【未解决】Flask-Sockets中实现对于websocket的连接的监听打开open关闭close发送信息message

折腾:

【已解决】如何利用Flask-Sockets实现websocket的地址中带参数

之后,

需要去:

希望搞清楚,如何监听到,connected,disconnected的时间

并且进行判断是否是有效的用户:

userId是存在的,token是有效的。

实现:

对于想要打开一个websocket,比如此处的:

ws://115.29.173.126:21085/users/user5/token6

想要在打开的时候,去判断此连接是否有效。

用户是否有效,token是否有效。

所以想要去监听此连接的connect,即open的事件

然后去判断和处理

以及:

对于断开连接on disconnect, disconnected,closed,close

也去监听。

搜:

flask-sockets里面好像没有:

socketio.on

之类的写法啊

Adding web sockets to Flask apps

hasenj / flask-sockets-tutorial / source / main.py — Bitbucket

作者的源码里面:

flask-sockets/flask_sockets.py at master · kennethreitz/flask-sockets

也没找到关于:

ws的closed的变量

后来注意到Log中有:

ws=<geventwebsocket.websocket.WebSocket object at 0x7f1f997fade0>

-》所以可以去找geventwebsocket.websocket.WebSocket

geventwebsocket.websocket.WebSocket

gevent-websocket/websocket.py at master · jgelens/gevent-websocket

里面就有:

gevent-websocket 0.9.5 : Python Package Index

-》

想起来了:

之前用:

pip install flask-sockets

去安装flask-sockets的时候,就安装了对应的依赖的库:

gevent-websocket-0.9.5

从示例代码中就可以看到:

是有对应的

on_open

on_message

on_close

的函数的。

对于此处代码:

    server = pywsgi.WSGIServer((”, 21085), app, handler_class=WebSocketHandler)

去搜搜:

pywsgi.WSGIServer

然后添加对应的类,作为resource去处理不同的ws端口

另外再去看看:

geventwebsocket

的:

感觉这个才是我要的:

带class去处理对应端口的open,on_message

但是人家用的是tornado。。。

WebSocketApplication

可以看到有对应的:

on_close

on_message

【总结】

对于Flask-Sockets,最终放弃了去实现监听对应的websocket的open和close的事件。
