关于python：导入错误：没有模块名称urllib2

Import error: No module name urllib2

以下是我的代码：

1
2
3
4
5

import urllib2.request

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

有什么帮助吗？

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：

1
2
3
4
5
6
7
8
9
10
11

#! /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())

在第3.3节中，上述内容对我不起作用。试试这个(YMMV等)

1

4
5

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：

1
2
3
4
5

import urllib.request

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

Python 2：

1
2
3
4
5
6

import urllib
import sys

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

我已经在各自的版本中测试了这两个代码。

一些选项卡完成以显示python 2和python 3中包的内容。

在Python 2中：

在python 3中，要获取文本输出：

1

import io
import urllib.request

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

在python3为我工作：

1
2
3
4

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

最简单的解决方案：

在Python 3。

import urllib.request
url ="https://api.github.com/users?since=100"
request = urllib.request.Request(url)
response = urllib.request.urlopen(request)
data_content = response.read()
print(data_content)
