req.acceptedLanguages

An array containing the "acceptable" response languages specified by the user agent in the "Accept-Language" header of this request (req).

Usage

req.acceptedLanguages;

Details

req.acceptedLanguages contains all the languages specified by the request's Accept-Language header (see RFC-2616.)

This method is used by Sails internally for its implementation of internationalization and localization. The i18n hook automatically serves different content to different locales, based on the request.

Example

req.acceptedLanguages;
// -> ['en-US', 'en']

Notes

  • See the accepts module for the finer details of the header parsing algorithm used in Sails/Express/Koa/Connect.
  • Browsers send the "Accept-Language" header automatically based on the user's language settings.
  • You can expect the "Accept-Language" header to exist in most requests which originate from web browsers.
