Question

出于某种原因，我无法从其他控制器读取我的cookie。代码非常简单，不确定它有什么问题。它声称cookie是空的......

PagesController：

public $components = array('Cookie');

public function beforeFilter() {
        parent::beforeFilter();
        //cookie setings   
        $this->Cookie->name = 'cookie_test';
        $this->Cookie->time = 3600;  // or '1 hour'
        $this->Cookie->path = '/';
        $this->Cookie->domain = 'localhost';
        $this->Cookie->secure = false;
        $this->Cookie->key = '39lbkutg1i2l0kta6785d8qki5';
        $this->Cookie->httpOnly = true;

    }

$this->Cookie->write('ad_id', $ad_id, false, time()+2592000);

NamesearchController中的

：

$variable = $this->Cookie->read('ad_id');

Answer 1

您创建了一个名为cookie_test的Cookie，并添加了一个名为ad_id的密钥。如果你查看你的cookies（页面信息或Firebug），你会看到一个名为cookie_test[ad_id]的人。

Cookie组件中方法write()和read()的第一个参数是$key，而不是Cookie的名称。

所以，如果你想阅读你创建的cookie，你必须这样做：

$this->Cookie->name = 'cookie_test';
$variable = $this->Cookie->read('ad_id');

Answer 2

您应该在AppController中编写以下行，而不是PagesController。

public $components = array('Cookie');

public function beforeFilter() {
    parent::beforeFilter();
    //cookie setings   
    $this->Cookie->name = 'cookie_test';
    $this->Cookie->time = 3600;  // or '1 hour'
    $this->Cookie->path = '/';
    $this->Cookie->domain = 'localhost';
    $this->Cookie->secure = false;
    $this->Cookie->key = '39lbkutg1i2l0kta6785d8qki5';
    $this->Cookie->httpOnly = true;

}
