我正在开发一个Django应用程序，到现在为止我已经将它部署到App Engine标准环境，但是随后我开始使用Google Cloud Vision Python库，并由于一些限制，我切换到灵活环境。
我的代码在我的本地机器上用python manage.py runserver ，但是当我将它部署到App Engine时，我得到了以下内容
<html> <head> <title>502 Bad Gateway</title> </head> <body bgcolor="white"> <center> <h1>502 Bad Gateway</h1> </center> <hr> <center>nginx</center> </body> </html>
当我研究这个问题的时候，我发现我需要改变这里所说的nginx设置。
要应用的Nginx设置
# Tune nginx keepalives to work with the GCP HTTP(S) Load Balancer: keepalive_timeout 650; keepalive_requests 10000;
但我无法find办法做到这一点。 我也是后端开发的新手，所以我没有太多的经验。
这是我的app.yaml文件
runtime: python api_version: 1 threadsafe: yes env: flex entrypoint: gunicorn -b :$PORT app.wsgi runtime_config: python_version: 3 handlers: - url: /static static_dir: static - url: .* script: app.wsgi.application builtins: - django_wsgi: on
我尝试设置entrypoint以下，但它没有工作。
entrypoint: gunicorn --keep-alive 650 -b :$PORT app.wsgi
编辑1：此错误只发生POST请求。
编辑2：这是与http请求的错误日志：

这是https请求的错误日志：

我相信Nginx并没有真正的需要。 您基于自己的链接与HTTP负载平衡器有关，而不是App Engine Flexible。
在App Engine上灵活使用Django应用程序的例子可以在这里find。
看来你的应用在本地testing机器上运行不好。 如果这样做，通过遵循“从标准环境向灵活环境迁移服务”在线指南 ，将它从标准环境应用程序迁移到柔性变得容易。
