How to reproduce

type BaseController struct {
    Ctx  *gin.Context
}

type ClassifyRestApi struct {
    BaseController
}

func (bc *ClassifyRestApi) GetList(ctx *gin.Context) {
    bc.Ctx = ctx
    var ProList []models.Product
    common.DB.Where("status=?", 1).Order("sort desc").Find(& ProList)
    bc.Ctx.JSON(http.StatusOK, gin.H{
        "Code": "code",
        "Data": ProList,
    })
}
