laravel - 如何处理 Laravel Passport 中的 OAuth 异常？

Question

我正在研究 laravel 护照包。当我撤销 token 并访问经过身份验证的端点时，它会引发异常。

日志文件包含“资源所有者或授权服务器拒绝了请求”。为了处理异常，我创建了 OAuth 中间件并在其中放置了异常代码，如此链接中所述: https://www.kingpabel.com/oauth2-exception-custom-error-message/

public function handle($request, Closure $next)
    {
        //return $next($request);
         try {
            $response = $next($request);
            // Was an exception thrown? If so and available catch in our middleware
            if (isset($response->exception) && $response->exception) {
                throw $response->exception;
            }
            return $response;
        } catch (OAuthException $e) {
            $data = [
//                'error' => $e->errorType,
//                'error_description' => $e->getMessage(),
                'error' => 'Custom Error',
                'error_description' => 'Custom Description',
            ];
            return \Response::json($data, $e->httpStatusCode, $e->getHttpHeaders());
        }
    }

我想以 json 格式返回错误，例如:

{
    "error": "Token is invalid!"
}

如果有人在这方面指导我，我将不胜感激。谢谢，

我设法通过这种方式得到它，在handler.php

use League\OAuth2\Server\Exception\OAuthServerException;
use Illuminate\Auth\AuthenticationException;
....

public function report(Exception $exception)
    {   
        if ($exception instanceof OAuthServerException || $exception instanceof AuthenticationException) {

            if(isset($exception->guards) && isset($exception->guards()[0]) ==='api')
            response()->json('Unauthorized', 401) ;
            else if ($exception instanceof OAuthServerException)
            response()->json('Unauthorized', 401) ;
        }

        parent::report($exception);
    }

然后为了防止浏览器上的跨源错误添加了一个中间件如下注意:使中间件在生产中安全内核.php

protected $middleware = [
        ....
        \App\Http\Middleware\Cors::class,
    ];

cors.php

use Closure;

class Cors
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {

        return $next($request)
        ->header('Access-Control-Allow-Origin', '*')
          ->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS')
          ->header('Access-Control-Allow-Headers',' Origin, Content-Type, Accept, Authorization, X-Request-With')
          ->header('Access-Control-Allow-Credentials',' true');

    }
}
