使用 jMeter 测试 Laravel.. 读取配置时出错
Testing Laravel with jMeter.. Error reading config
我正在尝试 运行 在使用 Laravel 5.5 作为后端开发的简单 Web 中进行性能测试。
这是一个简单的测试，只有一个示例获得主页。当测试开始时，一切正常，但更早或更晚，请求随机出现错误 500。无论并发用户数是 2 还是 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 > Select jmx
- 配置用户定义的变量
- 运行 测试
包含 5 个用户的失败示例的屏幕截图。
正在审核laravel.log，错误是：

所以，我认为，问题是有时，配置读取失败并获取在 config/app.php.
中指定的默认值
有没有人遇到过这个问题或者可以使用提供的 jmx 测试一个 Laravel 项目？
谢谢！
这是一个 laravel configuration issue:
您需要执行php artisan config:cache命令。并检查环境配置。
Add an env configuration option to your app.php configuration file that looks like the following:
'env' => env('APP_ENV', 'production'),
Caching And Env
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.
If you are calling envfrom 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.
我正在尝试 运行 在使用 Laravel 5.5 作为后端开发的简单 Web 中进行性能测试。
这是一个简单的测试，只有一个示例获得主页。当测试开始时，一切正常，但更早或更晚，请求随机出现错误 500。无论并发用户数是 2 还是 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 > Select jmx
- 配置用户定义的变量
- 运行 测试
包含 5 个用户的失败示例的屏幕截图。

所以，我认为，问题是有时，配置读取失败并获取在 config/app.php.
中指定的默认值有没有人遇到过这个问题或者可以使用提供的 jmx 测试一个 Laravel 项目？
谢谢！
这是一个 laravel configuration issue:
您需要执行php artisan config:cache命令。并检查环境配置。
Add an env configuration option to your app.php configuration file that looks like the following:
'env' => env('APP_ENV', 'production'),
Caching And Env
If you are using the
config:cachecommand during deployment, you must make sure that you are only calling theenvfunction from within your configuration files, and not from anywhere else in your application.If you are calling
envfrom within your application, it is strongly recommended you add proper configuration values to your configuration files and callenvfrom that location instead, allowing you to convert yourenvcalls toconfigcalls.
