Answer 1

请求授权时需要触发动态授权弹窗,看一下是不是没有触发授权弹窗。

可以参考以下代码以及文档

// ets
import identifier from '@ohos.identifier.oaid';
import hilog from '@ohos.hilog';
import { BusinessError } from '@ohos.base';
import abilityAccessCtrl from '@ohos.abilityAccessCtrl';
import common from '@ohos.app.ability.common';

@Entry
@Component
struct deviceDemo001 {

  build() {
    Column() {
      Text('测试')
        .width('100%')
        .backgroundColor('#131313')
        .height(50)
        .fontColor(Color.White)
        .onClick(()=>{
          const atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
          try {
            let context = getContext(this) as common.UIAbilityContext;
            atManager.requestPermissionsFromUser(context, ["ohos.permission.APP_TRACKING_CONSENT"]).then((data) => {
              if (data.authResults[0] == 0) {
                              identifier.getOAID((err: BusinessError, data: string) => {
                  if (err.code) {
                    hilog.error(0x0000, 'testTag', '%{public}s', `get oaid failed, error: ${err.code} ${err.message}`);
                  } else {
                    const oaid: string = data;
                                     }
                });
              } else {
                            }
            }).catch((err: BusinessError) => {
          
            })
          } catch(err) {
             }
        })
    }
  }
}
