Undefined validation function 'bookabledate' on field 'CheckIn'
有没有报这个错的,win
最新版本,到底是要写binding还是validate呢?gin框架文档写的binding,validator文档写的是validate
试了很多版本都没有成功,最后试了一下官网的实例:https://github.com/gin-gonic/gin#custom-validators
package main
import (
"net/http"
"time"
"github.com/gin-gonic/gin"
"github.com/gin-gonic/gin/binding"
"github.com/go-playground/validator"
)
// Booking contains binded and validated data.
type Booking struct {
CheckIn time.Time `form:"check_in" binding:"required,bookabledate" time_format:"2006-01-02"`
CheckOut time.Time `form:"check_out" binding:"required,gtfield=CheckIn" time_format:"2006-01-02"`
}
var bookableDate validator.Func = func(fl validator.FieldLevel) bool {
date, ok := fl.Field().Interface().(time.Time)
if ok {
today := time.Now()
if today.After(date) {
return false
}
}
return true
}
func main() {
route := gin.Default()
if v, ok := binding.Validator.Engine().(*validator.Validate); ok {
v.RegisterValidation("bookabledate", bookableDate)
}
route.GET("/bookable", getBookable)
route.Run(":8085")
}
func getBookable(c *gin.Context) {
var b Booking
if err := c.ShouldBindWith(&b, binding.Query); err == nil {
c.JSON(http.StatusOK, gin.H{"message": "Booking dates are valid!"})
} else {
c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})
}
}import 有一点改动,没有加/v10,看了一下源文件是v10的,就去掉了
import "github.com/go-playground/validator"
然后运行
$ curl "http://127.0.0.1:8085/bookable?check_in=2021-04-02&check_out=2021-04-07"
{"message":"Booking dates are valid!"}
$ curl "http://127.0.0.1:8085/bookable?check_in=2021-04-09&check_out=2021-04-07"
{"error":"Key: 'Booking.CheckOut' Error:Field validation for 'CheckOut' failed on the 'gtfield' tag"}
$ curl "http://127.0.0.1:8085/bookable?check_in=2021-04-01&check_out=2021-04-07"
{"error":"Key: 'Booking.CheckIn' Error:Field validation for 'CheckIn' failed on the 'bookabledate' tag"}%能出来结果,可能是版之前的兼容性问题。先这么着吧。
type Booking struct
里把binding改成validate
