用于Security :: cipher（）的CakePHP空键

Question

我正在使用CakePHP 2.2.3版。我想以像 -

这样的数组格式获取我的cookie

Array
(
    [0] => Array
        (
            [username] => test1
        )

    [1] => Array
        (
            [username] => test2
        )

    [2] => Array
        (
            [username] => test3
        )

)

下面的代码我收到错误消息。请检查我的代码。

public function broadcast($username=null) { //test1 or test2 or test3
        $this->layout = '';
        $recent = $this->Cookie->read('recentUser');
        $amount = count($recent);
        $cookieVal = array('username'=>$username);
        $this->Cookie->write('recentUser.' . $amount, $cookieVal);
        $test = $this->Cookie->read('recentUser'); 
        pr($test);
        exit;
    }

输出：

Warning (512): You cannot use an empty key for Security::cipher() [CORE\Cake\Utility\Security.php, line 186]

Array
(
    [0] => Array
        (
            [username] => test3
        )

)

总是我收到上次访问的最后一个cookie时出现Secrity::chiper()错误。请问如何以上述格式显示多个cookie？

你能试一试，看看这是否能解决你的问题

public function broadcast($username=null) { //test1 or test2 or test3
    $this->layout = '';
    $recent = $this->Cookie->read('recentUser');
    $amount = count($recent);
    $amount++; //Custom
    $cookieVal = array('username'=>$username);
    $this->Cookie->write('recentUser.' . $amount, $cookieVal);
    $test = $this->Cookie->read('recentUser'); 
    pr($test);
    exit;
}
