如何接收电报机器人的回调

Question

public class TelegramBotController : ControllerBase
{
    private readonly TelegramBotClient _botClient;
    private const string BotToken = "MyToken";

    public TelegramBotController()
    {
        _botClient = new TelegramBotClient(BotToken);
    }

    [HttpPost]
    public async Task<IActionResult> Post([FromBody] Telegram.Bot.Types.Update update)
    {
        await _botClient.SendTextMessageAsync(chatId: myUserId, "Hello guys");

        return Ok();
    }
}

这是我从机器人电报接收回调的代码，我还使用邮递员成功调用

setwebhook

。

当我向电报机器人发送文本时，它没有收到回调。

我正在关注这个视频：

我尝试搜索并使用 chatgpt 寻求帮助，但它不起作用。我的期望是接收来自电报的回调并将其发送回消息

要接收回电，您需要设置一个

webhook

URL，以便 Telegram 在状态发生变化时给您回电。

参考以下代码：

public class TelegramBotController : ControllerBase
{
    private readonly TelegramBotClient _botClient;
    private const string BotToken = "YourBotToken";

    public TelegramBotController()
    {
        _botClient = new TelegramBotClient(BotToken);
    }

    [HttpPost("/webhook")] // Set up your webhook URL here
    public async Task<IActionResult> Post([FromBody] Update update)
    {
        if (update == null)
        {
            return BadRequest();
        }

        
        if (update.Message != null)
        {
            
            await HandleIncomingMessage(update.Message); // For incoming messages
        }
        else if (update.CallbackQuery != null)
        {
            
            await HandleIncomingCallbackQuery(update.CallbackQuery); // For incoming callback queries
        }

        return Ok();
    }

    private async Task HandleIncomingMessage(Message message)
    {
        
        await _botClient.SendTextMessageAsync(chatId: message.Chat.Id, text: "Hello guys"); // Your message handling logic here
    }

    private async Task HandleIncomingCallbackQuery(CallbackQuery callbackQuery)
    {
        Console.WriteLine("Call back query Incomming");
    }
}
