nginx配置长连接、短连接、WebSocket的实现步骤

http {
    # 全局配置
    keepalive_timeout 65; # 设置超时时间，65秒后关闭连接（默认为75秒）
    keepalive_requests 100; # 在关闭连接之前，允许的最大请求数量

    server {
        listen 80;
        server_name example.com;

        location / {
            proxy_pass http://backend_server;
            proxy_http_version 1.1;
            proxy_set_header Connection keep-alive;
        }
    }
}

http {
    server {
        listen 80;
        server_name example.com;

        location / {
            proxy_pass http://backend_server;
            proxy_http_version 1.1;
            proxy_set_header Connection close; # 禁用长连接
        }
    }
}

nginx

http {
    server {
        listen 80;
        server_name example.com;

        location /ws/ {
            proxy_pass http://backend_server;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "Upgrade";
            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-Proto $scheme;

            # 可选的 WebSocket 相关设置
            proxy_read_timeout 300s;
            proxy_send_timeout 300s;
        }
    }
