Laravel 5 如何顯示像會話閃存這樣的油門消息？

Question

我使用laravel 5.4，我想限制如下路線的請求

Route::group(['middleware' => ['throttle:2']], function () {

    Route::post('/xxx', 'TestController@getTest');

});

它運行良好，但是當收到“Too Many Attempts”時。 它顯示在空白頁上。 有沒有辦法在刀片視圖中顯示這樣的會話 Flash 消息？

Answer 1

因此，一種簡單的方法是更改​​您的油門中間件。

首先，創建一個新的中間件來擴展基本油門中間件，如下所示：

namespace App\Http\Middleware;

use Illuminate\Routing\Middleware\ThrottleRequests as 
BaseThrottleRequests;

class ThrottleRequests extends BaseThrottleRequests
{
}

然后在 app/Http/Kernel.php 中更改您的油門中間件：

'throttle' => \App\Http\Middleware\ThrottleRequests::class

它現在將使用你自己的油門中間件，因為它是從 laravel 的中間件擴展而來的，它具有它的功能並且像以前一樣工作。

然后，查看基類內部，您會發現buildResponse會在嘗試次數過多的情況下構建響應。 因此，您只需要在中間件中覆蓋它：

protected function buildResponse($key, $maxAttempts)
{
    $retryAfter = $this->limiter->availableIn($key); // This gives you the number of seconds before the next time it is available

    return redirect('test')->with('error', '...'); // You can use redirect() and all those stuffs as you would normally do to redirect the user and set a session message
}

Answer 2

創建一個中間件，例如 CustomThrottleRequests 在其中擴展 ThrottleRequests 中間件

覆蓋句柄方法

 public function handle($request, Closure $next, $maxAttempts = 60, $decayMinutes = 1, $prefix = '')
{
    $key = $prefix.$this->resolveRequestSignature($request);

    $maxAttempts = $this->resolveMaxAttempts($request, $maxAttempts);

    if ($this->limiter->tooManyAttempts($key, $maxAttempts)) {
        $retryAfter = $this->getTimeUntilNextRetry($key);
         $retryAfter is in seconds
         //here you can change response according to requirements
        return redirect()->back()->withInput()->with('error','Too Many Attempts. Please try after '.$retryAfter .' seconds');
    }

    $this->limiter->hit($key, $decayMinutes * 60);

    $response = $next($request);

    return $this->addHeaders(
        $response, $maxAttempts,
        $this->calculateRemainingAttempts($key, $maxAttempts)
    );
}

現在在 app/Http/Kernel.php

  change from 
  'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
   to
 'throttle' => CustomThrottleRequests::class,
