Websocket 连接后立即断开连接（重复）

Question

我遵循了这个教程：https://github.com/jacobian/channels-example

然后我得到了标题中的错误，然后我克隆了上面的存储库并得到了同样的错误。

（如果您尝试克隆存储库进行测试，请记住更改 settings.py 中的数据库设置，迁移数据库，然后进入视图并将 import haikunator 更改为 from haikunator import Haikunator 并在 new_room 函数中将行 haikunator = Haikunator() 添加到函数的开头，以便它可以工作）

我正在使用 Python 2.7 和 Django 1.10。 '

感谢任何帮助，提前致谢。

我运行使用相同的 repo 解决了这个问题。对我来说问题是频道的版本。我相信在 1.10 版本之后（版本可能有误），您现在必须将消息发回 reply_channel。

message.reply_channel.send({'accept':True})

这不在他的代码中。可能是在更改频道之前写的。添加后将停止断开连接。请参阅此处的文档： Channels Documentation

看看下面最后一行函数：

def ws_connect(message):
# Extract the room from the message. This expects message.path to be of the
# form /chat/{label}/, and finds a Room if the message path is applicable,
# and if the Room exists. Otherwise, bails (meaning this is a some othersort
# of websocket). So, this is effectively a version of _get_object_or_404.
    try:
        prefix, label = message['path'].strip('/').split('/')
        #log.debug('prefix=%s label=%s', prefix, label)
        if prefix != 'chat':
            log.debug('invalid ws path=%s', message['path'])
            return
        room = Room.objects.get(label=label)
    except ValueError:
        log.debug('invalid ws path=%s', message['path'])
        return
    except Room.DoesNotExist:
        log.debug('ws room does not exist label=%s', label)
        return

    log.debug('chat connect room=%s client=%s:%s', 
        room.label, message['client'][0], message['client'][1])


    Group('chat-'+label, channel_layer=message.channel_layer).add(message.reply_channel)

    message.channel_session['room'] = room.label

    message.reply_channel.send({'accept':True})
