HarmonyOS 在ArkTS侧如何遍历resource的rawfile目录下的所有文件？

Question

rawfile指的是随工程内置进HAP包的文件。

Answer 1

可以手动遍历，读取rawfile下的目录和文件信息参考文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-resource-manager-V5\#getrawfilelistsync10

https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-file-fs-V5

将rawfile下文件拷贝至沙箱可参考示例如下：

getContext(this).resourceManager.getRawFileContent('test.txt', (_err, value) => {
  let myBuffer: ArrayBufferLike = value.buffer
  let context = getContext(this);
  //沙箱路径
  let filePath = context.filesDir + "/test.txt";
  console.log("testTag-filePath:" + filePath);
  let file = fs.openSync(filePath, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE);
  let writeLen = fs.writeSync(file.fd, myBuffer);
  console.info("testTag-write data to file succeed and size is:" + writeLen);
  fs.closeSync(file);
});
