angular what put in service controller
The $http service is a core AngularJS service that facilitates communication with the remote HTTP servers via the browser's XMLHttpRequest object or via JSONP. For unit testing applications that use $http service, see $httpBackend mock. For a higher level of abstraction, please check out the $resource service. Thus service is a stateless object that contains some useful functions. These functions can be called from anywhere; Controllers, Directive, Filters etc. Thus we can divide our application in logical units. The business logic or logic to call HTTP url to fetch data from server can be put within a service object. Tidy Up Your Angular Controllers with Factories and Services. By Brad Barrow April 30, 2014. There was a time, around five or six years ago, when jQuery was dominating the client side of the web. It read like plain English, it was easy to install, and the learning curve was flat enough for toddlers to ride their tricycles on it. Angular HOME Angular Intro Angular Expressions Angular Modules Angular Directives Angular Model Angular Data Binding Angular Controllers Angular Scopes Angular Filters Angular Services Angular Http Angular Tables Angular Select Angular SQL Angular DOM Angular Events Angular Forms Angular Validation Angular API Angular W3.CSS Angular Includes Angular ... Thus in the above angularjs injected service object to another service and in turn injected final service object to the controller object. You can inject same service object in multiple controllers. As angularjs service object is inheritedly singleton. Thus only one service object will be created per application. AngularJS $http. The AngularJS $http service makes a request to the server, and returns a response. Example. Make a simple request to the server, and display the result in a header: <div ng-app=myApp ng-controller=myCtrl>. <p>Today's welcome message is:</p>.

It read like plain English, it was easy to install, and the learning curve was flat enough for toddlers to ride their tricycles on it. To add headers for an HTTP method other than POST or PUT, simply add a new object with the lowercased HTTP method name as the key, e.g. $httpProvider.defaults.headers.get = { 'My-Header' : 'value' }. The defaults can also be set at runtime via the $http.defaults object in the same fashion. Remember that we’re approaching this in a “let’s get it working” fashion, because that’s often the reality we’re faced with. In the same way that one might’ve rushed to add a click handler with jQuery, Angular users will often reach for the quickest route to a working app: ng-controller. Let’s see how that might work. The application defines the customersCtrl controller, with a $scope and $http object. $http is an XMLHttpRequest object for requesting external data. $http.get() reads JSON data from https://www.w3schools.com/angular/customers.php.
