django_channels

websocket框架

用户登录

原理

1. zadd asgi:group:<room_name> 保存了一个room监听的websocket的客户端

2. zadd asgispecific.<clientid>! 保存了每个websocket客户端应该收到的消息

手动添加到某个频道

from channels_layers import get_channel_layer
get_channel_layer().group_add(<groupname>, channel_name)

把用户加入全体用户监听频道

class Consumer:
    def connect:
        self.channel_layer.group_add("all_user", self.channel_name)

    def disconnect:
        self.channel_layer.group_discard("all_user", self.channel_name)
