英文:
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：
func main() {
to := "first.last@acme.com"
from := "me@acme.com"
password := "myKey"
subject := "Subject Here"
msg := "Message here"
emailTemplate := `To: %s
Subject: %s
%s
`
body := fmt.Sprintf(emailTemplate, to, subject, msg)
auth := smtp.PlainAuth("", from, password, "smtp.office365.com")
err := smtp.SendMail(
"smtp.office365.com:587",
auth,
from,
[]string{to},
[]byte(body),
)
if err != nil {
log.Fatal(err)
}
}
这段代码返回以下错误信息：
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：
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:
func main() {
to := "first.last@acme.com"
from := "me@acme.com"
password := "myKey"
subject := "Subject Here"
msg := "Message here"
emailTemplate := `To: %s
Subject: %s
%s
`
body := fmt.Sprintf(emailTemplate, to, subject, msg)
auth := smtp.PlainAuth("", from, password, "smtp.office365.com")
err := smtp.SendMail(
"smtp.office365.com:587",
auth,
from,
[]string{to},
[]byte(body),
)
if err != nil {
log.Fatal(err)
}
}
This code returns:
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:
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：
type loginAuth struct {
username, password string
}
// LoginAuth用于smtp登录认证
func LoginAuth(username, password string) smtp.Auth {
return &loginAuth{username, password}
}
func (a *loginAuth) Start(server *smtp.ServerInfo) (string, []byte, error) {
return "LOGIN", []byte(a.username), nil
}
func (a *loginAuth) Next(fromServer []byte, more bool) ([]byte, error) {
if more {
switch string(fromServer) {
case "Username:":
return []byte(a.username), nil
case "Password:":
return []byte(a.password), nil
default:
return nil, errors.New("未知的服务器返回")
}
}
return nil, nil
}
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:
type loginAuth struct {
username, password string
}
// LoginAuth is used for smtp login auth
func LoginAuth(username, password string) smtp.Auth {
return &loginAuth{username, password}
}
func (a *loginAuth) Start(server *smtp.ServerInfo) (string, []byte, error) {
return "LOGIN", []byte(a.username), nil
}
func (a *loginAuth) Next(fromServer []byte, more bool) ([]byte, error) {
if more {
switch string(fromServer) {
case "Username:":
return []byte(a.username), nil
case "Password:":
return []byte(a.password), nil
default:
return nil, errors.New("Unknown from server")
}
}
return nil, nil
}
Replace this auth implementation with the stmp.PlainAuth from Golang lib and it should work accordingly.
