How to access the services from RESTful API in my angularjs page?

Question

I am very new to angularJS. I am searching for accessing services from RESTful API, but I didn't get any idea. How can I do that?

Answer 1

Option 1: $http service

AngularJS provides the $http service that does exactly what you want: Sending AJAX requests to web services and receiving data from them, using JSON (which is perfectly for talking to REST services).

To give an example (taken from the AngularJS documentation and slightly adapted):

$http({ method: 'GET', url: '/foo' }).   success(function (data, status, headers, config) {     // ...   }).   error(function (data, status, headers, config) {     // ...   }); 

Option 2: $resource service

Please note that there is also another service in AngularJS, the $resource service which provides access to REST services in a more high-level fashion (example again taken from AngularJS documentation):

var Users = $resource('/user/:userId', { userId: '@id' }); var user = Users.get({ userId: 123 }, function () {   user.abc = true;   user.$save(); }); 

Option 3: Restangular

Moreover, there are also third-party solutions, such as Restangular. See its documentation on how to use it. Basically, it's way more declarative and abstracts more of the details away from you.

Answer 2

The $http service can be used for general purpose AJAX. If you have a proper RESTful API, you should take a look at ngResource.

You might also take a look at Restangular, which is a third party library to handle REST APIs easy.
