【已解决】flask中实现websocket

需要在Flask中实现Websocket，以便于实现服务器和客户端的实时数据沟通。

搜：

flask websocket

参考：

Welcome to Flask-SocketIO’s documentation! — Flask-SocketIO documentation

GitHub – miguelgrinberg/Flask-SocketIO: Socket.IO integration for Flask applications.

GitHub – kennethreitz/flask-sockets: Elegant WebSockets for your Flask apps.

-》

总体感觉：

还是miguelgrinberg的Flask-SocketIO更好用。

不过，也还是先去简单对比一下：

【整理】Flask中的Websocket库：Flask-SocketIO vs Flask-Sockets

然后想办法去试试：Flask-SocketIO

【未解决】尝试使用Flask-SocketIO去实现Websocket

但是结果出错了：

【已解决】websocket启动出错：gunicorn.errors.HaltServer HaltServer App failed to load 4

再去想办法搞清楚，是不是：

Flask-Restful中，如何支持：Flask-Restful

搜：

希望用flask作为中介让python和js交互，大家有什么比较好的实践经验没？ – 知乎

【未解决】Simple WebSocket Client测试Flask的websocket显示OPENING且弹出undefined对话框

然后还是没解决。

继续去尝试：

【未解决】Flask-SocketIO测试出错：WebSocket connection to failed Error during WebSocket handshake Unexpected response code 400

要不抽空去试试：

到时候也可以考虑试试这个：

WebSocket with Flask

【已解决】使用Flask-Sockets去实现Flask中的Websocket

然后，对于之前安装了，但是没用到的库，都去删除掉：

pip uninstall Flask-SocketIO

pip uninstall python-socketio

pip uninstall python-engineio

注：

flask-sockets需要依赖gevent

好像gevent是需要依赖greenlet

的。

所以不删。
