nginx做代理转发前端请求到后端的代码示例

server {
        listen 80;  # 监听端口

        server_name your-domain.com;  # 服务器域名或IP

        location /api {
            proxy_pass http://backend-server:8080;  # 代理转发地址
            proxy_set_header Host $host;  # 转发头部，保留原始主机名
            proxy_set_header X-Real-IP $remote_addr;  # 转发客户端真实IP
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;  # 转发原始 IP 地址
            proxy_set_header X-Forwarded-Proto $scheme;  # 转发协议（HTTP/HTTPS）
        }

        location / {
            # 处理其它请求（如静态文件等）
            root /var/www/html;  # 指定根文件夹
            index index.html index.htm;
        }
    }

server {
    listen 443 ssl;  # 监听 HTTPS
    server_name your-domain.com;

    ssl_certificate /etc/ssl/certs/your-certificate.crt;  # SSL 证书路径
    ssl_certificate_key /etc/ssl/private/your-private-key.key;  # SSL 私钥路径

    location /api {
        proxy_pass http://backend;  # 代理转发地址
        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;
    }
}

http {
    access_log /var/log/nginx/access.log;  # 访问日志路径
    error_log /var/log/nginx/error.log;    # 错误日志路径
}
