我的應用程式正在使用 Symfony 5.4.2，并且依賴于新的 Authenticator Manager。
我最近遇到了與session_open(). 在調查時，我注意到整個 User 物體都存盤在會話檔案中（作為 PHP serialized 字串），以_sf2_attributes|.
因此，每個相關物體也都存盤在那里（每個屬性、用戶購買及其詳細資訊等），這可能非常繁重（我有超過 100 Kb 的會話檔案，這對我來說聽起來很大）。
預計會以這種方式作業嗎？
有沒有辦法防止序列化所有用戶物體屬性？
uj5u.com熱心網友回復：
您必須序列化您的用戶物體類實作\Serializable介面和定義serialize，unserialize和__sleep方法，定義哪些屬性將包含在會話中。您將__sleep授予只有特定屬性才能進入序列化程序；例如：
/**
* Usuario
*
* @ORM\Table(name="usuario", uniqueConstraints={@ORM\UniqueConstraint(name="usuario_username_uniq", columns={"username"})}, indexes={@ORM\Index(name="usuario_rol_idx", columns={"rol_id"}), @ORM\Index(name="usuario_nodo_idx", columns={"estructura_organizativa_id"}), @ORM\Index(name="usuario_id_publico_idx", columns={"id_publico"})})
* @ORM\Entity(repositoryClass="App\Repository\UsuarioRepository")
* @UniqueEntity("username", message="Ya existe un usuario con ese identificador")
*/
