第二次求助，到正则表达式2测试结果都是正常的。

三滑稽甲苯

感觉像是网络问题，不是正则表达式问题

Harold123

你的最后href网址错了，
第23行 child_href = domain + itt.group("href").strip("/")
拼接网址少了个‘‘/’’
https://www.dytt89.comi/105631.html
应该是
https://www.dytt89.com/i/105631.html

这是那个EXCEL用的正则吗

四楼正解，报错信息很明确了：socket.gaierror: [Errno 11001] getaddrinfo failed

域名拼接错了
