通过代理服务器从C#/.NET调用Twilio API

我正在尝试从代理Web服务器后面运行C#sample twilio application.我的代理服务器需要身份验证.使用下面的代码,我能够成功地验证到代理服务器并进行Twilio调用.但是,Twilio给我返回了code 20003(权限被拒绝).我的AccountSID和AuthToken是正确的.下面的代码(不使用代理设置)在不需要Web代理服务器的其他环境中也可以正常工作.

我的问题类似于使用Java的问题和解决方案posted here,但是我无法使用C#/.NET复制Java修复程序.我正在使用.NET SDK 4.5

using System;
using Twilio;
using System.Net;

namespace TestTwilio
{
    class Program
    {
        static void Main(string[] args)
        {
            var accountSid = "xx";
            var authToken = "yy";

                var twilio = new TwilioRestClient(accountSid, authToken);twilio.Proxy = new System.Net.WebProxy("proxy.mycompany.com", 8080);
                    twilio.Proxy.Credentials = new NetworkCredential(“username”, “password”);

                var message = twilio.SendMessage("+1xxxxxxxxxx","+1xxxxxxxxxx", "Hello from C#");

            if (message.RestException != null)
            {
                var error = message.RestException.Message;
                Console.WriteLine(error);
                Console.WriteLine(message.RestException.MoreInfo);
                Console.WriteLine(message.Uri);
                Console.WriteLine(message.AccountSid);
                Console.Write("Press any key to continue.");
                Console.ReadKey();
            }
        }
    }
}

感谢您的帮助.

解决方法:

我能够使用直接API调用来绕过该问题.这不是解决原始问题的绝妙方法…因此仍在寻找正确的方法来解决此问题.以下是有效的代码.

using System;
using System.Net;
using RestSharp;

namespace TestTwilio
{
    class Program
    {
        static void Main(string[] args)
        {
            var client = new RestClient("https://api.twilio.com/2010-04-01/Accounts/{yourTwilioAccountSID}/SMS/Messages.json");
            client.Proxy = new System.Net.WebProxy("proxy.mycompany.com", 8080);
            client.Proxy.Credentials = new NetworkCredential("<<proxyServerUserName>>", "<<proxyServerPassword>>", "<<proxyServerDomain>>");
            var request = new RestRequest(Method.POST);
            request.Credentials = new NetworkCredential("<<your Twilio AccountSID>>", "<<your Twilio AuthToken>>");
            request.AddParameter("From", "+1xxxxxxxxxx");
            request.AddParameter("To", "+1xxxxxxxxxx");
            request.AddParameter("Body", "Testing from C# after authenticating with a Proxy");
            IRestResponse response = client.Execute(request);
            Console.WriteLine(response.Content);
            Console.ReadKey();
        }
    }
}
