通过迁移工具处理的数据如何能看到呢？ HarmonyOS 鸿蒙Next

参考下文件读写demo，把备份目录下的文件读写到沙箱路径下：

fileWriteAndWrite(filePath:string,resultPath:string){
  // 打开文件
  let srcFile = fs.openSync(filePath, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE);
  // 读取源文件内容并写入至目的文件
  let destFile = fs.openSync(resultPath, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE);

  let bufSize = 4096;
  let readSize = 0;
  let buf = new ArrayBuffer(bufSize);
  let readOptions: ReadOptions = {
    offset: readSize,
    length: bufSize
  };
  let readLen = fs.readSync(srcFile.fd, buf, readOptions);
  while (readLen > 0) {
    readSize += readLen;
    let writeOptions: WriteOptions = {
      length: readLen
    };
    fs.writeSync(destFile.fd, buf, writeOptions);
    readOptions.offset = readSize;
    readLen = fs.readSync(srcFile.fd, buf, readOptions);
  }
  // 关闭文件
  fs.closeSync(srcFile);
  fs.closeSync(destFile);
}

1. 备份目录路径获取方式:

//1./data/storage/el1/base/.backup/restore/{APK包名}/de/
this.context.area = contextConstant.AreaMode.EL1;
let deSourcePath = this.context.backupDir +"restore/{APK包名}/de/"

1. 应用沙箱路径获取方式:

// 例如下列四个路径
/data/storage/el1/base/cache
/data/storage/el1/base/haps/entry/cache
/data/storage/el2/base/cache
/data/storage/el2/base/haps/entry/cache
//获取沙箱路径
let moduleContext: common.Context;
moduleContext = this.context.createModuleContext('entry');
console.log('moduleContext + el2: '+moduleContext.cacheDir);
console.log('UIAbilityContext + el2: '+this.context.cacheDir);
moduleContext.area = contextConstant.AreaMode.EL1;
console.log('moduleContext + el1: '+moduleContext.cacheDir);
this.context.area = contextConstant.AreaMode.EL1;
console.log('UIAbilityContext + el1: '+this.context.cacheDir);
