一、开始一个node.js的WebHook的项目

相关配置DEMO

package.json

注意文件内秘钥配置为123，通过启动参数配置(Set SECRET_TOKEN=123)&& node index.js

{
  "name": "webhook.v2.demo",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "dev": "(Set SECRET_TOKEN=123)&& node index.js"
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/Coding/Webhook.v2.Demo.git"
  },
  "keywords": [
    "Coding.net",
    "Webhook"
  ],

  "bugs": {

  },
  "homepage": "https://github.com/Coding/Webhook.v2.Demo#readme",
  "dependencies": {
    "body-parser": "^1.18.2",
    "crypto": "^1.0.1",
    "express": "^4.16.3",
    "node-cmd": "^3.0.0"
  }
}

index.js

const express    = require('express');
const bodyParser = require('body-parser');
const crypto     = require('crypto');
const cmd        = require('node-cmd');

const verifyWebhook = (req) => {
	if (!req.headers['user-agent'].includes('Coding.net Hook')) {
		return false;
	}
	// Compare their hmac signature to our hmac signature
	// (hmac = hash-based message authentication code)
	const theirSignature = req.headers['x-coding-signature'];
	console.log(theirSignature);
	const payload = req.body;
	const secret  = process.env.SECRET_TOKEN;

	const ourSignature = `sha1=${crypto.createHmac('sha1', secret).update(payload).digest('hex')}`;
	return crypto.timingSafeEqual(Buffer.from(theirSignature), Buffer.from(ourSignature));
};

const app = express();
app.use(bodyParser.text({ type : '*/*' }));

const notAuthorized = (req, res) => {
	console.log('Someone who is NOT Coding is calling, redirect them');
	res.redirect(301, '/'); // Redirect to domain root
};

const authorizationSuccessful = () => {
	console.log('Coding is calling, do something here');

	// TODO: Do something here
	//此处执行CMD相关命令即可
	cmd.get(
		'notepad',//画图板
		function (data) {
			console.log("data")
		}
	);

	cmd.get(
		'C:\\Windows\\System32\\Calc.exe', //计算器
		function (data) {
			console.log("cacul")
		}
	);
};

app.post('*', (req, res) => {
	if (verifyWebhook(req)) {
		// Coding calling
		authorizationSuccessful();
		console.log('req', req);
		console.log('res', res);
		res.writeHead(200, { 'Content-Type' : 'text/plain' });
		res.end('Thanks Coding <3');
	} else {
		// Someone else calling
		notAuthorized(req, res);
	}
});

app.all('*', notAuthorized); // Only webhook requests allowed at this address

app.listen(3000);

console.log('Webhook service running at http://localhost:3000');
//console.info('secret', process.env.SECRET_TOKEN);

二、在coading的项目做相关配置

URL填写你的webhook项目访问地址
秘钥填写，package.json里面配置的（如：123）

配置成功后，可以在列表页面点击“测试”。
