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', '8000')
    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
