用go语言发送一封邮件

二、实现源代码

package main
import (
    "net/smtp"
    "fmt"
    "strings"
)

/*
 *  user : example@example.com login smtp server user
 *  password: xxxxx login smtp server password
 *  host: smtp.example.com:port   smtp.163.com:25
 *  to: example@example.com;example1@163.com;example2@sina.com.cn;...
 *  subject:The subject of mail
 *  body: The content of mail
 *  mailtyoe: mail type html or text
 */

func SendMail(user, password, host, to, subject, body, mailtype string) error{
    hp := strings.Split(host, ":")
    auth := smtp.PlainAuth("", user, password, hp[0])
    var content_type string
    if mailtype == "html" {
        content_type = "Content-Type: text/"+ mailtype + "; charset=UTF-8"
    }else{
        content_type = "Content-Type: text/plain" + "; charset=UTF-8"
    }

    msg := []byte("To: " + to + "rnFrom: " + user + "<"+ user +">rnSubject: " + subject + "rn" + content_type + "rnrn" + body)
    send_to := strings.Split(to, ";")
    err := smtp.SendMail(host, auth, user, send_to, msg)
    return err
}

func main() {
    user := "此处填写qq邮箱账号"
    password := "此处填写qq邮箱授权码"
    host := "smtp.qq.com:587"
    to := "18720081236m@sina.cn"
    subject := "Test send email by golang"

    body := `
`
    fmt.Println("send email")
    err := SendMail(user, password, host, to, subject, body, "text")
    if err != nil {
        fmt.Println("send mail error!")
        fmt.Println(err)
    }else{
        fmt.Println("send mail success!")
    }

}
