在下面的Typescript代码中，我想调用一个需要导入的函数。我可以在类的构造函数中初始化导入，但我如何在公共函数中执行此操作？

import {Http} from "angular2/http";
export class AppComponent {
  constructor( properties.
    public http: Http
    ) {
      this.http.get(...){} //FUNCTION 1: this function works fine
      this.getAll(); //this does not work as FUNCTION 2 does not work
    }
 public getAll = function(){ //FUNCTION 2: this function does not work (cannot find name'http')
      http.get(...){} 
    }
 public otherfunction = function(){
      this.getAll(); //this does not work as FUNCTION 2 does not work
 }

公共属性可通过this（当前实例）引用访问：

public getAll = function() {
  this.http.get(...); 
}
