問題描述

學(xué)node沒多久，準(zhǔn)備用node做個(gè)注冊(cè)的功能， 但是注冊(cè)頁(yè)面的信息提交不到數(shù)據(jù)庫(kù)，數(shù)據(jù)庫(kù)用的mongodb，

注冊(cè)頁(yè)面

<p class='col-sm-8 col-sm-offset-1 main pull-left'> <form action='/signup' method='post' enctype='multipart/form-data'><p class='form-group'> <label for='inputName' class='col-sm-2 control-label'>用戶名</label> <p class='col-sm-4'><input type='text' name='username'> </p></p><p class='form-group'> <label for='inputPassword3' class='col-sm-2 control-label'>密碼</label> <p class='col-sm-4'><input type='password' name='password'> </p></p><p class='form-group'> <label for='' class='col-sm-2 control-label'>再次輸入密碼</label> <p class='col-sm-4'><input type='password' id='' name='re_password'> </p></p><p class='form-group'> <label for='inputEmail' class='col-sm-2 control-label'>郵箱</label> <p class='col-sm-4'><input type='email' name='email'> </p></p><p class='form-group'> <p class='col-sm-offset-2 col-sm-4'><button type='submit' class='btn btn-default'>注冊(cè)</butto> </p></p> </form></p>

注冊(cè)頁(yè)面路由

// 注冊(cè)頁(yè)面router.get(’/signup’, function(req, res, next){ res.render(’sign/signup’);});router.post(’/signup’, function(req, res, next){ // 獲取數(shù)據(jù) var name = req.body.username; var pwd = req.body.password; var re_pwd = req.body.re_password; var email = req.body.email; // 存入數(shù)據(jù)庫(kù) User.create({ userName: name, usePwd: pwd, userEmail: email },(err) => { if (err) next (err); res.redirect(’/signin’); })});

數(shù)據(jù)模型

const mongoose = require(‘mongoose’);mongoose.connect(‘mongodb://localhost/cnode’);var schema = new mongoose.Schema({name: String,pwd: Number,email: String});module.exports = mongoose.model(‘User’, schema);

填完注冊(cè)的信息后，成功的跳到了登錄頁(yè)面，但是這個(gè)時(shí)候數(shù)據(jù)庫(kù)確實(shí)這樣的

嘗試了四次全是這樣，這是怎么回事

問題解答

去掉注冊(cè)表單中enctype='multipart/form-data'

我似乎看見了問題.首先,

// 存入數(shù)據(jù)庫(kù) User.create({ userName: name, usePwd: pwd, userEmail: email },(err) => { if (err) next (err); res.redirect(’/signin’); })

用的屬性名是 userName, usePwd,useEmail,但是在 schema 定義中卻變成了 name, pwd, email

樓主代碼沒有完全貼全，從現(xiàn)有的代碼里猜測(cè)，schema 定義時(shí)的字段名，跟創(chuàng)建schema實(shí)例時(shí)傳入的object的字段名不一致導(dǎo)致？

// 存入數(shù)據(jù)庫(kù) User.create({ userName: name, usePwd: pwd, userEmail: email },(err) => { if (err) next (err); res.redirect(’/signin’); })

User.create({ userName: name, usePwd: pwd, userEmail: email },(err) => { if (err) next (err); res.redirect(’/signin’); })
