官方範例:
from tornado.concurrent import Future
def async_fetch_future(url):
http_client = AsyncHTTPClient()
my_future = Future()
fetch_future = http_client.fetch(url)
fetch_future.add_done_callback(
lambda f: my_future.set_result(f.result()))
return my_future
什麼協程,非同步迷迷糊糊的!
完全不懂my_future = Future()為什麼要產生個Future物件,最後又回傳它！ ！已經痛苦了幾天了！ ！大神來解救下我吧
