78websoeket集成到flask框架

# server端
from flask import Flask
from flask_socketio import SocketIO

app = Flask(__name__)
app.config["SECRET_KEY"] ="gsagdgasg436fgsdh"
socketio = SocketIO(app)

# 当客户端连接时触发
@socketio.on("connect")
def handle_connect():
    print('Client connected')


# 当客户端断开连接时触发
@socketio.on("disconnect")
def handle_disconnect():
    print("Client disconnected")


# 处理客户端发送的消息
@socketio.on("message")
def handle_message(data):
    print("client -> server message:",data)
    #向客户端发送响应
    socketio.emit("response",{'data':'Server reeived:'+data})


if __name__ == '__main__':
    print("socketio 服务启动")
    socketio.run(app,host='0.0.0.0',port=5000)

 

# 客户端
import socketio

# 创建socket.IO客户端实例
sio = socketio.Client()


# 连接成功时触发
@sio.event
def connect():
    print("Connected to server")
    # 向服务器发送消息
    sio.emit("message","hello,Server")


# 收到服务器响应时触发
@sio.event
def response(data):
    print("server -> client:",data)


# 断开连接时触发
@sio.event
def disconnect():
    print("disconnected from server")
    exit(0)


# 连接到服务器
sio.connect('http://localhost:5000')

# 保持连接时触发
sio.wait()

 

通过socketio实例和flask实例绑定，在使用flask api接口的同时也支持websocket实时双向通信
