PHP Laravel同时执行许多ajax请求将给出"加密密钥"服务器错误

Question

请帮助我解决这个简单的PHP ajax请求问题，因为它在我的项目中阻止了我很长时间。

同时向 PHP 控制器发送许多(如 100 个(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 AppHttpControllers;
class abcController extends Controller{
    public function loadSingle($elementId){
        return 'abc';
    }
}

然后在浏览器中，我同时发送 ajax GET 请求 100 次：

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

而且输出结果不稳定，我得到了 5 分(变化(中的 100 分，出现服务器错误。在日志文件中它说：

对于这个问题，我应该错过了一些配置。请帮助我解决这个问题。非常感谢。

Answer 1

首先，确保您已设置APP_KEY .env文件。

现在，如果您确实设置了它，请尝试运行php artisan config:cache缓存配置。此外，如果您直接在应用程序中使用APP_KEY，请确保您使用的是相应的配置键。

Answer 2

如果在 .env 文件中新创建的密钥通过以下方式

php artisan key:generate

没有帮助，那么您应该清除缓存并通过以下方式为您的 Laravel 配置制作新的缓存

php artisan config:cache

不要忘记在配置更改后重新启动Apache/nginx。
