Go 언어의 시간 기능을 사용하여 일정 달력을 생성하고 이메일 알림을 생성하는 방법은 무엇입니까?

package main import ( "fmt" "time" ) type Event struct { Name string StartTime time.Time EndTime time.Time } func main() { now := time.Now() events := []Event{ {Name: "会议1", StartTime: time.Date(now.Year(), now.Month(), now.Day(), 9, 0, 0, 0, now.Location()), EndTime: time.Date(now.Year(), now.Month(), now.Day(), 11, 0, 0, 0, now.Location())}, {Name: "会议2", StartTime: time.Date(now.Year(), now.Month(), now.Day(), 14, 0, 0, 0, now.Location()), EndTime: time.Date(now.Year(), now.Month(), now.Day(), 16, 0, 0, 0, now.Location())}, } for _, event := range events { if now.After(event.StartTime) && now.Before(event.EndTime) { fmt.Printf("今天有一个重要事件：%s，在%s至%s期间 ", event.Name, event.StartTime.Format("15:04"), event.EndTime.Format("15:04")) } } }

package main import ( "fmt" "net/smtp" "time" ) type Event struct { Name string StartTime time.Time EndTime time.Time Recipients []string } func main() { generateCalendar() sendEmail() } func generateCalendar() { // 生成日程日历的代码，与上一步相同 // ... } func sendEmail() { auth := smtp.PlainAuth("", "sender@example.com", "password", "smtp.example.com") now := time.Now() events := []Event{ {Name: "会议1", StartTime: time.Date(now.Year(), now.Month(), now.Day(), 9, 0, 0, 0, now.Location()), EndTime: time.Date(now.Year(), now.Month(), now.Day(), 11, 0, 0, 0, now.Location()), Recipients: []string{"participant1@example.com", "participant2@example.com"}}, {Name: "会议2", StartTime: time.Date(now.Year(), now.Month(), now.Day(), 14, 0, 0, 0, now.Location()), EndTime: time.Date(now.Year(), now.Month(), now.Day(), 16, 0, 0, 0, now.Location()), Recipients: []string{"participant3@example.com"}}, } for _, event := range events { if now.After(event.StartTime) && now.Before(event.EndTime) { message := fmt.Sprintf("今天有一个重要事件：%s，在%s至%s期间", event.Name, event.StartTime.Format("15:04"), event.EndTime.Format("15:04")) subject := fmt.Sprintf("事件提醒：%s", event.Name) recipients := event.Recipients body := fmt.Sprintf("To: %s Subject: %s %s", recipients, subject, message) err := smtp.SendMail("smtp.example.com:25", auth, "sender@example.com", recipients, []byte(body)) if err != nil { fmt.Println("发送邮件失败：", err) continue } fmt.Printf("已发送邮件提醒：%s ", event.Name) } } }
