我在 django 上使用 WebSockets 通道时遇到此错误生产：
WebSocket connection to 'wss://domain.me/ws/orders/confirm_all/' failed: Error during WebSocket handshake: Unexpected response code: 404
而在 localhost 上没有问题（使用 runserver 命令）
路由.py：
from django.conf.urls import url
from channels.routing import ProtocolTypeRouter, URLRouter
from channels.auth import AuthMiddlewareStack
from management.consumers import ConfirmAllOrdersConsumer
application = ProtocolTypeRouter({
'websocket': AuthMiddlewareStack(
URLRouter([
url(r'ws/orders/confirm_all/$', ConfirmAllOrdersConsumer),
])
),
})
js：
const ws_scheme = window.location.protocol === "https:" ? "wss" : "ws";
const ordersSocket = new WebSocket(
ws_scheme + '://'
+ window.location.host
+ '/ws/orders/confirm_all/'
);
消费者.py：
import json
from channels.generic.websocket import WebsocketConsumer
from orders.models import Orders
from time import sleep
class ConfirmAllOrdersConsumer(WebsocketConsumer):
def connect(self):
self.accept()
def disconnect(self, code):
self.disconnect(code)
def receive(self, text_data=None, bytes_data=None):
text_data_json = json.loads(text_data)
action = text_data_json['action']
if action == 'confirm_all':
revision_orders = Orders.objects.filter(status__exact='revision')
for idx, order in enumerate(revision_orders):
print(idx)
order.status = 'confirmed'
order.save()
sleep(0.33)
self.send(json.dumps({
'total_orders': revision_orders.count(),
'new_val': idx + 1
}))
它在 localhost 上通过 http/ws 工作，但在生产上通过 https/wss 不工作
我猜它来自 apache 配置，而不是脚本代码，所以这是我的 apache2 配置：
Apache2website.conf
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.

有什么想法吗？谢谢。
