I am building a RESTful API with Laravel 5.1 - When a post request is made, I validate the input, if the input is not valid, I throw an exception.

Current Response Sample:

    "message": "{\"email\":[\"The email field is required.\"]}",
    "status_code": 400

How to make my response look like this:

    "message": {
        "email": "The email field is required."
    "status_code": 400

Here's how I throw the exception:

$validator = Validator::make($this->request->all(), $this->rules());

if ($validator->fails()) {
    throw new ValidationFailedException($validator->errors());

I think the best way to validate the form in laravel is using Form Request Validation .You can overwrite the response method in App\Http\Request.php class. Request.php

namespace App\Http\Requests;

abstract class Request extends FormRequest
    public function response(array $errors)
        return $this->respond([
                'status_code'   => 400 ,                                 
                'message'          => array_map(function($errors){         
                        foreach($errors as $key=>$value){
                            return $value;                           

     * Return the response 
    public function respond($data , $headers=[] ){
        return \Response::json($data);
