API方法与使用

isMatch 给定内容是否匹配正则（配合RegexUtil里的正则常量一起使用）

let url = "https://ohpm.openharmony.cn/#/cn/publisher/663b99a5788eb334c83d9cd5";
let blUrl = RegexUtil.isMatch(url, RegexUtil.REG_URL);

let num = "123479";
let blNum = RegexUtil.isMatch(num, RegexUtil.REG_NUMBERS);

let cardNo = "xxxxxxxxxxxxxxxxxx";
let blCardNo = RegexUtil.isMatch(cardNo, RegexUtil.REG_CITIZEN_ID);

let date = "2024-10-15 21:18";
let blDate = RegexUtil.isMatch(date, RegexUtil.REG_TIME);

isPhone 判断传入的电话号码格式是否正确

let phone: string = "xxxxxxxxxxx";
let bl = RegexUtil.isPhone(phone);

isDigits 检查字符串是否只包含数字字符

let str: string = "xxxxxxxxxxx";
let bl = RegexUtil.isDigits(str);

isEmail 判断传入的邮箱格式是否正确

let email: string = "xxxxxxxx@qq.com";
let bl2 = RegexUtil.isEmail(email);

isEmoji 判断字符串是否包含表情

let str = "hdc shell aa start -a EntryAbility -b com.harmony.utils in 253 ms";
let isEmoji = RegexUtil.isEmoji(str);

isValidCard 验证身份证号码的有效性

let bl1 = RegexUtil.isValidCard('xxxxxxxxxxxxxxxxxx'); //true
let bl2 = RegexUtil.isValidCard('xxxxxxxxxxxxxxxxxx'); //false (校验码错误)
let bl3 = RegexUtil.isValidCard("xxxxxxxxxxxxxxx"); //true (15位格式正确)
let bl4 = RegexUtil.isValidCard("xxxxxxxxxxxxxxx"); //false (格式错误)
