angular 4 http删除方法不接受请求体

Question

我有一个删除请求，它将正文作为请求的一部分发送，如

import {RequestOptions, Request, RequestMethod} from '@angular/http';

    let headers = new Headers({ 'Content-Type': 'application/json' });
    this.http.delete('/api/deleteAddress', new RequestOptions({
       headers: headers,
       body: [{"folder":true}]
    }));
