How to make AJAX call with angular2(ts)?

Question

How to make AJAX call with angular2(ts)? I read the tutorial on angularjs.org. But there is nothing about AJAX. So I really want to know how to make AJAX call with angular

Answer 1

AJAX is fully transparent in angularjs, see the links and examples below.

https://docs.angularjs.org/api/ng/service/$http

$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    // this callback will be called asynchronously
    // when the response is available
  }, function errorCallback(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });

https://docs.angularjs.org/api/ngResource/service/$resource

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