python urlopen输出错误

Question

cj=http.cookiejar.CookieJar()
opener=build_opener(HTTPCookieProcessor(cj))
data={'uid' : uid , 'password' : password }   #uid is username to the website
data=urllib.parse.urlencode(data)
data=data.encode(encoding='utf-8')
url='http://202.117.120.37/xdjwWebNew/Servlet/UsersControl' # url is a link to a specific page
request=Request(url,data)
response=opener.open(request)
response.geturl()

输出：

'http://docs.python.org/2/library/urllib2.html?highlight=urllib'

我不是什么问题。 任何建议都会有所帮助。

Answer 1

你想要输出什么？如果您想要链接的html页面，请使用response.read()。通过doc

This supports the following methods: read(), readline(), readlines()...
...these methods have the same interface as for file objects

The geturl() method returns the real URL of the page.
