JavaScript StackMob SDK using OAuth 1.0

gistfile1.js

        _.extend(StackMob, {
			'ajax': function(model, params, method) {

				var oauth = new OAuth({
				        consumerKey: 'XXXXXXXXXXXXXXXXXXXXXX',
				        consumerSecret: 'XXXXXXXXXXXXXXXXXXXXXXX'}
				    );

				var success = params['success'];
				var defaultSuccess = function(response, options) {

					var result = response && response.text ? JSON.parse(response.text) : null;
					if(params["stackmob_count"] === true)
					result = response;

					StackMob.onsuccess(model, method, params, result, success);

				};

				var error = params['error'];
				var defaultError = function(response, options) {
		        	var responseText = response.responseText || response.text;
					StackMob.onerror(response, responseText, null, model, params, error);
		        }
	
			var header = params['headers'];
		        header['Content-Type'] = 'application/json';
				oauth.request({
       				method : params['type'],
			        headers: header,
			        url: params['url'],
			        data: params['data'],
			        success: defaultSuccess,
			        failure: defaultError
			    });

			},
			'apiURL': 'http://api.stackmob.com' 
			}
		);

You can also do: https://api.stackmob.com if you'd like SSL :)

there was a bug in the original code, if the content-type is not set, the POSTs fail.
