tornado用多线程@run_on_executor报错There is no current event loop in thread

Question

from tornado.concurrent import run_on_executor

  @run_on_executor

  def Timing_send(self, cmd):

    while 1:

      self.sendMsg(cmd)

      time.sleep(1)

网上找了几个帖子都讲的不明确，如何在tornado里正确的使用多线程

Answer 1

你是不是在后台线程处理的，

试试这个

from tornado.platform.asyncio import AnyThreadEventLoopPolicy
asyncio.set_event_loop_policy(AnyThreadEventLoopPolicy())
