如何阅读config / app.php中定义的“电子邮件”选项？

Question

I'm trying to read the email options defined in config/app.php , using Configure::read('Email'); , but it returns null . Other options can be read just fine using Configure::read(<options name>) .

I think reading the Email options is being blocked somehow. How can I read the Email options from the configuration defined in config/app.php using Configure::read() ? Do I maybe have to read them in a different way?

Answer 1

Comsumed configuration is being deleted

Some configuration is being "consumed" at some point, by default that currently is Cache , Datasources , EmailTransport , Email , Log , and Security.salt , see your applications config/bootstrap.php file.

https://github.com/cakephp/app/blob/3.2.4/config/bootstrap.php#L146-L151

Consuming keys results in them being deleted after they have been read, so after that point in your bootstrap there will be no Email config anymore, and consequently you'll receive null when trying to read it.

Retrieve the configuration from the consumers

If you want to access such configuration at a later point, then you should access it via the classes that consumed it, in your case the Email class, ie read it via

\Cake\Network\Email\Email::config() // (CakePHP < 3.1)

or

\Cake\Mailer\Email::config() // (CakePHP >= 3.1)

depending on your CakePHP version.

Answer 2

在CakePHP版本> 3.4中，您必须使用

\Cake\Mailer\Email::getConfigTransport('smtp');
