Symfony 5.3 Mailer setup env vars not reading correctly-CodePudding

In a Symfony 5.3 project I am using the Mailer (..\Symfony\Component\Mailer\MailerInterface) to send mails. For devolopment I required "symfony/google-mailer" with composer and set it up in .env.local. Say username is "[email protected]" and password is "0000".

In .env.local I specified

MAILER_USER='[email protected]'
MAILER_PASSWORD='0000'

MAILER_DSN=gmail://MAILER_USER:MAILER_PASSWORD@default

which results in error

Failed to authenticate on SMTP server with username "MAILER_USER" using the following authenticators: "LOGIN", "PLAIN", "XOAUTH2". Authenticator "LOGIN" returned "Symfony\Component\Mailer\Exception\TransportException: Expected response code "235" but got code "535", with message "535-5.7.8 Username and Password not accepted.

As stated in the docs I changed the one special character in user name ("@") to it's URL-encoded form like

MAILER_USER='[email protected]'

which then results in the error

Email "[email protected]" does not comply with addr-spec of RFC 2822.

(Obviously the URL-encoding didn't work like expected (because it wasn't reversed?)) I tried to load the env vars in paramaters in services.yaml and use the parameters instead - but that lead to the first error too.

If I write the auth infos into the MAILER_DSN env var directly it just works fine without problems, like

MAILER_DSN=gmail://[email protected]:0000@default

So this seems to be a syntax problem which I can't figure out from the docs. Any hints?

CodePudding user response：

.env :

MAILER_DSN=smtp://username:[email protected]

You have to enable access to applications in google parameters (security).

CodePudding user response：

You should remove the single quotes and you need to wrap the env variables used in other env variables with ${} sic

[email protected]
MAILER_PASSWORD=0000

MAILER_DSN=gmail://${MAILER_USER}:${MAILER_PASSWORD}@default

Result:

$_SERVER['MAILER_DSN'] = "gmail://[email protected]:0000@default"
