带有标题集的流明/laravel中的CORS问题

Question

我正在开发一个新的 lumen 项目，我正在尝试通过一个 Angular 项目与它进行交流。 我添加了一个中间件，以使用中间件为本地请求添加以下标头：

$response->header('Access-Control-Allow-Origin', '*')
    ->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS')
    ->header('Access-Control-Allow-Headers', 'X-Requested-With, Content-Type, X-Token-Auth, Authorization');

但我仍然对 CORS 有疑问。

localhost/:1 Access to XMLHttpRequest at 'http://localhost:8080/auth/sign-in' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

Request URL: http://localhost:8080/auth/sign-in
Request Method: OPTIONS
Status Code: 405 Method Not Allowed
Remote Address: [::1]:8080
Referrer Policy: strict-origin-when-cross-origin

我使用 php 内置服务器运行该项目，以前从未遇到过这样的问题。 我检查了中间件是否执行，这里没有问题，所以我没有任何想法。我在寻求帮助时发现的只是添加标头或服务器配置，所以没有帮助。

这就是我的中间件的外观和工作正常：

public function handle($request, Closure $next)
{
    $headers = [
        'Access-Control-Allow-Origin'       => '*',
        'Access-Control-Allow-Methods'      => 'HEAD, GET, POST, PUT, PATCH, DELETE, OPTIONS',
        'Access-Control-Allow-Credentials'  => 'true',
        'Access-Control-Max-Age'            => '86400',
        'Access-Control-Allow-Headers'      => 'Origin, Content-Type, X-Auth-Token,  Accept, Authorization, X-Requested-With'
    ];

    if ($request->isMethod('OPTIONS')){
        return response()->json(['method' => 'OPTIONS'], 200, $headers);
    }

    $response = $next($request);
    foreach($headers as $key => $value) {
        $response->header($key, $value);
    }

    return $response;
}

试一试，也许会有帮助。

附：请务必将请求发送到正确的 url。
