Hello, would anyone know how to do this regular expression in .htaccess?

I need to leave the friendly URL pattern in this format:

http://dominio.com.br/usuario/joao.json
http://dominio.com.br/usuario/adriano.json
http://dominio.com.br/usuario/henrique.json

To return the following file in a directory schema configured this way:

/usuario/j/o/a/o/data.json
/usuario/a/d/r/i/a/n/o/data.json
/usuario/h/e/n/r/i/q/u/e/data.json

Knowing that the user can vary in size, being able to have more than 10 characters, how to create a regular expression with undefined number of parameters?

It has been commented that there should be a better way to organize folders.

This would be the solution. It is assumed that user names are [a-z] .

.htaccess

RewriteEngine on

# URL:                  Reescrita:
# usuario/ab/c/d.json   usuario/a/b/c/d.json
# usuario/abc/d.json    usuario/ab/c/d.json
# usuario/abcd.json     usuario/abc/d.json
RewriteRule ^(usuario/[a-z]+)([a-z])((?:/[a-z])*\.json)$ $1/$2$3  [N]

# URL:                  Reescrita:
# usuario/a.json        usuario/a/data.json
# usuario/a/b.json      usuario/a/b/data.json
# usuario/a/b/c.json    usuario/a/b/c/data.json
# usuario/a/b/c/d.json  usuario/a/b/c/d/data.json
RewriteRule ^(usuario(?:/[a-z])+)\.json$ $1/data.json             [L]

Example:

http://dominio.com.br/usuario/umnomedeusuariomuitolongo.json

Rewrite:

http://dominio.com.br/usuario/u/m/n/o/m/e/d/e/u/s/u/a/r/i/o/m/u/i/t/o/l/o/n/g/o/data.json

Description:

The regex is the last consecutive letter in the user name, adding the character / .
Or flag [N] causes the rule to run again if it matches.
The rule is executed again for each character, and the url is rewritten again after the last character is replaced, until there are no more characters to rewrite.
If the [N] flag is not compatible with your version of Apache, you can change it to [L] , but you should change MaxRedirects to allow many iterations.
