对Python发送带header的http请求方法详解
简单的header
importurllib2
request=urllib2.Request('http://example.com/')
request.add_header('User-Agent','fake-client')
response=urllib2.urlopen(request)
printrequest.read()
包含较多元素的header
importurllib,urllib2
url='http://example.com/'
headers={'Host':'example.com',
'Connection':'keep-alive',
'Cache-Control':'max-age=0',
'Accept':'text/html,*/*;q=0.01',
'X-Requested-With':'XMLHttpRequest',
'User-Agent':'Mozilla/5.0(X11;Linuxx86_64)AppleWebKit/537.36(KHTML,likeGecko)Chrome/41.0.2272.89Safari/537.36',
'DNT':'1',
'Referer':'http://example.com/',
'Accept-Encoding':'gzip,deflate,sdch',
'Accept-Language':'zh-CN,zh;q=0.8,ja;q=0.6'
}
data=None
req=urllib2.Request(url,data,headers)
response=urllib2.urlopen(req)
html=response.read()
