Vimeo oEmbed API URL incorrect causing Vimeo oEmbed to not function

[l3rady]

'#http://(www\.)?vimeo\.com/.*#i' => array( 'http://www.vimeo.com/api/oembed.{format}', true ),

Vimeo is registered as above (/wp-includes/class-oembed.php line 36). but looking at vimeo's API their API URL is without the www.

Because the wrong URL is used embed for vimeo videos does not work.

[SergeyBiryukov]

Confirmed.
Vimeo tries to redirect to a URL without www, but apparently double-encodes query args in the process.

This works:

http://vimeo.com/api/oembed.json?maxwidth=584&maxheight=600&url=http%3A%2F%2Fvimeo.com%2F30230507&format=json

This doesn't:

http://www.vimeo.com/api/oembed.json?maxwidth=584&maxheight=600&url=http%3A%2F%2Fvimeo.com%2F30230507&format=json

Full URL after redirect:

http://vimeo.com/api/oembed.json?maxwidth=584&maxheight=600&url=http%253A%252F%252Fvimeo.com%252F30230507&format=json

Note the double-encoded video URL: http%253A%252F%252Fvimeo.com%252F30230507.

Plugin to fix vimeo oembed provider

[gluten]

I whipped together a quick plugin as a hotfix for anyone who needs to fix this problem immediately.

Can definitely confirm this issue. Tried to include a video for at least 30 minutes. Maybe we should tell Vimeo to fix their redirect (regarding the double encoding) since it isn't really a bug in WordPress itself?

The temp fix (removing www) was deployed to WordPress.com yesterday.

Let's go ahead and change this in core, since it's clear that ^{vimeo.com is their preferred endpoint.}

I'm working with Vimeo on this to ensure the old endpoint works.

Update vimeo oembed api url. Props l3rady, justindgivens. fixes #18928

[nacin]

Vimeo was using mod_rewrite QSA without NE (noescape). That's been deployed and this is now fixed on their end as well.
