【问题描述】：

从 CakePHP 3 升级到 4 后，我在使用 Mailer 时遇到问题。这是我的配置的相关部分：

<?php

return [
    'EmailTransport' => [
        'default' => [
            'className' => 'Mail',
            'host' => 'localhost',
            'port' => 25,
            'timeout' => 30,
            'username' => 'user',
            'password' => 'password',
            'client' => null,
            'tls' => null,
            'url' => env('EMAIL_TRANSPORT_DEFAULT_URL', null),
        ],
        'cronjob' => [
            'className' => 'Mail',
        ],
        'accounts' => [
            'className' => 'Mail',
        ],
    ],

    'Email' => [
        'default' => [
            'transport' => 'default',
            'from' => 'you@localhost',
        ],
        'cronjob' => [
            'transport' => 'cronjob',
            'from' => 'cronjob@foobar.com',
        ],
        'accounts' => [
            'transport' => 'accounts',
            'from' => 'accounts@foobar.com',
        ],
    ],
];

这是导致错误的 sn-p：

    private function sendActivationEmail(User $user)
    {
        $url = Router::url([
            'prefix' => 'Admin',
            'plugin' => 'UserManager',
            'controller' => 'Users',
            'action' => 'activate',
            $user->username,
            $user->activation_key,
        ], true);

        debug(Configure::read('EmailTransport'));
        debug(Configure::read('Email'));

        $mailer = new Mailer('accounts');
        $mailer->setFrom(['accounts@foobar.com' => 'Foobar Website Manager'])
            ->setTo($user->email, $user->fullName)
            ->setSubject('Please activate your account')
            ->setEmailFormat('html')
            ->setViewVars(compact('url', 'user'))
            ->viewBuilder()
                ->setTemplate('UserManager.register');

        return $mailer->deliver();
    }

错误是Unknown email configuration "accounts".，抛出

两个debug函数的输出如下：

/vendor/plugins/usermanager/src/Model/Table/UsersTable.php (line 72)
[
    'default' => [
        'className' => 'Mail'
    ],
    'cronjob' => [
        'className' => 'Mail'
    ],
    'accounts' => [
        'className' => 'Mail'
    ]
]

/vendor/plugins/usermanager/src/Model/Table/UsersTable.php (line 73)
[
    'default' => [
        'transport' => 'default',
        'from' => 'something@foobar.com'
    ],
    'cronjob' => [
        'transport' => 'cronjob',
        'from' => 'cronjob@foobar.com'
    ],
    'accounts' => [
        'transport' => 'accounts',
        'from' => 'accounts@foobar.com'
    ]
]

看来accounts 键似乎存在于邮件配置中，那为什么会出现此错误？

【解决方案1】：

确保你已经相应地升级了你的bootstrap.php，特别是关于EmailTransport和Email的使用方式，如果我没记错的话，这是在CakePHP 3.7和4.1中引入的：

TransportFactory::setConfig(Configure::consume('EmailTransport'));
Mailer::setConfig(Configure::consume('Email'));
