Saya mencoba menambahkan beberapa nilai dari database saya ke a []string
dalam Go. Beberapa di antaranya adalah stempel waktu.
Saya mendapatkan kesalahan:
tidak bisa menggunakan U.Created_date (type time.Time) sebagai tipe string dalam elemen array
Bisakah saya mengonversi time.Time
ke string
?
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)
}
EDIT
Saya menambahkan yang berikut ini. Ini berfungsi sekarang, terima kasih.
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")
