PHP Laravel同時執行多個ajax請求會給出一個'加密密鑰'服務器錯誤

Question

請幫我解決這個簡單的PHP ajax請求問題，因爲它阻塞了我很長時間的項目。

向PHP控制器同時發送許多（如100個）ajax GET請求會給出'沒有指定應用程序加密密鑰'。錯誤。 在Laravel，我創建了以下路由器：

<?php 
Route::get('/database/abc/load_single/{elementId}','abcController@loadSingle'); 

和abcController定義爲：

<?php 
namespace App\Http\Controllers; 
class abcController extends Controller{ 
    public function loadSingle($elementId){ 
     return 'abc'; 
    } 
} 

然後，在瀏覽器中，我在同一時間發送AJAX GET請求100次：

for (var index=0; index<100; index++){ 
    $.ajax({ 
     type: "GET", 
     url: urlPrefix + "database/abc/load_single/10001", 
    }); 
} 

並且輸出結果不穩定，我得到了5（它變化）出100個服務器錯誤。在日誌文件中它說：

應該有一些配置，我錯過了這個問題。 請幫我解決這個問題。非常感謝。

Answer 1

首先，請確保您的APP_KEY已設置爲您的.env文件。

現在，如果你真的設置了它，請嘗試運行php artisan config:cache來緩存配置。此外，如果您直接在您的應用中使用APP_KEY，請確保您正在使用相應的配置密鑰。
