看ensure_future 的代码,会发现 ensure_future 内部在某些条件下会调用 create_task,综上所述: encure_future: 最高层的函数,推荐使用! create_task: 在确定参数是 coroutine 的情况下可以使用。 Task: 可能很多时候也可以工作,但真的没有使用的理由!
我使用ensure_future的主要动机一直是它是与循环成员create_task(讨论包含一些想法,例如添加asyncio.spawnasyncio.create_task)。 我还可以指出,在我看来,使用可以处理任何Awaitable的通用函数非常方便,而不是仅使用协程。 但是,Guido 的回答很明确:“从协程创建任务时,您应该使用适当命名的loop.create_task()” 协程什...
the model that I tend to have in my mind is that I create a coroutine object which is ready to run, then I deliver it to the event loop withmy_task = loop.create_task(my
将上面代码中的task = loop.create_task(asyncfunc1()) 改为 task = asyncio.ensure_future(asyncfunc1())会得到相同的结果,它的参数是协程对象或者futures,也可以传task对象,因为task是futures的子类,当传入的是一个协程对象时,返回一个task对象,传入一个futures的时候,直接返回futures对象,也就是说,在调用async...
