@ohos.enterprise.deviceInfo(设备信息管理)(系统接口)
本模块提供企业设备信息管理能力,包括获取设备序列号、设备名称等。
说明:
本模块首批接口从API version 10开始支持。后续版本的新增接口,采用上角标单独标记接口的起始版本。
本模块接口仅可在Stage模型下使用。
本模块接口仅对设备管理应用开放,需将设备管理应用激活后调用。
当前页面仅包含本模块的系统接口,其他公开接口参见。其他公开接口参见@ohos.enterprise.deviceInfo。
导入模块
import { deviceInfo } from '@kit.MDMKit';
deviceInfo.getDeviceSerial
getDeviceSerial(admin: Want, callback: AsyncCallback<string>): void
获取设备序列号,使用callback异步回调。
需要权限: ohos.permission.ENTERPRISE_GET_DEVICE_INFO
系统能力: SystemCapability.Customization.EnterpriseDeviceManager
参数:
参数名 | 类型 | 必填 | 说明 |
---|---|---|---|
admin | Want | 是 | 企业设备管理扩展组件。 |
callback | AsyncCallback<string> | 是 | 回调函数。当接口调用成功,err为null,data为设备序列号,否则err为错误对象。 |
错误码:
错误码ID | 错误信息 |
---|---|
9200001 | The application is not an administrator application of the device. |
9200002 | The administrator application does not have permission to manage the device. |
201 | Permission verification failed. The application does not have the permission required to call the API. |
202 | Permission verification failed. A non-system application calls a system API. |
401 | Parameter error. Possible causes: 1. Mandatory parameters are left unspecified; 2. Incorrect parameter types; 3. Parameter verification failed. |
示例:
import { Want } from '@kit.AbilityKit';
let wantTemp: Want = {
bundleName: 'com.example.myapplication',
