服务器不响应机器人请求

如何解决服务器不响应机器人请求

我创建了一个服务器并决定向其中添加一个机器人。首先我加了一个类

public static class AppSettings
    {
        public static string Url { get; set; } = @"https://47bc6f8ba722.ngrok.io/{0}";
        public static string Name { get; set; } = "Hop_hipBot";
        public static string Key { get; set; } = "1549046386:AAHJtCMVaCT-8O3D_P8VLsfq6EKAr4P9JfSU";
    }

然后我创建了一个命令和一个机器人。

public class Bot
    {
        private static TelegramBotClient botClient;
        private static List<Command> commandsList;

        public static IReadOnlyList<Command> Commands => commandsList.AsReadOnly();

        public static async Task<TelegramBotClient> GetBotClientAsync()
        {
            if (botClient != null)
            {
                return botClient;
            }

            commandsList = new List<Command>();
            commandsList.Add(new StartCommand());
            //TODO: Add more commands

            botClient = new TelegramBotClient(AppSettings.Key);
            string hook = string.Format(AppSettings.Url,@"api/message/update");
            await botClient.SetWebhookAsync(hook);
            return botClient;
        }
    }

    public class StartCommand : Command
        {
            public override string Name => @"/start";
    
            public override bool Contains(Message message)
             {
                 if (message.Type != Telegram.Bot.Types.Enums.MessageType.Text)
                     return false;
            
                 return message.Text.Contains(Name);
            }
    
            public override async Task Execute(Message message,TelegramBotClient botClient)
            {
                var chatId = message.Chat.Id;
                await botClient.SendTextMessageAsync(chatId,"Hello I'm ASP.NET Core Bot");
            }
        }

然后我将所有东西都与控制器相连，并在 Startup.cs 的 Bot.GetBotClientAsync().Wait(); 中添加 Configure()

    [Route("api/message/update")]
        public class MessageController : ControllerBase
        {
            // GET api/values
            [HttpGet]
            public string Get()
            {
                return "Method GET unuvalable";
            }
    
            [HttpPost]
            public async Task<OkResult> Post([FromBody] Update update)
            {
                if (update == null) return Ok();
                var commands = Bot.Commands;
                var message = update.Message;
                var botClient = await Bot.GetBotClientAsync();
                foreach (var command in commands)
                {
                    if (command.Contains(message))
                    {
                        await command.Execute(message,botClient);
                        break;
                    }
                }
                return Ok();
            }
        }

我在端口 44339 上启动服务器，并在 ngrox.exe http 44339 的帮助下为本地主机创建一个 URL，然后我开始一切。应用程序有效，沿 api/message/update 路由的 get 请求也有效，来自机器人的消息（我在 ngrok 检查上看到它），但服务器不响应它们。这与什么有关？
