如果Laravel 5.5中的请求授权失败，则重定向 [英] Redirect if request authorization is failed in Laravel 5.5

问题描述

如果授权失败，我正在尝试重定向请求.我有以下代码:

I am trying to redirect request if authorization is failed for it. I have following code:

class ValidateRequest extends Request{
    public function authorize(){
        // some logic here...
        return false;
    }

    public function rules(){ /* ... */}

    public function failedAuthorization() {
        return redirect('safepage');
    }
}

默认情况下，我被重定向到403错误页面，但是我想指定一些特定的路由.我注意到方法failedAuthorization()正在运行，但是redirect()方法不起作用...

By default I am redirected to the 403 error page, but I would like to specify some specific route. I noticed that method failedAuthorization() is run, but redirect() method does not work...

以前，此代码可与Laravel 5.1配合使用，但是我使用了forbiddenResponse()方法来重定向错误的请求.如何使用新的LTS版本修复它?

Previously this code worked well with Laravel 5.1 but I used forbiddenResponse() method to redirect wrong request. How can I fix it with new LTS version?

推荐答案

看起来不可能直接从自定义ValidateRequest类进行redirect().我发现的唯一解决方案是创建自定义异常，然后在Handler类中对其进行处理.因此，现在它可以与以下代码一起使用:

Looks like it is impossible to redirect() directly from the custom ValidateRequest class. The only solution that I found is create custom exception and than handle it in the Handler class. So, now it works with following code:

app/Requests/ValidateRequest.php

class ValidateRequest extends Request{
    public function authorize(){
        // some logic here...
        return false;
    }

    public function rules(){
        return [];
    }

    public function failedAuthorization() {
        $exception = new NotAuthorizedException('This action is unauthorized.', 403);

        throw $exception->redirectTo("safepage");
    }
}

app/Exceptions/NotAuthorizedException.php

<?php

namespace App\Exceptions;

use Exception;

class NotAuthorizedException extends Exception
{
    protected $route;

    public function redirectTo($route) {
        $this->route = $route;

        return $this;
    }

    public function route() {
        return $this->route;
    }
}

和 app/Exceptions/Handler.php

...
public function render($request, Exception $exception){
    ...

    if($exception instanceof NotAuthorizedException){
            return redirect($exception->route());
        }

    ...
}

因此，它可以工作，但是比我预期的要慢得多.简单的测量表明，处理和重定向花费2.1 s，而使用Laravel 5.1时，相同的操作(和相同的代码)仅花费0.3 s

So, it works, but much more slower than I expected... Simple measuring shows that handling and redirecting take 2.1 s, but with Laravel 5.1 the same action (and the same code) takes only 0.3 s

将NotAuthorizedException::class添加到$dontReport属性完全没有帮助...

Adding NotAuthorizedException::class to the $dontReport property does not help at all...

更新

在php 7.2中运行速度更快，耗时0.7 s

It runs much more faster with php 7.2, it takes 0.7 s
