阿里大鱼简单发送短信功能.net core版

阿里大鱼还未提供 .net core 版sdk，但提供了相关api，下面是.net core版实现，只是简单发送短信功能：

}

发送短信时：          

var parms = new dictionary<string, string>();
  parms.add(constants.extend, "123456");
  parms.add(constants.rec_num, "138********");
  parms.add(constants.sms_free_sign_name, "阿里大鱼");
  parms.add(constants.sms_param, "{\"code\":\"1234\",\"product\":\"阿里大鱼\"}");
  parms.add(constants.sms_template_code, "sms_10000000");

var req = smshelper.sendsms("http://gw.api.taobao.com/router/rest", "appkey", "appsecret", datetime.now, parms);
