Question

我已将Symfony 4应用程序部署到Google App Engine（灵活的环境）中。

该构建似乎已经成功，但是在Chrome中加载该应用程序会导致错误：

Oops! An Error Occurred
The server returned a "500 Internal Server Error".
Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

我不明白此错误。我该如何解决？

Answer 1

Symfony将其错误写到var / log而不是stdout（您可以配置它），但这意味着您需要ssh进入实例并阅读var / log / prod.log以获得关于什么的更多详细信息。导致500错误。该文档说明了如何：

https://cloud.google.com/appengine/docs/flexible/php/debugging-an-instance

在这种情况下，日志为：

[2019-02-03 09:23:41] request.CRITICAL: Uncaught PHP Exception Symfony\Component\DependencyInjection\Exception\EnvNotFoundException: "Environment variable not found: "OAUTH_GOOGLE_CLIENT_ID"." at /app/vendor/symfony/dependency-injection/EnvVarPr
ocessor.php line 96 {"exception":"[object] (Symfony\\Component\\DependencyInjection\\Exception\\EnvNotFoundException(code: 0): Environment variable not found: \"OAUTH_GOOGLE_CLIENT_ID\". at /app/vendor/symfony/dependency-injection/EnvVarProcesso
r.php:96)"} []

收到错误消息后，很容易看到问题出在哪里，这似乎尚未配置OAUTH_GOOGLE_CLIENT_ID环境。

env_variables:
    APP_ENV: "prod"
    APP_SECRET: 
    OAUTH_GOOGLE_CLIENT_ID: 
    OAUTH_GOOGLE_CLIENT_SECRET:

请确保在app.yaml中设置了这些（出于安全/最佳实践的考虑，请勿将其提交到git中，但您可以将其提交为空白以获取信息）

AppEngine-客户端关闭了keepalive连接
