的WebSocket連接（反覆）後立即斷開

我跟着這個教程：https://github.com/jacobian/channels-example 的WebSocket連接（反覆）後立即斷開

我的稱號得到了錯誤，那麼我上面克隆庫，並得到了同樣的錯誤。

（如果你想克隆庫進行測試，記得要更改數據庫設置settings.py中，遷移數據庫，並進入意見和修改import haikunator到from haikunator import Haikunator，並在new_room功能添加行haikunator = Haikunator()到該函數的開頭，以便它能正常工作）

我使用Python 2.7的廣告Django 1.10。「

我遇到了同樣的回購這個問題。對我來說，問題是渠道的版本。我相信，在版本1.10之後（版本可能有錯誤），您現在必須將消息發送回reply_channel。

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

這不在他的代碼中。可能寫在頻道改變之前。一旦添加將停止斷開連接。查看文檔在這裏： Channels Documentation

採取在功能最後一行下面一起來看看：

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})

這個問題在Chrome中仍然存在（即使接受：真正的json被返回）... Safari和Firefox的工作。 –
