Question

我正在尝试编译此project-“ AirTNG应用程序：第1部分-使用Twilio进行工作流自动化-ASP.NET MVC”。

我在Notifier.cs第40行中看到一个_client.SendMessage。但是它没有建立，因为TwilioRestClient类中似乎没有任何方法可以解析为“ SendMessage”。

[使用Twilio程序集的15.1.0版。]

以下是通知程序的代码：

using System;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web.Services.Description;
using AirTNG.Web.Domain.Twilio;
using AirTNG.Web.Models;
using AirTNG.Web.Models.Repository;
using Twilio;
using Twilio.Clients;


namespace AirTNG.Web.Domain.Reservations
{
    public interface INotifier
    {
        Task<Message> SendNotificationAsync(Reservation reservation);
    }

    public class Notifier : INotifier
    {
        private readonly TwilioRestClient _client;
        private readonly IReservationsRepository _repository;

        public Notifier() : this(
            new TwilioRestClient(Credentials.AccountSid, Credentials.AuthToken),
            new ReservationsRepository()) { }

        public Notifier(TwilioRestClient client, IReservationsRepository repository)
        {
            _client = client;
            _repository = repository;
        }

        public async Task<Message> SendNotificationAsync(Reservation reservation)
        {
            var pendingReservations = await _repository.FindPendingReservationsAsync();
            if (pendingReservations.Count() > 1) return null;

            var notification = BuildNotification(reservation);
            return _client.SendMessage(notification.From, notification.To, notification.Messsage);
        }

        private static Notification BuildNotification(Reservation reservation)
        {
            var message = new StringBuilder();
            message.AppendFormat("You have a new reservation request from {0} for {1}:{2}",
                reservation.Name,
                reservation.VacationProperty.Description,
                Environment.NewLine);
            message.AppendFormat("{0}{1}",
                reservation.Message,
                Environment.NewLine);
            message.Append("Reply [accept] or [reject]");

            return new Notification
            {
                From = PhoneNumbers.Twilio,
                To = reservation.PhoneNumber,
                Messsage = message.ToString()
            };
        }
    }
}

下面是我的packages.config的内容，就像对所有软件包的最新稳定版进行更新之后的样子。

Answer 1

您应该使用Twilio最新的nuget软件包Twilio.AspNet.Mvc版本5.9.7。因为您使用的版本具有对较早版本的ASP.NET MVC的依赖关系，但是其余软件包的依赖项取决于.NET的较新版本，例如Newtonsoft.Json 11.0.x。

请改用以下版本的5.9.7：https://www.nuget.org/packages/Twilio.AspNet.Mvc/5.9.7

并正确链接依赖项。

原始示例使用API版本4编写。为了使其与版本5兼容，我进行了一些更改。

更新通知程序代码：

using System;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using AirTNG.Web.Domain.Twilio;
using AirTNG.Web.Models;
using AirTNG.Web.Models.Repository;
using Twilio.Clients;
using Twilio.Rest.Api.V2010.Account;

namespace AirTNG.Web.Domain.Reservations
{
    public interface INotifier
    {
        Task<MessageResource> SendNotificationAsync(Reservation reservation);
    }

    public class Notifier : INotifier
    {
        private readonly TwilioRestClient _client;
        private readonly IReservationsRepository _repository;

        public Notifier() : this(
            new TwilioRestClient(Credentials.AccountSid, Credentials.AuthToken),
            new ReservationsRepository())
        {
        }

        public Notifier(TwilioRestClient client, IReservationsRepository repository)
        {
            _client = client;
            _repository = repository;
        }

        public async Task<MessageResource> SendNotificationAsync(Reservation reservation)
        {
            var pendingReservations = await _repository.FindPendingReservationsAsync();
            if (pendingReservations.Count() > 1) return null;

            var notification = BuildNotification(reservation);

            var message = await MessageResource.CreateAsync(
                body: notification.Messsage,
                from: notification.From,
                to: notification.To,
                client: _client
            );

            return message;
        }

        private static Notification BuildNotification(Reservation reservation)
        {
            var message = new StringBuilder();
            message.AppendFormat("You have a new reservation request from {0} for {1}:{2}",
                reservation.Name,
                reservation.VacationProperty.Description,
                Environment.NewLine);
            message.AppendFormat("{0}{1}",
                reservation.Message,
                Environment.NewLine);
            message.Append("Reply [accept] or [reject]");

            return new Notification
            {
                From = PhoneNumbers.Twilio,
                To = reservation.PhoneNumber,
                Messsage = message.ToString()
            };
        }
    }
}
