When requesting data from our webserver using the opensocial API call makeRequest, we can either post or get data using the code below

function getFriendList() {
var url = 'http://apps.yo.com/widgets/send_item/opensocial/profile_summary?user_id=' + gViewer.getId();
var params = {};
params[gadgets.io.RequestParameters.METHOD] = gadgets.io.MethodType.GET;
gadgets.io.makeRequest(url, getFriendListCallback, params);
}


As we can see, looking at the source of our page anyone can use the url to create they're own apps.

I can use $referrer = $_SERVER['HTTP_REFERER']; in PHP to know the request is coming from MySpace and so block any requests from other domains.

But what is there to stop another MySpace Dev from creating an application that uses my webserver?

 Hi Thomas:

You need to use signed makerequest() calls to address this issue which will pass a signature your server.

You also need to modify your server code to verify the signature passed in to ensure they match (i.e. this will validate that the request originated from Myspace - assuming the consumer secret has not been compromised).

Please add the following line to the JS code above to make signed requests:

params[gadgets.io.RequestParameters.AUTHORIZATION] = gadgets.io.AuthorizationType.SIGNED;
