问题描述

I´m trying to run a performance test in a simple web developed with Laravel 5.5 as backend. 我正在尝试在以Laravel 5.5作为后端开发的简单网络中运行性能测试。

It´sa simple test, only one sample getting the home page. 这是一个简单的测试，只有一个样本可以访问主页。 When the test begins, all works correctly, but earlier or later, randomly, the request gets Error 500. No matters the concurrent users, ocurrs with 2 or 10 users. 测试开始时，所有操作均正常运行，但随机执行，则该请求会出现错误500。无论并发用户是多少，都会出现2个或10个用户。

This is the plan used: jMeter Laravel-Core Simple Request JMX 这是使用的计划： jMeter Laravel-Core Simple Request JMX

  • Download jMeter 3.13 下载jMeter 3.13
  • File > Open > Select jmx 文件>打开>选择jmx
  • Configure the User Defined Variables 配置用户定义的变量
  • Run test 运行测试

Screenshot with a fail example with 5 users. 屏幕截图，其中包含5个用户的失败示例。 5个用户失败

Reviewing the laravel.log, the error is: 查看laravel.log，错误是：

In my .env file, I have APP_ENV=local not APP_ENV=production and the APP_KEY is set correctly (all earlier requests load correctly). 在我的.env文件中，我有APP_ENV=local而不是APP_ENV=production ，并且APP_KEY设置正确（所有早期请求均正确加载）。 I tried setting APP_ENV=production , but the problem persist... 我尝试设置APP_ENV=production ，但是问题仍然存在...

So, I think, the problem it´s that sometimes, the config read fails and get the default values especifies in the config/app.php. 因此，我认为问题在于有时config读取失败并获得config / app.php中指定的默认值。

Has anyone had this problem or can test a Laravel project with the jmx provided? 有没有人遇到这个问题，或者可以使用提供的jmx测试Laravel项目？

Thanks! 谢谢！

This is a laravel configuration issue : 这是一个laravel配置问题 ：

You need to execute php artisan config:cache command. 您需要执行php artisan config:cache命令。 and check env configuration. 并检查环境配置。

Add an env configuration option to your app.php configuration file that looks like the following: 将env配置选项添加到您的app.php配置文件中，如下所示： 

'env' => env('APP_ENV', 'production'),

Caching And Env 缓存和环境

If you are using the config:cache command during deployment, you must make sure that you are only calling the env function from within your configuration files, and not from anywhere else in your application. 如果在部署过程中使用config:cache命令，则必须确保仅从配置文件中调用env函数，而不从应用程序中的任何其他位置调用env函数。

If you are calling env from within your application, it is strongly recommended you add proper configuration values to your configuration files and call env from that location instead, allowing you to convert your env calls to config calls. 如果要从应用程序内部调用env ，则强烈建议您向配置文件中添加适当的配置值，然后从该位置调用env ，从而允许您将env调用转换为config调用。
