解説

The accepted values for this property follow the IETF BCP 47 standard for language tags, which typically include a language code, and optionally, a region code. If an unknown or unsupported locale is set, it is ignored. The Accept-Language header allows the client to specify one or more preferred languages, and the server can use this to provide localized content in the specified language(s).

Example values:

• >fr: French
• fr-CA: French (Canada)
• ja: Japanese
• ja-JP: Japanese (Japan)
• de: German

If the value specified does not match a recognized language or region, it is ignored, and the request will proceed without a specified 'Accept-Language' header. This allows you to request content in the language most appropriate for the user’s preferences.
