我还记得Django中对象的实例吗

Question

我使用django-channels和aiortc，我想将server to peer连接创建为WebRTC。

在我的情况下，如果客户端发送new-peer操作，则服务器发送报价。

在客户收到报价后，客户将答案作为new-answer动作发送。

但服务器记不住peer，所以记不起setRemoteDescription。

当然，我知道服务器不记得了，但我该如何处理服务器需要记住像我这样的实例的情况？

我还查找了会话变量，但似乎只有简单的值​​可以存储，而且它似乎与实例无关。

请提供与此相关的有用文档或解决方案。

消费者接收方式：

async def receive(self, text_data):
receive_dict = json.loads(text_data)
message = receive_dict['message']
action = receive_dict['action']
if (action == 'new-peer'):
# Create Offer
peer, offer = await create_offer()
receive_dict['message']['sdp'] = offer
receive_dict['action'] = 'new-offer'
receive_dict['message']['receiver_channel_name'] = self.channel_name
await self.channel_layer.send(
self.channel_name,
{
'type': 'send.sdp',
'receive_dict': receive_dict
}
)
return None  
elif (action == 'new-answer'):
await peer.setRemoteDescription(receive_dict['message']['sdp'])
receiver_channel_name = receive_dict['message']['receiver_channel_name']
receive_dict['message']['receiver_channel_name'] = self.channel_name
await self.channel_layer.send(
receiver_channel_name,
{
'type': 'send.sdp',
'receive_dict': receive_dict, 
}
)
return None
else:
raise ValueError('Unexpected action value');

create_offer函数：

async def create_offer():
pc = RTCPeerConnection(RTCConfiguration(iceServers))
rtsp_video = MediaPlayer(rtsp_test_url)
relay = MediaRelay()
pc.addTrack(relay.subscribe(rtsp_video.video))
@pc.on("connectionstatechange")
async def on_connectionstatechange():
print("Connection state is %s", pc.connectionState)
if pc.connectionState == "failed":
await pc.close()
await pc.setLocalDescription(await pc.createOffer())
return pc, object_to_string(pc.localDescription)

已解决：django会话支持将实例保存到会话中。
