I'm tring to connect "https://api.tdax.com/api/orders/?pair=btc_thb"
this url is working on chrome, postman.
I can connect this url with C#.
But ca'nt connect with java.
namespace Exchanges.Satang
{
class SatangApi
{
private static class WebApi
{
private static readonly HttpClient st_client = new HttpClient();
static WebApi()
{
st_client.Timeout = TimeSpan.FromSeconds(2);
}
public static HttpClient Client { get { return st_client; } }
public static string Query(string url)
{
var resultString = Client.GetStringAsync(url).Result;
return resultString;
}
}
public static string GetOrders(string symbol)
{
const string queryStr = "https://api.tdax.com/api/orders/?pair=";
var response = WebApi.Query(queryStr + symbol);
return response.ToString();
}
}
}
this C# code working well
but following java code not working, get 403 error.

Some servers expect a User-Agent header to be present in the request to consider it as a valid request. So you need to add that to your request as follows.
con.setRequestProperty("User-Agent", "My-User-Agent");
int responseCode = con.getResponseCode();
The value of this header (My-User-Agent in the above example) can be set to any String you desire for this endpoint. For example, Postman sets something like PostmanRuntime/7.16.3 for this.
C# might be doing this internally, so you didn't have to set it explicitly.
public String getOrders(SatangCurrencyPairs currencyPair) throws IOException, BadResponseException {
String operation="orders/?pair="+currencyPair.toString();
StringBuilder result = new StringBuilder();
URL url = new URL(baseUrl+operation);
//URL url_ = new URL("https://api.tdax.com/api/orders/?pair=btc_thb");
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setRequestProperty("User-Agent", "java client");
con.setRequestMethod("GET");
//https://api.tdax.com/api/orders/?pair=btc_thb
int responseCode=con.getResponseCode();
if(responseCode!=HttpURLConnection.HTTP_OK){
throw new BadResponseException(responseCode);
}
BufferedReader rd = new BufferedReader(new InputStreamReader(con.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
result.append(line);
}
rd.close();
return result.toString();
}
When I Debug my code get Response code 200 which means success. Then also I'm getting null response.

I have Tested My API in postman its Working with response code 200 and giving Response in json format but in my code its not working .
Hope you will understand my problem.
Thank you very much for your time and assistance in this matter.
The problem is probably from this line:
String query = builder.build().getEncodedQuery();
You need to use:
String query = builder.build().toString();
This is because getEncodedQuery() is only returning the query, from the documentation:
String getEncodedQuery ()
Gets the encoded query component from this URI. The query comes after the query separator ('?') and before the fragment separator ('#'). This method would return "q=android" for "http://www.google.com/search?q=android".
UPDATED
You're building the query after opening the connection, hence you having the error.
You need to build the url with the query first:
Uri uri = Uri.parse("http://ishook.com/users/friends/send_friend_request_json/")
.buildUpon()
.appendQueryParameter("sessionId", params[0])
.appendQueryParameter("UserId", params[1])
.appendQueryParameter("friendId", params[2]);
.build();
URL url = new URL(builtUri.toString());
conn = (HttpURLConnection)url.openConnection();
conn.setReadTimeout(READ_TIMEOUT);
conn.setConnectTimeout(CONNECTION_TIMEOUT);
conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
conn.connect();
Note: I haven't test the code. So, don't expected it working automagically.

Now I have retrive Leads from CRM using rest API I can not able to find the appropriate method and Url to do the thing.
I can see the list rest of API's from /help but I cant understand what should be my module name and what I have to :record and how do I pass my access token for authentication.
Can anyone please help me?
The module name is simply the module you which to fetch records from, so in your case you'll want to do a GET request to rest/v10/Leads for a list of Leads. If you want to fetch a specific Lead you replace :record with the id of a Lead - for example: GET rest/v10/Leads/LEAD-ID-HERE
SugarCRM's documentation has a lot of relevant information that might not be included in /help plus working examples.
http://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_7.8/Integration/Web_Services/v10/Endpoints/module_GET/
http://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_7.8/Integration/Web_Services/v10/Examples/PHP/How_to_Fetch_Related_Records/
You need to include your retrieved token into an OAuth-Token header for subsequent requests, and then just use the module name as the endpoint i.e. in your case: "rest/v10/Leads" and call the GET method to retrieve them. Try something akin to this:
String token = getAccessToken();
HttpURLConnection connection = null;
try {
URL url = new URL(HOST_URL + "/rest/v10/Leads");
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setRequestProperty("Content-Type", "application/json");
connection.setRequestProperty("OAuth-Token", token);
connection.setUseCaches(false);
connection.setDoOutput(true);
connection.connect();
int responseCode = connection.getResponseCode();
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
JSONObject jObject = new JSONObject(response.toString());
System.out.println(jObject);
} catch (Exception e) {
e.printStackTrace();
}
In the case you want to filter it down to specific id's to cut down on the amount of returned data, you can specify it after the module name i.e. "rest/v10/Leads/{Id}"
I'm currently trying to log in to a php server using HttpURLConnection. I have been successfully able to connect to the server/website as the response code I'm getting back is 200.
getPageContent has a response code of 200 while sendPost has a response code of 0. I am unsure about which getRequestProperty's are necessary and which aren't. I have looked at the elements and response and request headers and form data to get the correct information for the properties I did include however.
I can't really make too much sense of the string coming out of getPageContent as it is quite long but it does seem to be correct. getFormParams could possibly be outputting an incorrect string but information such as the username and password are included so I am unsure.
I'm stuck as to what's wrong or right in my attempt. Am I getting the form parameters correctly? And how do I send the login data correctly?
I call:
String page = getPageContent(URL);
String PostParams = getFormParams( page, "user", "pass" );
sendPost( URL, PostParams );
And the functions are:
private String getPageContent(String url) throws Exception {
URL obj = new URL( url );
HttpURLConnection conn = (HttpURLConnection) obj.openConnection();
// default is GET
conn.setRequestMethod("GET");
conn.setUseCaches(false);

