通过python manage.py runserver
运行我的应用程序时,它的运行无懈可击。但是,当我尝试将其部署到Google App Engine时,突然停顿了。

我经历了很多线程,但找不到问题。 (作为参考,dev_appserver.py
模拟器会产生相同的问题,这是一件好事。)

默认情况下,App Engine在名为app
的文件中查找main.py
变量。您有两种选择:将WSGI应用程序放置在App Engine期望的位置,或定义自定义入口点:
您可以创建一个名为main.py
的文件,该文件具有一个app
变量,该变量只需从正确的位置导入并作为别名即可。
from demosite.wsgi import main as app
来自https://cloud.google.com/appengine/docs/standard/python3/config/appref:
entrypoint
:可选。应用启动时执行的命令。为了使您的应用程序接收HTTP请求,entrypoint
应该包含一个命令,该命令启动一个Web服务器,该服务器侦听PORT环境变量指定的端口。如果您未指定entrypoint
,则App Engine将配置并启动Gunicorn网络服务器。
默认情况下是这样:
entrypoint: gunicorn -b :$PORT main:app
您将需要以下内容:
entrypoint: gunicorn -b :$PORT demosite.wsgi:main
有关应用程序启动的更多详细信息,请参见此处:https://cloud.google.com/appengine/docs/standard/python3/runtime#application_startup

只需将您的主Python应用程序(对我来说就是app.py)重命名为main.py。 Google Cloud需要main.py才能开始该过程。
答案 2 :(得分:0)
添加:
main.py必须位于应用程序的根目录中,其中app.yaml在其中。
内容也可以是:
from mysite.wsgi import application
# App Engine by default looks for a main.py file at the root of the app
# directory with a WSGI-compatible object called app.
# This file imports the WSGI-compatible object of your Django app,
# application from mysite/wsgi.py and renames it app so it is discoverable by
# App Engine without additional configuration.
# Alternatively, you can add a custom entrypoint field in your app.yaml:
# entrypoint: gunicorn -b :$PORT mysite.wsgi
app = application

正如Farzad所说,只需将“ app.py”或“ application.py”或您将应用程序文件保存到“ main.py”的任何名称重命名。如果您无法更改,则使用相同的代码创建另一个项目,但是这次使用应用程序文件名作为“ main.py”
