特定 nginx 块代码内的文本处理

Question

当脚本运行时，我需要转换保留在其中的以下文本块。那个部分

include conf.d/includes-optional/cpanel-proxy.conf;
proxy_pass $scheme://$CPANEL_APACHE_PROXY_REQ_IP:$CPANEL_APACHE_PROXY_REQ_PORT;

可能会改变，所以我需要处理块内的任何内容

location / {
    
}

代码：

location / {
    include conf.d/includes-optional/cpanel-proxy.conf;
    proxy_pass $scheme://$CPANEL_APACHE_PROXY_REQ_IP:$CPANEL_APACHE_PROXY_REQ_PORT;
}

进入

location / {
    limit_req zone=foo burst=300 nodelay;
    limit_conn addr 1;
    limit_rate 200k;
    include conf.d/includes-optional/cpanel-proxy.conf;
    proxy_pass $scheme://$CPANEL_APACHE_PROXY_REQ_IP:$CPANEL_APACHE_PROXY_REQ_PORT;
}
    
limit_req_status 429;
limit_conn_status 429;
    
error_page 429 /429.html;
location = /429.html {
    root /usr/share/nginx/html;
    internal;
}
