# ============================================================
# Nginx 站点配置 —— api.trivoo.online 反向代理到 New API
#
# 目标路径：/etc/nginx/sites-available/api.trivoo.online
# 启用：ln -s /etc/nginx/sites-available/api.trivoo.online \
#            /etc/nginx/sites-enabled/
#       nginx -t && systemctl reload nginx
#
# 先以 HTTP 建站跑通，再执行 sudo certbot --nginx
# certbot 会自动把本文件改写成含 443 + 跳转的版本
