Cakephp 3 error trying to send email with gmail - php

Question

I'm trying to send a verification email using Gmail but i get this error:
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)
I have followed the Configuring Transports guide.
Email::configTransport('gmail', [
'host' => 'ssl://smtp.gmail.com',
//'host' => 'smtp.gmail.com',
'port' => 465,
'username' => 'user#gmail.com',
'password' => 'password',
'className' => 'Smtp',
'log'=>true,
//'tls' => true
]);
$correo = new Email();
$correo
->transport('gmail')
->template('registro_exito')
->emailFormat('html')
->to('email#gmail.com')
->from('another_email#gmail.com')
->viewVars([
'nombre_sitio_secundario'=>$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:

Worth to mention that openssl es enabled on php and also i have enabled the "access for less secure apps" on Gmail configs.
Thanks for helping!.

Answer 1

Ok i found the "error". Actually the code fine, the issue is with OpenSSL in php 5.6 that verifies every encrypted connection by default BUT my local Lampp doesn't count with a ssl certificate and that couses the error.
The solution is to avoid the verification, so the configTransport code would be like this:
Email::configTransport('gmail', [
'host' => 'ssl://smtp.gmail.com',
'port' => 465,
'username' => 'user#gmail.com',
'password' => 'password',
'className' => 'Smtp',
'log' => true,
'context' => [
'ssl' => [
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
]
]
]);
I took as reference a PHPMailer answer but it was a little challenging knowing how to apply it to Cakephp3.
Hope this information is going to be helpful for somebody 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' => 'abc#gmail.com', //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. Now open your Controller file and add this code
use Cake\Mailer\Email;
use Cake\Network\Exception\SocketException;
4. Write this code on function of your controller which is in used
$msg="Your Password is generate";
$email = new Email('default');
$email
->transport('gmail')
->from(['abcx.com' => 'abcx.com'])
->to($to)
->subject($subject)
->emailFormat('html')
->viewVars(array('msg' => $msg))
->send($msg);
now you can send email from your controller by using this code
5. if this error generate(SMTP server did not accept the password.) then do this process
