Soundcloud's oEmbed endpoint works well with most links (e.g. affee), but returns a 403 status with the following (valid) URL: knifepartyinc
What is wrong with the second URL?
回答1:
the owner of the track on SoundCloud can choose to disable all widgets. It's one of the big checkboxes on the track edit page. In such case oEmbed wouldn't be able to return an embed code. Your application should have a defensive approach to handle this. Just check if the response is true before rendering it in the DOM.
