判断通知授权

应用需要获取用户授权才能发送通知。在通知发布前调用 requestEnableNotification()方法，弹窗让用户选择是否允许发送通知，后续再次调用 requestEnableNotification()方法时，则不再弹窗。

接口说明

• 查询通知是否授权

isNotificationEnabled():Promise<boolean>

• 请求发送通知的许可，第一次调用会弹窗让用户选择。

requestEnableNotification(context: UIAbilityContext): Promise<void>

开发步骤

导入 NotificationManager 模块

import { notificationManager } from "@kit.NotificationKit";
import { BusinessError } from "@kit.BasicServicesKit";
import { hilog } from "@kit.PerformanceAnalysisKit";
import { common } from "@kit.AbilityKit";

const TAG: string = "[PublishOperation]";
const DOMAIN_NUMBER: number = 0xff00;

请求通知授权。

可通过 requestEnableNotification 的错误码判断用户是否授权。若返回的错误码为 1600004，即为拒绝授权。

let context = getContext(this) as common.UIAbilityContext;
notificationManager.isNotificationEnabled().then((data: boolean) => {
  hilog.info(DOMAIN_NUMBER, TAG, "isNotificationEnabled success, data: " + JSON.stringify(data));
  if(!data){
    notificationManager.requestEnableNotification(context).then(() => {
      hilog.info(DOMAIN_NUMBER, TAG, `[ANS] requestEnableNotification success`);
    }).catch((err : BusinessError) => {
      if(1600004 == err.code){
        hilog.error(DOMAIN_NUMBER, TAG, `[ANS] requestEnableNotification refused, code is ${err.code}, message is ${err.message}`);
      } else {
        hilog.error(DOMAIN_NUMBER, TAG, `[ANS] requestEnableNotification failed, code is ${err.code}, message is ${err.message}`);
      }
    });
  }
}).catch((err : BusinessError) => {
    hilog.error(DOMAIN_NUMBER, TAG, `isNotificationEnabled fail: ${JSON.stringify(err)}`);
});
