• [x] How to take the fields in the structure that are converted to json when translating. For example, in the code I provided, I want to get phone instead of Phone.

Package version eg. v9, v10:

v9

Issue, Question or Enhancement:

I want to use an uppercase Phone in the structure and a lowercase phone when an error message is returned

Code sample, to showcase or reproduce:

// core/validator/user_validator.go

package validator

import (
    "fmt"
    "github.com/gin-gonic/gin"
    ut "github.com/go-playground/universal-translator"
    "gopkg.in/go-playground/validator.v9"
)

type UserLoginRequest struct {
    //Username string `json:"username" binding:"required,min=4,max=20"`
    //Phone   string  `json:"phone" form:"phone" validate:"required,email"`
    Phone    string  `json:"phone" form:"phone" validate:"required"`
    Password string  `json:"password" form:"password" validate:"required,min=6"`
}

func ValidateUserLogin(c *gin.Context) (*UserLoginRequest, error) {
    var request UserLoginRequest
    utTrans := c.Value("Trans").(ut.Translator)

    Validate, _ := c.Get("Validate")
    validatorInstance, _ := Validate.(*validator.Validate)

    if err := c.ShouldBindJSON(&request); err != nil {
        return nil,err
    }

    //自定义错误语句
    //validatorInstance.RegisterTranslation("required", utTrans, func(ut ut.Translator) error {
    //  return ut.Add("required", "{0} 哈哈哈!", true) // see universal-translator for details
    //}, func(ut ut.Translator, fe validator.FieldError) string {
    //  t, _ := ut.T("required", fe.Field())
    //  return t
    //})

    //validatorInstance.RegisterTranslation(
    //  "email",
    //  utTrans,
    //  func(ut ut.Translator) error {
    //      return ut.Add("email", "{0}格式不正确", true)
    //  },
    //  func(ut ut.Translator, fe validator.FieldError) string {
    //      t, _ := ut.T("email", fe.Field())
    //      return t
    //  },
    //)

    // 进行进一步的验证
    err := validatorInstance.Struct(request) //这里的err是未翻译之前的
    if  err != nil {
        errs := err.(validator.ValidationErrors)
        var sliceErrs []string
        for _, e := range errs {
            sliceErrs = append(sliceErrs, e.Translate(utTrans))
        }
        return nil,fmt.Errorf(sliceErrs[0])
    }

    return &request,nil
}
