golang：读取smtp.SendMail

Question

多的错误响应

我使用这个代码：

err := smtp.SendMail(
    smtpHostPort, 
    auth, 
    sender, 
    []string{recipient}, 
    []byte(message), 
) 
if err != nil { 
    log.Printf("sendSmtp: failure: %q", strings.Split(err.Error(), "\n")) 
} 

然而，多行错误的反应似乎截断：

2013/02/06 11:54:41 sendSmtp: failure: ["530 5.5.1 Authentication Required. Learn more at"] 

我怎样才能得到充分的多错误响应？

Answer 2

错误不是多行字符串。

package main 

import (
    "errors" 
    "log" 
    "strings" 
) 

func main() { 
    err := errors.New("530 5.5.1 Authentication Required. Learn more at") 
    log.Printf("sendSmtp: failure: %q", strings.Split(err.Error(), "\n")) 
    err = errors.New("530 5.5.1 Authentication Required. Learn more at\nstackoverflow.com") 
    log.Printf("sendSmtp: failure: %q", strings.Split(err.Error(), "\n")) 
} 

输出：

2013/02/06 13:30:19 sendSmtp: failure: ["530 5.5.1 Authentication Required. Learn more at"] 
2013/02/06 13:30:19 sendSmtp: failure: ["530 5.5.1 Authentication Required. Learn more at" "stackoverflow.com"]
