header", "123")
.build();
return chain.proceed(newRequest);
}
})
.build();
okHttpClient.newCall(request).enqueue(new Callback() {
#Override
public void onFailure(Call call, IOException e) {
}
I've looked for basic simple examples but they are with Retrofit, GSON, Interfaces, or in Kotlin. Need to understand it codewise.

You can use by method addHeader send chain as param and add headers.
Request getRequest = chain.request();
Request.Builder requestBuilder = getRequest.newBuilder()
.addHeader("Header", "123");
Request request = requestBuilder.build();
return chain.proceed(request);
You can also visit and look at the answers link1 and link2.
Here is the all-request Structure you can use.
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(new Interceptor() {
#Override
public Response intercept(Interceptor.Chain chain) throws IOException {
Request original = chain.request();
Request request = original.newBuilder()
.method(original.method(), original.body())
.build();
return chain.proceed(request);
}
};
OkHttpClient client = httpClient.build();
Request request = new Request.Builder()
.url("URL")
.addHeader("Header", "123")
.build();
client.newCall(request).enqueue(new Callback() {
#Override
public void onFailure(Call call, IOException e) {
e.printStackTrace();
Log.d("OKHTTP3", e.getMessage());
// You get this failure
runOnUiThread(() -> {
});
}
#Override
public void onResponse(Call call, Response response) throws IOException {
try {
final String _body = response.body().string();
Log.d("OKHTTP3", _body);
runOnUiThread(() -> {
});
} catch (InterruptedIOException e) {
runOnUiThread(() -> {
// Or this exception depending when timeout is reached
});
}
}
});

To check your request and to add headers, you can use interceptors.
To add headers, (copied from gist):
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(new Interceptor() {
#Override
public Response intercept(Interceptor.Chain chain) throws IOException {
Request original = chain.request();
Request request = original.newBuilder()
.header("User-Agent", "Your-App-Name")
.header("Accept", "application/vnd.yourapi.v1.full+json")
.method(original.method(), original.body())
.build();
return chain.proceed(request);
}
}
OkHttpClient client = httpClient.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(API_BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();
To see your headers, you can use sample example provided here:
class LoggingInterceptor implements Interceptor {
#Override public Response intercept(Interceptor.Chain chain) throws IOException {
Request request = chain.request();
long t1 = System.nanoTime();
logger.info(String.format("Sending request %s on %s%n%s",
request.url(), chain.connection(), request.headers()));
Response response = chain.proceed(request);
long t2 = System.nanoTime();
logger.info(String.format("Received response for %s in %.1fms%n%s",
response.request().url(), (t2 - t1) / 1e6d, response.headers()));
return response;
}
}

Use addHeader() to add headers. header() sets the already added header name to the value.
Request newRequest = originalRequest.newBuilder()
.addHeader("Header", "123")
.build();
And to verify it's working correctly, you can use HttpLoggingInterceptor to log your network requests.

How to use OKHTTP to make a post request?

I read some examples which are posting jsons to the server.
some one says :
OkHttp is an implementation of the HttpUrlConnection interface
provided by Java. It provides an input stream for writing content and
doesn't know (or care) about what format that content is.
Now I want to make a normal post to the URL with params of name and password.
It means I need to do encode the name and value pair into stream by myself?

As per the docs, OkHttp version 3 replaced FormEncodingBuilder with FormBody and FormBody.Builder(), so the old examples won't work anymore.
Form and Multipart bodies are now modeled. We've replaced the opaque
FormEncodingBuilder with the more powerful FormBody and
FormBody.Builder combo.
Similarly we've upgraded MultipartBuilder into
MultipartBody, MultipartBody.Part, and MultipartBody.Builder.
So if you're using OkHttp 3.x try the following example:
OkHttpClient client = new OkHttpClient();
RequestBody formBody = new FormBody.Builder()
.add("message", "Your message")
.build();
Request request = new Request.Builder()
.url("https://www.example.com/index.php")
.post(formBody)
.build();
try {
Response response = client.newCall(request).execute();
// Do something with the response.
} catch (IOException e) {
e.printStackTrace();
}

The current accepted answer is out of date. Now if you want to create a post request and add parameters to it you should user MultipartBody.Builder as Mime Craft now is deprecated.
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("somParam", "someValue")
.build();
Request request = new Request.Builder()
.url(BASE_URL + route)
.post(requestBody)
.build();

private final OkHttpClient client = new OkHttpClient();
public void run() throws Exception {
RequestBody formBody = new FormEncodingBuilder()
.add("search", "Jurassic Park")
.build();
Request request = new Request.Builder()
.url("https://en.wikipedia.org/w/index.php")
.post(formBody)
.build();
Response response = client.newCall(request).execute();
if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
System.out.println(response.body().string());
}

