Node.js - EJS example
提问by jeffreyveon
I am trying to use Embedded Javascript renderer for node. I installed it using npm, as given here: https://github.com/visionmedia/ejs
我正在尝试为节点使用嵌入式 Javascript 渲染器。我使用 npm 安装它，如下所示：https: //github.com/visionmedia/ejs
And I have the following code, but it does not seem to work:
我有以下代码，但它似乎不起作用：
var connect = require('connect'),
ejs = require('ejs');
var server = connect.createServer(
connect.bodyDecoder(),
connect.methodOverride(),
connect.staticProvider(__dirname + '/public'),
function(req,res) {
ejs.render('hi');
}
);
server.listen(9000);
Any help greatly appreciated.
非常感谢任何帮助。

You need to send something to the response. From the connect hello-world
您需要向响应发送一些内容。从连接你好世界
var connect = require('../../lib/connect');
var server = connect.createServer(function(req, res){
var body = 'Hello World';
res.writeHead(200, {
'Content-Type': 'text/plain'
, 'Content-Length': body.length
});
res.end(body);
});
server.listen(3000);
console.log('Connect server listening on port 3000');
So for your app you'll want to replace:
因此，对于您的应用程序，您需要替换：
function(req,res) {
ejs.render('hi');
}
With something like:
像这样：
function(req,res) {
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end(ejs.render('hi'));
}
Does that work?
那样有用吗？

try this: (assuming you have the express and ejs modules installed)
试试这个：（假设你安装了 express 和 ejs 模块）
var express = require('express');
var app = express.createServer();
app.configure(function() {
app.use(express.bodyParser());
app.use(express.static('./static/'));
app.use(app.router);
});
app.set('view engine', 'ejs');
app.set('view options', {
layout: false
});
app.get('/', function(req, res) {
res.render('index', {
message : 'De groeten'
});
});
app.listen(3000);
and put a view in './views'. call it 'index.ejs' and fill it with some html:
并在“./views”中放置一个视图。将其命名为“index.ejs”并用一些 html 填充它：
<html>
<head>
<title></title>
</head>
<body>
<p>
<%= message %>
</p>
</body>
</html>
works for me!
对我来说有效！

Set your view engine to use ejs.
将您的视图引擎设置为使用 ejs。
app.set("view engine", "ejs");
Now set up the root route so that it will load something when you access your server from a browser, see below.
现在设置根路由，以便在您从浏览器访问服务器时加载一些内容，见下文。
var app = express();
// ROOT ROUTE
app.get("/", function(req, res) {
res.render("landingpage"); // use to render an ejs template page
res.send("hello world"); // to render an empty page with the hello world message
});
