python - 返回 header 之前脚本超时 : application. py

Question

我一直在尝试使用他们的弹性beanstalk服务在aws上部署我的flask应用程序，但我没有运气。我尝试将应用程序重命名为应用程序或导入为应用程序。我尝试向 httpf.conf 添加不同的内容。但是，没有运气。

有什么想法吗？

这是我正在使用/遇到的一些示例。

谢谢!

这是因为您在代码中的某个位置启动了内置 Flask 开发服务器。从消息中可以明显看出:

Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

通常这是因为 app.run() 正在被调用，但这在您所显示的内容中并不明显。

无论哪种方式，您都不应该启动 Flask 开发服务器，因为 Apache 下的 mod_wsgi 充当 WSGI 服务器。
