本文实例讲述了python发送HTTP请求的方法。分享给大家供大家参考。具体如下：

这里包含 Python 使用 GET/HEAD/POST 方法进行 HTTP 请求

1. GET 方法：

									>>> import httplib 

									>>> conn = httplib.HTTPConnection("www.python.org") 

									>>> conn.request("GET", "/index.html") 

									>>> r1 = conn.getresponse() 

									>>> print r1.status, r1.reason 

									200 OK 

									>>> data1 = r1.read() 

									>>> conn.request("GET", "/parrot.spam") 

									>>> r2 = conn.getresponse() 

									>>> print r2.status, r2.reason 

									404 Not Found 

									>>> data2 = r2.read() 

									>>> conn.close()

2. HEAD 方法：

									>>> import httplib 

									>>> conn = httplib.HTTPConnection("www.python.org") 

									>>> conn.request("HEAD","/index.html") 

									>>> res = conn.getresponse() 

									>>> print res.status, res.reason 

									200 OK 

									>>> data = res.read() 

									>>> print len(data) 

									0

									>>> data == '' 

									True

3. POST 方法：

									>>> import httplib, urllib 

									>>> params = urllib.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0}) 

									>>> headers = {"Content-type": "application/x-www-form-urlencoded", 

									...      "Accept": "text/plain"} 

									>>> conn = httplib.HTTPConnection("musi-cal.mojam.com:80") 

									>>> conn.request("POST", "/cgi-bin/query", params, headers) 

									>>> response = conn.getresponse() 

									>>> print response.status, response.reason 

									200 OK 

									>>> data = response.read() 

									>>> conn.close()
