Python3错误：“导入错误：没有模块名称urllib2”

这是我的代码：

import urllib2.request response = urllib2.urlopen("http://www.google.com") html = response.read() print(html) 

任何帮助？

Answer 1

如urllib2文档中所述 ：

urllib2模块已经在Python 3 urllib.error几个模块，分别是urllib.request和urllib.error 。 2to3工具将自动适应导入将源代码转换为Python 3。

所以你应该说

 from urllib.request import urlopen html = urlopen("http://www.google.com/") print(html) 

您目前正在编辑的代码示例不正确，因为您在说urllib.urlopen("http://www.google.com/")而不是urlopen("http://www.google.com/") 。

Answer 2

对于使用Python 2（testing版本2.7.3和2.6.8）和Python 3（3.2.3和3.3.2+）的脚本，请尝试：

 #! /usr/bin/env python try: # For Python 3.0 and later from urllib.request import urlopen except ImportError: # Fall back to Python 2's urllib2 from urllib2 import urlopen html = urlopen("http://www.google.com/") print(html.read()) 

Answer 3

3.3上面这个不适合我。 试试这个（YMMV等）

 import urllib.request url = "http://www.google.com/" request = urllib.request.Request(url) response = urllib.request.urlopen(request) print (response.read().decode('utf-8')) 

Answer 4

Python 3：

 import urllib.request wp = urllib.request.urlopen("http://google.com") pw = wp.read() print(pw) 

Python 2：

 import urllib import sys wp = urllib.urlopen("http://google.com") for line in wp: sys.stdout.write(line)

虽然我已经testing了两个版本的代码。

一些标签的完成，用于显示Python 2与Python 3中包的内容。

在Python 2中：

 In [1]: import urllib In [2]: urllib. urllib.ContentTooShortError urllib.ftpwrapper urllib.socket urllib.test1 urllib.FancyURLopener urllib.getproxies urllib.splitattr urllib.thishost urllib.MAXFTPCACHE urllib.getproxies_environment urllib.splithost urllib.time urllib.URLopener urllib.i urllib.splitnport urllib.toBytes urllib.addbase urllib.localhost urllib.splitpasswd urllib.unquote urllib.addclosehook urllib.noheaders urllib.splitport urllib.unquote_plus urllib.addinfo urllib.os urllib.splitquery urllib.unwrap urllib.addinfourl urllib.pathname2url urllib.splittag urllib.url2pathname urllib.always_safe urllib.proxy_bypass urllib.splittype urllib.urlcleanup urllib.base64 urllib.proxy_bypass_environment urllib.splituser urllib.urlencode urllib.basejoin urllib.quote urllib.splitvalue urllib.urlopen urllib.c urllib.quote_plus urllib.ssl urllib.urlretrieve urllib.ftpcache urllib.re urllib.string urllib.ftperrors urllib.reporthook urllib.sys 

在Python 3中：

 In [2]: import urllib. urllib.error urllib.parse urllib.request urllib.response urllib.robotparser In [2]: import urllib.error. urllib.error.ContentTooShortError urllib.error.HTTPError urllib.error.URLError In [2]: import urllib.parse. urllib.parse.parse_qs urllib.parse.quote_plus urllib.parse.urldefrag urllib.parse.urlsplit urllib.parse.parse_qsl urllib.parse.unquote urllib.parse.urlencode urllib.parse.urlunparse urllib.parse.quote urllib.parse.unquote_plus urllib.parse.urljoin urllib.parse.urlunsplit urllib.parse.quote_from_bytes urllib.parse.unquote_to_bytes urllib.parse.urlparse In [2]: import urllib.request. urllib.request.AbstractBasicAuthHandler urllib.request.HTTPSHandler urllib.request.AbstractDigestAuthHandler urllib.request.OpenerDirector urllib.request.BaseHandler urllib.request.ProxyBasicAuthHandler urllib.request.CacheFTPHandler urllib.request.ProxyDigestAuthHandler urllib.request.DataHandler urllib.request.ProxyHandler urllib.request.FTPHandler urllib.request.Request urllib.request.FancyURLopener urllib.request.URLopener urllib.request.FileHandler urllib.request.UnknownHandler urllib.request.HTTPBasicAuthHandler urllib.request.build_opener urllib.request.HTTPCookieProcessor urllib.request.getproxies urllib.request.HTTPDefaultErrorHandler urllib.request.install_opener urllib.request.HTTPDigestAuthHandler urllib.request.pathname2url urllib.request.HTTPErrorProcessor urllib.request.url2pathname urllib.request.HTTPHandler urllib.request.urlcleanup urllib.request.HTTPPasswordMgr urllib.request.urlopen urllib.request.HTTPPasswordMgrWithDefaultRealm urllib.request.urlretrieve urllib.request.HTTPRedirectHandler In [2]: import urllib.response. urllib.response.addbase urllib.response.addclosehook urllib.response.addinfo urllib.response.addinfourl

这在python3中为我工作：

 import urllib.request htmlfile = urllib.request.urlopen("http://google.com") htmltext = htmlfile.read() print(htmltext) 

Answer 7

在python 3中，获取文本输出：

 import io import urllib.request response = urllib.request.urlopen("http://google.com") text = io.TextIOWrapper(response)
