var options = {
                uri: 'http://vop.baidu.com/server_api',
                method: 'POST',
                headers: {"Content-Type": "application/json"},
                json:{
                    'format':'amr',
                    'rate':'8000',
                    'channel':1,
                    'token':token,//1
                    'cuid':userId,//2
                    'url':url//3这三个已经在前面定义
                }
            };
            function callback(error, res, body)  {
                if (!error && res.statusCode == 200{
                    response.send(info);
                }
    
            }
            request(options, callback);
