【中文标题】使用 EJS 模板引擎在 Node.js 中提交表单后，我不断收到验证器错误【英文标题】：I keep getting validator errors after submitting my form in Node.js using EJS templating engine 【发布时间】：2021-10-03 11:13:46 【问题描述】：当我使用 Postman 发出请求时，代码运行良好且完美。但是每当我从前端发送相同的请求时，我都会收到此错误。
Result
formatter: [Function: formatter],
errors: [
value: undefined,
msg: 'Please enter your name',
param: 'name',
location: 'body'
,
value: '',
msg: 'Please enter a valid Email',
param: 'email',
location: 'body'
,
value: undefined,
msg: 'Please enter a password with 6 or more characters',
param: 'password',
location: 'body'
]
这是我的 signup.ejs 文件。
<!doctype html>
<html lang="en">
<%- include('./partials/header.ejs')%>
<%- include('./partials/navbar.ejs')%>
<body>
<section class="form my-4 mx-5">
<div class="container">
<div class="row no-gutter">
<div class="col-lg-5">
<img src="/images/joyce-busola-Nnv0DHFG1Ds-unsplash.jpg" class="img-fluid">
</div>
<div class="col-lg-7 px-5 pt-5">
<h1 class="font-weight-bold py-3">Queue's</h1>
<h4>Register your new Account</h4>
<form action="/user/register" method="POST">
<div class="form-row">
<div class="col-lg-7">
<input type="text" id="name" class="form-control my-3 p-3" placeholder="your name">
</div>
</div>
<div class="form-row">
<div class="col-lg-7">
<input type="email" id="email" class="form-control my-3 p-3" placeholder="email address">
</div>
</div>
<div class="form-row">
<div class="col-lg-7 input-group">

<div class="input-group-addon my-3 p-3">
</a><i class="bi bi-eye-slash" id="togglePassword"></i>
</div>
</div>
</div>
<div class="form-row">
<div class="col-lg-7">
<button type="submit" class="btn1 mt-3 mb-5">Register</button>
</div>
</div>
<a href="#">forgot password</a>
<p>Already have an acount? <a href="/user/login">Login here</a></p>
</form>
</div>
</div>
</div>
</section>
<%- include('./partials/footer.ejs')%>
</body>
</html>
这是我的注册控制器对象的副本。
require('dotenv').config();
const jwt = require('jsonwebtoken');
const User = require('../models/User');
const createToken = require('../middleware/auth_middleware');
const maxAge = 36000;
module.exports.register_post = async (req, res) =>
const name, email, password = req.body;
// Searching if User already exists
try
let user = await User.findOne( email );
if(user) return res.status(400).json( errors : [ msg: "User already exists"],);
// Create User Object
user = new User( name, email, password );
// Saving new User
await user.save();
// Creating User token with JWT
let payLoad = user._id;
const prize = createToken(payLoad);
res.cookie('jwt', prize,
httpOnly: true,
maxAge : maxAge * 1000
);
res.status(201).json(
msg: `$user.email successfully registered`,
name: user.name,
email: user.email);
console.log(user, prize);
catch (error)
console.log(error.message);
res.status(500).send('Server error')
;
我制作了一个中间件来使用 express-validator 处理验证。这是验证器文件。
require('dotenv').config()
const check, validationResult = require('express-validator');
const jwt = require('jsonwebtoken');
const maxAge = 36000;
const secret = process.env.JWT_SECRET;
const authValidator = () =>
return [
check('name', 'Please enter your name').not().isEmpty(),
check('email', 'Please enter a valid Email').trim().isEmail(),
check('password', 'Please enter a password with 6 or more characters').isLength(min:6)
];
const validateError = (req, res, next) =>
const errors = validationResult(req);
if(errors.isEmpty())
return next()
const extractedErrors = [];
errors.array().map(err => extractedErrors.push( [err.param]: err.msg ))
console.log(errors);
return res.status(400).json( errors: extractedErrors )
这是注册路由器文件
const express = require('express');
const router = express.Router();
const userController = require('../controllers/userController');
const authValidator, validateError = require('../middleware/auth_middleware');
router.get('/login', userController.login_get );
router.post('/login', userController.login_post );
router.get('/register', userController.register_get );
router.post('/register', authValidator(), validateError, userController.register_post );
module.exports = router;
【问题讨论】：
【参考方案1】：您的输入字段缺少name 字段。这就是在请求正文中找不到输入数据的原因。
例如对于电子邮件字段：
<div class="form-row">
<div class="col-lg-7">
<input type="email" name="email" id="email" class="form-control my-3 p-3" placeholder="email address">
</div>
</div>
