试图模拟 github webhook 请求，得到："X-Hub-Signature does not match blob signature"

Question

这里有一些代理服务器设置来处理 github webhooks：

require('dotenv').config();
var http = require('http');
var createHandler = require('github-webhook-handler');
var handler = createHandler({
  path: '/webhook',
  secret: process.env.GIT_WEBHOOK_SECRET
});

http
  .createServer(function(req, res) {
    handler(req, res, function(err) {
      res.statusCode = 404;
      res.end('no such location');
    });
  })
  .listen(8080);

handler.on('error', function(err) {
  console.error('Error:', err.message);
});

handler.on('push', function(event) {
  console.log(
    'Received a push event for %s to %s',
    event.payload.repository.name,
    event.payload.ref
  );
});

handler.on('issues', function(event) {
  console.log(
    'Received an issue event for %s action=%s: #%d %s',
    event.payload.repository.name,
    event.payload.action,
    event.payload.issue.number,
    event.payload.issue.title
  );
});

在 postman 中，我设置了这些 headers：

原始 body 在这里：https://developer.github.com/v3/activity/events/types/#pullrequestreviewevent

这是我的 pre-request 脚本：

var payload = request.data;
console.log("Using payload as " + payload)
var hash = CryptoJS.HmacSHA1(payload, environment.secret).toString(CryptoJS.enc.Hex)
postman.setGlobalVariable("signature", hash);

我可以确认 .env 中的 GIT_WEBHOOK_SECRET 与我的 Postman 环境设置中 secret 中的设置相同。

您需要将 X-Hub-Signature 的内容设置为带有 sha1 字段的参数：

var payload = request.data;
console.log("Using payload as " + payload)
var hash = CryptoJS.HmacSHA1(payload, environment.secret).toString(CryptoJS.enc.Hex)
postman.setGlobalVariable("signature", "sha1=" + hash);

来自 validating payloads from Github :

No matter which implementation you use, the hash signature starts with sha1=, using the key of your secret token and your payload body.
