VerifyCsrfToken.php 中的错误异常

Question

ErrorException in VerifyCsrfToken.php line 135:

Trying to get property of non-object

是什么导致我出现上述错误？我有一个自定义中间件。

我不确定要 post 哪些文件，因为它发生在我登录时，在我看来我有

{!! csrf_field() !!}

            }else{
                return redirect()->guest('admin/login');
            }
            return $next($request);

Answer 1

public function handle($request, Closure $next, $guard = null)
{
    if (Auth::guard($guard)->guest()) {
        if ($request->ajax()) {
            return response('Unauthorized.', 401);
        }

        return redirect()->guest('admin/login');
    }
    // they are not a guest, so lets allow the request
    // to continue to the application
    return $next($request);
    // we are returning the response from where ever it started
    // from down the pipeline
}

如果请求满足某些条件，我们将通过不调用 $next($request) 来阻止它继续深入应用程序。在任何一种情况下，我们最终都会 returning 一个 Response class 的某种形式的响应，希望如此。

CSRF 中间件正在接受一个请求，对其进行检查，如果通过，则将请求更深入地传递到应用程序中。此调用 return 是一个响应，它也想添加一个 cookie，但为此它需要特定类型的对象。

要很好地参与此堆栈，您必须期待收到请求并 return 返回响应。

To pass the request deeper into the application (allowing the middleware to "pass"), simply call the $next callback with the $request.

It's best to envision middleware as a series of "layers" HTTP requests must pass through before they hit your application. Each layer can examine the request and even reject it entirely.
