我正在使用带有 ejs 的 node.js 构建一个测试网页（两者都是最新版本）。顺便说一句，每当我运行服务器时，它都会在下面显示错误消息。

ReferenceError: /Users/xxxxxxxx/Project/workspace/nodesails/views/user/signup.ejs:28
   26| 
   27|         <ul>
>> 28|             <% _.each(users, function(user) { %>
   29|             <li><%= user.name %> : <%= user.content %></li>
   30|             <% }) %>
   31|         </ul>

控制器（UserController.js）如下

var data = [
    {name: "Test 1", content:"xxxxxxxxxxxxxx"},
    {name: "Test 2", content:"zzzzzzzzzzzzzz"},
    {name: "Test 3", content:"yyyyyyyyyyyyyy"}
];

module.exports = {

    add: function(req, res) {
        res.send('Add a user');
    },

    remove: function(req, res) {
        res.send('Remove a user');
    },

    signup: function(req, res) {
        res.send('Signup here');

        return res.view({users: data});
    }
};

这是 routes.js 的一部分

'/user/signup': {
    view: 'user/signup'
},

最后，视图文件（view/user/signup.ejs）是

<div class="container clearfix">
    <div class="main">
        <h1 id="main-title">Register Here!</h1>

        <ul>
            <% _.each(users, function(user) { %>
            <li><%= user.name %> : <%= user.content %></li>
            <% }) %>
        </ul>
    </div>
</div>

我想我已经尽力了。请帮我一把。谢谢！

在您的控制器中，您的signup路线是错误的。您必须打电话res.render而不是res.view跳过res.send电话。目前你只返回一个字符串，当然这不起作用......

它应该是这样的

module.exports = {
  // ...
  signup: function(req, res) {
    res.render('signup', { users: data });
  }
};

signup您的视图在哪里（ signup.ejs，但您不必提供扩展名，因为 Express 会根据配置的视图引擎自动知道要使用哪个扩展名）。
