Question

我正在尝试在我的django应用程序中在用户级别设置websocket连接以接收通知。 prod是https所以需要使用wss。

这是js：

$( document ).ready(function() {

socket = new WebSocket("wss://" + window.location.host + "/user_id/");
var $notifications = $('.notifications');
var $notificationList = $('.dropdown-menu.notification-list');

$notifications.click(function(){
    $(this).removeClass('newNotification')
});

socket.onmessage = function(e) {

// notification stuff

// Call onopen directly if socket is already open
if (socket.readyState == WebSocket.OPEN) socket.onopen();

}

我在settings.py中实现了django-channels，如下所示：

CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "asgi_redis.RedisChannelLayer",
        "CONFIG": {
            "hosts":[ENV_STR("REDIS_URL")]
        },
        "ROUTING": "project.routing.channel_routing",
     },
}

routing.py

from channels.routing import route
from community.consumers import ws_add, ws_disconnect

channel_routing = [
    route("websocket.connect", ws_add),
    route("websocket.disconnect", ws_disconnect),
]

在当地，这握手就好了。

[2017/04/16 16:37:26] WebSocket CONNECT /user_id/ [127.0.0.1:60153]

但是，现在应用程序已部署到Heroku，/ _user_id / endpoint返回404，当它应该是有效端点时，我得到ERR_DISALLOWED_URL_SCHEME：

WebSocket connection to 'wss://mydomain.com/user_id/' failed: Error during WebSocket handshake: Unexpected response code: 404.

由于我正在继续研究，似乎这个服务器配置实际上不能支持prod中的websockets。当前Procfile：

web: gunicorn project.wsgi:application --log-file -
worker: python manage.py runworker -v2

我花了几个小时看着将应用程序转换为asgi并使用Daphne，虽然因为项目是python 2.7，这是一个很难转换（更不用说似乎需要不同的静态文件实现）

部署Django Channels应用程序后，在与用户端点进行WebSocket握手期间出错
