python之WebSocket通信爬虫协议请求方法

一、请求方法

import websocket
import _thread as thread
import time

def on_message(ws, message):
    """收到对方消息处理方法"""
    print("对方发来的消息：",message)
    time.sleep(5)   # 控制发送频率
    ws.send('ping')        # 我方决定再回一个消息

def on_error(ws, error):
    """ 错误处理方法 """
    print(error)

def on_close(ws,code,msg):
    """ 关闭处理方法 """
    print("代号：",code)
    print("对方关闭发来的消息：", msg)
    print("### 程序结束 ###")

def on_open(ws):
    """ 运行入口 """
    def run(*args):
        ws.send('ping')    # 我方发送第一个消息
    thread.start_new_thread(run, ())   # 开启线程
