go语言发送邮件,可以使用smtp包,两个关键函数:
func PlainAuth(identity, username, password, host string) Auth
func SendMail(addr string, a Auth, from string, to []string, msg []byte) error
刚开始玩的时候,很好奇邮件的title是怎么设置进去的,毕竟从代码没看见有setTitle。后来发现是解析msg获取标题、发件人、收件人、邮件格式、邮件内容等;因此msg需要按一定格式写:To: xxx From:xxxx Subject: xxxx Content-Type:text/html; charset=UTF-8 [邮件内容]
func (this *TestController) SendMail(){ subject := "This is golang test email..." user := "xxxxx@163.com" to := []string {"xxxxx@163.com"} nickname := "dyao" content := "mail body....." contentType := "Content-Type: text/html; charset=UTF-8" msg := []byte("To: " + strings.Join(to, ",") + " From: " + nickname + "<" + user + "> Subject: " + subject + " " + contentType + " " + content) auth := smtp.PlainAuth( "", user, "testpassword", "smtp.163.com", ) err := smtp.SendMail( "smtp.163.com:25", auth, user, to, []byte(msg), ) if err != nil{ log.Fatal(err) }else { log.Printf("Mail send: %s", msg) } }

163邮箱,把发送的邮件当垃圾拦截了,今天打算换qq邮箱,被坑到怀疑人生....
密码,不是qq登陆密码,是授权码!授权码!授权码!授权码!
授权码,在qq邮箱设置里面获取,会发送到手机上