You need to encode it yourself by escaping strings with URLEncoder and joining them with "=" and "&". Or you can use FormEncoder from Mimecraft which gives you a handy builder.
FormEncoding fe = new FormEncoding.Builder()
.add("name", "Lorem Ipsum")
.add("occupation", "Filler Text")
.build();

You can make it like this:
MediaType JSON = MediaType.parse("application/json; charset=utf-8");
RequestBody body = RequestBody.create(JSON, "{"jsonExample":"value"}");
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url(url)
.post(body)
.addHeader("Authorization", "header value") //Notice this request has header if you don't need to send a header just erase this part
.build();
Call call = client.newCall(request);
call.enqueue(new Callback() {
#Override
public void onFailure(Request request, IOException e) {
Log.e("HttpService", "onFailure() Request was: " + request);
e.printStackTrace();
}
#Override
public void onResponse(Response r) throws IOException {
response = r.body().string();
Log.e("response ", "onResponse(): " + response );
}
});

OkHttp POST request with token in header
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("search", "a")
.addFormDataPart("model", "1")
.addFormDataPart("in", "1")
.addFormDataPart("id", "1")
.build();
OkHttpClient client = new OkHttpClient();
okhttp3.Request request = new okhttp3.Request.Builder()
.url("https://somedomain.com/api")
.post(requestBody)
.addHeader("token", "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiIkMnkkMTAkZzZrLkwySlFCZlBmN1RTb3g3bmNpTzltcVwvemRVN2JtVC42SXN0SFZtbzZHNlFNSkZRWWRlIiwic3ViIjo0NSwiaWF0IjoxNTUwODk4NDc0LCJleHAiOjE1NTM0OTA0NzR9.tefIaPzefLftE7q0yKI8O87XXATwowEUk_XkAOOQzfw")
.addHeader("cache-control", "no-cache")
.addHeader("Postman-Token", "7e231ef9-5236-40d1-a28f-e5986f936877")
.build();
client.newCall(request).enqueue(new Callback() {
#Override
public void onFailure(Call call, IOException e) {
e.printStackTrace();
}
#Override
public void onResponse(Call call, okhttp3.Response response) throws IOException {
if (response.isSuccessful()) {
final String myResponse = response.body().string();
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
Log.d("response", myResponse);
progress.hide();
}
});
}
}
});

To add okhttp as a dependency do as follows
right click on the app on android studio open "module settings"
"dependencies"-> "add library dependency" -> "com.squareup.okhttp3:okhttp:3.10.0" -> add -> ok..
now you have okhttp as a dependency
Now design a interface as below so we can have the callback to our activity once the network response received.
public interface NetworkCallback {
public void getResponse(String res);
}
I create a class named NetworkTask so i can use this class to handle all the network requests
public class NetworkTask extends AsyncTask<String , String, String>{
public NetworkCallback instance;
public String url ;
public String json;
public int task ;
OkHttpClient client = new OkHttpClient();
public static final MediaType JSON
= MediaType.parse("application/json; charset=utf-8");
public NetworkTask(){
}
public NetworkTask(NetworkCallback ins, String url, String json, int task){
this.instance = ins;
this.url = url;
this.json = json;
this.task = task;
}
public String doGetRequest() throws IOException {
Request request = new Request.Builder()
.url(url)
.build();
Response response = client.newCall(request).execute();
return response.body().string();
}
public String doPostRequest() throws IOException {
RequestBody body = RequestBody.create(JSON, json);
Request request = new Request.Builder()
.url(url)
.post(body)
.build();
Response response = client.newCall(request).execute();
return response.body().string();
}
#Override
protected String doInBackground(String[] params) {
try {
String response = "";
switch(task){
case 1 :
response = doGetRequest();
break;
case 2:
response = doPostRequest();
break;
}
return response;
}catch (Exception e){
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
instance.getResponse(s);
}
}
now let me show how to get the callback to an activity
public class MainActivity extends AppCompatActivity implements NetworkCallback{
String postUrl = "http://your-post-url-goes-here";
String getUrl = "http://your-get-url-goes-here";
Button doGetRq;
Button doPostRq;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = findViewById(R.id.button);
doGetRq = findViewById(R.id.button2);
doPostRq = findViewById(R.id.button1);
doPostRq.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
MainActivity.this.sendPostRq();
}
});
doGetRq.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
MainActivity.this.sendGetRq();
}
});
}
public void sendPostRq(){
JSONObject jo = new JSONObject();
try {
jo.put("email", "yourmail");
jo.put("password","password");
} catch (JSONException e) {
e.printStackTrace();
}
// 2 because post rq is for the case 2
NetworkTask t = new NetworkTask(this, postUrl, jo.toString(), 2);
t.execute(postUrl);
}
public void sendGetRq(){
// 1 because get rq is for the case 1
NetworkTask t = new NetworkTask(this, getUrl, jo.toString(), 1);
t.execute(getUrl);
}
#Override
public void getResponse(String res) {
// here is the response from NetworkTask class
System.out.println(res)
}
}

