Symfony2: setting a cookie
提问by Nadjib Mami
I'm trying to set a cookie within a login controller to achieve "remember me" system. Even though I've used the exact code I found on the web, things for me are going wrong. I hope you can help me figure out what I'm missing.
我正在尝试在登录控制器中设置 cookie 以实现“记住我”系统。尽管我使用了我在网上找到的确切代码，但对我来说还是出错了。我希望你能帮我弄清楚我错过了什么。
Let's go through the code:
让我们来看看代码：
public function loginAction(Request $request) {
// Receiving the login form
// Get Doctrine, Get EntityManager, Get Repository
if(/* form information matche database information */) {
// Creating a session => it's OK
// Creating the cookie
$response = new Response();
$response->headers->setCookie(new Cookie("user", $user));
$response->send();
$url = $this->generateUrl('home');
return $this->redirect($url);
} else
return $this->render('***Bundle:Default:Login.html.php');
}
I included these:
我包括了这些：
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Cookie;
Note that logging-in works fine, the session has been created, but the cookie hasn't.
请注意，登录工作正常，会话已创建，但 cookie 尚未创建。

Instead of:
代替：
$response->send();
try to use:
尝试使用：
$response->sendHeaders();
After this you should be able to redirect.
在此之后，您应该能够重定向。

By default Symfony\Component\HttpFoundation\Cookieis created as HttpOnly, which triggers security measures in supporting browsers; this helps mitigate certain XSS attacks possible in javascript.
默认情况下，Symfony\Component\HttpFoundation\Cookie被创建为HttpOnly，这会触发支持浏览器的安全措施；这有助于缓解 JavaScript 中可能存在的某些 XSS 攻击。
To expose the cookie in such a browser set $httpOnlyargument to false:
要在这样的浏览器中公开 cookie，请将$httpOnly参数设置为false：
new Cookie('user', $user, 0, '/', null, false, false); //last argument
It's worth noting that at the time of this edit the framework is configured to notuse HttpOnly cookies by default: see the cookbook (cookie_httponly).
值得注意的是，在进行此编辑时，框架被配置为默认不使用 HttpOnly cookie：请参阅说明书 (cookie_httponly)。
