1. 发送邮件包
package myMail
import (
"crypto/tls"
"fmt"
"github.com/go-admin-team/go-admin-core/sdk/config"
ext "go-admin/config"
"net/smtp"
"strings"
"time"
)
type MyEmail struct{
Host string
Port string
AuthUser string
AuthPass string
}
func (e *MyEmail)SendEmail(mailTo string, subject string, body string) (bool, error) {
//这里是从配置文件读邮件服务器配置信息
cfg, _ := config.ExtendConfig.(*ext.Extend)
emailCfg := cfg.Emailcfg
//没有配置文件直接赋值就行了
smtpHost := emailCfg.Host
smtpPort := emailCfg.Port
smtpUser := emailCfg.Authuser
smtpPass := emailCfg.Authpass
toSendList := mailTo
t := time.Now()
year,month,day := t.Date()
curTime := fmt.Sprintf("%d-%d-%d %d:%d",year,month,day,t.Hour(),t.Minute())
auth := smtp.PlainAuth("", smtpUser,smtpPass,smtpHost)
to := strings.Split(toSendList,",")
header := make(map[string]string)
header["From"] = smtpUser
header["To"] = mailTo
header["Date"] = curTime
header["Subject"] = subject
header["Content-Type"] = "text/html;charset=UTF-8"
msg := ""
for k,v := range header{
msg += fmt.Sprintf("%s:%s\r\n",k,v)
}
msg += "\r\n"+body
conn,err := tls.Dial("tcp",smtpHost+":"+smtpPort,nil)
if err != nil {
HandleWarning(err)
}
co,err := smtp.NewClient(conn,smtpHost)
if err != nil {
HandleWarning(err)
}
defer co.Close()
if auth != nil {
if ok,_ := co.Extension("AUTH");ok {
if err = co.Auth(auth);err != nil {
HandleError(err)
}
}
}
if err = co.Mail(smtpUser); err != nil {
HandleError(err)
}
for _,addr := range to {
if err = co.Rcpt(addr); err != nil {
HandleWarning(err)
}
}
w,err := co.Data()
if err != nil {
HandleWarning(err)
}
_,err = w.Write([]byte(msg))
if err != nil {
HandleWarning(err)
}
err = w.Close()
if err != nil {
HandleWarning(err)
}
co.Quit()
return true,nil
}
func HandleWarning(err error) {
//怎么处理警告可以在这里定义
}
func HandleError(err error) {
//怎么处理错误可以在这里定义
}
2. 使用
func sendReviewMail(mailInfo MailInfo) (b bool,err error){
subject := mailInfo.PrjNmEn + "项目 服务器申请"
body := mailInfo.PrjNmEn + "项目，服务器申请已提交，请尽快审批"
mailTo := "liubei-cto@xxx.com.cn"
email := myMail.MyEmail{}
b,err = email.SendEmail(mailTo,subject,body)
if err != nil {
return false,err
}
return b,nil
}
