Express和Body-Parser不返回值

Question

我是nodejs和express的新手。我正在尝试使用body-parser从html页面获取POST值。我试着遵循了SO中的几个建议，但无法让它对我起作用。

下面是代码。任何指针都将受到高度赞赏。提前谢谢。

Server.js

    var express = require('express');
    var mongoose = require('mongoose');
    var bodyParser = require('body-parser');
    var Subscribe = require('./models/subscribe');

    mongoose.connect('CREDENTIALS');

    var app = express();

    app.use(bodyParser.json(), bodyParser.urlencoded({ extended: false }));

    var port = 3000;

    var router = express.Router();

    router.get('/', function(req, res) {
      res.json({ message: 'Test...' });
    });

    var subscribeRoute = router.route('/subscribe');
    subscribeRoute.post(function(req, res) {
      var subscribe = new Subscribe();

      subscribe.email = req.body.email_notify;
      console.log(subscribe);

      subscribe.save(function(err) {
        if (err)
            res.status(500).send(err);

        res.status(200);
      });
    });

    app.use('/api', router);
    app.listen(port);

index.html

    <form action="http://localhost:3000/api/subscribe/" method="POST" enctype="application/json">
    <input type="text" onfocus="if (this.value=='E-mail Address') this.value = ''" onblur="if (this.value=='') this.value = 'E-mail Address'" value="E-mail Address" id="email_notify" name="email_notify" />
    <button id="notify_me" ontouchstart="">Notify Me!</button><br/>
    </form>

谢谢Sujith

Answer 1

用<input type='submit'>代替<button>，并从表单中删除enctype。

此外，在Chrome中打开开发人员工具，网络选项卡，并检查请求是否已发送到服务器

Answer 2

改变这一点

app.use(bodyParser.json(), bodyParser.urlencoded({ extended: false }));

到这个

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
