如何写har包的编译脚本？

import { harTasks } from '@ohos/hvigor-ohos-plugin'; 
import fs from 'fs' 
 
interface OhPackage { 
  name: string; 
  version: number; 
  description: string; 
  author: string; 
} 
 
export function renameHarTask(str?: string) { 
  return { 
    pluginId: 'RenameHarTaskID', 
    apply(pluginContext) { 
      pluginContext.registerTask({ 
        // 编写自定义任务 
        name: 'renameHarTask', 
        run: (taskContext) => { 
          //读取oh-package.json5，解析出version 
          const packageFile = taskContext.modulePath+'\\oh-package.json5'; 
          console.log('file: ', packageFile); 
          let fileContent = fs.readFileSync(packageFile, 'utf8'); 
          console.log(fileContent); 
          const content: OhPackage = JSON.parse(fileContent); 
          const version = content.version; 
          const author = content.author; 
 
          console.log('renameHarTask: ', taskContext.moduleName, taskContext.modulePath); 
          const sourceFile = taskContext.modulePath + '\\build\\default\\outputs\\default\\' + taskContext.moduleName + '.har'; 
          const targetFile = taskContext.modulePath + '\\build\\default\\outputs\\default\\' 
            + taskContext.moduleName + '-' + version + '-' + author +'.har'; 
          console.log('renameHarTask: sourceFile: ', sourceFile); 
          console.log('renameHarTask: targetFile: ', targetFile); 
          // 修改产物名 
          fs.rename(sourceFile, targetFile, (err)=> { 
            console.log('err: ' + err); 
          }); 
        }, 
        // 确认自定义任务插入位置 
        dependencies: ['default@PackageHar'], 
        postDependencies: ['assembleHar'] 
      }) 
    } 
  } 
} 
 
export default { 
  system: harTasks, 
  plugins:[renameHarTask()] 
}
