我得到错误：

cannot use U.Created_date (type time.Time) as type string in array element

可以将time.Time转换成字符串吗？

type UseRSSession struct {
    Userid int
    Timestamp time.Time
    Created_date time.Time
}

type Users struct {
    Name string
    Email string
    Country string
    Created_date time.Time
    Id int
    Hash string
    IP string
}

–

var usersArray = [][]string{}

rows,err := db.Query("SELECT u.id,u.hash,u.name,u.email,u.country,u.IP,u.created_date,us.timestamp,us.created_date FROM useRSSession AS us LEFT JOIN users AS u ON u.id = us.userid WHERE us.timestamp + interval 30 minute >= now()")

U := Users{}
US := UseRSSession{}

for rows.Next() {
    err = rows.Scan(&U.Id,&U.Hash,&U.Name,&U.Email,&U.Country,&U.IP,&U.Created_date,&US.Timestamp,&US.Created_date)
    checkErr(err)

    userid_string := strconv.Itoa(U.Id)
    user := []string{userid_string,U.Hash,U.Name,U.Email,U.Country,U.IP,U.Created_date,US.Timestamp,US.Created_date}
    // -------------
    // ^ this is where the error occurs
    // cannot use U.Created_date (type time.Time) as type string in array element (for US.Created_date and US.Timestamp aswell)
    // -------------

    usersArray = append(usersArray,user)
    log.Print("usersArray: ",usersArray)
}

编辑

我添加了以下内容.现在工作,谢谢.

userCreatedDate := U.Created_date.Format("2006-01-02 15:04:05")
userSessionCreatedDate := US.Created_date.Format("2006-01-02 15:04:05")
userSessionTimestamp := US.Timestamp.Format("2006-01-02 15:04:05")
