Question

我有这个将数据发送到频道的JavaScript代码

// Note that the path doesn't matter for routing; any WebSocket
// connection gets bumped over to WebSocket consumers
socket = new WebSocket("ws://" + window.location.host + "/chat/");
socket.onmessage = function(e) {
    alert(e.data);
}
socket.onopen = function() {
    socket.send({"test":"data"});
}
// Call onopen directly if socket is already open
if (socket.readyState == WebSocket.OPEN) socket.onopen();

我很好奇message我如何得到json {"test":"data"}

这是视图

# Connected to websocket.connect
@channel_session
def ws_connect(message, key):
    # Accept connection
    message.reply_channel.send({"accept": True})

您实现了连接回调，但未实现消息到达服务器端点时应发生的情况。添加添加消息接收功能：

def on_receive(message):
    print('test received: {}'.format(message.content['test']))

在routing.py注册该功能：

channel_routing = [
    route("websocket.connect", ws_connect),
    route("websocket.receive", on_receive),
]

您发送的JSON消息将存储在message.content中，这基本上只是一个python dict。
