Symfony2：读取Cookie [英] Symfony2 : Read Cookie

问题描述

我在Controller操作中设置了几个Cookie，然后在另一个操作中，我想读取cookie集合并使用值进行操作。但是，当尝试读取cookie时，我看到的是一个空数组，我的代码如下：

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:

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) { } 
}

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？

When i var_dump($_COOKIE);, I see array(1) { ["SYMFONY2_TEST"]=> string(9) "ABCDEFGHI" } Does anybody know what I am doing wrong?

提前感谢

推荐答案

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）;

You must read cookies on the Request object, not on the void Response object you just created ;)

public function testReadCookieAction(Request $request)
{
    $cookies = $request->cookies;

    if ($cookies->has('SYMFONY2_TEST'))
    {
        var_dump($cookies->get('SYMFONY2_TEST'));
    }
}
