我正在使用此代码来获取网站的 html 内容，

import urllib.request
import lxml.html as lh
req= urllib.request.Request("http://www.ip-adress.com/ip_tracer/157.123.22.11", 
headers={'User-Agent' : "Magic Browser"})
html = urllib.request.urlopen(req).read()
doc = lh.fromstring(html)
print (''.join(doc.xpath('.//*[@class="odd"]')[-1].text_content().split()))

我想获得组织：Zenith Data Systems。但它显示了一些错误

Traceback (most recent call last):
File "/usr/local/python3.2.3/lib/python3.2/urllib/request.py", line 1135, in do_open
h.request(req.get_method(), req.selector, req.data, headers)

raise err
File "/usr/local/python3.2.3/lib/python3.2/socket.py", line 395, in create_connection
sock.connect(sa)
socket.error: [Errno 111] Connection refused

在处理上述异常的过程中，又出现了一个异常：

Traceback (most recent call last):
File "ext.py", line 4, in <module>
html = urllib.request.urlopen(req).read()
File "/usr/local/python3.2.3/lib/python3.2/urllib/request.py", line 138, in urlopen
return opener.open(url, data, timeout)
File "/usr/local/python3.2.3/lib/python3.2/urllib/request.py", line 369, in open
response = self._open(req, data)
File "/usr/local/python3.2.3/lib/python3.2/urllib/request.py", line 387, in _open
'_open', req)
File "/usr/local/python3.2.3/lib/python3.2/urllib/request.py", line 347, in _call_chain
result = func(*args)
File "/usr/local/python3.2.3/lib/python3.2/urllib/request.py", line 1155, in http_open
return self.do_open(http.client.HTTPConnection, req)
File "/usr/local/python3.2.3/lib/python3.2/urllib/request.py", line 1138, in do_open
raise URLError(err)
urllib.error.URLError: <urlopen error [Errno 111] Connection refused>}

如何解决它。谢谢，

基本上，拒绝连接意味着只有注册用户才能访问该页面，或者服务器处于大量维护或类似原因。

从您上面的代码中，如果您想处理错误，您可以尝试使用 try 和除了下面的代码：

try:
    req= urllib.request.Request("http://www.ip-adress.com/ip_tracer/157.123.22.11",headers={'User-Agent' : "Magic Browser"})
    html = urllib.request.urlopen(req).read()
    doc = lh.fromstring(html)
    print (''.join(doc.xpath('.//*[@class="odd"]')[-1].text_content().split()))
except urllib.error.URLError as e:
    print(e.reason)
