    <div class="register-buttons">
        <button type="submit" class="btn btn-info btn-block btn-lg">Sign Up</button>
    </div>
</form>

Gin路由

router.GET("/register",auth.ShowRegistrationForm)
router.POST("/register",auth.Register)

Form struct

type RegisterForm struct {
    Name                 string `form:"name" binding:"required"`
    Email                string `form:"email" binding:"required"`
    Password             string `form:"password" binding:"required"`
    PasswordConfirmation string `from:"password_confirmation" binding:"required"`
}

Gin Controller

func Register(c *gin.Context) {
    var data RegisterForm
    if err := c.ShouldBind(&data); err != nil {
        c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})
        return
    }

    c.JSON(http.StatusOK, gin.H{
        "data": data,
    })
}

报错信息

{
    "error": "Key: 'RegisterForm.PasswordConfirmation' Error:Field validation for 'PasswordConfirmation' failed on the 'required' tag"
}

有人遇到这个问题吗？
