Using Httpclient and Httppost in Android with Post Parameters

Using HttpClient and HttpPost in Android with post parameters

have you tried doing it without the JSON object and just passed two basicnamevaluepairs?
also, it might have something to do with your serversettings

Update:
this is a piece of code I use:

InputStream is = null;
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("lastupdate", lastupdate)); 

try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(connection);
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
        Log.d("HTTP", "HTTP: OK");
    } catch (Exception e) {
        Log.e("HTTP", "Error in http connection " + e.toString());
    }

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.

android httpclient send post using the url as parameters?

You should read about HttpMethods.By definition, HttpPost pass the parameters on its body, and not in the query string. HttpGet in the other hand, should pass the parameters in the query string.
Besides, the entity here stands for the body.

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 send HTTP POST parameters using Android AsyncHttpClient?

You're probably missing the body-parser middleware.

var express = require('express')
var bodyParser = require('body-parser')

var app = express()

// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))

// parse application/json
app.use(bodyParser.json())

Sending HTTP Post Request with Android

You can use Http Client from Apache Commons. For example:

private class PostTask extends AsyncTask<String, String, String> {
  @Override
  protected String doInBackground(String... data) {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://<ip address>:3000");

    try {
      //add data
      List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
      nameValuePairs.add(new BasicNameValuePair("data", data[0]));
      httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
      //execute http post
      HttpResponse response = httpclient.execute(httppost);

    } catch (ClientProtocolException e) {

    } catch (IOException e) {

    }
  }
}

UPDATE

You can use Volley Android Networking Library to post your data. Official document is here.

I personally use Android Asynchronous Http Client for few REST Client projects.

Other tool that good to explore is Retrofit.
