nginx将uri重写为文件

Question

I need nginx to open files by uri like:

http://example.com/en/foo/test-bar from /var/www/example.com/en_US/_foo_test_bar

or

http://example.com/en/foo2/test2-bar from /var/www/example.com/en_US/_foo2_test2_bar

replacing all symbols except letters/numbers to underline. How should look this location, may be better would be using redirect?

location /en/ {
rewrite ...
}

I don't know best practice for such mechanism in nginx and regexp. Thank you.

You can use rewrite to recursively change the symbols until they are all changed. Assuming that the real files are under en_US as your example shows:

location /en/ {
    rewrite ^/en/(.*)[^A-Za-z0-9_](.*)$ /en/$1_$2 last;
    rewrite ^/en/(.*)$ /en_US/$1 last;
}
location /en_US/ {
    root /path/to/real/files;
}

The first rewrite repeatedly matches until all of the symbols are consumed. The second rewrite prepares the URI to serve the real file.
