我正在使用django-channelsand aiortc，我想将server to peer连接创建为WebRTC.
就我而言，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操作发送。
但是服务器不记得peer了，所以不能setRemoteDescription。
当然我知道服务器不记得了，但是我该如何处理服务器需要记住像我这样的实例的情况呢？
我也找了session变量，但是好像只能存储简单的值，和实例好像没什么关系。
请提供与此相关的有用文档或解决方案。
consumer.receive 方法：
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)
