 在接下来的挑战中，我们将会用到 <code>chat.pug</code> 文件。首先，你需要在你的 <code>routes.js</code> 文件中为 <code>/chat</code> 添加一个处理 GET 请求的路由，并给它传入 <code>ensureAuthenticated</code>。在回调函数中，我们需要让它 render <code>chat.pug</code> 文件，并在响应中包含 <code>{ user: req.user }</code> 信息。现在，请修改 <code>/auth/github/callback</code> 路由，让它可以像这样设置 user_id：<code>req.session.user_id = req.user.id</code>，并在设置完成后重定向至 <code>/chat</code>。

 The following challenges will make use of the <code>chat.pug</code> file. So, in your <code>routes.js</code> file, add a GET route pointing to <code>/chat</code> which makes use of <code>ensureAuthenticated</code>, and renders <code>chat.pug</code>, with <code>{ user: req.user }</code> passed as an argument to the response. Now, alter your existing <code>/auth/github/callback</code> route to set the <code>req.session.user_id = req.user.id</code>, and redirect to <code>/chat</code>.
