Python构造发送POST请求

Python2.7 代码示例如下：

def post():    url = "http://127.0.0.1:8000/login.jsp"    postDict = {        'username' : 'test',        'password' : '123',        'login' : '登录'    }    opener = urllib2.build_opener(urllib2.HTTPHandler)    postData = urllib.urlencode(postDict)    request = urllib2.Request(url, data=postData)    request.get_method = lambda : "POST"    response = opener.open(request)    print response.read()
