Answer 3

Using urllib2 to download a page.

谷歌将阻止此请求，因为它将尝试阻止所有机器人。向请求添加用户代理。

import urllib2
user_agent = 'Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_4; en-US) AppleWebKit/534.3 (KHTML, like Gecko) Chrome/6.0.472.63 Safari/534.3'
headers = { 'User-Agent' : user_agent }
req = urllib2.Request('http://www.google.com', None, headers)
response = urllib2.urlopen(req)
page = response.read()
response.close() # its always safe to close an open connection

You can also use pyCurl

import sys
import pycurl

class ContentCallback:
        def __init__(self):
                self.contents = ''

        def content_callback(self, buf):
                self.contents = self.contents + buf

t = ContentCallback()
curlObj = pycurl.Curl()
curlObj.setopt(curlObj.URL, 'http://www.google.com')
curlObj.setopt(curlObj.WRITEFUNCTION, t.content_callback)
curlObj.perform()
curlObj.close()
print t.contents
