通过通道设置 Django 会话变量 (http_session)

Question

根据 Django 频道文档，

    You get access to a user’s normal Django session using the http_session 
    decorator - that gives you a message.http_session attribute that behaves 
    just like request.session. You can go one further and use 
    http_session_user which will provide a message.user attribute as well as 
    the session attribute.

无论如何我可以像这样设置会话变量吗？
我确实尝试过，但我收到一条错误消息，提示 NoneType is not iterable。

if 'username' not in message.http_session:
    message.http_session['username'] = 'temp'

换句话说，message.http_session 返回一个 NoneType。我尝试过使用装饰器 @http_session 和 @channel_session_user_from_http，但它们也没有帮助。

你只是设置了变量。

foo = '酒吧'

并且它在整个会话中持续存在
