Re: [cc-devel] cc-devel Digest, Vol 65, Issue 4

Hello again Lisa,
After first replying to your issue earlier today, I realized that you were right in your assumption that a change must have been introduced by the recent updates made to the API. 


The /license/standard/get API call was supposed to only support HTTP GET 
requests, but looking back on the old codebase reveals that this wasn't 
always the case. HTTP POST requests were being supported even though our 
doc's said otherwise.



I've updated our existing codebase to be backwards compatible and accept 
POST requests to the /license/standard/get call. Changing your code is 
no longer necessary, but I would still recommend changing the URL of the 
API call to ../issue if you insist on making POST requests.



Apologies for not accepting responsibility earlier on and thank you for 
bringing this issue to our attention!


Thanks,
-John Doig

Hello Lisa,


The issue appears to be that you are attempting to POST to an URL that 
does not accept POST requests. If you change the line:



$ch = 
curl_init('http://api.creativecommons.org/rest/1.5/license/standard/get');


to:


$ch = 
curl_init('http://api.creativecommons.org/rest/1.5/license/standard/issue');


then your call to the API will return a result other than "None."


For more information about the 'issue' and 'get' API calls, you can 
view the API's documentation at 
http://api.creativecommons.org/docs/readme_15.html#license-class-get. 
Hope this helps resolve your issue!

Hi there -


Recently -- within the last couple of weeks or so -- one of our 
processes here that relies on a call to the CC API stopped working.



We use cURL and PHP to post data to the CC API and get back the 
license URI. Here's the function that we use -- this hasn't been 
changed in months:


function makeCCLicense($commercial, $derivatives, $jurisdiction)
{

$ch = 
curl_init('http://api.creativecommons.org/rest/1.5/license/standard/get' 
<http://api.creativecommons.org/rest/1.5/license/standard/get%27>);

curl_setopt($ch, CURLOPT_POST, TRUE);

curl_setopt($ch, CURLOPT_POSTFIELDS, 'commercial=' . $commercial . 
'&derivatives=' . $derivatives . '&jurisdiction=' . $jurisdiction);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$result = curl_exec($ch);
curl_close($ch);
....}


I've been testing for clues and have set this up to print the 
contents of the $result variable to the screen. I get "None". I used 
to get something like 
"http://creativecommons.org/licenses/by-nc-nd/3.0/us/";, depending on 
the chooser's choices.



I've run out of things to check/tweak on our side. I'm now wondering 
if we are experiencing this problem due to the changes that you all 
just did to the API?


Appreciate any help you can offer - thanks!
~Lisa

    This is a bit of a late reply, but -- it's *great* to see the
    'deprecated'
    metadata showing up in the REST API. That's excellent.

    And the new Public Domain stuff Mark work been a long time coming.
    A lot
    of CC fans really appreciate the work CC is doing on revising
    that, and so

    it's a really welcome sign that it's stable enough to land in the 
API.
