使用 FlaskGroup 运行 gunicorn 时出错

问题描述

使用 python manage.py run -h 0.0.0.0 运行我的应用时，它工作正常。

这是我用来创建 FlaskGroup 的 manage.py 文件。

from flask.cli import FlaskGroup

from myapp import create_app

# create a flask app
app = create_app()
cli = FlaskGroup(create_app=create_app)

if __name__ == '__main__':
    cli()

我的 __init__.py 文件，其中包含传递给 FlaskGroup 的 create_app 函数：

from flask import Flask


def create_app():
    """Create a Flask application

    Returns:
        Flask: the Flask application
    """

    # instantiate the app
    app = Flask(__name__)

    # register blueprints
    from myapp.views import main_blueprint

    app.register_blueprint(main_blueprint)

    # shell context for flask cli
    app.shell_context_processor({"app": app})

    return app

如果我尝试将 gunicorn 与以下 wsgi.py 文件一起使用：

from manage import cli

if __name__ == '__main__':
    cli.run()

然后运行 ​​gunicorn 并随后发出请求，我收到此错误，我不确定如何解决。

gunicorn --bind=0.0.0.0:5000 wsgi:cli                                           ──(Thu,Apr08)─┘
