根据此JSON文件在Web应用程序中的位置，您可以使用Angular的Http客户端执行GET请求并获取其数据。您甚至可以添加一个打字稿界面来获得结果。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;
    });
  }
}
