版本1到5，当version被省略时不使用多版本正则表达式。

const uuid_patterns = { 1: /^[0-9A-F]{8}-[0-9A-F]{4}-1[0-9A-F]{3}-[0-9A-F]{4}-[0-9A-F]{12}$/i, 2: /^[0-9A-F]{8}-[0-9A-F]{4}-2[0-9A-F]{3}-[0-9A-F]{4}-[0-9A-F]{12}$/i, 3: /^[0-9A-F]{8}-[0-9A-F]{4}-3[0-9A-F]{3}-[0-9A-F]{4}-[0-9A-F]{12}$/i, 4: /^[0-9A-F]{8}-[0-9A-F]{4}-4[0-9A-F]{3}-[89AB][0-9A-F]{3}-[0-9A-F]{12}$/i, 5: /^[0-9A-F]{8}-[0-9A-F]{4}-5[0-9A-F]{3}-[89AB][0-9A-F]{3}-[0-9A-F]{12}$/i }; const isUUID = (input, version) => { if(typeof input === "string"){ if(Object.keys(uuid_patterns).includes(typeof version === "string" ? version : String(version))){ return uuid_patterns[version].test(input); } else { return Object.values(uuid_patterns).some(pattern => pattern.test(input)); } } return false; } // Testing let valid = [ 'A987FBC9-4BED-3078-CF07-9141BA07C9F3', 'A987FBC9-4BED-4078-8F07-9141BA07C9F3', 'A987FBC9-4BED-5078-AF07-9141BA07C9F3', ]; let invalid = [ '', 'xxxA987FBC9-4BED-3078-CF07-9141BA07C9F3', 'A987FBC9-4BED-3078-CF07-9141BA07C9F3xxx', 'A987FBC94BED3078CF079141BA07C9F3', '934859', '987FBC9-4BED-3078-CF07A-9141BA07C9F3', 'AAAAAAAA-1111-1111-AAAG-111111111111', ]; valid.forEach(test => console.log("Valid case, result: "+isUUID(test))); invalid.forEach(test => console.log("Invalid case, result: "+isUUID(test)));

如果您使用uuid包，这个包会带来一个布尔验证函数，它会告诉您uuid是否有效。

例子:

import { validate as isValidUUID } from 'uuid';

if (!isValidUUID(tx.originId)) {
  return Promise.reject('Invalid OriginID');
}

我认为更好的方法是使用静态方法fromString来避免那些正则表达式。

    id = UUID.randomUUID();
    UUID uuid = UUID.fromString(id.toString());
    Assert.assertEquals(id.toString(), uuid.toString());

另一方面

   UUID uuidFalse = UUID.fromString("x");

抛出java.lang.IllegalArgumentException:无效UUID字符串:x

我向Apache Commons validator添加了一个UUID验证器。它还没有合并，但你可以在这里投票:

在Node中实现它的一个好方法是使用ajv包(https://github.com/epoberezkin/ajv)。

const Ajv = require('ajv');
const ajv = new Ajv({ allErrors: true, useDefaults: true, verbose: true });
const uuidSchema = { type: 'string', format: 'uuid' };
ajv.validate(uuidSchema, 'bogus'); // returns false
ajv.validate(uuidSchema, 'd42a8273-a4fe-4eb2-b4ee-c1fc57eb9865'); // returns true with v4 GUID
ajv.validate(uuidSchema, '892717ce-3bd8-11ea-b77f-2e728ce88125'); // returns true with a v1 GUID

使用.match()方法检查String是否为UUID。

public boolean isUUID(String s){
    return s.match("^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$");
}
