HarmonyOS 鸿蒙Next 请问操作当前应用的缓存

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);
});
}
}
})
}
}
