python使用urllib2模拟http post，pythonurllib2,使用urllib2.ur

使用urllib2.urlopen方法模拟http post请求：

def post_data(app_para_dct):  content = ""  if app_para_dct:    para_dct = {}    para_dct['a'] = 'a'    para_dct['b'] = 'b'    url = """http://gw.api.taobao.com/router/rest"""    para_data = urllib.urlencode(para_dct)    f = urllib2.urlopen(url, para_data)    content = f.read()  return content

使用request.add_data添加post数据

def call_api(url, **kwargs):    req = urllib2.Request(url)    if kwargs:        req.add_data(urllib.urlencode(kwargs))    auth = 'Basic ' + base64.urlsafe_b64encode("%s:%s" % (USER, PASS))    req.add_header('Authorization', auth)    return urllib2.urlopen(req).read()
