如果发送了特定消息,如何运行代码(电报机器人)

telegram-bot bots c#

desmondische · 技术社区 · 5 年前

我正在创建一个简单的电报机器人,它根据地理位置发送天气信息。

我希望它能像这样工作:

聊天中的用户类型/天气
Bot表示地理位置是必需的,并且会出现请求位置的自定义键盘
用户按下按钮共享位置并获得结果(天气信息)

一切都很好,除了一件事-若用户手动发送他的位置,机器人会做出反应,并给出天气反馈。我想让它(天气信息代码)只在聊天中发送/weather时工作。我想检查前一条消息文本是否等于“/weather”,但找不到解决方案:/

C#代码:

private static void Bot_OnMessage(object sender, MessageEventArgs e)
    {
        var message = e.Message;

        if (message == null || message.Type != MessageType.Text) return;

        try
        {
            switch (message.Text)
            {
                case "/weather":
                    var requestLocationKeyboard = new ReplyKeyboardMarkup(new[]
                        {
                                new KeyboardButton("Share my location") {RequestLocation = true},
                            });

                    Bot.SendTextMessageAsync(
                       message.Chat.Id,
                       "To get the information about weather, you should share your current location.",
                       replyMarkup: requestLocationKeyboard);
                    break;



private static async void Bot_OnLocationReceived(object sender, MessageEventArgs e)
    {
        Thread.Sleep(1000);
        var message = e.Message;
        if (message == null || message.Type != MessageType.Location) return;

        var latitude = message.Location.Latitude;
        var longitude = message.Location.Longitude;

        latitude = (float)Math.Round(latitude, 3);
        longitude = (float)Math.Round(longitude, 3);

        Lat = latitude.ToString(CultureInfo.InvariantCulture);
        Lon = longitude.ToString(CultureInfo.InvariantCulture);

        await Bot.SendTextMessageAsync(
            message.Chat.Id,
            "_Processing Received Location..._",
            ParseMode.Markdown,
            replyMarkup: new ReplyKeyboardRemove());

        Console.WriteLine("{0};{1}", Lat, Lon);

        WeatherResponse weather = GetWeatherData();
        await Bot.SendTextMessageAsync(message.Chat.Id, "Your location: " + weather.List[0].Name + "\n" +
                                                        "Temperature: " + Convert.ToInt32(weather.List[0].Main.Temp) + " Â°C" +
                                                        "\n" + "Summary: " + weather.List[0].Weather[0].Description);
    }

添加类字段以存储最后一条消息

private string _lastMessage;

private static void Bot_OnMessage(object sender, MessageEventArgs e)
{
    var message = e.Message;

    if (message == null || message.Type != MessageType.Text) return;

    _lastMessage = message.Text; // <=============
    try
    {
        switch (message.Text)
    ...
}

在里面 Bot_OnLocationReceived :

if (_lastMessage  == "/weather") {
    //TODO: display weather info
} else {
    //TODO: display only geo location.
}
