【HarmonyOS】鸿蒙应用OAID广告标识ID设置装备唯一标识
【HarmonyOS】广告标识ID设置装备唯一标识媒介
1.广告标识ID-OAID是什么？：
开放匿名装备标识符（Open Anonymous Device Identifier, OAID，以下简称OAID）：是一种非永世性装备标识符，基于开放匿名装备标识符，可在保护用户个人数据隐私安全的前提下，向用户提供个性化广告
2.OAID并非长期的唯一标识，不能当做DevicID使用：

固然OAID是装备级标识符，同一台装备上不同的App获取到的OAID值一样。
但是当用户规复手机出厂设置。用户操纵重置OAID。都会导致OAID厘革。并且最重要的是默认手机装备是没有开启【跨应用关联访问权限】，通过体系API获取到的是全0的值，没有效。只有当用户自动开启了，你去申请才气拿到值。
3.开启权限弹框的前置步骤
**【跨应用关联访问权限】**这个名字挺抽象的，你可以明白为安卓和苹果手机常说的跟踪访问大概广告ID权限。并且在鸿蒙中，同一台装备上当有应用去申请“跨应用关联访问权限”开关时，会初次生成OAID。
只有当用户开启时，调用API才会有自动提示用户授权的弹框，如下图：

调用函数：
import { identifier } from '@kit.AdsKit';
import { abilityAccessCtrl, common } from '@kit.AbilityKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { BusinessError } from '@kit.BasicServicesKit';
@Entry
@Component
struct Index {
onClickGetOAID = ()=>{
this.requestOAIDTrackingConsentPermissions(getContext());
}
private requestOAIDTrackingConsentPermissions(context: common.Context): void {
// 进入页面时，向用户请求授权广告跨应用关联访问权限
const atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
try {
atManager.requestPermissionsFromUser(context, ["ohos.permission.APP_TRACKING_CONSENT"]).then((data) => {
if (data.authResults === 0) {
hilog.info(0x0000, 'testTag', '%{public}s', 'succeeded in requesting permission');
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;
hilog.info(0x0000, 'testTag', '%{public}s', `succeeded in getting oaid by callback , oaid: ${oaid}`);
}
});
} else {
hilog.error(0x0000, 'testTag', '%{public}s', 'user rejected');
}
}).catch((err: BusinessError) => {
hilog.error(0x0000, 'testTag', '%{public}s', `request permission failed, error: ${err.code} ${err.message}`);
})
} catch (err) {
hilog.error(0x0000, 'testTag', '%{public}s', `catch err->${err.code}, ${err.message}`);
}
}
build() {
RelativeContainer() {
Text("点击请求用户OAID")
.id('IndexHelloWorld')
.fontSize(50)
.fontWeight(FontWeight.Bold)
.alignRules({
center: { anchor: '__container__', align: VerticalAlign.Center },
middle: { anchor: '__container__', align: HorizontalAlign.Center }
})
.onClick(this.onClickGetOAID)
}
.height('100%')
.width('100%')
}
}
申请权限配置文件：
