Connecting to Exchange with Golang

问题

如何使用Go连接到Exchange服务器？我已经尝试了以下代码：

  1. func main() {
  2.     to := "first.last@acme.com"
  3.     from := "me@acme.com"
  4.     password := "myKey"
  5.     subject := "Subject Here"
  6.     msg := "Message here"
  8.     emailTemplate := `To: %s
  9.     Subject: %s
  11.     %s
  12.     `
  13.     body := fmt.Sprintf(emailTemplate, to, subject, msg)
  14.     auth := smtp.PlainAuth("", from, password, "smtp.office365.com")
  15.     err := smtp.SendMail(
  16.         "smtp.office365.com:587",
  17.         auth,
  18.         from,
  19.         []string{to},
  20.         []byte(body),
  21.     )
  22.     if err != nil {
  23.         log.Fatal(err)
  24.     }
  25. }

这段代码返回以下错误信息：

  1. 504 5.7.4 Unrecognized authentication type

我正在将Python/Django代码移植过来，它有一个设置项需要声明：

  1. EMAIL_USE_TLS = True

在Go中可能有类似的设置吗？

How do I connect with Exchange server with Go? I have tried:

  1. func main() {
  3. to := "first.last@acme.com"
  4. from := "me@acme.com"
  5. password := "myKey"
  6. subject := "Subject Here"
  7. msg := "Message here"
  9. emailTemplate := `To: %s
  10. Subject: %s
  12. %s
  13. `
  14. body := fmt.Sprintf(emailTemplate, to, subject, msg)
  15. auth := smtp.PlainAuth("", from, password, "smtp.office365.com")
  16. err := smtp.SendMail(
  17. 	"smtp.office365.com:587",
  18. 	auth,
  19. 	from,
  20. 	[]string{to},
  21. 	[]byte(body),
  22. )
  23. if err != nil {
  24. 	log.Fatal(err)
  25. }
  26. }

This code returns:

  1. 504 5.7.4 Unrecognized authentication type

I'm porting over Python/Django code, and it has a setting where I mark have to declare:

  1. EMAIL_USE_TLS = True

Perhaps something similar in Go?

Office在2017年8月之后不再支持AUTH PLAIN身份验证。参考。但是，它支持AUTH LOGIN。AUTH LOGIN没有原生的Golang实现，但下面是一个可用的实现：

  1. type loginAuth struct {
  2.     username, password string
  3. }
  5. // LoginAuth用于smtp登录认证
  6. func LoginAuth(username, password string) smtp.Auth {
  7.     return &loginAuth{username, password}
  8. }
  10. func (a *loginAuth) Start(server *smtp.ServerInfo) (string, []byte, error) {
  11.     return "LOGIN", []byte(a.username), nil
  12. }
  14. func (a *loginAuth) Next(fromServer []byte, more bool) ([]byte, error) {
  15.     if more {
  16.         switch string(fromServer) {
  17.         case "Username:":
  18.             return []byte(a.username), nil
  19.         case "Password:":
  20.             return []byte(a.password), nil
  21.         default:
  22.             return nil, errors.New("未知的服务器返回")
  23.         }
  24.     }
  25.     return nil, nil
  26. }

将此身份验证实现替换为Golang库中的stmp.PlainAuth，应该可以正常工作。

英文:

Office does not support AUTH PLAIN after August 2017. Ref. However, it does support AUTH LOGIN. AUTH LOGIN does not have a native Golang implementation but here is a working one:

  1. type loginAuth struct {
  2. 	username, password string
  3. }
  5. // LoginAuth is used for smtp login auth
  6. func LoginAuth(username, password string) smtp.Auth {
  7. 	return &loginAuth{username, password}
  8. }
  10. func (a *loginAuth) Start(server *smtp.ServerInfo) (string, []byte, error) {
  11. 	return "LOGIN", []byte(a.username), nil
  12. }
  14. func (a *loginAuth) Next(fromServer []byte, more bool) ([]byte, error) {
  15. 	if more {
  16. 		switch string(fromServer) {
  17. 		case "Username:":
  18. 			return []byte(a.username), nil
  19. 		case "Password:":
  20. 			return []byte(a.password), nil
  21. 		default:
  22. 			return nil, errors.New("Unknown from server")
  23. 		}
  24. 	}
  25. 	return nil, nil
  26. }

Replace this auth implementation with the stmp.PlainAuth from Golang lib and it should work accordingly.
