Question

i am trying to make a post request to authorize user.

This is my route.php

Route::post('/user/login', 'OwnerController@login');

Here my login method:

$login_by = Input::get('login_by');
    $device_token = Input::get('device_token');
    $device_type = Input::get('device_type');

    if (Input::has('email') && Input::has('password')) {
        $email = Input::get('email');
        $password = Input::get('password');
        $validator = Validator::make(
                        array(
                    'password' => $password,
                    'email' => $email,
                    'device_token' => $device_token,
                    'device_type' => $device_type,
                    'login_by' => $login_by
                        ), array(
                    'password' => 'required',
                    'email' => 'required|email',
                    'device_token' => 'required',
                    'device_type' => 'required|in:android,ios',
                    'login_by' => 'required|in:manual,facebook,google'
                        )
        );

        if ($validator->fails()) {
            $error_messages = $validator->messages()->all();
            $response_array = array('success' => false, 'error' => 'Invalid Input', 'error_code' => 401, 'error_messages' => $error_messages);
            $response_code = 200;
            Log::error('Validation error during manual login for owner = ' . print_r($error_messages, true));
        } else {

                        $response_array = array('success' => false, 'error' => 'Login by mismatch', 'error_code' => 417);
                        $response_code = 200;
                    } else {
                        if ($owner->device_type != $device_type) {

        }
         return Response::make(json_encode($response_array,JSON_PRETTY_PRINT))->header('Content-Type', "application/json");

but when i tried to access this url from my ios project using AFNETWORKING: Login Link Localhost

I got this error:

Is there any specific way to make a webservice like method and print json ? Is there a problem in IOS call or in Web output?

Thanks
