已淘汰Angular 6 RequestOptions搜索

从Angular 4迁移到Angular6。http似乎有所改变。在下面,我用于在请求选项中设置搜索。现在看来已不再如此。有人可以告诉我现在应该是什么样吗?

getSummaryStatistics(mid: string, cp: string): Observable<SummaryStatistics> {
    const params: HttpParams = new HttpParams();

    params.set('mid', mid);
    params.set('cp', cp);

    const headers = new HttpHeaders({
        'Accept': 'application/json'
    });

    let options = new Request({
        headers: headers,
        search: params //THIS IS WRONG
    });

    return this.http.get('Summary/SummaryStatistics', options)
        .map(response => <SummaryStatistics>response.json());  //ALSO .map NO LONG SEEMS TO WORK
}

这是Angular 6中的示例:

  getCadastralInformationByCoords(lat: any, lng: any, geom: boolean = true): Observable<CadastralParcel> {
    let urlToCall = urlAPIParcel;
    urlToCall += '?corx=' + lat;
    urlToCall += '&cory=' + lng;
    urlToCall += '&geom=' + geom;
    return this._http.get<CadastralParcel>(urlToCall).pipe(
      catchError(err => {
        return throwError(err);
      }));
  }

自Angular 5起,您无需使用response.json(),因为该方法默认情况下会键入调用。有关更多信息,请参见Oficcial docs
