我在sfGuard使用 Symfony 应用程序获取令牌登录时遇到问题。Symfony 应用程序通过 WordPress 插件访问。WordPress 插件很简单，它iframe在 WP 控制面板中嵌入了带有令牌字符串的 a：
<iframe src="/app/index.php/api/authenticate/**token**" width="100%" height="100%">
这在实时服务器上运行良好。在挖掘了我的错误日志后，我发现了这个：
PDO Connection Error: SQLSTATE[28000] [1045] Access denied for user 'db_user'@'localhost' (using password: YES), referer: http://****/wp-admin/admin.php?page=custom-sms.php
PHP Fatal error: Call to a member function prepare() on a non-object in /var/www/vhosts/domain.com/sfapp/lib/vendor/symfony/lib/storage/sfPDOSessionStorage.class.php on line 162, referer: http://****/wp-admin/admin.php?page=custom-sms.php
奇怪的是，虽然我能够在网站前端写入/连接到数据库。什么可能导致应用程序不使用database.yml配置文件中设置的数据库用户名和密码？
app.yml文件：
all:
security:
#to auto-login to the SMS alert system from inside Wordpress admin
token: **token**
username: user@web.com
顺便说一句，我以前从未使用过 Symfony，而且我继承了这个网站，没有任何文档。
更新
database.yml文件：

第二次更新：
要添加，我手动将$env变量设置为在新服务器上prod进行测试。/web/index.php
