有了監(jiān)控程序我們還需要有通知的功能，這里使用郵件通知
package main
import (
"fmt"
"net/smtp"
"strings"
)
//SendToMail 發(fā)送郵件
func SendToMail(user, password, host, to, subject, body, mailtype string) error {
hp := strings.Split(host, ":")
auth := smtp.PlainAuth("", user, password, hp[0])
sendTo := strings.Split(to, ";")
done := make(chan error, 1024)
var contentType string
if mailtype == "html" {
contentType = "Content-Type: text/" + mailtype + "; charset=UTF-8"
} else {
contentType = "Content-Type: text/plain" + "; charset=UTF-8"
}
go func() {
defer close(done)
for _, strTo := range sendTo {
msg := []byte("To: " + to + "\r\nFrom: " + user + "\r\nSubject: " + subject + "\r\n" + contentType + "\r\n\r\n" + body)
err := smtp.SendMail(host, auth, user, []string{strTo}, msg)
done <- err
}
}()
for i := 0; i < len(sendTo); i++ {
<-done
}
//fmt.Println(sendTo)
return nil
}
main func(){
user := "發(fā)郵件用的郵箱地址"
password := "發(fā)郵件用的郵箱密碼"
host := "smtp.exmail.qq.com:25"//smtp服務(wù)器地址，這里使用的是騰訊企業(yè)郵箱的smtp
to := "接收郵件的郵箱地址1;接收郵件的郵箱地址2"//可以使用;分隔，實(shí)現(xiàn)發(fā)送到多個(gè)郵箱
subject := "通知郵件"
body := "<html><head><tille>通知郵件</title></head><body><h3>通知郵件測試</h3></body></html>"
fmt.Println("sending email")
err := SendToMail(user, password, host, to, subject, body, "html")
if err != nil {
fmt.Println("Send mail error!")
fmt.Println(err)
} else {
fmt.Println("Send mail success!")
}
}
使用“net/smtp”包實(shí)現(xiàn)郵件發(fā)送功能，需要自備一個(gè)郵箱作為發(fā)件郵箱，最好使用大廠的郵箱作為發(fā)件郵箱，以免被識(shí)別為垃圾郵件拒收。
暫無評(píng)論，快來評(píng)論吧!
