InvalidConfigurationException：必须配置路径“ security.firewalls.main.remember_me”处的子节点“ key”

Question

I tried to update my vendor bundles in symfony2 using php composer.phar update, but when I did so I received an error after this line:

Updating the "app/config/parameters.yml" file

The error I get is:

[Symfony\Component\Config\Definition\Exception\InvalidConfigurationException]           
The child node "key" at path "security.firewalls.main.remember_me" must be configured. 

Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-update-cmd event terminated with an exception

[RuntimeException]                                                         
An error occurred when executing the "'cache:clear --no-warmup'" command. 

My security.yml file has the following in its firewall section:

firewalls:
    main:
        pattern: ^/
        provider: fos_userbundle
        form_login:
            csrf_provider: form.csrf_provider
            always_use_default_target_path: false
            default_target_path: webplio_site_dashboard_index
            #success_handler: webplio_site.login_success_handler
            check_path: /login_check
            login_path: /login
        logout: true
        remember_me: true
        anonymous: true
        remember_me:
            key: "%secret%"
            lifetime: 31536000 # 365 days in seconds
            path: /
            domain: ~ # Defaults to the current domain from $_SERVER

where secret is defined in my parameters.yml file

My question then is what else do I need to do in order to configure the child node "key" at path "security.firewalls.main.remember_me"?

Answer 1

You need to change from

remember_me:
    key: "%secret%"

to

remember_me:
    secret: "%secret%"

Answer 2

Move your remember_me: true to

form_login:
    ...
    remember_me: true

Check the security-reference as to see why.

Answer 3

将密钥更改为秘密即可使用
