req.acceptedLanguages

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

Usage

  1. 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

  1. req.acceptedLanguages;
  2. // -> ['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.
