[FIXED] How to get header request value in my laravel app on production?

Issue

In my laravel app request header value returns an expected value on my localhost. but when i upload project on server its returning null value. I created a middleware Authkey.php

public function handle(Request $request, Closure $next)
{
    $token = $request->header('API_ACCESS_KEY');
    dd($token);
    if ($token !=env('API_ACCESS_KEY')) {
           return response()->json(['message' => 'Unauthorized'],401);
    } 
    return $next($request);
}

Solution

Replace the API_ACCESS_KEY in your request with Api-Access-Key , also update it at your middleware too ,

as the underscores are invalid characters for header names,

Translation of headers to environment variables is more strict than
 before to mitigate some possible cross-site-scripting attacks via header injection.
 Header names containing invalid characters (including underscores) are
 no longer converted to environment variables.
