Zappa正确设置`app_function`

Question

我的Flask应用程序有以下设置：

├── app
│   ├── __init__.py
│   └── routes.py
├── application.py
└── zappa_settings.json

application.py

import os
from app import config_app


if __name__ == "__main__":
    application = config_app(os.environ, __name__)
    application.run(threaded=True)

app/__init__.py

from flask import Flask

def config_app(config, name=__name__):
    app = Flask(__name__)
    app.config.from_mapping(config)
    ...
    return app

现在，我正在尝试将使用zappa的应用程序部署到亚马逊网络服务。当运行zappa init时，它会提示输入app_function，但是我不能完全确定要将其设置为什么。到目前为止我已经试过了

"app_function": "application.application"

这将在最后返回一个502错误。

运行zappa tail
