Question

如果我尝试这是带有静态方法的类：

public static function chkLog($role)
{
    $userrole = $this->getRequest()->getSession()->read('userrole');
   return $userrole;
   /// more code

甚至尝试过：

    public static function chkLog($role)
{
    $userrole = Session::read('userrole');
   return $userrole;
   /// more code

在laravel中，我可以：

public static function userRole($role = null)
{
    $userrole = Auth::user()->role;
    $checkrole = explode(',', $userrole);
    if (in_array($role, $checkrole)) {
        return $role;
    }
    return false;
}

用法

public function scopegetPets($query, $petsearch = '')
{
    $petsearch = $petsearch . "%";
    $query = Pet::where('petname', 'like', $petsearch);
    if (ChkAuth::userRole('admin') === false) {
        $userid = Auth::user()->id;
        $query->where('ownerid', '=', $userid);
    }
    $results = $query->orderBy('petname', 'asc')->paginate(5);
    return $results;
}

但是在cakephp中，我必须这样写：

    public static function __callStatic($method, $params)
{
    $instance = ChkAuth::class;
    $c = new $instance;
    return $c->$method(...array_values($params));
}

为了称呼它：

public function userRole($role = null)
{
    $userrole = $this->getRequest()->getSession()->read('userrole');
    $checkrole = explode(',', $userrole);
    if (in_array($role, $checkrole)) {
        return $role;
    }
    return false;
    // more

和用法：

   public function getPets($offset = "", $rowsperpage = "", $petsearch = "")
{
    $pagingQuery = "LIMIT {$offset}, {$rowsperpage}";
    $petsearch = $petsearch . "%";
    if (Auth::chkRole('admin') === true) {
        return DB::select("SELECT * FROM " . PREFIX . "pets " . $pagingQuery);
    }
    $authid = Auth::authId();
    return DB::select("SELECT * FROM " . PREFIX . "pets WHERE ownerid = :authid " . $pagingQuery, ["authid" => $authid]);
}

所以基本上，我试图找出如何在静态方法内的Cake php中使用会话。

请注意__callStatic的工作原理，但作为一轮工作。

CakePHP的Router类包含一个静态函数以返回请求对象。请求对象包括返回会话的功能。所以：

Router::getRequest()->session()

或者，从3.5版开始：

Router::getRequest()->getSession()

以静态方式使用会话（cakephp 4和3.6+）
