DeviceManager部件

简介

DeviceManager组件在OpenHarmony上提供账号无关的分布式设备的认证组网能力,并为开发者提供了一套用于分布式设备间监听、发现和认证的接口。

其组成及依赖如下所示:

dsoftbus提供能力: 提供设备上下线通知及设备信息,设备认证通道和设备发现能力。 deviceauth提供能力: 提供设备群组管理和群组认证能力。

约束

  • 开发语言:JS、C++
  • 适用于Hi3516DV300单板等OpenHarmony设备

废弃接口说明

该部分接口暂时可继续使用,但是暂停维护,建议使用新接口进行开发。

当前版本设备管理服务不具备权限管理的能力,接口中的system api仅供系统调用,后续版本会进行严格的权限管控。 接口参见interface_sdk-js仓库的 ohos.distributedHardware.deviceManager.d.ts

  • 公共接口:

    使用DeviceManager相关接口之前,需要通过createDeviceManager接口创建DeviceManager实例;

    不使用DeviceManager接口的时候需要释放对应的DeviceManager实例。

原型 描述
createDeviceManager(bundleName: string, callback: AsyncCallback<DeviceManager>): void; 以异步方法获取DeviceManager实例
release(): void; 释放DeviceManager实例
  • 系统能力接口:

    提供可信设备列表获取、可信设备状态监听、周边设备发现、设备认证等相关接口,该部分作为系统能力接口,仅供系统应用调用。

新增接口说明

从Openharmony 4.0.9.2版本开始,新增设备管理接口。

接口参见interface_sdk-js仓库的 ohos.distributedDeviceManager.d.ts

  • 公共接口:

    调用以下接口,需要申请ohos.permission.DISTRIBUTED_DATASYNC权限才能正常调用。

    使用DeviceManager相关接口之前,需要通过createDeviceManager接口创建DeviceManager实例;

try {
  let trustList = dmClass.getAvailableDeviceListSync();
  console.log("trustList:" + JSON.stringify(this.trustList));
} catch(err) {
  console.log("getAvailableDeviceList failed: " + JSON.stringify(err));
}
// 获取本地设备类型。
var data = dmClass.getLocalDeviceType();

// 获取本地设备名称。
var data = dmClass.getLocalDeviceName();

// 发现周边设备。
try {
  // 注册发现设备成功回调监听。
  dmClass.on('discoverSuccess', (data) => {

  'targetPkgName': 'xxxx',
  'appName': 'xxxx',
  'appOperation': 'xxxx',
  'customDescription': 'xxxx'

  // 释放DeviceManager实例。
  deviceManager.releaseDeviceManager(dmClass);
} catch (err) {
  console.log("err:" + err.code + "," + err.message);
}
  • 系统接口:

    该部分接口仅支持系统应用调用。 调用以下接口,需要申请ohos.permission.ACCESSS_SERVICE_DM权限才能正常调用。

原型 描述
replyUiAction(action: number, actionResult: string): void; 回复用户ui操作行为。此接口只能被devicemanager的PIN码hap使用。
on(type: 'replyResult', callback: Callback<{ param: string}>): void; 回复UI操作结果回调。
off(type: 'replyResult', callback?: Callback<{ param: string}>): void; 取消回复UI操作结果回调。
  • 示例如下:
// 设置用户ui操作行为
/*  action = 0 - 允许授权
    action = 1 - 取消授权
    action = 2 - 授权框用户操作超时
    action = 3 - 取消pin码框展示
    action = 4 - 取消pin码输入框展示
    action = 5 - pin码输入框确定操作
*/
try {
  let action = 0;
  dmClass.replyUiAction(action, "extra")
  dmClass.on('replyResult', (data) => {
    console.log("replyResult executed, dialog closed" + JSON.stringify(data))
    var tmpStr = JSON.parse(data.param)
    var isShow = tmpStr.verifyFailed
    console.log("replyResult executed, dialog closed" + isShow)
  });
} catch (err) {
  console.log("err:" + err.code + "," + err.message);
}

详细接口说明请参考API文档

系统弹框ServiceExtensionAbility

当前版本只支持PIN码认证,需要提供PIN码认证的授权提示界面、PIN码显示界面、PIN码输入界面;

当前,由于系统通过native层直接进行弹窗的能力尚不具备,这里使用ServiceExtensionAbility来进行对应界面的弹窗。

该ServiceExtensionAbility为:DeviceManager_UI.hap,作为系统应用进行预置。

  • 编译运行:

    将devicemanager/display工程导入DevEco Studio 2.2 Beta1,复制display目录下的@ohos.distributedHardware.deviceManager.d.ts文件到Sdk\js\2.2.0.1\api\common目录下,进行编译构建及运行调试.

  • 编译环境依赖:IDE 2.2 SDK6

  • DeviceManager_UI.hap包源码存放位置:device_manager仓库

  • UI显示:

    DeviceManager作为认证被控端,授权提示界面、PIN码显示界面由DeviceManager_UI ServiceExtensionAbility默认进行显示;

    DeviceManager作为认证发起端,PIN码输入界面可以选择由DeviceManager_UI ServiceExtensionAbility进行显示,还是由开发者自行显示。开发者如需自己定制PIN码输入界面,需要在authenticateDevice接口的认证参数AuthParam中,extraInfo属性里面指定displayOwner参数为1。
