问在接口上访问属性

EN

Accessing id on the interface Illuminate\Contracts\Auth\Authenticatable suggest that you code against a concrete implementation. How about adding an instanceof check?

$this->tracert->log(
            'users',
            $this->auth->user()->id,
            $this->auth->user()->id,
            'Login'
        );

 /**
 * @param \Illuminate\Contracts\Auth\Guard $auth
 * @param \jorenvanhocht\Tracert\Tracert $tracert
 */
public function __construct(Guard $auth, Tracert $tracert)
{
    parent::__construct($auth);
    $this->tracert = $tracert;
}

public function __construct(Guard $auth)
{
    $this->auth = $auth;
    $this->config = objectify(config('blogify'));
    $this->auth_user = $this->auth->check() ? $this->auth->user() : false;
}
