Flickr to require User-Agent in all API requests

[danhaber]

Flickr just announced they will be requiring a User-Agent in the header of all API calls.

A partial quote:

We will begin to require a user agent header on all API calls. Specifically, your calls will need to provide a “User-Agent” header, and the header needs to have a value that roughly describes your client. A good header for a client might look like “User-Agent: MySetManager/2.3” or “User-Agent: PHP_Flickr/1.0”. We believe this change will help us better manage traffic and improve our overall API availability.

More info here.

As far as curl is concerned, it should be as simple as adding something like this to the post() method:

curl_setopt($curl, CURLOPT_USERAGENT, 'User-Agent: PHP_Flickr/3.1');

Obviously, you may want to make it dynamic etc, but that's the idea.

I've added a similar fix to my fork of this: samwilson/phpflickr#60

Note: I don't think that CURLOPT_USERAGENT requires the User-Agent prefix, the docs say "The contents of the 'User-Agent: ' header to be used in a HTTP request."

Oh, nice fork! Good call regarding the prefix. I actually originally was using CURLOPT_HTTPHEADER, however right before creating the pull request I saw there was a CURLOPT_USERAGENT option and blindly replaced it. Fixed. Thank you.
