请参考如下demo：

//解压rawfile下文件 
function rawfileZlibDecompress() { 
  getContext().resourceManager.getRawFileContent('demo.zip', (_err, value) => { 
    let myBuffer: ArrayBufferLike = value.buffer 
    //将rawfile下的文件拷贝至沙箱下，沙箱路径：/data/storage/el2/base/haps/entry/files/demo.zip 
    let filePath = getContext().filesDir + '/demo.zip'; 
    let file = fs.openSync(filePath, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE); 
    let writeLen = fs.writeSync(file.fd, myBuffer); 
    hilog.info(0xFF00, LOG_TAG, `write data to file succeed and size is:${writeLen}`); 
    fs.closeSync(file); 
 
    let outFileDir = getContext().filesDir; 
    let options: zlib.Options = { 
      level: zlib.CompressLevel.COMPRESS_LEVEL_DEFAULT_COMPRESSION 
    }; 
    //解压沙箱下的文件 
    try { 
      zlib.decompressFile(filePath, outFileDir, options, (errData: BusinessError) => { 
        if (errData !== null) { 
          hilog.error(0xFF00, LOG_TAG, `errData is errCode:${errData.code}  message:${errData.message}`); 
        } 
      }) 
    } catch (errData) { 
      let code = (errData as BusinessError).code; 
      let message = (errData as BusinessError).message; 
      hilog.error(0xFF00, LOG_TAG, `errData is errCode:${code}  message:${message}`); 
    } 
  }) 
}
