Instance Method Details

#add_lang_code(href, pattern, headers) ⇒ String

Adds language code to URL in “href” variable by “pattern” variable and own @lang_code.

When @lang_code is 'ja', add_lang_code('https://wovn.io', 'path', headers) returns 'https://wovn.io/ja/'.

If you want to know more examples, see also test/lib/lang_test.rb.

Parameters:

  • href (String) —

    original URL.

  • pattern (String) —

    url_pattern of the settings. (‘path’, ‘subdomain’ or ‘query’)

  • headers (Wovnrb::Header) —

    instance of Wovn::Header. It generates new env variable for original request.

Returns:

  • (String) —

    URL added langauge code.
