CakePHP 邮件程序“未知的电子邮件配置”错误

问题描述

从 CakePHP 3 升级到 4 后，我在使用 Mailer 时遇到了问题。 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' => '[e-mail]','accounts' => [
            'transport' => 'accounts','from' => '[e-mail]',];

这是导致错误的代码段：

    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');
        $mailer->setFrom(['[e-mail]' => 'Foobar Website Manager'])
            ->setTo($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' => '[e-mail]'
    ],'cronjob' => [
        'transport' => 'cronjob','from' => '[e-mail]'
    ],'accounts' => [
        'transport' => 'accounts','from' => '[e-mail]'
    ]
]

所以邮件配置中似乎存在 accounts 键，那为什么我会收到此错误？

解决方法

请确保您在此过程中相应地升级了 bootstrap.php，特别是关于 EmailTransport 和 Email 的消耗方式，这是在 CakePHP 3.7 和 4.1 中引入的，如果我没看错：

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