conn.addRequestProperty("Cookie", cookie.split(";", 1)[0]);
}
}
int responseCode = conn.getResponseCode();
MainActivity.globalV.responsecode = responseCode;

while ((inputLine = in.readLine()) != null) {

in.close();
// Get the response cookies
setCookies(conn.getHeaderFields().get("Set-Cookie"));
MainActivity.globalV.getPageContent = responseCode;
return response.toString();
}

if (key.equals("user_username"))
value = username;
else if (key.equals("user_password"))
value = password;
paramList.add(key + "=" + URLEncoder.encode(value, "UTF-8"));
}
// build parameters list
StringBuilder result = new StringBuilder();
for (String param : paramList) {
if (result.length() == 0) {
result.append(param);
} else {
result.append("&" + param);
}
}
return result.toString();
}

I would like to generate POST request to a server which requires authentication. I tried to use the following method:
private synchronized String CreateNewProductPOST (String urlString, String encodedString, String title, String content, Double price, String tags) {
String data = "product[title]=" + URLEncoder.encode(title) +
"&product[content]=" + URLEncoder.encode(content) +
"&product[price]=" + URLEncoder.encode(price.toString()) +
"&tags=" + tags;
try {
URL url = new URL(urlString);
URLConnection conn;
conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encodedString);
conn.setDoOutput(true);
conn.setDoInput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();
// Get the response
BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
// Process line...
}
wr.close();
rd.close();
return rd.toString();
} catch (MalformedURLException e) {
e.printStackTrace();
return e.getMessage();
}
catch (IOException e) {
e.printStackTrace();
return e.getMessage();
}
}
but the server doesn't receive the authorization data. The line which is supposed to add authorization data is the following:
conn.setRequestProperty ("Authorization", "Basic " + encodedString);
and the line
BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
also throws an IOException.
Anyway I would be very thankful if anyone could suggest any fix of the logic above in order to enable authorization using POST with UrlConnection.
but obviously it doesn't work as it is supposed to although if the same logic is used for GET request everything works fine.
A fine example found here. Powerlord got it right, below, for POST you need HttpURLConnection, instead.
Below is the code to do that,
URL url = new URL(urlString);
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
conn.setRequestProperty ("Authorization", encodedCredentials);
OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());
writer.write(data);
writer.flush();
String line;
BufferedReader reader = new BufferedReader(new
InputStreamReader(conn.getInputStream()));
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
writer.close();
reader.close();
Change URLConnection to HttpURLConnection, to make it POST request.
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
Suggestion (...in comments):
You might need to set these properties too,
conn.setRequestProperty( "Content-type", "application/x-www-form-urlencoded");
conn.setRequestProperty( "Accept", "*/*" );
I don't see anywhere in the code where you specify that this is a POST request. Then again, you need a java.net.HttpURLConnection to do that.
In fact, I highly recommend using HttpURLConnection instead of URLConnection, with conn.setRequestMethod("POST"); and see if it still gives you problems.
To do oAuth authentication to external app (INSTAGRAM) Step 3 "get the token after receiving the code" Only code below worked for me
Worth to state also that it worked for me using some localhost URL with a callback servlet configured with name "callback in web.xml and callback URL registered: e.g. localhost:8084/MyAPP/docs/insta/callback
BUT after successfully completed authentication steps, using same external site "INSTAGRAM" to do GET of Tags or MEDIA to retrieve JSON data using initial method didn't work.
Inside my servlet to do GET using url like
e.g. api.instagram.com/v1/tags/MYTAG/media/recent?access_token=MY_TOKEN only method found HERE worked
Thanks to all contributors
URL url = new URL(httpurl);
HashMap<String, String> params = new HashMap<String, String>();
params.put("client_id", id);
params.put("client_secret", secret);
params.put("grant_type", "authorization_code");

