如何获取当前设备的设备名称

import deviceManager from ‘@ohos.distributedDeviceManager’; 
… 
let dmInstance = deviceManager.createDeviceManager(“com.example.myapplication”); 
//需要配置模块权限：ohos.permission.DISTRIBUTED_DATASYNC 
let localDeviceName = dmInstance.getLocalDeviceName(); 
使用如下接口可以获取，不需要设置权限： 
static test(context: Context) { 
  settings.getValue(context, settings.general.DEVICE_NAME).then((value) => { 
    console.log(...test value -> ${JSON.stringify(value)}) 
  }).catch((err: BusinessError) => { 
    console.error(...test error code: ${err.code}, message: ${err.message}); 
  }); 
}
