根据此JSON文件在Web应用程序中的位置，您将能够使用Angular的Http客户端来执行GET请求并获取其数据。您甚至可以添加打字稿界面以期待结果。有点像这样：

import { Observable } from 'rxjs/Observable';
import { HttpClient } from '@angular/common/http';
export interface someInterface {
foo: string,
bar: number
}
export class SomeClass {
constructor(private http: HttpClient) { }
data: someInterface;
someFunc(){
this.http.get<someInterface>('/path/to/json').subscribe(result => {
this.data = result;
});
}
}
