pip install python-telegram-bot

from telegram import Update
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters, CallbackContext
 
# 定义命令处理函数
def start(update: Update, context: CallbackContext) -> None:
    update.message.reply_text("你好！我是你的 Telegram Bot。发送 /help 获取帮助信息。")
 
def help_command(update: Update, context: CallbackContext) -> None:
    update.message.reply_text("以下是我可以执行的命令：\n/start - 启动 Bot\n/help - 获取帮助")
 
# 处理用户发送的文本消息
def echo(update: Update, context: CallbackContext) -> None:
    update.message.reply_text(f"你发送了：{update.message.text}")
 
def main():
    # 替换为你的 API Token
    TOKEN = "123456789:ABCDEF1234567890abcdef1234567890ABCDEF"
    updater = Updater(TOKEN)
 
    # 注册命令和消息处理器
    dispatcher = updater.dispatcher
    dispatcher.add_handler(CommandHandler("start", start))
    dispatcher.add_handler(CommandHandler("help", help_command))
    dispatcher.add_handler(MessageHandler(Filters.text & ~Filters.command, echo))
 
    # 启动 Bot
    updater.start_polling()
    updater.idle()
 
if __name__ == '__main__':
    main()

from datetime import datetime
 
def time_command(update: Update, context: CallbackContext) -> None:
    now = datetime.now().strftime('%Y-%m-%d %H:%M:%S')
    update.message.reply_text(f"当前时间是：{now}")

dispatcher.add_handler(CommandHandler("time", time_command))

def handle_photo(update: Update, context: CallbackContext) -> None:
    file = update.message.photo[-1].get_file()
    file.download("user_photo.jpg")
    update.message.reply_text("图片已接收并保存为 user_photo.jpg")
 
dispatcher.add_handler(MessageHandler(Filters.photo, handle_photo))
