Nodejs Version Message Encryption & Decryption of DingTalk..
Refer to Java version:
Issues: It's your turn!
- git clone
- npm install
- run 'EncryptTest.js' for main APIs and Utils.
- npm install --save dingtalk-encrypt
- use APIs as follows API Doc.
- Need constants:
TOKEN - Random string for signature, unrestricted, such as "123456".
ENCODING_AES_KEY - Secret key for callback data, random 43 characters of [a-z, A-Z, 0-9].
CORP_ID - DingTalk corpId from the Official OA.
-
Main APIs(Usage Example):
- getEncryptedMap
- getDecryptMsg
- getSignature
- encrypt
- decrypt
-
Utils [dingtalk-encrypt/Utils]:
- getRandomStr
- getRandomEncodingAesKey
-
Example
- 处理钉钉回调
// 参考:钉钉开发文档-业务事件回调 // eslint-disable-next-line @typescript-eslint/no-var-requires const DingTalkEncryptor = require('dingtalk-encrypt'); // eslint-disable-next-line @typescript-eslint/no-var-requires const utils = require('dingtalk-encrypt/Utils'); /** 加解密需要,可以随机填写。如 "12345" */ const TOKEN = utils.getRandomStr(6); /** 加密密钥,用于回调数据的加密,固定为43个字符,从[a-z, A-Z, 0-9]共62个字符中随机生成, 见 getRandomEncodingAesKey */ const ENCODING_AES_KEY = utils.getRandomEncodingAesKey(); console.log('ENCODING_AES_KEY: \n', ENCODING_AES_KEY); /** 企业corpid, 可以在钉钉企业管理后台查看(https://oa.dingtalk.com/) */ const CORP_ID = 'ding1234567890'; /** 实例化加密类 */ console.log('\nEncryptor Test:'); const encryptor = new DingTalkEncryptor(TOKEN, ENCODING_AES_KEY, CORP_ID); // 解密钉钉回调数据 const plainText = encryptor.getDecryptMsg(signature, timestamp, nonce, encryptMsg); console.log('DEBUG plainText: ' + plainText); const obj = JSON.parse(plainText); // 回调事件类型,根据事件类型和业务数据处理相应业务 const eventType = obj.EventType; // 响应数据:加密'success',签名等等 encryptor.getEncryptedMap('success', timestamp, utils.getRandomStr(8));
- 单独使用加/解密
/** 测试加解密响应报文或者字符串 */ const testJson = { EventType: 'bpms_instance_change', processInstanceId: 'ad253df6-e175caf-68085c60ba8a', corpId: 'ding2c4d8175651', createTime: 1495592259000, title: '自测-1016', type: 'start', staffId: 'er5875', url: 'https://aflow.dingtalk.com/dingtalk/mobile/homepage.htm', processCode: 'xxx', }; // console.log(JSON.parse(JSON.stringify(testJson))); // const unencryptedJson = 'success'; const unencryptedJson = JSON.stringify(testJson); console.log(` node unencryptedJson:\n ${unencryptedJson}`); const encryptedJson = encryptor.encrypt(ENCRYPT_RANDOM_16, unencryptedJson); console.log(` \nnode encryptedJson:\n ${encryptedJson}`); const decryptedJson = encryptor.decrypt(encryptedJson); console.log(` \nnode decryptedJson:\n ${decryptedJson}, (${decryptedJson.length})`); console.log(' \nnode sign:\n ' + encryptor.getSignature(TOKEN, timeStamp, nonce, encryptedJson));
