HarmonyOS 鸿蒙Next DeviceId如何获取？

参考demo如下,参考文档链接：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-distributeddevicemanager-V5#getlocaldeviceid

import { BusinessError } from '@ohos.base';

import deviceManager from '@ohos.distributedDeviceManager';

import common from '@ohos.app.ability.common';

import abilityAccessCtrl from '@ohos.abilityAccessCtrl';



@Entry

@Component

struct Device {

@State message: string = 'Hello World';

aboutToAppear(): void {

let context = getContext(this) as common.UIAbilityContext;

let atManager = abilityAccessCtrl.createAtManager();

try {

atManager.requestPermissionsFromUser(context, ['ohos.permission.DISTRIBUTED_DATASYNC']).then((data) => {

console.log('data: ' + JSON.stringify(data));

}).catch((err: object) => {

console.log('err: ' + JSON.stringify(err));

})

} catch (err) {

console.log('catch err->' + JSON.stringify(err));

}

}

build() {

Column () {

Text(this.message)

.id('HelloWorld')

.fontSize(50)

.fontWeight(FontWeight.Bold)

.onClick(() => {

try {

// 需要看一下自己的

let dmInstance = deviceManager.createDeviceManager('xxxxxx');

let deviceId: string = dmInstance.getLocalDeviceId();

console.log('local device id: ' + JSON.stringify(deviceId));

} catch (err) {

let e: BusinessError = err as BusinessError;

console.error('getLocalDeviceId errCode:' + e.code + ',errMessage:' + e.message);

}

})

}

.height('100%')

.width('100%')

}

}
