HarmonyOS 新建日程提醒时如何设置提醒

CalendarManagerTest页面demo，省略了在onWindowStageCreate中创建 getCalendarManager ；

import { GlobalContext } from "../util/GlobalContext"
import calendarManager from '@ohos.calendarManager';
import { BusinessError } from '@kit.BasicServicesKit';

@Entry
@Component
struct CalendarManagerTest {
  @State message: string = 'Hello World';
  private calendarManager:calendarManager.CalendarManager = GlobalContext.getContext().getObject("calendarManager") as calendarManager.CalendarManager

  aboutToAppear(): void {
    this.test()
  }

  test(){
    //创建 calendar 对象
    let calendar: calendarManager.Calendar | undefined = undefined;
    //设置日程时间
    const date = new Date();
    const event: calendarManager.Event = {
      type: calendarManager.EventType.NORMAL,
      startTime: date.getTime() + 5 * 60 * 1000,
      endTime: date.getTime() + 10 * 60 * 1000,
      //[1,3,5]这种设置方式，会在日历中生成五个节点，分别在 startTime 前1分钟，3分钟 ，5分钟三个节点进行提示
      reminderTime: [1,3,5]
    };

    // getCalendar(callback: AsyncCallback<Calendar>): void

    this.calendarManager?.getCalendar().then((data: calendarManager.Calendar) => {
      console.info(`Succeeded to get calendar, data -> ${JSON.stringify(data)}`);
      calendar = data;
      calendar.addEvent(event, (err: BusinessError, data: number): void => {
        if (err) {
          console.error(`Failed to addEvent, err -> ${JSON.stringify(err)}`);
        } else {
          console.info(`Succeeded to add event, id -> ${data}`);
        }
      });
    }).catch((err: BusinessError) => {
      console.error(`Failed to get calendar, err -> ${JSON.stringify(err)}`);
    });
  }

  build() {
    RelativeContainer() {
      Text(this.message)
        .id('CalendarManagerTestHelloWorld')
        .fontSize(50)
        .fontWeight(FontWeight.Bold)
        .alignRules({
          center: { anchor: '__container__', align: VerticalAlign.Center },
          middle: { anchor: '__container__', align: HorizontalAlign.Center }
        })
        .onClick(()=>{
          this.test()
        })
    }
    .height('100%')
    .width('100%')
  }
}
