Expressjs POST错误:TypeError:无法读取未定义的属性"title"

Question

我试了很多来弄清楚为什么会引发这个错误:

Configuring
Listening on 2000
TypeError: Cannot read property 'title' of undefined
   at /home/abdulsattar/learning/node/express/index.js:9:20

index.js:

var express = require("express"),
    app = express.createServer();

app.get("/", function(req, res) {
  res.send('<form action="/new" method="post"><input type="text" name="title" /><input type="submit" /></form>');
});

app.post("/new", function(req, res) {
  res.send(req.body.title);
});

app.configure(function() {
  console.log("Configuring");
  app.use(express.bodyParser());
});

var port = process.env.PORT || 2000;

app.listen(port, function() {
  console.log("Listening on " + port);
});

我读过快递需要的bodyParser().我use在上面,但它总是失败.我试了一下版本2.5.8和2.5.8(以为可能是问题),但它未能在两个版本.有什么我想念的吗？

我的预感,尝试在app.get和app.post之前移动app.configure语句.bodyParser中间件未被调用.另外,为了安全添加enctype到表单,不应该是必要的,但无论如何:application/x-www-form-urlencoded.

让我知道...
