如何在 ANgular7 中传递 HttpUrl 中的字典对象？

Question

首先，如果我的问题很愚蠢，我想说对不起，我对此很困惑，因为我是 Angular 的新人。

在提问之前我想介绍一下我的代码，

这正是我调用的 get 函数 api,

  get(feepaid_report: FeepaidReport): Observable<FeepaidReport[]> {
    const options = this._utils.makeOptions(this._headers);
    return this._http.get(`${this._feepaidreportUrl}`, options).pipe(
      map((res: Response) => res.json()),
      tap(
        data => this.afterGetRequest(),
        error => { console.log(error); }
      ));
  }

在此代码中，_feepaidreportUrl 是我的 baseUrl，如下所示：

private _feepaidreportUrl = `${new Config().api}/report/feepaid_report/`;

我的 FeepaidReport 类型的参数 feepaid_report 带有这样的字典数据，

FeepaidReport: {paid_date: "2019-01-03", classes: "class12"}

我想在 url 中附加这个字典（即 feepaidreport 数据），这样我就可以像这样为后端传递 url：

baseurl/?paid_date=2019-01-03&classes=class12

希望你能理解我的问题

以上问题解决方法如下：

get(feepaid_report: FeepaidReport): Observable<FeepaidReport[]> {
  var url = `${this._feepaidreportUrl}/?`

   for(var key in feepaid_report){

      var val = feepaid_report[key];
       if (typeof(val) !=='undefined'){
        url = url + key + '=' + val + '&'
      }

    }



  const options = this._utils.makeOptions(this._headers);
    return this._http.get(url, options).pipe(
      map((res: Response) => res.json()),
      tap(
        data => this.afterGetRequest(),
        error => { console.log(error); }
      ));
  }