params.put("code", code); // your INSTAGRAM code received
Set set = params.entrySet();

for (Map.Entry<String, String> param : params.entrySet()) {
if (postData.length() != 0) {
postData.append('&');
}
postData.append(URLEncoder.encode(param.getKey(), "UTF-8"));
postData.append('=');
postData.append(URLEncoder.encode(String.valueOf(param.getValue()), "UTF-8"));
}
byte[] postDataBytes = postData.toString().getBytes("UTF-8");
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
conn.setRequestProperty("Content-Length", String.valueOf(postDataBytes.length));
conn.setDoOutput(true);
conn.getOutputStream().write(postDataBytes);
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));
StringBuilder builder = new StringBuilder();
for (String line = null; (line = reader.readLine()) != null;) {
builder.append(line).append("\n");
}
reader.close();
conn.disconnect();
System.out.println("INSTAGRAM token returned: "+builder.toString());
To send a POST request call:
connection.setDoOutput(true); // Triggers POST.
If you want to sent text in the request use:
java.io.OutputStreamWriter wr = new java.io.OutputStreamWriter(connection.getOutputStream());
wr.write(textToSend);
wr.flush();
I ran into this problem today and none of the solutions posted here worked. However, the code posted here worked for a POST request:
// HTTP POST request
private void sendPost() throws Exception {
String url = "https://selfsolve.apple.com/wcResults.do";
URL obj = new URL(url);
HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();
//add reuqest header
con.setRequestMethod("POST");
con.setRequestProperty("User-Agent", USER_AGENT);
con.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
String urlParameters = "sn=C02G8416DRJM&cn=&locale=&caller=&num=12345";
// Send post request
con.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(con.getOutputStream());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
int responseCode = con.getResponseCode();
System.out.println("\nSending 'POST' request to URL : " + url);
System.out.println("Post parameters : " + urlParameters);
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
//print result
System.out.println(response.toString());
}
It turns out that it's not the authorization that's the problem. In my case, it was an encoding problem. The content-type I needed was application/json but from the Java documentation:
static String encode(String s, String enc)
Translates a string into application/x-www-form-urlencoded format using a specific encoding scheme.
The encode function translates the string into application/x-www-form-urlencoded.
Now if you don't set a Content-Type, you may get a 415 Unsupported Media Type error. If you set it to application/json or anything that's not application/x-www-form-urlencoded, you get an IOException. To solve this, simply avoid the encode method.
For this particular scenario, the following should work:
String data = "product[title]=" + title +
"&product[content]=" + content +
"&product[price]=" + price.toString() +
"&tags=" + tags;
Another small piece of information that might be helpful as to why the code breaks when creating the buffered reader is because the POST request actually only gets executed when conn.getInputStream() is called.
On API 22 The Use Of BasicNamevalue Pair is depricated, instead use the HASMAP for that. To know more about the HasMap visit here more on hasmap developer.android

and Just call the function when you needed to get the data from server either by post or get like this
HashMap<String, String>params = new HashMap<String, String>();
params.put("action", "request_sample");
params.put("name", uname);
params.put("message", umsg);
params.put("email", getEmailofUser());
params.put("type", "bio");
dq.doServerRequest(params, "your_url", DbConstants.METHOD_POST);
dq.setOnServerRequestCompleteListener(new ServerRequestHandler.OnServerRequestComplete() {
#Override
public void onSucess(Bundle bundle) {
debug("data", bundle.getString(DbConstants.RESPONSE));

#Override
public void onFailed(int status_code, String mesage, String url) {

}
});
Now it is complete.Enjoy!!! Comment it if find any problem.
HTTP authorization does not differ between GET and POST requests, so I would first assume that something else is wrong. Instead of setting the Authorization header directly, I would suggest using the java.net.Authorization class, but I am not sure if it solves your problem. Perhaps your server is somehow configured to require a different authorization scheme than "basic" for post requests?
i was looking information about how to do a POST request. I need to specify that mi request is a POST request because, i'm working with RESTful web services that only uses POST methods, and if the request isn't post, when i try to do the request i receive an HTTP error 405. I assure that my code isn't wrong doing the next: I create a method in my web service that is called through GET request and i point my application to consume that web service method and it works.
My code is the next:
URL server = null;
URLConnection conexion = null;
BufferedReader reader = null;
server = new URL("http://localhost:8089/myApp/resources/webService");
conexion = server.openConnection();
reader = new BufferedReader(new InputStreamReader(server.openStream()));
System.out.println(reader.readLine());
