golang：send mail using smtp package

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\\r\\nFrom:xxxx\\r\\nSubject: xxxx\\r\\nContent-Type:text/html; charset=UTF-8\\r\\n\\r\\n\[邮件内容\]

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, ",") + "\r\nFrom: " + nickname + "<" + user + ">\r\nSubject: " + subject + "\r\n" + contentType + "\r\n\r\n" + 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:\r\n%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
