Pythone抓取:抓取大多数情况属于get请求，即直接从对方服务器上获取数据。
Requests：
import requests
response = requests.get(url)
content = requests.get(url).content
print "response headers:", response.headers
print "content:", content
Urllib2：
import urllib2
response = urllib2.urlopen(url)
content = urllib2.urlopen(url).read()
print "response headers:", response.headers
print "content:", content
Httplib2：
import httplib2
http = httplib2.Http()
response_headers, content = http.request(url, ‘GET‘)
print "response headers:", response_headers
print "content:", content
