Open Harmony开发之分布式账本

Android小贾2024-02-29 10:45

简介

Demo基于Open Harmony系统使用ETS语言进行编写，本Demo主要通过设备认证、分布式拉起、分布式数据管理等功能来实现。

应用效果

设备认证,获取同一个局域网内的设备ID，并拉起应用
添加数据并在另一台设备显示该数据

开发步骤

1.新建Openharmony ETS工程

在DevEco Studio中点击File -> New Project ->[Standard]Empty Ability->Next，Language 选择ETS语言，最后点击Finish即创建成功。

2.界面代码编写
首页界面
复制代码 
 build() {
    Flex({ direction: FlexDirection.Column}) {
      //发现设备
      Button('发现设备', { type: ButtonType.Normal, stateEffect: true })

        .onClick(() =>{

      .height(50)
    }
    .height('100%')
    .layoutWeight(1)

  }
}

    }
    .margin({
      top:20,left:15
    })
    .width(50)
    .height(50)

  }
}
3.设备认证

设备认证是依赖 DeviceManager 组件来实现的，详细代码参考源码RemoteDeviceModel.ets

1.创建DeviceManager实例

复制代码 
 registerDeviceListCallback(callback) {
    if (typeof (this.#deviceManager) === 'undefined') {
      deviceManager.createDeviceManager('com.example.tictactoegame', (error, value) => {
        if (error) return
        this.#deviceManager = value;
        this.registerDeviceListCallback_(callback);
      });
    } else {
      this.registerDeviceListCallback_(callback);
    }
  }

2.查询可信设备列表

复制代码 
 var list = this.#deviceManager.getTrustedDeviceListSync();
    if (typeof (list) != 'undefined' && typeof (list.length) != 'undefined') {
      this.deviceList = list;
    }

3.注册设备上下线监听

复制代码 
this.#deviceManager.on('deviceStateChange', (data) => {
      switch (data.action) {
        case 0:
          this.deviceList[this.deviceList.length] = data.device;
          this.callback();
          if (this.authCallback != null) {
            this.authCallback();
            this.authCallback = null;
          }
          break;
        case 2:
          if (this.deviceList.length > 0) {
            for (var i = 0; i < this.deviceList.length; i++) {
              if (this.deviceList[i].deviceId === data.device.deviceId) {
                this.deviceList[i] = data.device;
                break;
              }
            }
          }
          this.callback();
          break;
        case 1:
          if (this.deviceList.length > 0) {
            var list = [];
            for (var i = 0; i < this.deviceList.length; i++) {
              if (this.deviceList[i].deviceId != data.device.deviceId) {
                list[i] = data.device;
              }
            }
            this.deviceList = list;
          }
          this.callback();
          break;
        default:
          break;
      }
    });

4.设备发现

复制代码 
this.#deviceManager.on('deviceFound', (data) => {
      for (let i = 0; i < this.discoverList.length; i++) {
        if (that.discoverList[i].deviceId === data.device.deviceId) {
          return;
        }
      }
      this.discoverList[this.discoverList.length] = data.device;
      this.callback();
    });

5.设备认证

复制代码 
authDevice(deviceInfo, callback){
    let extraInfo = {
      "targetPkgName": 'com.example.tictactoegame',
      "appName": 'com.example.tictactoegame',
      "appDescription": 'com.example.tictactoegame',
      "business": '0'
    };
    let authParam = {
      "authType": 1,
      "appIcon": '',
      "appThumbnail": '',
      "extraInfo": extraInfo
    };
    this.#deviceManager.authenticateDevice(deviceInfo, authParam, (err, data) => {
      if (err) {
        this.authCallback = null;
      } else {
        this.authCallback = callback;
      }
    });
  }
4.数据管理

分布式数据管理 依赖@ohos.data.distributedData模块实现，详细参考源码RemoteDataManager.ets

1.导入该模块

复制代码 
import factory from '@ohos.data.distributedData';

2.创建KVManager实例，用于管理数据库对象

复制代码 
  registerDataListCallback(callback) {
    let that = this
    if (this.kvManager == null) {
      try {
        const config = {
          userInfo: {
            userId: '0',
            userType: 0
          },
          bundleName: 'com.example.tictactoegame'
        }
        factory.createKVManager(config).then((manager) => {
          that.kvManager = manager
          that.registerDataListCallback_(callback)
        }).catch((err) => {
        })
      } catch (e) {
      }
    } else {
      this.registerDataListCallback_(callback)
    }
  }

3.创建并获取KVStore数据库

复制代码 
registerDataListCallback_(callback) {
    let that = this
    if (that.kvManager == null) {
      callback()
      return
    }
    if (that.kvStore == null) {
      try {
        let options =
          {
            createIfMissing: true,
            encrypt: false,
            backup: false,
            autoSync: true,
            kvStoreType: 1,
            securityLevel: 3
          }
        this.kvManager.getKVStore(this.STORE_ID, options).then((store) => {
          that.kvStore = store
          that._registerDataListCallback_(callback)
        }).catch((err) => {
        })
      } catch (e) {
      }
    } else {
      this._registerDataListCallback_(callback)
    }
  }

4.订阅指定类型的数据变更通知

复制代码 
  _registerDataListCallback_(callback) {
    let that = this
    if (that.kvManager == null) {
      callback()
      return
    }
    this.kvStore.on('dataChange', 1, function(data) {
      if (data) {
         that.arr = data.updateEntries
        callback()
      }
    })
  }

5.添加指定类型键值对到数据库

复制代码 
  startAbilityContinuation(deviceId) {
    let wantValue = {
      bundleName: 'com.example.tictactoegame',
      abilityName: 'com.example.tictactoegame.MainAbility',
      deviceId: deviceId,
      parameters: {
        uri: 'pages/Fight'
      }
    };
    featureAbility.startAbility({ want: wantValue }).then(() => {
      router.replace({ uri: 'pages/Fight' })
    });
  }
5.远程拉起设备app

使用 FeatureAbility 模块的startAbility接口拉起远程设备app

复制代码 
  startAbilityContinuation(deviceId) {
    let wantValue = {
      bundleName: 'com.example.tictactoegame',
      abilityName: 'com.example.tictactoegame.MainAbility',
      deviceId: deviceId,
      parameters: {
        uri: 'pages/Fight'
      }
    };
    featureAbility.startAbility({ want: wantValue }).then(() => {
      router.replace({ uri: 'pages/Fight' })
    });
  }
6.添加数据

新建一个账单数据 添加到分布式数据

复制代码 
this.remoteDataManager.dataChange("key2", JSON.stringify(this.TestKvData))

在另一台设备监听并获取显示该条数据

复制代码 
 private onPageShow() {

    this.remoteDataManager.registerDataListCallback(() => {
      let arr = this.remoteDataManager.arr[0]
      this.strTest = arr.value.value
      this.ProjectData = JSON.parse(this.strTest)
     
  }
