Angular4：如何访问本地json？

您可以使用此代码

@Injectable()export class AppServices{    constructor(private http: Http) {         var obj;         this.getJSON().subscribe(data => obj=data, error => console.log(error));    }    public getJSON(): Observable<any> {         return this.http.get("./file.json")   .map((res:any) => res.json())   .catch((error:any) => console.log(error));     }}

这

file.json
