HarmonyOS 鸿蒙Next 清除app缓存后，web的缓存没有立即清除掉

let cacheDir = getContext(this).cacheDir;
// let cacheDir = getContext(this).getApplicationContext().cacheDir;
console.info(cacheDir);
fileIo.listFile(cacheDir).then((filenames) => {
for (let i = 0; i < filenames.length; i++) {
let dirPath = cacheDir + ‘/’ + filenames[i];
console.log(dirPath);
// 判断是否为文件夹
let isDirectory: boolean = false;
try {
  isDirectory = fileIo.statSync(dirPath).isDirectory();
} catch (e) {
  console.error(JSON.stringify(e));
}

if (isDirectory) {
  fileIo.rmdirSync(dirPath);
} else {
// fileIo.unlinkSync(dirPath)
  fileIo.unlink(dirPath).then(() => {
console.info(‘remove file succeed’);
}).catch((err: Error) => {
  console.error('remove file failed with error message: ’ + err.message);
});
}
}
})
清除缓存后，重新打开web页面依然使用之前的缓存数据
