在my laravel应用程序中，请求头值返回本地主机上的预期值.但当我把项目上传到服务器上时，它会返回空值.我创建了一个中间件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);
}
将请求中的API_ACCESS_KEY替换为Api-Access-Key，并在中间件上进行更新，
由于下划线对于标题名是无效字符，
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.
