使用 twilio 向手机发送短信

Question

我正在尝试向手机发送短信。有人能告诉我为什么我的退货声明不起作用吗？如果我在 return 语句中只写字符串消息，那么它会显示该消息，但如果我使用下面提到的 return 语句，它就不起作用。有什么建议么？

using System;

using System.Collections.Generic;

using System.Web.Mvc;

using Twilio;

using Twilio.AspNet.Mvc;

using Twilio.Rest.Api.V2010.Account;

using Twilio.Types;

namespace TwilioSendSMS.Controllers

{

    public class SMSController : TwilioController

    {

        // GET: SMS ----- outbound----

        public ActionResult SendSms()

        {

            // Find your Account Sid and Auth Token at twilio.com/user/account

            const string accountSid = "ACxxxxxxxxx";

            const string authToken = "71xxxxxxxxxx";

            // Initialize the Twilio client

            TwilioClient.Init(accountSid, authToken);

            // make an associative array of people we know, indexed by phone number

            var people = new Dictionary<string, string>() {

                {"[phone]", "Kim"},

                {"[phone]", "Raj"}

            };

            // Iterate over all our friends

            foreach (var person in people)

            {

                // Send a new outgoing SMS by POSTing to the Messages resource

                MessageResource.Create(

                    from: new PhoneNumber("[phone]"), // From number, must be an SMS-enabled Twilio number

                    to: new PhoneNumber(person.Key), // To number, if using Sandbox see note above

                                                     // Message content

                    body: $"Hey {person.Value} Party is at 6PM! Don't forget to bring gift.");

            }

            //return Content($"Message has been sent!");

            return Content($"Sent message to {person.Value}");

        }

    }

}
