【问题描述】：

我尝试让我的 Django 项目使用 WebSockets 运行；在浏览器控制台中我收到错误

WebSocket connection to 'wss://www.xxx.com:8001/ws/asdf/1234/' failed:

settings.py：

CHANNEL_LAYERS = {
        "default": {
            "BACKEND": "channels_redis.core.RedisChannelLayer",
            "CONFIG": {
                "hosts": [("config('REDIS_SERVER_NAME')", 6379)],
            },
            "ROUTING": "myproject.routing.channel_routing",
        },
    }

asgi.py:

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings')
django.setup()
application = get_default_application()

nginx配置：

server{
        server_name <IP-adress> <xxx.xxx>;

        location = /favicon.ico { access_log off; log_not_found off; }
        location / {
                include proxy_params;
                proxy_pass http://unix:/home/ubuntu/myproject/myproject.sock;
        }
        location /ws/ {
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_redirect off;
                proxy_pass http://127.0.0.1:8001/;
        }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/xxx.xxx/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/xxx.xxx/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}

daphne.service：

该站点运行良好，当我在没有来自 certbot 的域 SSL 证书的情况下对其进行测试时，ws:// 正在运行。任何帮助表示赞赏...

【问题讨论】：

我也不知道如何调试或开始解决问题。 nginx 日志文件和控制台输出没有太大帮助......我应该采取什么方法？

【解决方案1】：

我想通了！我改变了我的文件如下。

nginx配置：

server{
        server_name mydomain.com www.mydomain.com
        location = /favicon.ico { access_log off; log_not_found off; }
        location / {
                include proxy_params;
                proxy_pass http://unix:/home/ubuntu/myproject/myproject.sock;
        }

        location /ws/ {
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_redirect off;
                proxy_pass http://unix:/tmp/daphne.sock;
        }
    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/mydomain.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/mydomain.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

daphne.service：
