go - 无法使用validator.v2 golang进行验证

Question

我在用gin验证程序验证字段时遇到麻烦。
我每次在struct上添加验证时都会返回的错误
我在这里做错了什么
图式

package entity

type User struct {
    Username         string `json:"username" binding:"min=2,required"`
    Email            string `json:"email" binding:"required,email" validate:"email"`
    Password         string `json:"password" binding:"min=8,max=32,alphanum"`
    ConfirmPassword  string `json:"confirm_password" binding:"eqfield=Password,required"`
}

我正在尝试添加验证中间件

package validations

import (
    "github.com/bihire/ikaze_server_app/entity"
    "net/http"
    "github.com/gin-gonic/gin"
    "gopkg.in/validator.v2"
)


func SignupValidator(ctx *gin.Context) {
    var user entity.User
    if err := validator.Validate(&user); err != nil {
        ctx.JSON(http.StatusBadRequest, gin.H{
            "error": err.Error(),
        })
    }
}

我回到每个地方的错误，我在架构上添加了验证

{
    "error": "Email: unknown tag"
}{
    "username": "this the first video description",
    "email": "h",
    "password": "password",
    "confirm_password": "password"
}

当前软件包中没有“电子邮件”验证程序:https://github.com/go-validator/validator/tree/v2
https://github.com/go-playground/validator中有一个“电子邮件”验证器
