Yii2 使用邮箱组件发送邮件

1.在Yii2配置文件中添加邮箱组件

        'mailer' => [
            'class' => 'yii\swiftmailer\Mailer',
            'transport' => [
                'class' => 'Swift_SmtpTransport',
                'host' => 'smtp.qq.com',
                'username' => '923258***@qq.com',
                'password' => 'zbxjaxyihfcabedc',    //第三方客户端登录授权码，需在邮箱中开启POP3/SMTP和IMAP/SMTP服务
                'port' => '25',
//                'port' => '465',
                'encryption' => 'tls',
//                'encryption' => 'ssl',
            ],
            'messageConfig' => [
                'charset' => 'UTF-8',
                'from' => ['923258***@qq.com' => 'admin']
            ],
        ],

2.调用邮箱接口发送邮件

public function actionMailer()
    {
        $mail = \YII::$app->mailer->compose();//加载模板这样写：$mail= Yii::$app->mailer->compose('view',['key'=>'value']);
        $mail->setTo("navioo@163.com");
        $mail->setSubject("邮件测试");
        $mail->setTextBody("textbody 25 ok?");//发布纯文字文本
        //$mail->setHtmlBody("htmlbody");//发布可以带html标签的文本
        if($mail->send()){
            echo "success";
        }else{
            echo "failure";
        }
        die();
    }
