python - urlopen 不适用于特定的 url

Question

大家好，我是编程的新手，所以请原谅我的任何新手错误。我试图在 python 3.6 中使用 urllib 来查找网页上的字符串和我找到的解决方案 here适用于我测试过的大多数网页，例如:

from urllib.request import urlopen
>>>string = 'google'
>>>url = 'https://google.com/'
>>>webp=urlopen(url).read()
>>>isfound = webp.find(string.encode('utf-8'))
>>>print(isfound)
186

但是当我尝试使用 URL https://chan.sankakucomplex.com/ 时(NSFW) 我遇到了很多错误，但我不知道为什么。我已经尝试将我的 DNS 更改为 8.8.8.8，但这并没有改变任何东西。

错误: Traceback (most recent call last):

Answer 1

urllib.error.URLError: <urlopen error [Errno 11004] getaddrinfo failed>

这告诉我您的 DNS 服务器拒绝将文本地址 (chan.sankakucomplex.com) 转换为 IP 地址。这不是 Python 的问题。

您能否从运行 Python 代码的同一台机器上运行的 Web 浏览器访问该站点？