This is one of the possible solutions to implementing an OKHTTP post request without a request body.
RequestBody reqbody = RequestBody.create(null, new byte[0]);
Request.Builder formBody = new Request.Builder().url(url).method("POST",reqbody).header("Content-Length", "0");
clientOk.newCall(formBody.build()).enqueue(OkHttpCallBack());

You should check tutorials on lynda.com. Here is an example of how to encode the parameters, make HTTP request and then parse response to json object.
public JSONObject getJSONFromUrl(String str_url, List<NameValuePair> params) {
String reply_str = null;
BufferedReader reader = null;
try {
URL url = new URL(str_url);
OkHttpClient client = new OkHttpClient();
HttpURLConnection con = client.open(url);
con.setDoOutput(true);
OutputStreamWriter writer = new OutputStreamWriter(con.getOutputStream());
writer.write(getEncodedParams(params));
writer.flush();
StringBuilder sb = new StringBuilder();
reader = new BufferedReader(new InputStreamReader(con.getInputStream()));
String line;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
reply_str = sb.toString();
} catch (Exception e) {
e.printStackTrace();
return null;
} finally {
if (reader != null) {
try {
reader.close();
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
}
// try parse the string to a JSON object. There are better ways to parse data.
try {
jObj = new JSONObject(reply_str);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
return jObj;
}
//in this case it's NameValuePair, but you can use any container
public String getEncodedParams(List<NameValuePair> params) {
StringBuilder sb = new StringBuilder();
for (NameValuePair nvp : params) {
String key = nvp.getName();
String param_value = nvp.getValue();
String value = null;
try {
value = URLEncoder.encode(param_value, "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
if (sb.length() > 0) {
sb.append("&");
}
sb.append(key + "=" + value);
}
return sb.toString();
}

// Do something with the response.
} catch (IOException e) {

}
return null;
}

Here is my method to do post request
first pass in method map and data like
HashMap<String, String> param = new HashMap<String, String>();
param.put("Name", name);
param.put("Email", email);
param.put("Password", password);
param.put("Img_Name", "");
final JSONObject result = doPostRequest(map,Url);
public static JSONObject doPostRequest(HashMap<String, String> data, String url) {
try {
RequestBody requestBody;
MultipartBuilder mBuilder = new MultipartBuilder().type(MultipartBuilder.FORM);
if (data != null) {
for (String key : data.keySet()) {
String value = data.get(key);
Utility.printLog("Key Values", key + "-----------------" + value);
mBuilder.addFormDataPart(key, value);
}
} else {
mBuilder.addFormDataPart("temp", "temp");
}
requestBody = mBuilder.build();
Request request = new Request.Builder()
.url(url)
.post(requestBody)
.build();
OkHttpClient client = new OkHttpClient();
Response response = client.newCall(request).execute();
String responseBody = response.body().string();
Utility.printLog("URL", url);
Utility.printLog("Response", responseBody);
return new JSONObject(responseBody);
} catch (UnknownHostException | UnsupportedEncodingException e) {
JSONObject jsonObject=new JSONObject();
try {
jsonObject.put("status","false");
jsonObject.put("message",e.getLocalizedMessage());
} catch (JSONException e1) {
e1.printStackTrace();
}
Log.e(TAG, "Error: " + e.getLocalizedMessage());
} catch (Exception e) {
e.printStackTrace();
JSONObject jsonObject=new JSONObject();
try {
jsonObject.put("status","false");
jsonObject.put("message",e.getLocalizedMessage());
} catch (JSONException e1) {
e1.printStackTrace();
}
Log.e(TAG, "Other Error: " + e.getLocalizedMessage());
}
return null;
}

