问题
I'm attempting to have multiple title and descriptions for a same endpoint, one per language.
Trying to follow this documentation: https://developers.facebook.com/docs/opengraph/guides/internationalization#objects
I have a server that detects when the client is a bot, for example facebook bot, and it renders a single file with the title and description metas, and the following localization metas. I have a file for each language, and I set og:locale depending on the localization fb_locale that I recieve on the queryparams.
meta(property="og:locale" content="en_gb")
meta(property="og:locale:alternate" content="es_es")
meta(property="og:locale:alternate" content="it_it")
How can I have multiple language for the same endpoint? This is my testing app and endpoint I'm trying to translate: https://webapp-server-21b.herokuapp.com/marcp
It seems that it crawls it properly, but does not display the preview in the language I expect when I share it on FB or in the debugger of facebook.
If I perform :
curl -X POST -F "id=https://webapp-server-21b.herokuapp.com/marcp" -F "scrape=true" -F "locale=en_gb" "https://graph.facebook.com" -s
or:
curl -X POST -F "id=https://webapp-server-21b.herokuapp.com/marcp" -F "scrape=true" -F "locale=es_es" "https://graph.facebook.com" -s
I get the expected title in the corresponding expected language, but when I share on facebook or in the debugger it's always in english, the default locale.
Thanks!
