提问by shakir

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

我正在使用 javascript 通过以下代码在刀片文件中设置 cookie

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

在模型中,我尝试获取 cookie

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

but it shows me null. Any help please.

但它显示我为空。请任何帮助。

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.

Laravel 存储加密的 cookie,因此Cookie::get()只会检索 Laravel 设置的 cookie。您应该使用$_COOKIE['lat']PHP 中的本机来检索例如在 JavaScript 中设置的 cookie。

Try to understand the concept first. Check this line:

先试着理解这个概念。检查这一行:

localStorage.setItem('latLng',latLng);

You are using localStoragehere and then:

你在localStorage这里使用,然后:

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

you are trying to get it with Cookie.

你正试图用Cookie.
