Utilizing AngularJs to retrieve data through the $http get method

Struggling to pass data back to my controller from my service without success. The service works as I can see the response in console log, but not in the controller.

Service:

(function () {
angular
    .module('app')
    .service('testService', testService);

testService.$inject = ['$http'];

function testService($http, url) {
    var baseUrl = "http://getjsondata.com/" + url;

    this.getData = function (url) {
        $http({
            method: 'GET',
            url: baseUrl + url,
            headers: {'Content-Type': 'application/json'}
        })
            .then(function (response) {
                console.log(response); // THIS WORKS
                return response;
            })
            .catch(function (error) {
                return error;
            });
    };
}
}());

Controller:

vm.getTestData = function (url) {
    vm.response = testService.getData(url);
    console.log(vm.response);
};

Attempted callbacks and factories, but still unable to access data in controller. Different ways of defining functions also tried. Return statement in service may be the issue. Seeking assistance!

Ensure getData function includes a return statement to avoid an endless loop. Update your controller to use .then method for better handling of asynchronous data.

this.getData = function (url) {
    return $http({
        method: 'GET',
        url: baseUrl + url,
        headers: {'Content-Type': 'application/json'}
    })
};

In the controller:

vm.getTestData = function (url) {
    testService.getData(url).then(function (response) {
        vm.response = response; 
        return response;
    })
    .catch(function (error) {
        return error;
    });
};
