python-Flask和Flask-SocketIO集成和导入错误

我正在尝试将Flask-SocketIO与我的Flask应用程序集成.

由于某种原因,我收到了由
从..导入我在events.py中拥有的socketio,我不确定为什么.

我将不胜感激提供的任何帮助.

app.py

from factory import create_app
app = create_app()

factory.py

from flask import Flask
from flask.ext.socketio import SocketIO
from flask.ext.login import LoginManager
import os
from celery import Celery

lm = LoginManager()
socketio = SocketIO()
lm.login_view = 'main.login'
lm.session_protection = 'strong'


def create_app():
    app = Flask(__name__)
    app.config.from_object(os.environ.get('APP_CONFIG'))  # export APP_CONFIG=settings.Development
    lm.init_app(app)

    from project.main import main as main_blueprint

    app.register_blueprint(main_blueprint)
    socketio.init_app(app)

    return app

main / ____ init____.py

from flask import Blueprint

main = Blueprint('main', __name__)
import views, events

main / events.py

# from __future__ import absolute_import
from uuid import uuid4
from flask import current_app, session, request
from flask.ext.socketio import emit, disconnect
from .. import socketio

@socketio.on('status', namespace='/events')
def events_message(message):
    print 'socketio.on: status'
    emit('status', {'status': message['status']})


@socketio.on('disconnect request', namespace='/events')
def disconnect_request():
    print 'socketio.on: disconnect request'
    emit('status', {'status': 'Disconnected!'})
    disconnect()


@socketio.on('connect', namespace='/events')
def events_connect():
    print 'socketio.on: connect'
    websocket_id = str(uuid4())
    session['websocket_id'] = websocket_id
    current_app.clients[websocket_id] = request.namespace
    emit('websocket_id', {'websocket_id': websocket_id})

解决方法:

将main / ____ init____.py重命名为main / __ init__.py,您可以执行以下操作：

from . import socketio

如果像你说的那样在__init__.py中定义了socketio.但是,它看起来像是在factory.py中定义的,在这种情况下,您需要执行以下操作：

from ..factory import socketio
