我正在開發一個基于 GAE 和 python 2.7.13 的應用程序。我想要做的是在處理程序中進行一堆異步 API 調用。類似的東西：class MakeRequests(webapp2.RequestHandler):   def post(self, *v, **kv):       *do an async api call#1*       *do an async api call#2*       *do an async api call#3*       *wait for response from all of above api requests*       *make response in a way like if call#1 failes, make it's expected*       *attributes in response as None, if call#2 succeeds add it's*       *attributes in response etc. This is just an example.*為此，我已經試過像圖書館asyncio，grequests，requests和simple-requests，他們不似乎是工作，因為無論他們是不兼容GAE或python 2.7.13。有人能幫我一下嗎？
