python发送HTTP请求的方法小结

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()

希望本文所述对大家的Python程序设计有所帮助。
