python 3.12
换成别的网址比如百度就是可以的，课程里的鱼C网站就不行，换成论坛地址和https://ilovefishc.com/这个地址都是不行，搜索了相关问题，import了ssl然后ssl._create_default_https_context = ssl._create_unverified_context了也不行[/free]

这个错误是由于SSL证书验证失败导致的。在Python 3.12中，urllib库默认会验证HTTPS请求的SSL证书，如果证书 ...

我说了，import了ssl按照这个操作的不行，而且按照您说的我又试了一遍还是不行呀

问题分析：
根据错误信息提示，这个问题是由于SSL证书验证失败导致的。对于某些网站，Python默认会进行SSL ...

restart shell 又走了一遍可以了 谢谢
请问这个禁用验证了，如何再次重新开启验证呢？另外每次都需要import sll，然后ssl._create_default_https_context = ssl._create_unverified_context么？岂不是很麻烦

貌似没问题啊

我这里确实每次都需要ssl._create_default_https_context = ssl._create_unverified_context这个一下
