CakePHP 3 error for sending email using gmail

Question

I am trying to send an email confirmation using Gmail, but I am getting this error:

stream_socket_client (): SSL operation failed with code 1. OpenSSL Error messages: error: 14090086: SSL routines: SSL3_GET_SERVER_CERTIFICATE: certificate verification failed stream_socket_client (): Cryptography could not be enabled stream_socket_client (): cannot connect to ssl: // smtp .gmail.com: 465 (Unknown error)

I followed the Transport setup guide.

Email::configTransport('gmail', [ 'host' => 'ssl://smtp.gmail.com', //'host' => 'smtp.gmail.com', 'port' => 465, 'username' => ' [e-mail] ', 'password' => 'password', 'className' => 'Smtp', 'log'=>true, //'tls' => true ]); $correo = new Email(); $correo ->transport('gmail') ->template('registro_exito') ->emailFormat('html') ->to(' [e-mail] ') ->from(' [e-mail] ') ->viewVars([ 'nombre_sitio_secundario'=>$nombre_sitio_secundario, 'usuario_id'=>$usuario_id, 'token'=>$token ]) ->send(); 

And this is the complete error log:

 2015-09-24 20:09:39 Error: [Cake\Network\Exception\SocketException] stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed stream_socket_client(): Failed to enable crypto stream_socket_client(): unable to connect to ssl://smtp.gmail.com:465 (Unknown error) Request URL: /faindit/usuarios/registro Stack Trace: #0 C:\xampp\htdocs\faindit\vendor\cakephp\cakephp\src\Network\Email\SmtpTransport.php(204): Cake\Network\Socket->connect() #1 C:\xampp\htdocs\faindit\vendor\cakephp\cakephp\src\Network\Email\SmtpTransport.php(159): Cake\Network\Email\SmtpTransport->_connect() #2 C:\xampp\htdocs\faindit\vendor\cakephp\cakephp\src\Network\Email\Email.php(1301): Cake\Network\Email\SmtpTransport->send(Object(Cake\Network\Email\Email)) #3 C:\xampp\htdocs\faindit\src\Controller\Component\CorreoComponent.php(65): Cake\Network\Email\Email->send() #4 C:\xampp\htdocs\faindit\src\Controller\UsuariosController.php(14): App\Controller\Component\CorreoComponent->registroExito(1, ' something@gm...

It is worth mentioning that openssl es is enabled on php, and I also enabled "access for less secure applications" in Gmail configurations.

Thanks for the help!

Answer 1

Ok, I found a "mistake". Actually, the code is in order, the problem is OpenSSL in php 5.6, which checks every encrypted connection by default, BUT my local Lampp does not take into account with the ssl certificate, and this leads to an error.

The solution is to avoid validation, so the configTransport code will look like this:

 Email::configTransport('gmail', [ 'host' => 'ssl://smtp.gmail.com', 'port' => 465, 'username' => ' [e-mail] ', 'password' => 'password', 'className' => 'Smtp', 'log' => true, 'context' => [ 'ssl' => [ 'verify_peer' => false, 'verify_peer_name' => false, 'allow_self_signed' => true ] ] ]); 

I took the response of PHPMailer as a reference, but it was a little difficult to find out how to apply it to Cakephp3.

Hope this information is helpful to someone else.

  Send a verification email using gmail in CakePhp 3 Follow these steps to send verification code using gmail 1. open your your project/config/app.php 2. In your app.php, replace(hide) this code 'EmailTransport' => [ 'default' => [ 'className' => 'Mail', // The following keys are used in SMTP transports 'host' => 'localhost', 'port' => 25, 'timeout' => 30, 'username' => 'user', 'password' => 'secret', 'client' => null, 'tls' => null, 'url' => env('EMAIL_TRANSPORT_DEFAULT_URL', null), ], write this code in your app.php 'EmailTransport' => [ 'default' => [ 'className' => 'Mail', // The following keys are used in SMTP transports 'host' => 'localhost', 'port' => 25, 'timeout' => 30, 'username' => 'user', 'password' => 'secret', 'client' => null, 'tls' => null, 'url' => env('EMAIL_TRANSPORT_DEFAULT_URL', null), ], 'gmail'=> [ 'host' => 'ssl://smtp.gmail.com', 'port' => 465, 'username' => ' [e-mail] ', //your gmail address 'password' => 'abcd123', //your gmail password 'className' => 'Smtp', 'log' => true, 'context' => [ 'ssl' => [ 'verify_peer' => false, 'verify_peer_name' => false, 'allow_self_signed' => true ] ] ], ], 3.
