Ali big fish simply send SMS function. NET Core Edition _ Practical Tips

Ali Big Fish has not yet provided the. NET Core Edition SDK, but has provided the relevant API, the following is the. NET Core Edition implementation, but simply sends the short message function:

When sending text messages:

var parms = new dictionary<string, string> ();
  Parms. ADD (Constants.extend, "123456");
  Parms. ADD (Constants.rec_num, "138********");
  Parms. ADD (Constants.sms_free_sign_name, "Ali Big Fish");
  Parms. ADD (Constants.sms_param, "{\" code\ ": \" 1234\ "," product\ ": \" Ali Big Fish "}");
  Parms. ADD (Constants.sms_template_code, "sms_10000000");

var req = smshelper.sendsms ("Http://gw.api.taobao.com/router/rest", "Appkey", "Appsecret", DateTime.Now, parms);
