尝试模拟github webhook请求，得到：＆＃34; X-Hub-Signature与blob签名不匹配＆＃34;

Question

这是一个处理github webhooks的小代理服务器设置：

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
  );
});

在邮差中，我设置了这些标题：

这是我的预请求脚本：

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Postman环境设置中secret中设置的内容相同。

Answer 1

您需要将X-Hub-Signature的内容设置为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：

  

无论您使用哪种实现，哈希签名都以   sha1 =，使用您的秘密令牌和您的有效负载体的密钥。
