Advanced tools
npm install express-joi
npm install joi@17.4.0
const expressJoi = require('@escook/express-joi')
const express = require('express')
const app = express()
// 导入 Joi 来定义验证规则
const Joi = require('joi')
// 1. 导入 @escook/express-joi
const expressJoi = require('@escook/express-joi')
// 解析 x-www-form-urlencoded 格式的表单数据
app.use(express.urlencoded({ extended: false }))
// 2. 定义验证规则
// 注意:如果客户端提交的某些参数项未在 schema 中定义,
// 此时,这些多余的参数项默认会被忽略掉
const userSchema = {
// 2.1 校验 req.body 中的数据
body: {
username: Joi.string().alphanum().min(3).max(12).required(),
password: Joi.string()
.pattern(/^[\S]{6,15}$/)
.required(),
repassword: Joi.ref('password')
},
// 2.2 校验 req.query 中的数据
query: {
name: Joi.string().alphanum().min(3).required(),
age: Joi.number().integer().min(1).max(100).required()
},
// 2.3 校验 req.params 中的数据
params: {
id: Joi.number().integer().min(0).required()
}
}
// 3. 在路由中通过 expressJoi(userSchema) 的方式
// 调用中间件进行参数验证
app.post('/adduser/:id', expressJoi(userSchema), function (req, res) {
const body = req.body
res.send(body)
})
// 4.1 错误级别中间件
app.use(function (err, req, res, next) {
// 4.1 Joi 参数校验失败
if (err instanceof Joi.ValidationError) {
return res.send({
status: 1,
message: err.message
})
}
// 4.2 未知错误
res.send({
status: 1,
message: err.message
})
})
// 调用 app.listen 方法,指定端口号并启动web服务器
app.listen(3001, function () {
console.log('Express server running at http://127.0.0.1:3001')
})
更多的验证规则,请参考 Joi 的官方文档。
