HarmonyOS 有没有相关清理缓存一套逻辑和相关代码呢

import fs from ‘@ohos.file.fs’; 
let cacheDir = context.cacheDir; 
@Entry 
@Component struct Clear_cache { 
  clearCache() { 
    // let cacheDir = getContext(this).cacheDir  
    // fs.rmdirSync(cacheDir)  
    // console.log(“delete !!!”)  
    fs.listFile(cacheDir).then((filenames) => { for (let i = 0;i < filenames.length; i++) { // let dirPath = cacheDir+filenames[i] let dirPath = ${cacheDir}/${filenames[i]} // 判断是否文件夹 let isDirectory try { isDirectory = fs.statSync(dirPath).isDirectory() } catch (e) { console.log(e) } if (isDirectory) { fs.rmdirSync(dirPath) } else { fs.unlink(dirPath).then(() => { console.info(“remove file succeed”); }).catch((err) => { console.info("remove file failed with error message: " + err.message + ", error code: " + err.code); }); 
    } 
    } 
  }) 
} 
}
