    <input type="text" name="email" placeholder="Email Address">

  <div class="field">
    <label>Password</label>
    <input type="password" name="password" placeholder="Password">

  <center><button class="ui button" type="submit">Submit</button></center>
</form>

我有一个创建像这样的新用户对象的函数......

function user(name, pass) {
   return {
      name: name,
      pass: pass
   };
}

以下是我如何从表单中检索信息。这是routes.js：

router.post('/register', (req,res) => {
var name = req.body.username;
var pass = req.body.password;
var email = req.body.email;

if (!name || !pass || !email ) {
  res.redirect('registration?code=fail');
} else{
db.insertUser(creations.user(name,pass,email,false),(user) => {
  if(user){
    db.login(user,(sessionID)=>{
      res.cookie('sessionID', sessionID);
      res.redirect('/feed');
    })
  } else res.redirect('registration?code=IU');
})
}})
