# HTTP强制跳转HTTPS（同时处理www和非www）
server {
    listen 80;
    server_name emolo.cn www.emolo.cn;
    return 301 https://emolo.cn$request_uri; # 统一跳转到无www的HTTPS
}

# HTTPS www跳转非www（需独立server块）
server {
    listen 443 ssl;
    server_name www.emolo.cn;  # 专门处理www的HTTPS请求
    
    ssl_certificate /cart/emolo.cn_nginx/emolo.cn_bundle.crt;
