PHP Laravelが同時に多くのAjaxリクエストを実行すると '暗号化キー'サーバーエラーが発生する

Question

この単純なPHP ajaxリクエストの問題は、私のプロジェクトで長い間ブロックされているので助けてください。

多くの（100のような）Ajax GETリクエストを同時にPHPコントローラに送信すると、「アプリケーション暗号化キーが指定されていません」と表示されます。エラー。 はLaravelでは、私は、次のルータに作成：

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

をしてabcControllerは次のように定義される：

ブラウザで次に

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

、私は同時に、AJAX GETリクエストを100回送信します。

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

出力結果が安定していないため、サーバーのエラーで100のうち5（変化する）があります。ログファイルには、次のように書かれています。

この問題では設定が必要です。 この問題を手伝ってください。どうもありがとう。

Answer 1

まず、.envファイルにAPP_KEYが設定されていることを確認してください。

実際に設定した場合は、php artisan config:cacheを実行してキャッシュ設定を試してみてください。また、APP_KEYをアプリで直接使用している場合は、代わりに対応する設定キーを使用していることを確認してください。
