Android JSON HttpClient to send data to PHP server with HttpResponse

Question

I am currently trying to send some data from and Android application to a php server (both are controlled by me).

There is alot of data collected on a form in the a

Answer 1

StringEntity s = new StringEntity(c.toString());
s.setContentEncoding("UTF-8");
s.setContentType("application/json");
request.setEntity(s);

Answer 2

After lots of reading and searching I have found the problem to be with, I beleive magic_quotes_gpc being enabled on the server.

Thus, using:

json_decode(stripslashes($_POST['vehicle']));

In my example above removes the slashes and allows the JSON to be decoded properly.

Still not sure why sending a StringEntity causes a 403 error?

Answer 3

Try this code it works for me

public void postData(String result,JSONObject obj) {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpParams myParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(myParams, 10000);
HttpConnectionParams.setSoTimeout(myParams, 10000);

String json=obj.toString();

try {

    HttpPost httppost = new HttpPost(result.toString());
    httppost.setHeader("Content-type", "application/json");

    StringEntity se = new StringEntity(obj.toString()); 
    se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
    httppost.setEntity(se); 

    HttpResponse response = httpclient.execute(httppost);
    String temp = EntityUtils.toString(response.getEntity());
    Log.i("tag", temp);


} catch (ClientProtocolException e) {

} catch (IOException e) {
}

}

Answer 4

Try this code it works perfectly

*For HttpClient class* download jar file "httpclient-4.3.6.jar" and put in libs folder then
Compile:   dependencies {compile files('libs/httpclient-4.3.6.jar')}

repositories {
        maven {
            url "https://jitpack.io"
        }
    }

then call HttpClient class this AsyncTask Like this:

private class YourTask extends AsyncTask { private String error_msg = "Server error!";

    private JSONObject response;



    @Override
    protected Boolean doInBackground(String... params) {
        try {
            JSONObject mJsonObject = new JSONObject();
            mJsonObject.put("user_id", "user name");
            mJsonObject.put("password", "123456");
            String URL=" Your Link"

            //Log.e("Send Obj:", mJsonObject.toString());

            response = HttpClient.SendHttpPost(URL, mJsonObject);
            boolean status = response != null && response.getInt("is_error") == 0; // response

            return status;
        } catch (JSONException | NullPointerException e) {
            e.printStackTrace();
            mDialog.dismiss();
            return false;
        }
    }

    @Override
    protected void onPostExecute(Boolean status) {
       // your code

    }
}

Change

(String url = "http://www.server.com/MainPage.php";)

to

(String url = "http://www.server.com/MainPage.php?";)

Question mark at the end is necessary when you're trying to send parameters to php script.
