爬取动态数据

安装

pip install websockets(是一个异步请求包)

pip install websocket-client（同步的包）

import asyncio
import websockets
import ssl
import certifi
# ssl验证(有需要的时候才用)
ssl_context=ssl.create_default_context()
ssl_context.load_verify_locations(certifi.where())
# https://finance.sina.com.cn/realstock/company/sh000001/nc.shtml
async def main():
    url='wss://hq.sinajs.cn/wskt?list=sh000001'
    # extra_headers给ws 传递请求头
    async with websockets.connect(url,extra_headers={'origin':
'https://finance.sina.com.cn','user-agent':
'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Safari/537.36'},ssl=ssl_context)as ws:
        # 发送讲求
        await ws.send("")
        # 接收数据
        while 1:
            ret=await ws.recv()#默认阻塞
            print(ret)
if __name__ == '__main__':
    # 开始运行
    asyncio.run(main())

结果
