封装发送邮件功能

使用的是PHPMailer包

//邮件发送
if (!function_exists('sendmail')) {
    function sendmail($address, $title, $body)
    {
        $mail = new \PHPMailer\PHPMailer\PHPMailer(true);
        try {
            $mail->SMTPDebug = 0;
            $mail->isSMTP();
            $mail->CharSet = "UTF-8";                     //utf-8;
            $mail->Encoding = "base64";
            $mail->Host = env('mail.host');
            $mail->SMTPAuth = true;
            $mail->Username = env('mail.username');
            $mail->Password = env('mail.password');
            $mail->SMTPSecure = env('mail.encryption');
            $mail->Port = env('mail.port');

            //Recipients
            $mail->setFrom(env('mail.from_address'), env('mail.from_name'));
            //接收人
            $mail->addAddress($address);
            //回复的时候回复给哪个邮箱 建议和发件人一致
            $mail->addReplyTo(env('mail.from_address'), 'info');
            //Content
            $mail->isHTML(true);
            //防止中文乱码
            $mail->Subject = "=?UTF-8?B?" . base64_encode($title) . "?=";
            $mail->Body = $body;
            $mail->AltBody = '您的邮箱客户端不支持显示HTML内容';

            $mail->send();
            return true;

        } catch (Exception $e) {
            return $e;
        }
    }

}

2.使用

sendmail('xxx@xx.xx', '系统通知', '<h1>你好啊</h1>');

3.使用think-queue消息队列发送邮件

//前面的注册逻辑省略...


//缓存key(此处可以替换为redis等nosql缓存产品)
//参数说明 
//参数1：缓存标志register_email_code_+用户注册入库时返回的主键id作为缓存key
//参数2：uuid当作缓存值进行缓存
//参数3：缓存过期时间（这里我从我的配置文件中读取，你可以直接设置值，单位：秒），24 * 60 * 60
cache("register_email_code_" . $user->id, $uuid, config('my.email_register.expire'));


            //异步发送邮箱
            //把需要的数据传递过去
            Queue::push(RegEmailActiveJob::class, [
                'user_id' => $user->id,
                //昵称
                'nickname' => $user->profile->nickname,
                //uuid
                'uuid' => $uuid,
                //发给谁
                'email' => $user->email
            ]);

生成RegEmailActiveJob异步任务

<?php


namespace app\job;



use think\queue\Job;

class RegEmailActiveJob
{
    public function fire(Job $job, $data)
    {

        $user_id = $data['user_id'];
        $nickname = $data['nickname'];
        $uuid = $data['uuid'];
        $email = $data['email'];

        $link = env('app.host') . '/validate/email?user_id=' . $user_id . '&code=' . $uuid;

        //smarty替换变量后返回html内容
        $html = app('smarty')->fetch('index/email/regEmailActive.tpl', compact('nickname', 'link'));

        //发送邮件
        sendmail($email, config('my.email_register.title'), $html);

        if ($job->attempts() > 3) {
            //通过这个方法可以检查这个任务已经重试了几次了
//            Log::info("超过三次");

        }


        //如果任务执行成功后 记得删除任务，不然这个任务会重复执行，直到达到最大重试次数后失败后，执行failed方法
        $job->delete();

        // 也可以重新发布这个任务
        //$job->release(0); //$delay为延迟时间

    }

    public function failed($data)
    {

        // ...任务达到最大重试次数后，失败了

    }


}

uuid生成方法

//生成uuid
if (!function_exists('uuid')) {
    function uuid($prefix = '')
    {
        $chars = md5(uniqid(mt_rand(), true));
        $uuid = substr($chars, 0, 8);
        $uuid .= substr($chars, 8, 4);
        $uuid .= substr($chars, 12, 4);
        $uuid .= substr($chars, 16, 4);
        $uuid .= substr($chars, 20, 12);
        return $prefix . $uuid;
    }
}

发送成功后用户点击连接的处理

验证成功后你可以直接登录，你也可以跳转回登录页，让用户登录

    //邮箱注册链接回调
    public function email(Request $request)
    {

        //接收参数
        $user_id = $request->get('user_id');
        $code = $request->get('code');


        if ($user_id === null || $code === null) {

            return $this->smarty->display('index/error/error.tpl', [
                'msg' => '激活地址非法',
                'code' => 500
            ]);

        }

        //判断缓存中取出来的是否和传递过来的是否相等
        if (cache('register_email_code_' . $user_id) != $code) {
            return $this->smarty->display('index/error/error.tpl', [
                'msg' => '激活地址已失效',
                'code' => 500
            ]);
        }


        //上面那一步过不来就等于是非法了，到这一步其实就已经可以直接更新状态了
        $user = User::with(['profile'])->find($user_id);

        $user->status = 1;

        $user->save();

        //让缓存失效
        cache('register_email_code_' . $user_id, null);

        //直接登录
        session('index_user', $user);
        return redirect((string)url('/'))->with('success', '登录成功');
    }
