How to add language code after domain name on nginx

Question

I would like to add en-us language code on URL. The expectation is as follows.

When a user hits on http://example.com/, page should redirect users to http://example.com/en-us/ Note: I have achieved this with the following code.

location = / {
      rewrite ^ /en-us/ redirect;
  }

How to redirect customers to following scenarios

• http://example.com/contact, should redirect to http://example.com/en-us/contact
• http://example.com/en-us/, it shouldn't append extra en-us in url.
• http://example.com/en-in/, it shouldn't append en-us in url.

Simply, what i want to achieve is if there is no en-us in url, then we should add en-us in XX-XX place. http://example.com/XX-XX/contact

Answer 1

# Do nothing for assets (paths with a dot)

location ~ \. {
}

You can match locations that don't start with the required path by using a negative lookahead regex (?!)

# Paths that don't start  with /en-us/ are redirected:

location ~ ^(?!/en-(us|in)/) {
    rewrite ^/(.*)$ /en-us/$1 redirect;
}

Or using an if block:

if ($request_uri !~ "^/en-(us|in)/")
{
    return 301 /en-us/$request_uri;
}

Answer 2

Did you read the rewrite documentation? There are many similar examples there.

This is I'd do that (untested).

# Do not redirect /
location = / {
}

# Redirect everything else to /en-us/...
location / {
    rewrite ^/(.*)$ /en-us/$1 redirect;
}
