Question

大家好，我对编程很新，所以请原谅我任何noob错误。我正在尝试在 python 3.6 中使用 urllib 在网页上找到一个字符串，我找到的解决方案here对我测试的大多数网页都非常有效，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/（NSFW）时，我遇到了大量错误，我不知道为什么。我已经尝试将DNS更改为8.8.8.8，但这并未改变任何内容。

错误： Traceback (most recent call last): File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\urllib\request.py", line 1318, in do_open encode_chunked=req.has_header('Transfer-encoding')) File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\http\client.py", line 1239, in request self._send_request(method, url, body, headers, encode_chunked) File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\http\client.py", line 1285, in _send_request self.endheaders(body, encode_chunked=encode_chunked) File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\http\client.py", line 1234, in endheaders self._send_output(message_body, encode_chunked=encode_chunked) File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\http\client.py", line 1026, in _send_output self.send(msg) File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\http\client.py", line 964, in send self.connect() File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\http\client.py", line 1392, in connect super().connect() File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\http\client.py", line 936, in connect (self.host,self.port), self.timeout, self.source_address) File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\socket.py", line 704, in create_connection for res in getaddrinfo(host, port, 0, SOCK_STREAM): File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\socket.py", line 743, in getaddrinfo for res in _socket.getaddrinfo(host, port, family, type, proto, flags): socket.gaierror: [Errno 11004] getaddrinfo failed During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:/Users/-/Desktop/python/searcher/stackex.py", line 5, in <module> webp=urlopen(url).read() File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\urllib\request.py", line 223, in urlopen return opener.open(url, data, timeout) File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\urllib\request.py", line 526, in open response = self._open(req, data) File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\urllib\request.py", line 544, in _open '_open', req) File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\urllib\request.py", line 504, in _call_chain result = func(*args) File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\urllib\request.py", line 1361, in https_open context=self._context, check_hostname=self._check_hostname) File "C:\Users\-\AppData\Local\Programs\Python\Python36\lib\urllib\request.py", line 1320, in do_open raise URLError(err) urllib.error.URLError: <urlopen error [Errno 11004] getaddrinfo failed>

Answer 1

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

这告诉我你的DNS服务器拒绝将文本地址（chan.sankakucomplex.com）翻译成IP地址。这不是Python的问题。

您是否可以从运行python代码的同一台计算机上运行的Web浏览器访问该网站？

urlopen不适用于特定网址
