Python websocket简单使用示例

socket编程

套接字，工作在传输层与应用层之间，通过TCP/UDP协议传输信息，分为客户端和服务端

模块：socket
使用步骤

服务端

1.创建socket对象：soc = socket.socket()
2.绑定IP和端口：soc.bind((ip,port))
3.设置监听：soc.listen()
4.等待客户端连接：soc.accept()

客户端

1.创建socket对象：soc = socket.socket()
2.连接服务器：soc.connect((ip,port))

公共方法

send() 发送消息
recv() 接收消息

示例：

import websocket
import json

###/Applications/Python\ 3.9/Install\ Certificates.command

class WebSockets():
    def __init__(self, url):
        self.url = url
        self.ws = websocket.WebSocket()
        self.ws.connect(url)

    def send_ws(self,data):
        self.ws.send(data)
        res = self.ws.recv()
        res1 = self.ws.recv()
        print(res, res1)


if __name__ == '__main__':
    ws = WebSockets(url='wss://localhost:8080/ws')
    param_data = {
    
    
        "token": "123456"
    }
    ws.send_ws(data=param_data)
    ws.close()

import json
from ws4py.client.threadedclient import WebSocketClient


###/Applications/Python\ 3.9/Install\ Certificates.command

class CG_Client(WebSocketClient):
    def opened(self):
        req = '{"token": "123456"}'
        self.send(req)


    def closed(self, code, reason=None):
        print("Closed down:",code,reason)

    def received_message(self, res):
        resp = json.loads(str(res))
        # data = resp['data']
        print("data:",resp)

if __name__ == '__main__':
    ws = None
    try:
        ws = CG_Client("wss://localhost:8080/ws")
        ws.connect()
        ws.run_forever()
    except KeyboardInterrupt:
        ws.close()