Add the following to the build.gradle
compile 'com.squareup.okhttp3:okhttp:3.7.0'
Create a new thread, in the new thread add the following code.
OkHttpClient client = new OkHttpClient();
MediaType MIMEType= MediaType.parse("application/json; charset=utf-8");
RequestBody requestBody = RequestBody.create (MIMEType,"{}");
Request request = new Request.Builder().url(url).post(requestBody).build();
Response response = client.newCall(request).execute();

As for Kotlin in 2022 (POST request) works:
val client = OkHttpClient()
val formBody: RequestBody = MultipartBody.Builder()
.addFormDataPart("phone", editText1.text.toString())
.addFormDataPart("email", editText2.text.toString())
.build()
val request: Request = Request.Builder()
.url("https://hellokitty.com/users")
.post(formBody)
.build()
try {
// Do something with the response.
val response = client.newCall(request).enqueue(object : Callback {
override fun onFailure(call: Call, e: okio.IOException) {
print(e.message)
}
override fun onResponse(call: Call, response: Response) {
print(response.message)
print("XXX \n" + response.body)
}
})
editTextResponse.text = response.toString()
} catch (e: java.io.IOException) {
editTextResponse.text = e.toString()
e.printStackTrace()
}
Gradle:
implementation("com.squareup.okhttp3:okhttp:5.0.0-alpha.6")
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.jaskierltd.blablaApp">
<uses-permission android:name="android.permission.INTERNET"/>
...

If you want to post parameter in okhttp as body content which can be encrypted string with content-type as "application/x-www-form-urlencoded" you can first use URLEncoder to encode the data and then use :
final MediaType MEDIA_TYPE_MARKDOWN = MediaType.parse("application/x-www-form-urlencoded");
okhttp3.Request request = new okhttp3.Request.Builder()
.url(urlOfServer)
.post(RequestBody.create(MEDIA_TYPE_MARKDOWN, yourBodyDataToPostOnserver))
.build();
you can add header according to your requirement.

public static JSONObject doPostRequestWithSingleFile(String url,HashMap<String, String> data, File file,String fileParam) {
try {
final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png");
RequestBody requestBody;
MultipartBuilder mBuilder = new MultipartBuilder().type(MultipartBuilder.FORM);
for (String key : data.keySet()) {
String value = data.get(key);
Utility.printLog("Key Values", key + "-----------------" + value);
mBuilder.addFormDataPart(key, value);
}
if(file!=null) {
Log.e("File Name", file.getName() + "===========");
if (file.exists()) {
mBuilder.addFormDataPart(fileParam, file.getName(), RequestBody.create(MEDIA_TYPE_PNG, file));
}
}
requestBody = mBuilder.build();
Request request = new Request.Builder()
.url(url)
.post(requestBody)
.build();
OkHttpClient client = new OkHttpClient();
Response response = client.newCall(request).execute();
String result=response.body().string();
Utility.printLog("Response",result+"");
return new JSONObject(result);
} catch (UnknownHostException | UnsupportedEncodingException e) {
Log.e(TAG, "Error: " + e.getLocalizedMessage());
JSONObject jsonObject=new JSONObject();
try {
jsonObject.put("status","false");
jsonObject.put("message",e.getLocalizedMessage());
} catch (JSONException e1) {
e1.printStackTrace();
}
} catch (Exception e) {
Log.e(TAG, "Other Error: " + e.getMessage());
JSONObject jsonObject=new JSONObject();
try {
jsonObject.put("status","false");
jsonObject.put("message",e.getLocalizedMessage());
} catch (JSONException e1) {
e1.printStackTrace();
}
}
return null;
}
public static JSONObject doGetRequest(HashMap<String, String> param,String url) {
JSONObject result = null;
String response;
Set keys = param.keySet();
int count = 0;
for (Iterator i = keys.iterator(); i.hasNext(); ) {
count++;
String key = (String) i.next();
String value = (String) param.get(key);
if (count == param.size()) {
Log.e("Key",key+"");
Log.e("Value",value+"");
url += key + "=" + URLEncoder.encode(value);
} else {
Log.e("Key",key+"");
Log.e("Value",value+"");
url += key + "=" + URLEncoder.encode(value) + "&";
}
}
/*
try {

} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}*/
Log.e("URL", url);

.url(url)
.build();
Response responseClient = null;
try {
