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()
