Adds methods to your App\Exceptions\Handler to treat json responses. It is most useful if you are building APIs!

Installing and configuring

Install the package

$ composer require sfelix-martins/json-exception-handler

If you are not using Laravel 5.5 version add the JsonHandlerServiceProvider to your config/app.php providers array:

    'providers' => [
        ...
        SMartins\JsonHandler\JsonHandlerServiceProvider::class,
    ],

Publish the config to set your own exception codes

$ php artisan vendor:publish --provider="SMartins\JsonHandler\JsonHandlerServiceProvider"

Set your exception codes on config/json-exception-handler.php on codes array.

You can add more fields and codes to validation_fields array.

You can add too your models on lang packages to return the Not Found response translated correctly.

In resources/lang/vendor/exception/lang/$locale in exceptions file you can set on models array. Example:

    'models' => [
        'User' => 'Usuário',
        'Article' => 'Artigo',
    ]

Using

Use the trait on your App\Exception\Handler and add method jsonResponse() passing the $exception if $request expects a json response on render()method

use SMartins\JsonHandler\JsonHandler;

class Handler extends ExceptionHandler
{
    use JsonHandler;

    ...

    public function render($request, Exception $exception)
    {   
        if ($request->expectsJson()) {
            return $this->jsonResponse($exception);
        }

        return parent::render($request, $exception);
    }
    
    ...

Use sample

class UserController extends Controller
{
    ...

    public function store(Request $request)
    {
        // Validation
        $request->validate($this->rules); // on Laravel 5.5

        // or
        $this->validate($request, $this->rules);

        //and or
        Validator::make($request->all(), $this->rules)->validate();

        if (condition()) {
            // Generate response with http code and message
            abort(403, 'Action forbidden!');
        }

        if (anotherCondition()) {
            // Generate response with message and code
            throw new TokenMismatchException("Error Processing Request", 10);
        }
    }

    public function show($id)
    {
        // If not found the default response is called
        $user = User::findOrFail($id);
        
        // Gate define on AuthServiceProvider
        // Generate an AuthorizationException if fail
        $this->authorize('users.view', $user->id);
    }
