我正在尝试在 Heroku 上部署我的应用程序。我必须使用 Windows,而 gunicorn 将无法工作。我试过女服务员,每当我尝试加载任何页面时,它都会给我一个“模块不可调用”错误。

注意:到目前为止,我还没有在网络上部署它,heroku local在创建一个可公开访问的之前尝试过。它在localhost使用 PyCharm 时有效。

文件组织

/myapp
     requirements.txt
     Procfile
     /myapp
         /static
         /templates
         __init__.py

__init __.py

# encoding=utf-8
import click

from myapp.application import create_app
from myapp.application import db, login_manager

app = create_app()

from myapp.config import SQLALCHEMY_TRACK_MODIFICATIONS
from myapp.models import User
from myapp.views import *

app.add_url_rule('/home', HomePage.endpoint, 
      view_func=HomePage.as_view(HomePage.endpoint), methods=['GET','POST'])
# pages are defined in views.py

#other code

if __name__ == '__main__':
    # set debug to false when moving to production
    app.run()

Procfile

web: waitress-serve --port=5000 myapp:application

追溯:

知道如何解决这个问题吗?

在你的Procfile,尝试改变

web: waitress-serve --port=5000 myapp:application

web: waitress-serve --port=5000 myapp:app

的最后一个参数waitress-serveMODULE:OBJECT,其中OBJECT的应用程序对象在哪里MODULE。在这里,您已将应用程序命名为app

app = create_app()

(您并没有向我们展示您的所有代码,但它看起来myapp.application实际上是一个模块,而不是一个对象。您在示例代码中导入create_app,dblogin_managerfrom 它。)

女服务员有它自己的app,所以你需要app正确区分你的。@Chris 的回答向您展示了如何通过Procfile. 对于那些使用 Flask 的人来说,这是另一种方式:

应用程序/初始化.py

from flask import Flask

app = Flask(__name__, template_folder="some path", static_folder="another path")

主文件

from waitress import serve
from app import app as my_app  # renamed to distinguish from waitress' 'app'

if __name__ == "__main__":
    serve(my_app, host="localhost", port=5005)

这允许您将应用程序命名app在路由文件中,因为它与女服务员隔离

应用程序/routes.py

@app.route('/dothing1', methods=['POST', 'GET'])
def dothing1():
  pass
