I'm trying to make a POST request from my android app to a .php file but it doesn't work. It should send the scannedData value to my .php script but instead it returns "false: 500".
Does anybody know why? Since they changed that you can't use httppost anymore most of the answers on StackOverflow are outdated.
public class SendRequest extends AsyncTask<String, Void, String> {
protected void onPreExecute(){}
protected String doInBackground(String... arg0) {
try{
//Enter script URL Here
URL url = new URL("https://example.com/code.php");
JSONObject postDataParams = new JSONObject();
//int i;
//for(i=1;i<=70;i++)
// String usn = Integer.toString(i);
//Passing scanned code as parameter
postDataParams.put("sdata",scannedData);
Log.e("params",postDataParams.toString());
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(15000 /* milliseconds */);
conn.setConnectTimeout(15000 /* milliseconds */);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(getPostDataString(postDataParams));
writer.flush();
writer.close();
os.close();
int responseCode=conn.getResponseCode();
if (responseCode == HttpsURLConnection.HTTP_OK) {
BufferedReader in=new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuffer sb = new StringBuffer("");
String line="";
while((line = in.readLine()) != null) {
sb.append(line);
break;
}
in.close();
return sb.toString();
}
else {
return new String("false : "+responseCode);
}
}
catch(Exception e){
return new String("Exception: " + e.getMessage());
}
}
#Override
protected void onPostExecute(String result) {
Toast.makeText(getApplicationContext(), result,
Toast.LENGTH_LONG).show();
}
}
public String getPostDataString(JSONObject params) throws Exception {
StringBuilder result = new StringBuilder();
boolean first = true;
Iterator<String> itr = params.keys();
while(itr.hasNext()){
String key= itr.next();
Object value = params.get(key);
if (first)
first = false;
else
result.append("&");
result.append(URLEncoder.encode(key, "UTF-8"));
result.append("=");
result.append(URLEncoder.encode(value.toString(), "UTF-8"));
}
return result.toString();
}
When I Debug my code get Response code 200 which means success. Then also I'm getting null response.
Following is my AsyncTask Class:
private class AsyncAddfriend extends AsyncTask<String, String, String> {
HttpURLConnection conn;
URL url = null;
#Override
protected String doInBackground(String... params) {
try {
url = new URL("http://ishook.com/users/friends/send_friend_request_json/");
} catch (MalformedURLException e) {
e.printStackTrace();
}
try {
conn = (HttpURLConnection)url.openConnection();
conn.setReadTimeout(READ_TIMEOUT);
conn.setConnectTimeout(CONNECTION_TIMEOUT);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
Uri.Builder builder = new Uri.Builder()
.appendQueryParameter("sessionId", params[0])
.appendQueryParameter("UserId", params[1])
.appendQueryParameter("friendId", params[2]);
String query = builder.build().getEncodedQuery();
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(query);
writer.flush();
writer.close();
os.close();
conn.connect();
} catch (IOException e) {
e.printStackTrace();
}
try {
int response_code = conn.getResponseCode();
// Check if successful connection made
if (response_code == HttpURLConnection.HTTP_OK) {
// Read data sent from server
InputStream input = conn.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
StringBuilder result = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
result.append(line);
}
// Pass data to onPostExecute method
return(result.toString());
}else{
return("unsuccessful");
}
} catch (IOException e) {
e.printStackTrace();
return "exception";
} finally {
conn.disconnect();
}
}}
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.
I'm a novice creating a basic login app for Android, using 000webhost as my server.
My Java code:
ArrayList<NameValuePair> dataToSend = new ArrayList<>();
dataToSend.add(new BasicNameValuePair("name", user.name));
dataToSend.add(new BasicNameValuePair("email", user.email));
dataToSend.add(new BasicNameValuePair("password", user.password));
dataToSend.add(new BasicNameValuePair("leagueID", user.leagueID + ""));
HttpParams httpRequestParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpRequestParams, CONNECTION_TIMEOUT);
HttpConnectionParams.setSoTimeout(httpRequestParams, CONNECTION_TIMEOUT);
HttpClient client = new DefaultHttpClient(httpRequestParams);
HttpPost post = new HttpPost("http://subdomain.site88.net/register.php");
try{
post.setEntity(new UrlEncodedFormEntity(dataToSend));
client.execute(post);
}catch(Exception e){
e.printStackTrace();
}
return null;
My PHP code
<?php
$con = mysqli_connect("mysql1.000webhost.com", "username", "password", "dbname");
/***I want to get this data from Java side of application***/
$name = $_POST["name"];
$email = $_POST["email"];
$password = $_POST["password"];
$leagueID = $_POST["LeagueID"];
/***this works
$name = "John Doe";
$email = "JohnDoe#gmail.com";
$password = "password"
$leagueID = 0;
***/
echo "Hello";//place this here to check website to see if its showing up
//Now we will add the name, email, password, and leagueID into a table called "user".
$statement = mysqli_prepare($con, "INSERT INTO user (email, name, password, leagueID) VALUES (?, ?, ?, ?)");
mysqli_stmt_bind_param($statement, "sssi", $email, $name, $password, $leagueID);
mysqli_stmt_execute($statement);
mysqli_stmt_close($statement);
//finish up by closing the connection
mysqli_close($con);
?>
If I hardwire the values into the PHP code instead of using the $_POST method, it is sent to the database as requested. However, it seems that the $_POST variable is empty. I'm not quite sure why this is the case. Is it perhaps that 000webhost has some sort of setting that doesn't allow for someone to post data?
