        # 1. 认证中心 (IdentityServer4) 路由 - 专门处理并移除 'auth' 前缀
        # 匹配 /auth/ 开头的请求
        location ~ ^/auth/ {
            # rewrite 规则：
            # ^/auth(/.*)$  : 匹配以 /auth 开头，并捕获 / 后面的所有路径到 \$1
            # \$1            : 替换为 \$1，即只保留 /auth 后面的路径
            # break         : 停止处理当前的 rewrite 规则，然后处理 proxy_pass
            rewrite ^/auth(/.*)$ \$1 break;

            proxy_ssl_verify off;  # 关闭证书验证
        }

        # 1. 认证中心 (IdentityServer4) 路由
        # 匹配所有认证相关的路径
        location ~ ^/(connect|Account)/ {
            proxy_pass https://auth_server;
            proxy_ssl_verify off;  # 关闭证书验证
        }

        # 2. Sys API 路由
        location /api/sys/ {
            # 将 /api/sys/path -> http://sys_api/api/sys/path
            proxy_pass https://sys_api;             
            proxy_ssl_verify off;  # 关闭证书验证
        }

        # 3. Lmg API 路由
        location /api/lmg/ {
            # 将 /api/lmg/path -> http://lmg_api/api/lmg/path
            proxy_pass http://lmg_api; 
        }

        # 4. Lmg UI 路由
        # IMPORTANT: lmg-ui 的前端路由基础路径(base path)需要配置为 /lmg/
        location /lmg/ {
            # 将 /lmg/path -> http://lmg_ui/path
            proxy_pass http://lmg_ui/; 
        }
        
        # 5. Sys UI 和根路径路由
        # IMPORTANT: sys-ui 的前端路由基础路径(base path)需要配置为 /
        # 或者如果你想用 /sys/ 访问，则前端基础路径配 /sys/
        location / {
            # 根路径 / 直接访问 sys_ui
            # 将 /path -> http://sys_ui/path
            proxy_pass http://sys_ui;
        }

        # 6. OAuth 回调地址路由
        # 这个回调是给客户端(UI)的，这里我们假设它由 sys-ui 处理
        location = /Callback {
            # 将 /Callback -> http://sys_ui/Callback
            proxy_pass http://sys_ui;
        }
    }
