aiohttp - 如何知道我请求客户端何时断开连接？

Question

    async def index(self,request):
        content = open(os.path.join(self.ROOT, "index.html"), encoding="utf8").read()
        while(True):
            time.sleep(1)
            #if request["status"] == "disconnected":
            #   break

如何知道 aiohttp 请求中客户端何时断开连接？

Answer 1

在aiohttp中，可以通过监听request.transport对象来检查客户端是否断线。 request.transport 对象表示与当前请求关联的传输层（TCP、SSL 等）。

from aiohttp import web

class YourView(web.View):
    async def index(self, request):
        content = open(os.path.join(self.ROOT, "index.html"), encoding="utf8").read()

        while True:
            await asyncio.sleep(1)

            # Check if the transport is closed/disconnected
            if request.transport is None or request.transport.is_closing():
                break

            # Your other logic here...

        # Any cleanup or finalization logic after the loop
        ...

        return web.Response(text="Done")
