The Google App Engine has no cURL support, which means that all REST calls need to be executed using file_get_contents.

As Parse REST calls need to be secure, you need to make sure that you send the request with a proper SSL context.

Short example of adding data using the Parse REST API from a Google App Engine application:

$data = array('data1' => 1113,
              'data2' => 'Alex',
              'data3' => false);
$context =
    array(
        "ssl"=>array(
            "allow_self_signed"=>true,
            "verify_peer"=>false,
        ),
        'http'=>
        array(
            "method" => "post",
            "header" => "X-Parse-Application-Id: YourAppID\r\n" .
                "X-Parse-REST-API-Key: YourRESTID\r\n" .
                "Content-Type: application/json\r\n",
                "content" => json_encode($data)

        )

    );
$context = stream_context_create($context);
$result = file_get_contents("https://api.parse.com/1/classes/yourClass", false, $context);

$data = array('data1' => 1113,

'data2' => 'Alex',

'data3' => false);

$context =

array(

"ssl"=>array(

"allow_self_signed"=>true,

"verify_peer"=>false,

'http'=>

array(

"method" => "post",

"header" => "X-Parse-Application-Id: YourAppID\r\n" .

"X-Parse-REST-API-Key: YourRESTID\r\n" .

"Content-Type: application/json\r\n",

"content" => json_encode($data)

)

);

$context = stream_context_create($context);

$result = file_get_contents("https://api.parse.com/1/classes/yourClass", false, $context);

Google App Engine PHP + Parse.com + Rest
