golang iris validator

iris 并没有内置数据校验，所以使用go-playground的validator

package main

import (
    "github.com/go-playground/validator/v10"
    "github.com/kataras/iris/v12"
)

func main() {
    app := iris.New()
    app.Validator = validator.New()
    app.Post("/user", profile)
    app.Listen(":8080")
}

//{"name" : "Marx", "age" : 202}
func profile(ctx iris.Context) {
    var user User
    err := ctx.ReadJSON(&user)
    if err != nil {
        ctx.JSON("error")
        return
    }

    ctx.JSON("ok")
}

type User struct {
    Name string `json:"name" validate:"required"`
    Age  uint8  `json:"age" validate:"required,gte=0,lte=130"`
}
