我是asyncio和aiohttp新手。我目前得到这个错误，不知道为什么我收到InvalidStateError我asyncio未来RuntimeError为我的会议：带有asyncio futures和RuntimeError的InvalidStateError与aiohttp时使用期货回调

我所试图做的是POST到端点，然后使用相同的事件POST编辑发布到另一个端点。这将是跑了作为另一async方法作为callback

这里是我的代码：

async def async_post_event(self, event, session):

async with session.post(self.endpoint, data=event) as resp:

event["tracer"]["post"]["timestamp"] = time.time() * 1000.0

event["tracer"]["post"]["statusCode"] = await resp.status

return event

async def send_oracle(self, event, session):

async with session.post(self.oracle, data=event) as resp:

return event["event"]["event_header"]["event_id"], await resp.status

async def async_post_events(self, events):

tasks = []

conn = aiohttp.TCPConnector(verify_ssl=self.secure)

async with aiohttp.ClientSession(connector=conn) as session:

for event in events:

task = asyncio.ensure_future(self.async_post_event(event, session))

task.add_done_callback(self.send_oracle, task.result(), session)

tasks.append(task)

return await asyncio.gather(*tasks)

def post(self):

event_loop = asyncio.get_event_loop()

try:

events = [self.gen_random_event() for i in range(self.num_post)]

results = event_loop.run_until_complete(self.async_post_events(events))

print(results)

finally:

event_loop.close()
