使 Nginx 代理仅升级 Docker Compose 堆栈中的 SignalR WebSocket 连接

Question

有没有办法只升级 nginx.conf 文件中的 SignalR WebSocket 连接而不复制整个部分？

ASP.NET Core 在未升级时拒绝我的 SignalR 连接，但是我运行 API 那个 ASP.NET Core 项目不会'当请求具有 header "Connection: " 升级"".

时，不接受带正文的 POST 请求

我目前的解决方案只是复制 nginx.conf 文件中的 "location" 部分，如下所示。有没有更优雅的解决方案？

谢谢！

我的 nginx.conf 文件：

worker_processes 1;

events {
    worker_connections 1024;
}

http {
    server {
        listen 80;

        include /etc/nginx/mime.types;

        gzip on;
        gzip_min_length 1000;
        gzip_proxied expired no-cache no-store private auth;
        gzip_types text/plain text/css application/json application/javascript application/x-javascript text/xml application/xml application/xml+rss text/javascript;

        location / {
            proxy_pass http://ui:80;
            rewrite ^/(.*)$ / break;
        }

        location /shopvac/signalr {
            proxy_pass http://shopvac:80;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
            rewrite ^/shopvac/(.*)$ / break;
        }

        location /shopvac {
            proxy_pass http://shopvac:80;
            rewrite ^/shopvac/(.*)$ / break;
        }
    }
}

我的 docker-compose.yaml 文件：

version: "3"

networks:
  proxy:
  database:

volumes:
  database-data:

services:
  proxy:
    image: nginx:latest
    depends_on:
      - ui
      - shopvac
    volumes:
      - ./nginx.conf:/etc/nginx/nginx.conf
      - ./logs/nginx:/var/log/nginx
    ports:
      - "80:80"
      - "443:443"
    networks:
      - proxy
  database:
    image: postgres:latest
    volumes:
      - database-data:/var/lib/postgresql/data
    expose:
      - "5432"
    networks:
      - database
    environment:
      - POSTGRES_DB=home-system
      - POSTGRES_USER=home-system
  ui:
    build:
      context: ./ui
      dockerfile: Dockerfile
    expose:
      - "80"
    networks:
      - proxy
  shopvac:
    build:
      context: ./shopvac
      dockerfile: Dockerfile
    depends_on:
      - database
    volumes:
      - /app
    expose:
      - "8080"
    networks:
      - proxy
      - database

找到解决方案！

所以你可以编辑nginx.conf中的"proxy_set_header Connection"属性来传递必要的值。

现在nginx.conf的重要部分如下：

location /shopvac {
    proxy_pass http://shopvac:80;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $http_connection;
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
    rewrite ^/shopvac/(.*)$ / break;
}
