我无法将mysql时间戳值输入到time.Time变量中

我正在尝试扫描一行,除mysql中的时间戳类型外,所有值均已成功扫描,我已经在使用dsn parseTime = true,这是我搜索到的问题之一,但无济于事

        type Tags struct {
            ID             int
            CreatedAt      time.Time `json:"created_at"`
        }
        func foo5() {
            http.HandleFunc("/tags/", bar5)
            http.ListenAndServe(":8080", nil)
        }

        func bar5(w http.ResponseWriter, r *http.Request) {
            db, err := sql.Open("mysql", "root:*******@/catalogue_service?parseTime=true")
            if err != nil {
            fmt.Println("error opening")
            }
            v, _ := strconv.Atoi(path.Base(r.URL.Path))
            row := db.QueryRow("select * from tags where id = ?", v)
            var myRow Tags
            row.Scan(&myRow.ID, &myRow.CreatedAt)
            fmt.Println(myRow)
        }

int和字符串值正确显示,但CreatedAt打印    0001-01-01 00:00:00 +0000 UTC 而不是实际值

您是否按照以下方式注册了mysql驱动程序?

Dockerfile

在此处查看用法:

错误已由我自己解决, 表中存在Scan无法处理的空值,因此我根据字段在结构中使用了sql.NULLString或mysql.NULLTime类型
