我正在尝试使用 Lighthouse 验证订阅（文档）

const pusher = new Pusher('blabla', {
  cluster: 'eu',
  forceTLS: true,
  authEndpoint: 'https://app.test/graphql/subscriptions/auth',
  auth: {
    headers: {
      Authorization: `Bearer blabla`
    }
  }
})

但是当我运行订阅查询时，我得到了这个

Unable to retrieve auth string from auth endpoint.
Received status 403 from https://app.test/graphql/subscriptions/auth.
Clients must be authenticated to join private or presence channels.
See: https://pusher.com/docs/authenticating_users

所以我决定顺其自然。

这是失败的地方：

//
// Nuwave\Lighthouse\Subscriptions > class Authorizer
//

public function authorize(Request $request): bool

  $subscriber = $this->storage->subscriberByRequest(
      $request->input(),
      $request->headers->all()
  );

  //  "$subscriber" is empty here. ==> return false

  if (! $subscriber) {
      return false;
  }

  ...
}

走进$this->storage->subscriberByRequest()去，我得到

//
// Nuwave\Lighthouse\Subscriptions > class StorageManager
//

public function subscriberByRequest(array $input, array $headers): ?Subscriber
{
    $channel = Arr::get($input, 'channel_name');
    return $channel
        ? $this->subscriberByChannel($channel)
        : null;
}

public function subscriberByChannel(string $channel): ?Subscriber
{
    $key = self::SUBSCRIBER_KEY.".{$channel}";
    // At this point, "$key" equals "graphql.subscriber.private-lighthouse-blablabla"

    return $this->cache->get($key); //  This returns NULL
}

有人可以帮忙吗？

我错过了什么？

我的配置：

# composer.json
"php": "^7.4",
"laravel/framework": "^7.0",
"nuwave/lighthouse": "^4.11",
"pusher/pusher-php-server": "^4.1"

# .env
BROADCAST_DRIVER=pusher
CACHE_DRIVER=file
LIGHTHOUSE_SUBSCRIPTION_STORAGE=file
LIGHTHOUSE_BROADCASTER=pusher

# config/lighthouse.php
'subscriptions' => [
    'storage' => env('LIGHTHOUSE_SUBSCRIPTION_STORAGE', 'file'),
    'broadcaster' => env('LIGHTHOUSE_BROADCASTER', 'pusher')
],
