从c＃应用程序发布消息以避免松弛

Question

我正在尝试在#general频道上发布消息，这是通过控制台应用程序进行的，但现在我正在使用MVC并且消息似乎没有发布。此外，早些时候我使用的是webhook URL，现在我正在使用我拥有的访问令牌。

 using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Linq;
using System.Net;
using System.Text;
using System.Web;

namespace SlackClient.Controllers
{
    public class SlackClient
    {
        private readonly Uri _uri;
        private readonly Encoding _encoding = new UTF8Encoding();

        public SlackClient(string urlWithAccessToken)
        {
            _uri = new Uri(urlWithAccessToken);
        }

        //Post a message using simple strings
        public void PostMessage(string text, string username = null, string channel = null)
        {
            Payload payload = new Payload()
            {
                Channel = channel,
                Username = username,
                Text = text
            };

            PostMessage(payload);
        }

        //Post a message using a Payload object
        public void PostMessage(Payload payload)
        {
            string payloadJson = JsonConvert.SerializeObject(payload);

            using (WebClient client = new WebClient())
            {
                NameValueCollection data = new NameValueCollection();
                data["payload"] = payloadJson;

                var response = client.UploadValues(_uri, "POST", data);

                //The response text is usually "ok"
                string responseText = _encoding.GetString(response);
            }
        }
    }

    //This class serializes into the Json payload required by Slack Incoming WebHooks
    public class Payload
    {
        [JsonProperty("channel")]
        public string Channel { get; set; }

        [JsonProperty("username")]
        public string Username { get; set; }

        [JsonProperty("text")]
        public string Text { get; set; }
    }
}

另一个类是SlackClientTest.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace SlackClient.Controllers
{
    public class SlackClientTest
    {
        void TestPostMessage()
        {
            string urlWithAccessToken = "https://srishti2604.slack.com/services/hooks/incoming-webhook?token=my-tokenHere.";

            SlackClient client = new SlackClient(urlWithAccessToken);

            client.PostMessage(username: "Mr. Torgue",
                       text: "THIS IS A TEST MESSAGE! SQUEEDLYBAMBLYFEEDLYMEEDLYMOWWWWWWWW!",
                       channel: "#general");
        }
    }
}

有人能告诉我我的错误吗？

我的控制台应用看起来像这样

SlackClient.cs

using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

namespace SlackProject1
{
    public class SlackCient
    {

        private readonly Uri _webhookUrl;
        private readonly HttpClient _httpClient = new HttpClient();

        public SlackCient(Uri webhookUrl)
        {
            _webhookUrl = webhookUrl;
        }

        public async Task<HttpResponseMessage> SendMessageAsync(string message,
            string channel = null, string username = null)
        {
            var payload = new
            {
                text = message,
                channel,
                username,
            };
            var serializedPayload = JsonConvert.SerializeObject(payload);
            var response = await _httpClient.PostAsync(_webhookUrl,
                new StringContent(serializedPayload, Encoding.UTF8, "application/json"));

            return response;
        }
    }
}

和Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SlackProject1
{
    class Program
    {
        static void Main(string[] args)
        {
            Task.WaitAll(IntegrateWithSlackAsync());
        }

        private static async Task IntegrateWithSlackAsync()
        {
            var webhookUrl = new Uri("https://hooks.slack.com/services/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");
            var slackClient = new SlackCient(webhookUrl);
            while (true)
            {
                Console.Write("Type a message: ");
                var message = Console.ReadLine();
                var response = await slackClient.SendMessageAsync(message);
                var isValid = response.IsSuccessStatusCode ? "valid" : "invalid";
                Console.WriteLine($"Received {isValid} response.");
            }
        }
    }
}
