Question

我正在尝试在Nodejs中创建一个post-receive挂钩，以便在我的Github repo更新后更新我的服务器。

我之前在php中做过这个。我现在正在使用Nodejs，我不确定应该如何实现它。

我查看了有关在ec2实例上设置nodejs的this博文。它说：

Create a post-recieve hook that will copy over new code after it’s been pushed to the repository

$ cat > hooks/post-receive

#!/bin/sh
GIT_WORK_TREE=/home/ubuntu/www
export GIT_WORK_TREE
git checkout -f

$ chmod +x hooks/post-receive

我不确定上面的代码究竟是做什么以及应该如何实现的。

有关最佳方法的任何想法吗？

我正在运行一个基本的32位Amazon Linux EC2实例。

git bare存储库不包含工作树。所以要使用你必须检查的文件。

将上述脚本放入（伪路径）ec2：mybaregitrepo / hooks / post-recieve将导致每次推送到ec2时都会运行。

这意味着：

#!/bin/sh
//set git working tree (the files you can use) to the path /home/ubuntu/www
GIT_WORK_TREE=/home/ubuntu/www
export GIT_WORK_TREE
//force git checkout so that your files will be put into the working tree.
git checkout -f

比：

//make the post-recieve hook executable so that it can run when you push commits to ec2
chmod +x hooks/post-receive

这是设置远程裸git仓库的一个不错的尝试 http://toroid.org/ams/git-website-howto

我的node（Express）应用在forever下运行，因此我使用以下处理程序，它基本上执行git pull并自行杀死（因此重生）。< / p>

function handleGitHub(req, res, next) {

  setTimeout(function() {
    var shouldRestart = !app.config.webhook || req.body.head_commit.message.indexOf(app.config.webhook) > -1;
    console.log('[GITHUB] WebHook Received for "%s" (WebHook: %s, Restart? %s)', req.body && req.body.head_commit.message, app.config.webhook && app.config.webhook, shouldRestart);
    if (!shouldRestart) {
      console.log('[GITHUB] Not restarting');
      return;
    }
    if (app.server_https && app.server_https.close) {
      console.log('[GITHUB] Closing HTTPS');
      app.server_https.close();
    }
    if (app.server && app.server.close) {
      console.log('[GITHUB] Closing HTTP');
      app.server.close();
    }
    setTimeout(function() {
      var spawn = require('child_process').spawn;

      var shell = process.env.SHELL;
      var args = ['-c', 'git pull'];

      var path = require('path');
      var projectPath = '/path/to/your/project/folder'; //or path.join(__dirname, '....

      var opts = { cwd: projectPath };

      console.log('[GITHUB] Spawning...', opts);

      var spawnProcess = spawn(shell, args, opts);

      spawnProcess.stdout.on('data', function(data) {
        // could log these
      });

      spawnProcess.stderr.on('data', function(data) {
        // could log these
      });

      spawnProcess.on('close', function(exitCode) {
        console.log('[GITHUB] Spawn finished', exitCode);
        console.log('[GITHUB] Exiting...');
        console.log('-------------------------------------------------------');
        process.exit(0);
      });

    }, 1000);

  }, 500);
  res.send(200, 'OK');
}

现在，只需使用指向此功能的路线：

app.post('/some_path_you_setup_in_github_web_hooks', handleGitHub);

您可以设置您的推钩 https://github.com/your_username/your_project/settings/hooks
