NodeJS 用户注册/验证器

Question

我正在构建 NodeJS/Express 身份验证并尝试一些异步/等待(尝试/捕获(我的寄存器路由在我添加验证之前完美运行。问题是我的验证器(基于验证器(正在工作，按预期发送回错误，但是当我有正确的数据来注册用户时。邮递员正在给我空物。没有错误。我假设这个尝试/捕获的工作方式与我之前使用的 .then(( 不同。

问候

身份验证.js注册路由

const db = require('../models')
const validateRegisterInput = require('../validation/register')

exports.register = async (req, res, next) => {
const {
errors,
isValid
} = validateRegisterInput(req.body)
if (!isValid) {
return res.status(400).json(errors)
}
try {
const user = await db.User.create(req.body)
const {
id,
username
} = user
res.json({
id,
username
})
} catch (error) {
return next(error)
}
}

寄存器验证

const validator = require('validator')
const isEmpty = require('./is-empty')
const validateRegisterInput = (data) => {
let errors = {}
data.username = !isEmpty(data.username) ? data.username : ''
data.password = !isEmpty(data.password) ? data.password : ''
if (!validator.isLength(data.username, {
min: 2,
max: 30
})) {
errors.username = 'Username should be between 2 and 30 characters'
}
if (validator.isEmpty(data.username)) {
errors.username = 'Username is required'
}
if (validator.isEmpty(data.password)) {
errors.password = 'Password is required'
}
if (!validator.isLength(data.password, {
min: 6,
max: 30
})) {
errors.password = 'Password should be at least 6 characters'
}
return {
errors,
isValid: isEmpty(errors)
}
}
module.exports = validateRegisterInput

是EMpty

const isEmpty = (value) => {
value === undefined ||
value === null ||
(typeof value === 'object' && Object.keys(value).length === 0) ||
(typeof value === 'string' && value.trim().length === 0)
}
module.exports = isEmpty

>isEmpty缺少返回 - 因此返回总是undefined计算结果为 false。 或者 - 与其添加return，您当然可以删除大括号 {...}
