【问题描述】：

您好，我遇到了一个错误。

在来这里之前，我尝试了很多不同的方式，并查看了之前在这里打开的主题。但无论我做什么，它总是给我错误。

我试过daphne和uvicorn但是结果是一样的，在本地环境下打开但是在服务器上不工作，报这个错误：

我的代码：

Js 代码：

<script>

function connectSocket() 
var ws = new WebSocket('ws://' + window.location.host + '/ws/notification/request.user.id/')

ws.onopen = function(event)
console.log('opened', event);


//If there is a long onmessage codes here, I removed the code, no syntax error

ws.onclose = function(e) 
console.error('Chat socket closed unexpectedly; reconnecting');
setTimeout(connectSocket, 1000);
;

ws.onerror = function(event)
console.log('error', event);


// window.setInterval(function()
// loadNotifications();
// , 1000);

connectSocket();
</script>

Settings.py
[/JSR]
[CODE]
CHANNEL_LAYERS = 
"default": 
'BACKEND': 'channels_redis.core.RedisChannelLayer',
'CONFIG': 
"hosts": [("redis", 6379)],
,
,




ASGI_APPLICATION = "thesite.routing.application"

asgi

import os
import django
from channels.routing import get_default_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'thesite.settings')

django.setup()

application = get_default_application()

nginx：

server 
listen 80;
server_name **.net www.**.net; #** = site name
root /home/ftpuser/project; 

location /static/ 

alias /home/ftpuser/project/site/static/;


location /media/ 


location / 

proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;

proxy_pass http://unix:/home/ftpuser/project/thesite.sock;



location /ws/ 

proxy_pass http://0.0.0.0:9001;

proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";

proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;

【参考方案1】：

哦不=（这个错误是语法错误

proxy_set_header Connection "upgrade";

改为：

proxy_set_header Connection “upgrade”;

但现在我给出 404 错误

failed: Error during WebSocket handshake: Unexpected response code: 404

我猜是什么原因 处理 ASGI_APPLICATION 参数失败
