Nginx子目錄設定中文路徑問題，子路徑映射配置必須爲root加通配符子路徑指定，不能用變量拼接跳轉

只能用
loacation ~ ^/down/(.)${
root "D:/downloadfile;"
set $file_url $1;
if ($query_string ~


^(.)action=down\b|download\b(.)$ ){
add_header Content-Disposition "attachment; filename=$1";
}
}
charset utf-8;

不能直接用
set $file_url $1;
if ($query_string ~ ^(.)action=down\b|download\b(.*)$ ){
add_header Content-Disposition "attachment; filename=$1";
}
