Onebox improved error handling and support for Instagram Access Tokens (#11253) * FEATURE: display error if Oneboxing fails due to HTTP error - display warning if onebox URL is unresolvable - display warning if attributes are missing * FEATURE: Use new Instagram oEmbed endpoint if access token is configured Instagram requires an Access Token to access their oEmbed endpoint. The requirements (from https://developers.facebook.com/docs/instagram/oembed/) are as follows: - a Facebook Developer account, which you can create at developers.facebook.com - a registered Facebook app - the oEmbed Product added to the app - an Access Token - The Facebook app must be in Live Mode The generated Access Token, once added to SiteSetting.facebook_app_access_token, will be passed to onebox. Onebox can then use this token to access the oEmbed endpoint to generate a onebox for Instagram. * DEV: update user agent string * DEV: don’t do HEAD requests against news.yahoo.com * DEV: Bump onebox version from 2.1.5 to 2.1.6 * DEV: Avoid re-reading templates * DEV: Tweaks to onebox mustache templates * DEV: simplified error message for missing onebox data * Apply suggestions from code review Co-authored-by: Gerhard Schlager <mail@gerhard-schlager.at> 2020-11-19 01:55:16 +08:00			`<article class="onebox-warning-message">`
