#鸿蒙通关秘籍#如何在HarmonyOS中实现AES加密的数据存取并处理不存在的键？

console.log('-------------------本地加密存储-------------------');
JhAESPreferencesUtils.saveString('testStr', '这是测试本地加密存储的字符串');
const testStr = JhAESPreferencesUtils.getString('testStr');
console.log(`testStr : ${testStr}`);

// 处理不存在的key情况
console.log('-------------------取不存在的key----------------------');

const testStr2 = JhAESPreferencesUtils.getString('testStr222');
console.log(`testStr2原始 : ${testStr2}`);
const test = testStr2 === '' ? '1' : '2222';
console.log(`testStr2 : ${testStr2}，变换后: ${test}`);

const testBool2 = JhAESPreferencesUtils.getBool('testBool222');
console.log(`testBool2 : ${testBool2}`);

const testInt2 = JhAESPreferencesUtils.getNumber('testInt222');
console.log(`testInt2: ${testInt2}`);

const testDouble2 = JhAESPreferencesUtils.getNumber('testDouble222');
console.log(`testDouble2 : ${testDouble2}`);

const testDic2 = JhAESPreferencesUtils.getModel('testDic222');
console.log(`testDic2 : ${testDic2}`);
