How can I delete a cookie from a plugin?

Question

I am able to set a plain old cookie like this:

$cookie = new HttpCookie('myCookie', 'myValue');

I am trying to delete it like this:

$cookie = new HttpCookie('myCookie', '');
craft()->request->getCookies()->add($cookie->name, $cookie);

When I make a call to check the cookie, I get this returned:

{"name":"myCookie","value":"","domain":"","expire":0,"path":"\/","secure":false,"httpOnly":true}

I can see that the value is getting cleared, but is there any way to just totally wipe out the cooke?

Answer 1

Try deleteCookie() in HttpRequestService?

Answer 2

I wasn't able to find an answer for removing a cookie in Craft 3 so after plenty of time of trying to figuring it out, this is my conclusion.

First of all, I am setting the cookie using the following method.

$cookie = new Cookie(['name' => 'cookieName']);
$cookie->value = $data['accessToken'];
$cookie->expire = $data['expires'];
Craft::$app->getResponse()->getCookies()->add($cookie);

I kept running into a problem with the Cookies being set are read-only so in order to remove the cookie need to use response to change and remove cookies.

Craft::$app->response->cookies->remove('cookieName');
