结构体验证

用gin框架的数据验证，可以不用解析数据，减少if else，会简洁许多。

package main

import (
    "fmt"
    "time"

    "github.com/gin-gonic/gin"
)

//Person ..
type Person struct {
    //不能为空并且大于10
    Age      int       `form:"age" binding:"required,gt=10"`
    Name     string    `form:"name" binding:"required"`
    Birthday time.Time `form:"birthday" time_format:"2006-01-02" time_utc:"1"`
}

func main() {
    r := gin.Default()
    r.GET("/5lmh", func(c *gin.Context) {
        var person Person
        if err := c.ShouldBind(&person); err != nil {
            c.String(500, fmt.Sprint(err))
            return
        }
        c.String(200, fmt.Sprintf("%#v", person))
    })
    r.Run()
}
