python电报机器人ForceReply回调

问题描述

我目前正在使用 python-telegram-bot 开发电报机器人。我希望能够收到回复 ForceReply 的消息。预期的流程是这样的：

1. 用户发送 /start 命令
   
2. Bot 发送一条包含一些信息的消息。该消息与 ForceReply 相关联
   
3. 用户回复消息
4. 处理和操作消息。

我怎样才能达到预期的效果？谢谢

initial_message = "Hi... Please reply to this message to proceed to the next step..."

def start (update: Update,context: CallbackContext):
    chat_id = update.message.chat_id
    print(update.message.from_user.username)
    context.bot.send_message(chat_id=chat_id,text=initial_message,reply_markup=ForceReply())

解决方法

为了能够处理 ForceReply()，您必须实现一个 ConversationHandler。一旦用户回复ForceReply，使用ConversationHandler，您就可以处理他/她的回复。原来是这样的：

END = ConversationHandler.END
NEXTSTEP = range (1)

initial_message = "Hi... Please reply to this message to proceed to the next step..."
def start (update,context):
    chat_id = update.message.chat_id
    print(update.message.from_user.username)
    context.bot.send_message(chat_id=chat_id,text=initial_message,reply_markup=ForceReply())

    return NEXTSTEP

def nextstep (update,context):

    chat_id = update.message.chat_id
    ##user reply will be assigned to replied variable below
    replied = update.message.text
    print(replied)

    return END

def main():
    ##handler start
    start_handler = ConversationHandler(
        entry_points = [CommandHandler('start',start)],states = {
            NEXTSTEP: [MessageHandler(Filters.text & ~Filters.command,nextstep)]},fallbacks = [CommandHandler('cancel',callback = functions.cancel)])
    dp.add_handler(start_handler)
