Recommended way of translating authentication errors in symfony2

问题

I need to display, for example, the "Bad credentials" message in another language. So far I found that it is thrown as an exception in
\vendor\symfony\src\Symfony\Component\Security\Core\Authentication\Provider\UserAuthenticationProvider.php
authenticate function as
throw new BadCredentialsException('Bad credentials', 0, $notFound);

I am wondering what would be the recommended way for showing this message in another language. Just changing the string in this place seems non-optimal... Also there are other messages that might probably be shown during authentication.

I am using the JMSSecurityExtraBundle and FOSUserBundle and I guess there could be some built in functionality to handle this...?

回答1:

1. Override login template: copy FOSUserBundle/Resources/views/Security/login.html.twig to app/Resources/views/Security/login.html.twig (see doc, video)

2. Add trans filter to error variable in login.html.twig (see doc):

   {{ error|trans }}

3. In your translate file src/YourBundlePath/Resources/translations/messages.{locale}.yml add:

   Bad credentials: Your error text
