我想从JSON响应初始化类.我正在使用angular-http来获取打字稿中的JSON

在APP.TS：

class AppComponent {
 
  result: { [key: string]: string; };
  
  map: Map<Object,Object>;
  
  constructor(http: Http) {
    http.get('http://localhost/wptest/wp-json/wp/v2/posts').subscribe(res => {
      
      this.result = <any>res.json();
      this.map = <any>res.json();
      
      console.log(this.result);
      console.log(this.map);     
    });
  }
}

注意：
我仍然感到困惑的是哪个是我的JSON的正确类型
我读过打字稿不支持Map,但是它在这里工作：{[key：string]：string; };

我试着查看stackoverflow,我发现这个问题how to cast a json object to a typescript,答案与打字稿无关.

在另一个问题Can I create a TypeScript type and use that when AJAX returns JSON data?

答案是谈论在打字稿中创建接口. (我不太明白.)

我还发现json2ts的这个站点从JSON生成了typescript接口,所以我尝试了我的json,我得到了这个：

declare module namespace {
 
    export interface Guid {
        rendered: string;
    }
 
    export interface Title {
        rendered: string;
    }
 
    export interface Content {
        rendered: string;
    }
 
    export interface Excerpt {
        rendered: string;
    }
 
    export interface Self {
        href: string;
    }
 
    export interface Collection {
        href: string;
    }
 
    export interface Author {
        embeddable: boolean;
        href: string;
    }
 
    export interface Reply {
        embeddable: boolean;
        href: string;
    }
 
    export interface VersionHistory {
        href: string;
    }
 
    export interface Links {
        self: Self[];
        collection: Collection[];
        author: Author[];
        replies: Reply[];
    }
 
    export interface RootObject {
        id: number;
        date: Date;
        guid: Guid;
        modified: Date;
        modified_gmt: Date;
        slug: string;
        type: string;
        link: string;
        title: Title;
        content: Content;
        excerpt: Excerpt;
        author: number;
        featured_image: number;
        comment_status: string;
        ping_status: string;
        sticky: boolean;
        format: string;
        _links: Links;
    }
}

现在我的JSON有一个打字稿界面,但我不知道下一步该做什么！

问：这是将JSON解析为打字稿中的类对象的正确方法吗？如果是,使用数据初始化类的下一步是什么？
