Symfony2 : Read Cookie
提问by Matt
I've set a few cookies in a Controller action and then in another action I want to read the cookie set and do something with the value. However, when trying to read the cookies, all i see is an empty array, my code is as follows:
我在 Controller 操作中设置了一些 cookie，然后在另一个操作中我想读取 cookie 集并使用该值执行某些操作。但是，在尝试读取 cookie 时，我看到的只是一个空数组，我的代码如下：
public function testSetCookieAction()
{
$value = 'ABCDEFGHI'
$cookie = new Cookie('SYMFONY2_TEST', $value, (time() + 3600 * 24 * 7), '/');
$response = new Response();
$response->headers->setCookie($cookie);
$response->send();
.
.
.
}
public function testReadCookieAction()
{
$response = new Response();
$cookies = $response->headers->getCookies();
// $cookies = array(0) { }
}
When i var_dump($_COOKIE);, I see array(1) { ["SYMFONY2_TEST"]=> string(9) "ABCDEFGHI" }Does anybody know what I am doing wrong?
当我var_dump($_COOKIE);，我看到array(1) { ["SYMFONY2_TEST"]=> string(9) "ABCDEFGHI" }有人知道我做错了什么吗？
Thanks in advance
提前致谢

You must read cookies on the Request object, not on the void Response object you just created ;)
您必须在 Request 对象上读取 cookie，而不是在您刚刚创建的 void Response 对象上读取 ;)
public function testReadCookieAction(Request $request)
{
$cookies = $request->cookies;
if ($cookies->has('SYMFONY2_TEST'))
{
var_dump($cookies->get('SYMFONY2_TEST'));
}
}
