hsp模块里rawfile文件读取问题

getContext(this) 
  .createModuleContext('hsp的module.json5里面的name') 
  .resourceManager 
  .getRawFileContent('文件名') 
  .then(） 
demo: 
  getContext(this) 
    .createModuleContext('hsp') 
    .resourceManager 
    .getRawFileContent('book2.txt') 
    .then((value: Uint8Array) => { 
      let rawBuffer = value.buffer 
      // let fileParentPath = getContext(this).cacheDir 
      let fileParentPath = getContext(this).getApplicationContext().filesDir+"/book/" + 12345 + "/" + 6789 
      if (!fs.accessSync(fileParentPath)) { 
        fs.mkdirSync(fileParentPath, true); 
      } 
      let filePath = fileParentPath + '/book2.txt' 
      let file = fs.openSync(filePath, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE) 
      let writeLen = fs.writeSync(file.fd, rawBuffer) 
      console.info("write data to file succeed and size is:" + writeLen); 
      fs.closeSync(file) 
    }) 
    .catch((error: BusinessError) => { 
      console.error("getRawFileContent promise error is " + error); 
    })
