HarmonyOS如何读取rawfile中的文件的，并返回byte数组

try { 
  this.context.resourceManager.getRawFileContent("XXX.json", (error: BusinessError, value: Uint8Array) => { 
    if (error != null) { 
      console.error("error is " + error); 
    } else { 
    } 
  }); 
} catch (error) { 
  let code = (error as BusinessError).code; 
  let message = (error as BusinessError).message; 
  console.error(`callback getRawFileContent failed, error code: ${code}, message: ${message}.`); 
}
