Nginx通过正则表达式缓存特定位置

Question

我只想缓存特定位置的内容。但是当我尝试使用正则表达式时，它不是缓存。

proxy_cache_path /AINginxService/nginx-1.16.1/cache/ levels=1:2 keys_zone=one:10m max_size=8g inactive=5d use_temp_path=off;

proxy_cache one;    

    location ~* /v1/mydata/studies/[0-9.]+/series/[0-9.]+/instances/[0-9.]+/rendered {
        #rewrite http://([^/]+)/rendered break;
        proxy_cache_valid 200 120h;
        proxy_pass http://127.0.0.1:9000/v1/mydata;
        proxy_set_header Host $host;
        proxy_pass_request_headers on;
        proxy_http_version 1.1;
        proxy_set_header Origin "";
        proxy_connect_timeout 1d;
        proxy_send_timeout 1d;
        proxy_read_timeout 1d;
        send_timeout 1d;
    }

    # Rest api entry point
    location /v1/mydata {
        #proxy_cache_valid 200 120h;
        proxy_pass http://127.0.0.1:9000/v1/mydata;
        proxy_set_header Host $host;
        proxy_pass_request_headers on;
        proxy_http_version 1.1;
        proxy_set_header Origin "";
        proxy_connect_timeout 1d;
        proxy_send_timeout 1d;
        proxy_read_timeout 1d;
        send_timeout 1d;
    }
}

PS ：如果我取消注释/ v1 / mydata中的proxy_cache_valid，它将缓存所有内容。
注意：可能的网址格式

 1. /v1/mydata/studies/{study_id}/       # Not to cahce
 2. /v1/mydata/studies//series/{series_id}/      # Not to cache
 3. /v1/mydata/studies//series/{series_id}/instances/{instance_id}/    # Not to cahce
 4. /v1/mydata/studies//series/{series_id}/instances/{instance_id}/rendered     # Cache this
