导入错误:没有模块名称urllib2

时间:2010-05-08 01:58:52

标签: python python-3.x 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?

urllib2 documentation中所述:

  

urllib2模块已拆分为Python 3中名为urllib.requesturllib.error的几个模块。将源代码转换为Python 3时,2to3工具将自动调整导入。

所以你应该说

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

您当前编辑的代码示例不正确,因为您说urllib.urlopen("http://www.google.com/")而非urlopen("http://www.google.com/")

对于使用Python 2(测试版本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())

以上在3.3中对我不起作用。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'))

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)

虽然我已在相应版本中测试了两个代码。

注意:urllib2在Python 3中不再可用

您可以尝试以下代码。

import urllib.request 
res = urllib.request.urlopen('url')
output = res.read()
print(output)

您可以从此link了解有关urllib.request的更多信息。

使用:urllib3

import urllib3
http = urllib3.PoolManager()
r = http.request('GET', 'url')
print(r.status)
print( r.headers)
print(r.data)
