Redirect domain to default language NGINX

问题

Been struggling for so long to 301 redirect site.com to site.com/en and site.com/my-page to site.com/en/my-page

I manage to make the first redirect work, but not the second! also is it possible to use only one rule for both? So what is wrong with my second rule?

rewrite "^/(?![a-z]{2}|[a-z]{2}-[a-z]{2})$" /en redirect;
rewrite "^/(?![a-z]{2}|[a-z]{2}-[a-z]{2})/(.*)$" /en/$2 redirect;

Thanks a lot in advance.

回答1:

You don't have 2 capture groups in the the second regexp, only one. The first pair of parenthesis there is a negative lookahead, which doesn't create a capture group. That's why you cannot use $2 in redirect.

This redirect should replace both your rules:

rewrite "^((?!/([a-z]{2}|[a-z]{2}-[a-z]{2})(/|$)).*)$" /en$1 last;

I think you can approach it from the other angle, by defining relevant locations, e.g.:

location / {
    return 301 /en$request_uri;
}

location = /my-page {
    return 301 /en/my-page;
}

location /en/ {
   ...
}
