Amazon S3 on wamp localhost SSL error

Question

I'm trying to test in PHP Amazon S3 on my localhost but keep getting the same error:

Fatal error: Uncaught exception 'cURL_Exception' with message 'cURL resource: Resource id #69; cURL error: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed (cURL error code 60). See http://curl.haxx.se/libcurl/c/libcurl-errors.html for an explanation of error codes.' in C:\wamp\www\mysite\application\libraries\awsphp\lib\requestcore\requestcore.class.php:829 Stack trace: #0 C:\wamp\www\mysite\application\libraries\awsphp\sdk.class.php(1034): RequestCore->send_request() #1 C:\wamp\www\mysite\application\libraries\awsphp\services\sqs.class.php(250): CFRuntime->authenticate('ListQueues', Array) #2 C:\wamp\www\mysite\application\libraries\awsphp\services\sqs.class.php(582): AmazonSQS->authenticate('ListQueues', Array) #3 C:\wamp\www\mysite\application\controllers\uploads.php(33): AmazonSQS->list_queues() #4 [internal function]: Uploads->aw3() #5 C:\wamp\www\mysite\system\core\CodeIgniter.php(359): call_user_func in C:\wamp\www\mysite\application\libraries\awsphp\lib\requestcore\requestcore.class.php on line 829

Test code:

$sqs = new AmazonSQS();
$response = $sqs->list_queues();
var_dump($response->isOK());

I properly installed the AWS SDK to php files and enabled CURL and SSL on me local server. What can I do to make this work? I can't find any help online. I'm using wamp.

Answer 1

1. Get this file and save it to your hard drive. Call it cacert.pem.
2. Configure curl.cainfo in php.ini with the full path to the file downloaded in step 1.
3. Restart Apache.

I'll leave it as an exercise for the reader to find out why this fixes it, all the information you need can be found in the links above.
