请帮我解决这个简单的PHP ajax请求问题，因为它长时间阻止了我的项目。
同时向PHP控制器发送许多（如100）ajax GET请求将给出“未指定应用程序加密密钥”。错误。在Laravel中，我创建了以下路由器：
<?php
Route::get('/database/abc/load_single/{elementId}','abcController@loadSingle');
并且abcController定义为：
<?php
namespace App\Http\Controllers;
class abcController extends Controller{
public function loadSingle($elementId){
return 'abc';
}
}
然后在浏览器中，我同时发送一个ajax GET请求100次：
for (var index=0; index<100; index++){
$.ajax({
type: "GET",
url: urlPrefix + "database/abc/load_single/10001",
});
}
并且输出结果不稳定，因为服务器错误，我得到了5（它变化了）100。在日志文件中它说：

应该有一些我错过了这个问题的配置。请帮我解决这个问题。非常感谢。
首先，请确保使用APP_KEY文件设置.env。
现在，如果您确实设置了它，请尝试运行php artisan config:cache来缓存配置。如果您在应用程序中直接使用APP_KEY，请确保使用相应的配置密钥。
如果在.env文件中新创建了密钥
php artisan key:generate
没有帮助，那么你应该清除你的缓存并为你的laravel配置制作新的缓存
php artisan config:cache
不要忘记在配置更改后重启apache / nginx。
