如何基于aiogram 3.10在频道中发送模糊付费媒体？

问题 #

需要在Telegram频道发送带有模糊（剧透）效果的付费媒体，当前代码未实现该效果。

原代码 #

import asyncio
import logging
from aiogram import Bot, Dispatcher
from aiogram.filters import CommandStart
from aiogram.types import Message, InputPaidMediaPhoto

TOKEN = "qqqqqqqqqqqqqqqqqqqqqqqqqqqqqq"
PHOTO_URL = 'https://i.imgur.com/i2CvF2q.jpeg' 

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

bot = Bot(token=TOKEN)
dp = Dispatcher()

@dp.message(CommandStart())
async def command_start(message: Message):
    await message.answer_paid_media(star_count=500, media=[InputPaidMediaPhoto(media=PHOTO_URL)])

async def main():
    await dp.start_polling(bot)

if __name__ == '__main__':
    asyncio.run(main())

解决方案 #

要实现模糊效果，需利用InputPaidMediaPhoto的has_spoiler参数，同时调整发送逻辑以指向目标频道：

修改后的代码 #

import asyncio
import logging
from aiogram import Bot, Dispatcher
from aiogram.filters import CommandStart
from aiogram.types import Message, InputPaidMediaPhoto

TOKEN = "你的机器人令牌"
CHANNEL_ID = "-100XXXXXXXXXX"  # 替换为实际频道ID
PHOTO_URL = 'https://i.imgur.com/i2CvF2q.jpeg' 

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

bot = Bot(token=TOKEN)
dp = Dispatcher()

@dp.message(CommandStart())
async def command_start(message: Message):
    # 向指定频道发送带模糊效果的付费媒体
    await bot.send_paid_media(
        chat_id=CHANNEL_ID,
        star_count=500,
        media=[InputPaidMediaPhoto(media=PHOTO_URL, has_spoiler=True)]
    )
    await message.answer("已完成频道付费媒体发送")

async def main():
    await dp.start_polling(bot)

if __name__ == '__main__':
    asyncio.run(main())

关键说明 #

• 模糊效果开启：给InputPaidMediaPhoto添加has_spoiler=True参数，媒体会默认模糊显示，用户点击后才会清晰展示。
• 频道发送逻辑：使用bot.send_paid_media并指定chat_id为频道ID（格式为-100开头的数字ID），而非回复私聊消息的message.answer_paid_media。
• 权限准备：确保机器人是目标频道的管理员，拥有发布消息的权限。
