Laravel Auth自定义接口API用户认证 基于Laravel Auth自定义接口API用户认证的实现方法（laravel和thinkphp的区别）

// 通过唯一标示符获取认证模型
public function retrieveById($identifier);
// 通过唯一标示符和 remember token 获取模型
public function retrieveByToken($identifier, $token);
// 通过给定的认证模型更新 remember token
public function updateRememberToken(Authenticatable $user, $token);
// 通过给定的凭证获取用户，比如 email 或用户名等等
public function retrieveByCredentials(array $credentials);
// 认证给定的用户和给定的凭证是否符合
public function validateCredentials(Authenticatable $user, array $credentials);
