1.地址，文件地址和播放地址需要抓取

2.'Cookie':  'csrf'网页刷新后需要更新，大量爬虫可以使用代理ip和伪造User-Agent，或者js逆向后续更新。

出现错误，data = requests.get(url=mp3path).content  五颗红星 原来哪里我添加headers后get不了导致失败，后面把headers去掉后就能用了

  data = requests.get(mp3path,headers=headers).content

 

 

1.演示一下用免费代理ip爬虫

        {"http":"36.248.133.145:9999"},
        {"http":"42.56.238.117:9999"},
        {"http":"36.249.119.34:9999"},
        {"http":"58.22.177.60:9999"}
    ]
    for proxy in proxy_list:
        print(proxy)
        # 遍历出来的ip创建处理器
        # 代理处理器
        proxy_handler=urllib.request.ProxyHandler(proxy)
        #创建自己的opener
        opener=urllib.request.build_opener(proxy_handler)   
        try:
            # 拿着代理ip去发送请求
            data = opener.open(url,timeout=1).read()
            print("haha")
        except Exception as e:
            print(e)    

creat_proxy_handler()
