对Python发送带header的http请求方法详解


						简单的header 





import urllib2

 

request = urllib2.Request('http://example.com/')

request.add_header('User-Agent', 'fake-client')

response = urllib2.urlopen(request)

print request.read()



包含较多元素的header





import urllib,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; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.89 Safari/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()
