python 之 模拟GET/POST提交

以 POST/GET 方式向 http://127.0.0.1:8000/test/index 提交数据。

 # coding:utf-8
 import httplib
 import urllib

 class HttpClient(object):
     METHOD_POST = 'POST'
     METHOD_GET  = 'GET'
     REQUEST_HEADER = {'Content-type': 'application/x-www-form-urlencoded',
                       'Accept': 'text/plain'}

     def __init__(self, host, port=80):
         self.host = host
         self.port = port

     def doPost(self, body, url='', headers=REQUEST_HEADER):
         return self._doRequest(self.METHOD_POST, urllib.urlencode(body), url, headers)

     def doGet(self, body=None, url='', headers={}):
         return self._doRequest(self.METHOD_GET, body, url, headers)

     def _doRequest(self, method, body, url, headers):
         try:
             conn = httplib.HTTPConnection(self.host, self.port)
             conn.request(method, url, body, headers)
             response = conn.getresponse()
             result = response.read()
             conn.close()
         except:
             raise
         finally:
             conn.close()
         return response.status, result

 def send():
     client = HttpClient('127.0.0.1', '')
     params = {'message': 'test',
               'username' : 'testUser',
               'password': 'testPwd'
               }
     print (client.doPost(params, '/test/index'))    # post方式
     print (client.doGet(params, '/test/index'))     # get方式

 if __name__ == '__main__':
     send()

第二种方法：

import urllib
import urllib2

test_data = {'ServiceCode':'aaaa','b':'bbbbb'}   # get方法没有
test_data_urlencode = urllib.urlencode(test_data) #get方法没有

requrl = "http://127.0.0.1/test/index"

req = urllib2.Request(url = requrl,data =test_data_urlencode)
print req

res_data = urllib2.urlopen(req)
res = res_data.read()
print res
