想在本机模拟一下post请求，但是一直500，err是type is not define,求助

//路由
var express = require('express');
var router = express.Router();

/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('user/index', { title: 'Express' });
});

router.get('/register',function(req,res,next){
  res.render('user/register' ,{title: 'Register'});
});

router.post('/register', function(req,res){  
  var user_type=req.body.user-type;
  var email=req.body.email; 
  var password=req.body.pswd;
  console.log("User type = "+user_type+", email = "+email+", password is "+password);  
  res.end("yes");  
});

// catch 404 and forward to error handler
