我想在（角度 5）中制作一个这样的可观察对象。如何responseType在 Angular 6 中声明？

Angular 5 代码：

public ExportSomeThing(
        ano: number
    ): Observable<IDownloadArquivo> {
        let q = this.http
            .get(this.apiUrl + ano + '/pordia/excel', {
                responseType: ResponseContentType.Blob  // <<<-- This code
            }).map((res) => { 

我的角度 6 代码：

public MyExport(
    ano: number
  ): Observable<IXpto> {
    let q = this.http
      .get( this.api_rul + ano + '/some_path/', {
        responseType: "ResponseContentType.Blob"  // <<<--- error here !!!
      }).map((res) => {

错误是：

[ts]
Argument of type '{ responseType: "ResponseContentType.Blob"; }' is not assignable to …

当我尝试在新机器上执行 npm start 时，出现以下错误：

我想为我的文件上传创建一个进度条。

我使用的上传是： https: //www.npmjs.com/package/ng2-file-upload。

日历在第一次加载时不显示事件。例如，仅当我触发任何事件（例如单击按钮）以将视图从月更改为周时。

我正在使用Angular Calendar 6 + LINK

我的项目是用Angular 6 制作的。

日历在第一次加载时不显示数据，只有在我触发任何事件之后才显示。

一切都按预期工作，所以我将给出 Html（其中的一部分）和最重要的：在这种情况下最重要的。

HTML ...

<div [ngSwitch]="view">
          <mwl-calendar-month-view *ngSwitchCase="CalendarView.Month" [viewDate]="viewDate" [events]="events"
            [refresh]="refresh" [activeDayIsOpen]="activeDayIsOpen" (dayClicked)="dayClicked($event.day)"
            (eventClicked)="handleEvent('Clicked', $event.event)" (eventTimesChanged)="eventTimesChanged($event)"
            [locale]="locale" [weekStartsOn]="weekStartsOn" [weekendDays]="weekendDays" >
          </mwl-calendar-month-view>
          <mwl-calendar-week-view *ngSwitchCase="CalendarView.Week" [viewDate]="viewDate" [events]="events"
