Join Justin Schwartzenberger for an in-depth discussion in this video Using HTTP for GET calls, part of Angular 2 Essential Training (2016).
- [Voiceover] Angular has a class named HTTP…that is a service for making HTTP request calls…and returning HTTP responses.…Let's refactor the mediaItem service class…to use the HTTP class to make a GET request…for the mediaItems.…In the media-item.service.ts file,…we need to start by importing HTTP.…Angular has a model bundle for…all the HTTP stuff in 'angular2/http'.…Then we need a constructor that…takes in the HTTP, adding the type script…access modifier of private to…take advantage of the property initialization shortcut…and setting the type to HTTP.…
So we have a constructor requesting the HTTP type,…but since this is a service we dealt,…Angular does not know how to do…constructor injection on it,…but there's a decorator we can use to let it know.…It's the injectable decorator and…it's located in 'angular2/core'.…So we can add an import statement for that,…and then decorate the service class…with @Injectable and a pair of parentheses.…This decorator doesn't need any arguments passed to it.…It handles letting Angular know…
