Angular 2 Http delete send json in body

Question

Could Angular2 send json body via http method delete ?

I try it and it said error

ORIGINAL EXCEPTION: options.search.clone is not a function

service.ts

deletetag(tagid: number): Observable<any> {

    let body = JSON.stringify(
        {
            "token": "test",
            "content": {
                "tagId": tagid
            }
        }
    );

    let headers = new Headers({ 'Content-Type': 'application/json' });
    let options = new RequestOptions({ headers: headers });

    return this.http.delete("http://localhost:8080/backend/tag", body, options)
        .map(res => this.extractData(res))
        .catch(this.handleError);
}

component.ts

this.tagService.deletetag(1)
   .subscribe(
      data => { },
      error => { },
      () => { }
   );

As per RequestOptionsArgs interface and Http delete function argument, i think you need to send delete request as below :

deletetag(tagid: number): Observable<any> {

  let body = JSON.stringify(
      {
        "token": "test",
        "content": {
        "tagId": tagid
      }
    }
  );
  let headers = new Headers({ 'Content-Type': 'application/json' });
  let options = new RequestOptions({
    headers: headers,
    body : body
  });

  return this.http.delete("http://localhost:8080/backend/tag", options)
        .map(res => this.extractData(res))
        .catch(this.handleError);
}

Although this may work in angular, you may have issues server side with this: stackoverflow.com/a/25237188/3806701

in Angular 5, the RequestOptions is DEPRECATED, see angular.io/api/http/RequestOptions
