回复至：nginx 反代的sub_filter替换无效

[孙锡源]

location 匹配的原则是从长到短，所以你上面的配置文件中 app.591f9646.js 匹配到的是以下块：

location ~* .(gif|png|jpg|css|js|woff|woff2)$
{
    proxy_pass https://cmsstaticv2.ffquan.cn;
    proxy_set_header Host cmsstaticv2.ffquan.cn;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header REMOTE-HOST $remote_addr;
    expires 12h;
}

想对关键字替换的话就把替换相关的配置提升到全局作用域上
