websocket客户端的实现

# coding=utf-8import websocket  #第三方核心库from threading import Threadimport structfrom ctypes import *import multiprocessingimport os#服务端发送消息def on_message(ws, message):    pack_long = len(message)    #合并包信息    if pack_long > 0:        pack_long_form = "%sc" % pack_long        buffer = struct.unpack(pack_long_form,message)#链接错误def on_error(ws, error):    print(error)#链接关闭def on_close(ws):    print(ws)    print("### 关闭 ###")def on_open(ws):    # 发送心跳包    def run(*args):        for i in range(3):            time.sleep(10)            ws.send("以二进制的方法传送心跳信息", opcode=websocket.ABNF.OPCODE_BINARY)        time.sleep(1)        print("Thread terminating...")
