How to pass json encode into cookie in PHP-CodePudding

When im check JSON encode with print_r it look fine => {"expiry":1636191448,"auth":true}

Then im try to store it inside cookie, but it turn into like this when i see it in browser cookies value => {"expiry":1636191866,"auth":true} enter image description here

Can anyone tell me how to fix it. Im not use this for permission system, but for other thing like read it in javascript but i got error when try to parse it

Uncaught SyntaxError: Unexpected token % in JSON at position 0 at JSON.parse ()

This are the line of code in my php file

if (Cookie::exists(Config::get('client/cookie_name'))) {
    $client = json_decode(Cookie::get(Config::get('client/cookie_name')), true);
    $expiry = $client['expiry'];
} else {
    $client = array (
        'expiry' => time()   Config::get('client/cookie_expiry')
    );
}

$client['auth'] = true;

$client = json_encode($client);
Cookie::update(Config::get('client/cookie_name'), $client, $expiry);

CodePudding user response：

Cookies are often URL-encoded (but sometimes different encodings are used). Since this isn't really standardized and by spec there is only a handful of characters that must be encoded somehow (not specified how), different systems may take different routes in handling cookie encoding, and therefore reading cookies set by one system using another system can cause issues like these.

In your case, you can call decodeURIComponent on the value first:

const json = decodeURIComponent(encodedCookieValue)
const data = JSON.parse(json)
