php通过smtp服务模拟客户端发送email

刚进新公司项目用php开发的一个移动app商城项目，当时是需要做一个用户注册账号时，需要用户在填写邮箱时，后台获取到填写的邮箱，生成一个四位数的验证码，发送到该邮箱，邮箱发送成功后，再将这个验证码返回给前台，前台页面拿到这个验证码后会去判断用户输入的这个验证码是否是后台发送的这个验证码。目的就是为了防止用户注册时候胡乱填写邮箱

好吧上代码。这里主要注意的是2个地方，1个是发件箱的内容和标题的编码格式。我是直接在它方法开始时直接设置编码格式为utf-8，还有一个地方就是设置smtp密码时，无论你是163还是qq邮箱作为发件人，必须登陆邮箱里面开启smtp服务，现在的smtp服务都需要开启客户端的授权码，所以你在填写smtp服务器密码时，必须是填写客户端授权码，而不是你的密码

qq邮箱开启smtp服务的地方，点击开启，qq邮箱会跟你一个客户端的授权码，记得拿这个授权码作为登陆密码就ok了

我试过用163新注册的账号，开通smtp服务发送邮件，但是无论怎么样都没有成功，一直提示我身份证验证错误，换成邮箱登陆密码也没用，后面试着用自己以前的账号发送一下就成功了，所以基本排除了代码的问题

//发送邮件和生成验证码
public function emailVlidateAction(){
    header("Content-Type: text/html;charset=utf-8");
    $email = $this->params()->fromQuery('email','[email protected]');

    if($email){
        //生成四位数随机验证码
        $token =  rand(1000,9999);
        //发送邮件
        $isSend = $this->smtpService($email,$token);
        //返回给前端验证码
        if($isSend === true){
            return new JsonModel(['status'=>200,'message'=>'请求成功！','data'=>$token]);
        }else{
            return new JsonModel(['status'=>202,'message'=>'邮件发送失败，请稍后再试！']);
        }
    }else{
        echo "用户email不能为空";
    }
}

public function smtpService($email,$token){

     $MailPort = 25; //SMTP服务端口
     $MailServer = "smtp.qq.com";
     $smtpMail = "[email protected]"; //SMTP邮箱账号
     $smtpuser = "xxxx"; //SMTP服务器账号
     $smtppass = "xxxx"; //SMTP服务器密码，除非是老版本注册的邮箱，否则现在申请的都需要用客户端授权码作为密码！！！

    //创建一个smtp服务对象, true是对发件人身份证验证
    $smtp = new Smtp($MailServer, $MailPort, $smtpuser, $smtppass, true);

    $smtp->debug = false;
    //设置请求内容格式
    $mailType = "HTML";
    //收件人邮箱
    $email = $email;
    //标题
    $emailTitle = "邮箱验证码";
    $emailBody = ""."亲爱的用户<br/>您的邮箱验证码是：".$token."<br/>如非本人发送的请求，请忽略此邮件.<br/>";
    // 收件人邮箱
    // 发件人邮箱
    // 邮箱标题
    // 邮箱内容
    // 邮件内容内型如:text 、:HTML
    return $smtp->sendmail($email, $smtpMail, $emailTitle, $emailBody, $mailType);
}