Also, I'm aware that I'm using deprecated java methods and how insecure my password storage currently is. I'll modify that in the future, but I'd first like to know how to post data.
Thanks in advance!
HttpClient is now deprecated, so you should use HttpUrlConnection instead, to send post request to server.
Create a new Class which will send a asynchronous post request to your server.
public class YourAyncClass extends AsyncTask<String, Void, String>{
public YourAyncClass(Context c){
this.context = c;
}
public SaveCampaign(){}
protected void onPreExecute(){}
#Override
protected String doInBackground(String... arg0) {
try{
URL url = new URL("Your url here");
JSONObject urlParameters = new JSONObject();
urlParameters.put("name", "John Doe");
urlParameters.put("email", "john#doe.com");
urlParameters.put("password", "xxxxxx");
urlParameters.put("leagueId", "123-456");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setConnectTimeout(15000);
connection.setReadTimeout(15000);
OutputStream os = connection.getOutputStream();
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
writer.write(getPostDataString(urlParameters));
writer.flush();
writer.close();
os.close();
int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuffer sb = new StringBuffer("");
String line = "";
while ((line = in.readLine()) != null) {
sb.append(line);
break;
}
in.close();
return sb.toString();
}
else {
return new String("New Exception : "+responseCode);
}
}
catch(Exception e){
return new String("Exception: " + e.getMessage());
}
}
protected void onPostExecute(String result){
}
/*This method changes the json object into url encoded key-value pair*/
public String getPostDataString(JSONObject params) throws Exception {
StringBuilder result = new StringBuilder();
boolean first = true;
Iterator<String> itr = params.keys();
while(itr.hasNext()){
String key= itr.next();
Object value = params.get(key);
if (first)
first = false;
else
result.append("&");
result.append(URLEncoder.encode(key, "UTF-8"));
result.append("=");
result.append(URLEncoder.encode(value.toString(), "UTF-8"));
}
return result.toString();
}
}
Now, to use this class in your method you need to implement following code in your code :
new YourAsyncClass(context).execute();
The above line of code calls the execute() method of AsyncTask class and starts the execution of your http call to server.
I want to execute an insertion query with some parameters in my android app.
For example in php it is something like:-
$query ="insert into inventoryproductrel(id, productid, sequence_no, quantity, listprice) values(?,?,?,?,?)";
$qparams = array($id,$prod['prod'],$counter,$prod['pcs'],$prod['price']);
$productadded=$adb->pquery($query,$qparams);
Here pquery is a function:-
function pquery($sql, $params){
global $log, $default_charset;
$log->debug('Prepared sql query being executed : '.$sql);
$this->checkConnection();
$this->executeSetNamesUTF8SQL();
$sql_start_time = microtime(true);
$params = $this->flatten_array($params);
if (count($params) > 0) {
$log->debug('Prepared sql query parameters : [' . implode(",", $params) . ']');
}
if($this->avoidPreparedSql || empty($params)) {
$sql = $this->convert2Sql($sql, $params);
$result = &$this->database->Execute($sql);
} else {
$result = &$this->database->Execute($sql, $params);
}
$sql_end_time = microtime(true);
$this->logSqlTiming($sql_start_time, $sql_end_time, $sql, $params);
$this->lastmysqlrow = -1;
return $result;
}
I don't know how to do this i.e. executing a query with parameters in java/android.
You can make a POST Request from your Android Application to the same PHP Script and just before inserting the the value to the database, set the values of the variales from the POST Parameters.
Use the following code to make POST Requests. Make sure you do this from an AsyncTask or a separate thread :
public String makePOSTRequestNew(String urlString,
List<NameValuePair> nameValuePairs) {
URL url;
String response = "";
try {
url = new URL(urlString);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(
os, "UTF-8"));
writer.write(getQuery(nameValuePairs));
writer.flush();
writer.close();
os.close();
InputStream responseStream = new BufferedInputStream(
conn.getInputStream());
BufferedReader responseStreamReader = new BufferedReader(
new InputStreamReader(responseStream));
String line = "";
StringBuilder stringBuilder = new StringBuilder();
while ((line = responseStreamReader.readLine()) != null) {
stringBuilder.append(line);
}
responseStreamReader.close();
response = stringBuilder.toString();
conn.connect();
} catch (IOException e) {
e.printStackTrace();
}
return response;
}
The getQuery() Method creates a parameter String from the nameValuePairs :
private String getQuery(List<NameValuePair> params)
throws UnsupportedEncodingException {
StringBuilder result = new StringBuilder();
boolean first = true;
for (NameValuePair pair : params) {
if (first)
first = false;
else
result.append("&");
result.append(URLEncoder.encode(pair.getName(), "UTF-8"));
result.append("=");
result.append(URLEncoder.encode(pair.getValue(), "UTF-8"));
}
return result.toString();
}
And this is how you can call the method with the parameters you want to POST :
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("paramName",
paramValue));
String insertResponse = makePOSTRequestNew(insertURL, nameValuePairs);
try this way hope it will help you,
ContentValues args = new ContentValues();
args.put("id", id);
args.put("productid", productid);
args.put("sequence_no", sequence_no);
args.put("quantity", quantity);
args.put("listprice", listprice );
try{
SQLiteDatabase database = databasehelper.getWritableDatabase();
database.insertWithOnConflict(tableName, null, args, SQLiteDatabase.CONFLICT_REPLACE);
}catch(Exception e){
e.printStackTrace();
}
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("redirect_uri", redirect);
params.put("code", code); // your INSTAGRAM code received
Set set = params.entrySet();
Iterator i = set.iterator();
StringBuilder postData = new StringBuilder();
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

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());
