Nginx的sub_filter和反向代理不起作用

Question

我正在尝试反向代理cPanel的WHM API，目前我可以调用它并获得会话链接。问题是我想在输出之前更改链接

我在服务器块中有这个

location / {
         proxy_set_header Accept-Encoding "";
         access_log /var/log/test.log upstream_logging;
         proxy_pass_header Authorization;
         proxy_pass https://$upstream;
         proxy_set_header Host old.domain:2087;
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_http_version 1.1;
         proxy_set_header Connection "";
         proxy_buffering off;
         client_max_body_size 0;
         proxy_read_timeout 10000s;
         proxy_cookie_domain old.domain new.domain;
         proxy_redirect off;
         sub_filter_types plain/text;
         sub_filter old.domain new.domain;
         sub_filter_once off;
}

但是，当我调用API时，不会发生替换。
