Question

nginx location 配置问题

location ~* \.(gif|jpg|png|jpeg)$ {
root /Users/yangyang/Library/tomcat8_1/webapps/wulianwang/; #站点根目录
set $image_root /Users/yangyang/Library/tomcat8_1/webapps/wulianwang/upload; #图片目录
set $thumbnail_root /Users/yangyang/Library/tomcat8_1/webapps/wulianwang/upload/thumbnail; #缩略图存放目录
rewrite_by_lua_file lua/thumbnail.lua;
break;
}
这点我想实现访问的url根上了参数例如 http://127.0.0.1/img/_8c60aeff-d95a-4a7d-bbfc-ad1444e210f4.jpg?a=3这种情况location才匹配上，这个怎么写呢 只要以gif|jpg|png|jpeg结尾而且带有参数的才进入location中

location ~* \.(gif|jpg|png|jpeg)$ {
    if ($query_string = "") {
        break;
