post data dengan rest client volley di android

pertama tambah library di android, caranya:

pada list Gradle scripts expand dan pilih build.gradle (Module: app)

tambahkan list berikut di baris paling bawah compile 'com.android.volley:volley:1.0.0'

untuk melakukan request dapat dilakukan dengan script ini

private void doLogin(final String username, final String password) { //Log.d("host: ", username); StringRequest request = new StringRequest(Request.Method.POST, host + "auth/", new Response.Listener<String>() { @Override public void onResponse(String response) { showProgress(false); JSONObject result; try { result = new JSONObject(response); JSONObject res = result.getJSONObject("result"); Integer code = res.getInt("code"); if (code == 200) { Intent intent = new Intent(LoginActivity.this, MainActivity.class); startActivity(intent); finish(); } else { String msg = res.getString("msg"); Toast.makeText(LoginActivity.this, msg, Toast.LENGTH_LONG).show(); } //Log.d("response code: ", code); } catch (JSONException e) { e.printStackTrace(); } } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { showProgress(false); Toast.makeText(LoginActivity.this, error.getMessage().toString(), Toast.LENGTH_LONG).show(); } } ) { @Override protected Map<String, String> getParams() throws AuthFailureError { //create parameters Map<String, String> params = new Hashtable<String, String>(); //add parameters params.put("username", username); params.put("password", password); params.put("api_key", host_api.getApi_key()); params.put("secret_key", host_api.getSecret_key()); return params; } }; request.setRetryPolicy(new DefaultRetryPolicy(5000,2,2)); RequestQueue req_queue = Volley.newRequestQueue(this); req_queue.add(request); }

untuk variabel-variabelnya silahkan disesuaikan
