使用jMeter测试Laravel。错误读取配置

Question

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。

这是一个简单的测试，只有一个样本可以访问主页。 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。

这是使用的计划： jMeter Laravel-Core Simple Request JMX

• 下载jMeter 3.13
• 文件>打开>选择jmx
• 配置用户定义的变量
• 运行测试

屏幕截图，其中包含5个用户的失败示例。

查看laravel.log，错误是：

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）。 我尝试设置APP_ENV=production ，但是问题仍然存在...

在其他经过测试的laravel项目中，错误是：

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。

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？

谢谢！

Answer 1

这是一个laravel配置问题 ：

您需要执行php artisan config:cache命令。 并检查环境配置。

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'),

缓存和环境

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。

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。
