需要设置全局报警设置需要使用stmp 邮件代理，这里使用yii2 2.0.12

我使用的是qq邮箱为例

账号：qq号@qq.com

密码：邮箱授权码，具体获取在账号设置中，可以进行短信重置授权码

port:587

其中 EmailTarget 有demo

配置实例=》comm->main-local.php

'components' => [     'mailer' => [         'class' => 'yii\swiftmailer\Mailer',         'viewPath' => '@common/mail',         // send all mails to a file by default. You have to set         // 'useFileTransport' to false and configure a transport         // for the mailer to send real emails.         'useFileTransport' => false,         'transport' => [             'class' => 'Swift_SmtpTransport',             'host' => 'smtp.qq.com',             'username' => '******@qq.com',             'password' => '******',             'port' => '587',             'encryption' => 'tls',         ],         'messageConfig' => [             'charset' => 'UTF-8',             'from' => ['******@qq.com' => '****授权码**']         ],     ],     'log' => [         'targets' => [             [                 'class' => 'yii\log\EmailTarget',                 'mailer' => 'mailer',                 'levels' => ['error', 'warning'],                 'message' => [                     'from' => ['*****发送者邮箱*****'],

'to' => ['*****接收者邮箱*****', '*****接收者邮箱*****'],

'subject' => '全局异常捕获',                 ],             ],         ],     ], ],
