node.js - 电报机器人嵌套上一个按钮，node.js

如何从第3级节点返回到第2级节点？我的问题是Back名称，因为相同，
这是我的代码：

    bot.onText(/\/start/, function onLoveText(msg) {
      const opts = {
        reply_to_message_id: msg.message_id,
        reply_markup: JSON.stringify({
          keyboard: StartKeyboard,
          resize_keyboard:true,
          one_time_keyboard: true
        })
      };
      bot.sendMessage(msg.chat.id, 'Hello', opts);
    });
 bot.onText(/\Back/, function onLoveText(msg) {
      const opts = {
        reply_to_message_id: msg.message_id,
        reply_markup: JSON.stringify({
          keyboard: StartKeyboard,
          resize_keyboard:true,
          one_time_keyboard: true
        })
      };
      bot.sendMessage(msg.chat.id, 'Hello', opts);
    });
 bot.onText(/\Back/, function onLoveText(msg) {  //  I Can't Use Backkk
      const opts = {
        reply_to_message_id: msg.message_id,
        reply_markup: JSON.stringify({
          keyboard: BackKeyboard,
          resize_keyboard:true,
          one_time_keyboard: true
        })
      };
      bot.sendMessage(msg.chat.id, 'Hello', opts);
    });

最佳答案

您可能应该做的就是保存状态，该用户当前正在使用其唯一ID。

我没有为电报机器人使用nodejs的经验，因此以下代码是伪代码。

userStateMap = {};

switch ($chat.text)
{
    case "/start":
          sendWelcomeMessage($chat);
          userStateMap[$chat.id] = 0; // save the state
          break;
    case "1":
          $chat.text = "you clicked 1";
          $chat.reply_markup = getCustomKeyboard();
          return sendMessage($chat);
          userStateMap[$chat.id] = 1; // save the state
          break;
    case "about":
          $chat.text = "you clicked about";
          $chat.reply_markup = getCustomKeyboard();
          return sendMessage($chat);
          userStateMap[$chat.id] = 4; // save the state
          break;
    case "2":
          $chat.text = "you clicked 2";
          $chat.reply_markup = getCustomKeyboard2();
          return sendMessage($chat);
          userStateMap[$chat.id] = 2; // save the state
          break;
    case "previous":
          $chat.text = "you clicked previous";
          $chat.reply_markup = getCustomKeyboard(userStateMap[$chat.id]); // use the saved state
          return sendMessage($chat);
          break;
    case "3":
          $chat.text = "you clicked 3";
          $chat.reply_markup = getCustomKeyboard3();
          return sendMessage($chat);
          userStateMap[$chat.id] = 3; // save the state
          break;
}

//customize getCustomKeyboard to receive the state and use it to calculate the next keyboard

因此，您将在每次请求后更新状态，对于previous之类的请求，您将根据上次保存的状态来计算所需的键盘。
