如果使用uuid包，可以导入验证并将id传递给它

const { v4: uuidv4, validate } = require('uuid');

const { id } = request.params;
validate(id) ? true : false;

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');
}

如果您想检查或验证特定的UUID版本，下面是相应的正则表达式。

注意，唯一的区别是版本号，这将在4.1.3中解释。UUID 4122 RFC的版本章节。

版本号是第三组的第一个字符:[VERSION_NUMBER][0-9A-F]{3}:

UUID v1: / ^ [0-9A-F] {8} - {4} [0-9A-F] [1] [0-9A-F] {3} - ab [89] [0-9A-F] {3} - [0-9A-F]{12} $ /我 UUID v2: / ^ [0-9A-F] {8} - {4} [0-9A-F] [2] [0-9A-F] {3} - ab [89] [0-9A-F] {3} - [0-9A-F]{12} $ /我 UUID v3: / ^ [0-9A-F] {8} - {4} [0-9A-F] [3] [0-9A-F] {3} - ab [89] [0-9A-F] {3} - [0-9A-F]{12} $ /我 UUID v4: / ^ [0-9A-F] {8} - {4} [0-9A-F] [4] [0-9A-F] {3} - ab [89] [0-9A-F] {3} - [0-9A-F]{12} $ /我 UUID v5: / ^ [0-9A-F] {8} - {4} [0-9A-F] [5] [0-9A-F] {3} - ab [89] [0-9A-F] {3} - [0-9A-F]{12} $ /我

正则表达式来拯救

/^[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}$/.test('01234567-9ABC-DEF0-1234-56789ABCDEF0');

或者用括号

/^\{?[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}‌​\}?$/

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

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)));
