How to set and get Cookie in laravel
提问by S.M_Emamian
I would like to set and get value in cookie but it doesn't work:
我想在 cookie 中设置和获取值，但它不起作用：
Cookie::queue('online_payment_id', "1", 15);
$value = Cookie::get('online_payment_id');
dd($value);
dd()returns null;
dd()返回null；
I used below way but I got this message:
我使用以下方式，但我收到了这条消息：
Method cookie does not exist.
request()->cookie('online_payment_id');
$value = response()->cookie('online_payment_id', "1", 15);
dd($value);

Add at the top of the file add use Symfony\Component\HttpFoundation\Cookie;or simply use Cookie;
在文件顶部添加 adduse Symfony\Component\HttpFoundation\Cookie;或干脆use Cookie;
To Generating Cookie Instances
生成 Cookie 实例
$cookie = cookie('name', 'value', $minutes);
return response('Hello World')->cookie($cookie);
Retrieving Cookies From Requests you can use Request be sure you use Request $requestin you method.
从请求中检索 Cookie，您可以使用 Request 确保Request $request在您的方法中使用。
$value = $request->cookie('name');

Even if you carefully follow the Laravel documentation regarding how to set cookies, you may end up going crazy for hours (as I did today) because you just can't get your cookies set!
即使您仔细遵循 Laravel 文档中关于如何设置 cookie 的内容，您也可能会疯狂几个小时（就像我今天所做的那样），因为您无法设置 cookie！
I finally discovered why my cookies weren't being set... I was also using the dump()function to display data while I tested the code. The dump()function sends output to the browser, which requires headers to be sent. Cookies also have to be sent with the headers, so if you're using dump(), your cookies will never be sent!
我终于发现了为什么我的 cookie 没有被设置......我也在dump()测试代码时使用该函数来显示数据。该dump()函数将输出发送到浏览器，这需要发送标头。Cookie 也必须与标头一起发送，因此如果您使用的是dump()，您的 Cookie 将永远不会被发送！
I hope this helps others who will very likely run into this situation.
我希望这可以帮助其他很可能会遇到这种情况的人。

public function setCookie(Request $request) {
Cookie::queue('name', $request->test, 10);
return view('home');
}
Here Cookie::queue($cookie_name, $data, $life_time_of_this_cookie);
这里 Cookie::queue($cookie_name, $data, $life_time_of_this_cookie);
and simply print cookie where you want to show data.
并简单地在您想要显示数据的地方打印 cookie。
{{ Cookie::get('name') }}
