似乎Group和channel_session可以在多个消息会话和消费者中持续存在。渠道如何实现这一目标?
@channel_session_user_from_http
def ws_connect(message):
# Add them to the right group
message.channel_session['room'] = 'room name'
Group("chat-%s" % message.user.username[0]).add(message.reply_channel)
@channel_session_user
def ws_disconnect(message):
if 'room' in message.channel_session:
print('room====', message.channel_session['room'])
Group("chat-%s" % message.user.username[0]).discard(message.reply_channel)
我想设置一个长的现有对象,就像每个消费者都可以访问的全局对象一样。

您可以使用@channel_session
(或@channel_session_user
)装饰器来实现此目的。确保您的对象是可序列化的,然后将其添加到用户的频道会话中,如下所示:
@channel_session_user_from_http
def ws_connect(message):
message.session.myobject = {'test': True}
@channel_session_user
def ws_connect(message):
print(message.session.myobject) # should output {'test': True}
或者,只需使用您的数据库或redis来保存像Django中通常那样的东西:
@channel_session_user_from_http
def ws_connect(message):
redis_conn.set('my-persisted-key', "{'test': True}")
@channel_session_user
def ws_connect(message):
print(redis_conn.get('my-persisted-key')) # should output "{'test': True}"
