In AngularJS (1.x), HTTP calls are made using the built-in $http service. It returns a promise and supports all standard HTTP methods.

Short answer (interview-friendly)

In AngularJS, HTTP calls are made using the $http service, which returns a promise and supports methods like GET, POST, PUT, and DELETE.

1. Basic $http GET request

app.controller('MyCtrl', function ($scope, $http) {

    $http.get('/api/users')
        .then(function (response) {
            // success
            $scope.users = response.data;
        })
        .catch(function (error) {
            // error
            console.error(error);
        });

});

2. POST request

$http.post('/api/users', {
    name: 'John',
    email: 'john@test.com'
})
.then(function (response) {
    console.log(response.data);
})
.catch(function (error) {
    console.error(error);
});

3. Full $http configuration object (recommended in real projects)

$http({
    method: 'PUT',
    url: '/api/users/1',
    data: {
        name: 'Updated Name'
    },
    headers: {
        'Content-Type': 'application/json'
    }
})
.then(function (response) {
    console.log(response.data);
})
.catch(function (error) {
    console.error(error);
});

4. Using $http in a service / factory (best practice)

app.factory('UserService', function ($http) {
    return {
        getUsers: function () {
            return $http.get('/api/users');
        },
        addUser: function (user) {
            return $http.post('/api/users', user);
        }
    };
});

Controller usage:

app.controller('MyCtrl', function ($scope, UserService) {

    UserService.getUsers()
        .then(function (res) {
            $scope.users = res.data;
        });

});

5. Handling response structure

AngularJS $http response object contains:

response.data     // actual response body
response.status   // HTTP status code
response.headers  // response headers
response.config   // request config

6. Older .success() / .error() (deprecated)

$http.get('/api/users')
    .success(function (data) {
        console.log(data);
    })
    .error(function (err) {
        console.error(err);
    });

Not recommended anymore—use .then() instead.

7. Common interview notes (important)

  • $http returns a promise
  • Internally uses XHR / Fetch
  • Supports interceptors
  • Can be wrapped in services for reuse
  • $httpBackend is used for unit testing
