我正在尝试在使用 aiogram 的电报机器人中发送加密货币的价格警报。我遇到的问题是我不确定如何将函数作为后台非阻塞线程启动,然后继续启动调度程序。我知道如何使用标准同步电报机器人来做到这一点,但我对我应该用 aiogram 做什么感到困惑。我读到我可以使用 dp.loop.create_task
here 但这会引发错误 Nonetype has no attribute create_task
。这是我尝试使用以下代码执行这些线程的代码:
print('Starting watchlist process, this needs to run as a non blocking daemon...')
dp.loop.create_task(wl.start_process())
print('Starting broadcaster, this needs to run as a non blocking daemon ... ')
dp.loop.create_task(broadcaster())
print('Starting the bot ...')
executor.start_polling(dp, skip_updates=True)
我只需要 wl.start_process
和 broadcaster
函数在后台运行。我该如何实现?
这是start_process
:
async def start_process(self):
"""
Start the watchlist process.
:return:
"""
threading.Thread(target=self.do_schedule).start()
await self.loop_check_watchlist()
这是broadcaster
:
async def broadcaster():
count = 0
while True:
uid_alerts = que.__next__()
if uid_alerts:
for i in uid_alerts:
uid = i[0]
alert = i[1]
try:
if await send_message(uid, alert):
count += 1
await asyncio.sleep(.05) # 20 messages per second (Limit: 30 messages per second)
finally:
log.info(f"{count} messages successful sent.")
答案 0 :(得分:1)
我为您创建了以下工作示例,它演示了如何在机器人启动时创建后台任务以及如何在用户命令的帮助下创建后台任务。
