如何在laravel中获得cookie值

I am setting cookie in in blade file using javascript by below piece of code

function showPosition(position) {
    var lat=position.coords.latitude;
    var lng=position.coords.longitude;
    document.cookie="lat=" + lat;
    document.cookie="lng=" + lng;
    //var allcookies = document.cookie;
    //alert(allcookies);
    localStorage.setItem('latLng',latLng);
}

and in model i try to get cookie

$lat = Cookie::get('lat');
$lng = Cookie::get('lng');
dd($lat);

but it shows me null. Any help please.

Laravel stores cookies encrypted, so Cookie::get() will only retrieve cookies set by Laravel. You should use the native $_COOKIE['lat'] in PHP to retrieve cookies set for example in JavaScript.

You can find out more here:

https://laravel.com/docs/4.2/requests#cookies

Try to understand the concept first. Check this line:

localStorage.setItem('latLng',latLng);

You are using localStorage here and then:

$lat = Cookie::get('lat');

you are trying to get it with Cookie.
