How to Add Parameters in Android Http Post

How to add parameters in android http POST?

How to make an http POST and adding parameters.

how to add parameters? you must have something like.

// Add your data  
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);  
nameValuePairs.add(new BasicNameValuePair("userid", "12312"));  
nameValuePairs.add(new BasicNameValuePair("sessionid", "234"));  
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));  

This is a complete method:

public void postData() {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://www.yoursite.com/myexample.php");

try {
    // Add your data
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair("id", "12345"));
    nameValuePairs.add(new BasicNameValuePair("stringdata", "stackoverflow.com is Cool!"));
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    // Execute HTTP Post Request
    HttpResponse response = httpclient.execute(httppost);
    
   } catch (ClientProtocolException e) {
      // TODO Auto-generated catch block
   } catch (IOException e) {
      // TODO Auto-generated catch block
   }
}

How to post params in the body of HTTP post request?

How about:

public static String makePostRequest(String stringUrl, String payload, 
    Context context) throws IOException {
    URL url = new URL(stringUrl);
    HttpURLConnection uc = (HttpURLConnection) url.openConnection();
    String line;
    StringBuffer jsonString = new StringBuffer();

    uc.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
    uc.setRequestMethod("POST");
    uc.setDoInput(true);
    uc.setInstanceFollowRedirects(false);
    uc.connect();
    OutputStreamWriter writer = new OutputStreamWriter(uc.getOutputStream(), "UTF-8");
    writer.write(payload);
    writer.close();
    try {
        BufferedReader br = new BufferedReader(new InputStreamReader(uc.getInputStream()));
        while((line = br.readLine()) != null){
            jsonString.append(line);
        }
        br.close();
    } catch (Exception ex) {
        ex.printStackTrace();
    }
    uc.disconnect();
    return jsonString.toString();
}

Where payload is the body JSON string. You will also need to use an AsyncTask and run the above method in the doInBackground method, like so:

new AsyncTask<String, String, String>() {

    @Override
    protected String doInBackground(String... params) {
        try {
            String response = makePostRequest("http://www.example.com", 
                "{ exampleObject: \"name\" }", getApplicationContext());
            return "Success";
        } catch (IOException ex) {
            ex.printStackTrace();
            return "";
        }
    }

}.execute("");

Now you can use the response you get back from the server as well

Android httpPost with parameters and file

You must use a multipart http post, like in HTML forms. This can be done with an extra library.
See the post Sending images using Http Post for a complete example.

How to add parameters to HttpURLConnection using POST using NameValuePair

You can get output stream for the connection and write the parameter query string to it.

URL url = new URL("http://yoururl.com");
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("firstParam", paramValue1));
params.add(new BasicNameValuePair("secondParam", paramValue2));
params.add(new BasicNameValuePair("thirdParam", paramValue3));

OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
        new OutputStreamWriter(os, "UTF-8"));
writer.write(getQuery(params));
writer.flush();
writer.close();
os.close();

conn.connect();

...

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();
}

Send Post Request with params using Retrofit

I have found the solution. The issue was a problem in my classes structure. So i updated them like the following samples.

public class LandingPageReport {

    private ArrayList<LandingPageReportItem> GetDetailWithMonthWithCodeResult;

    // + Getter Setter methods
}

public class LandingPageReportItem {

    private String code;

    private String field1;

    // + Getter Setter methods
}

And then i use this retrofit configuration

@POST("/GetDetailWithMonthWithCode")
void getLandingPageReport(@Field("code") String code,
                          @Field("monthact") String monthact,
                          Callback<LandingPageReport> cb);

Sending Parameter using POST method in Android

try and use this code:

ServiceHandler sh = new ServiceHandler();
List<NameValuePair> params = new ArrayList<NameValuePair>();

@Override
protected void onPreExecute() {
    // TODO Auto-generated method stub
    super.onPreExecute();

    params.add(new BasicNameValuePair("pkey", "pvalue"));

}

@Override
protected String doInBackground(String... param) {
        // TODO Auto-generated method stub
        String json;
        try {
            json = sh.makeServiceCall(url, ServiceHandler.POST, params);

            Log.d("Response: ", "> " + json);

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return null;
    }

@Override
protected void onPostExecute(String result) {
    // TODO Auto-generated method stub
    super.onPostExecute(result);

    }
