python有一个httplib的库，提供了很方便的方法实现GET和POST请求，只需要简单的组织一下即可。

python发送get请求代码：

#!/usr/bin/env python
#coding=utf8
  
import httplib
  
httpClient = None
  
try:
    httpClient = httplib.HTTPConnection('localhost', 80, timeout=30)
    httpClient.request('GET', '/test.php')
  
    #response是HTTPResponse对象
    response = httpClient.getresponse()
    print response.status
    print response.reason
    print response.read()
except Exception, e:
    print e
finally:
    if httpClient:
        httpClient.close()

发送POST请求

#!/usr/bin/env python
#coding=utf8
  
import httplib, urllib
  
httpClient = None
try:
    params = urllib.urlencode({'name': 'tom', 'age': 22})
    headers = {"Content-type": "application/x-www-form-urlencoded"
                    , "Accept": "text/plain"}
  
    httpClient = httplib.HTTPConnection("localhost", 80, timeout=30)
    httpClient.request("POST", "/test.php", params, headers)
  
    response = httpClient.getresponse()
    print response.status
    print response.reason
    print response.read()
    print response.getheaders() #获取头信息
except Exception, e:
    print e
finally:
    if httpClient:
        httpClient.close()
