Is there anyway to handle authorization token mismatch error

Question

i am new to laravel and laravel-passport, i was following this article on medium here

everything going as i exactly want, until i tried to handle the error if the user sent wrong authorization token in details method

here is the error:

InvalidArgumentException

Route [login] not defined.

i am using laravel 5.7 and passport 7.1 which is the latest

i've tried

first snippet

to try and catch the error in show method

second snippet

to handle the token mismatch exception in /app/exceptions/handler.php it wasn't a token mismatch exception i guess

third snippet

even to miss up a little with laravel core at Handler.php file

in the unauthenticated method but no hope

/routes/api.php

Route::get('user/login', 'AuthController@login');

// user
Route::get('users/find', 'UserController@index');

//here i am trying this route
//with wrong authorization tocken
Route::middleware('auth:api')->group(function () {
    Route::get('user', 'UserController@show');
});
Route::post('user', 'UserController@store');
Route::put('user/{id}', 'UserController@update');
Route::delete('user/{id}', 'UserController@destroy');

/UserController.php

public function show()
{

    if(Auth::check()){
        $user = auth()->user();
        return response()->json(['user'=>auth()->user()], 200);        
    }else{
        return response()->json("can't connect", 400);
    }

}

First Snippet public function show() {

    try {
        $user = auth()->user();
    } catch (\Throwable $th) {
        return response()->json("can't connect", 400);
    }

    return response()->json(['user'=>auth()->user()], 200);

}

Second Snippet /app/exceptions/handler.php

public function render($request, Exception $exception)
{
    if ($exception instanceof TokenMismatchException) {
        return "Token error";
    }

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

Third Snippet

\vendor\laravel\framework\src\Illuminate\Foundation\Exceptions\Handler.php

protected function unauthenticated($request, AuthenticationException $exception)
{
    return $request->expectsJson()
                ? response()->json(['message' => $exception->getMessage()], 401)
                : redirect()->guest($exception->redirectTo() ?? route('login'));
}

Error Snippet (might be useful)

public function route($name, $parameters = [], $absolute = true)
{
    if (! is_null($route = $this->routes->getByName($name))) {
        return $this->toRoute($route, $parameters, $absolute);
    }

    // the following line is highlighted 
    throw new InvalidArgumentException("Route [{$name}] not defined.");
}

i expect the return to be a json not this error template

cause you might figured out i am trying to build a restful API

You can create a custom error and in render method add standard response you can return the json you want.

For example create a new exception App/Exceptions/CustomInvalidTokenException.php:

<?php

namespace App\Exceptions;

use Exception;
use Illuminate\Http\Request;

class CustomInvalidTokenException extends Exception
{
    /**
     * Render the exception into an HTTP response.
     *
     * @param  \Illuminate\Http\Request
     * @return \Illuminate\Http\Response
     */
    public function render(Request $request)
    {
        return response()->json([
            'error' => $this->getMessage(),
            'status' => 0
        ], 500);
    }
}

Then in your controller throw it and internally it will render the exception response for you :

<?php 


try{
    // something
}
catch(TokenMismatchException $e){

    throw new CustomInvalidTokenException('Invalid token found');
}

If you want to handle the exception gobally and not on specific route then you can do the throw new CustomInvalidTokenException inside handler.php
