我试图在两个 docker 容器之间建立连接。一个是 nginx 服务器 + Symfony 应用程序,第二个是 Mercure。
我的应用程序运行良好,docker-compose build 也可以正常运行。问题是当我尝试测试它并尝试从 Symfony 应用程序向 Mercure 发布内容时,我收到 500 内部服务器错误,并显示“无法发送更新”。信息。
在堆栈跟踪中,我可以看到我得到了 TransportException 错误,其 env 变量与我在.env文件中的不同。应用程序正在尝试使用 HTTPS 而不是 .env 文件中定义的 HTTP。
Symfony\Component\HttpClient\Exception\TransportException:“https://mercure/.well-known/mercure”的 SSL 连接错误。在供应商/symfony/http-client/Chunk/ErrorChunk.php:65

在美居容器中,我得到:
mercure_1 | {"level":"debug","ts":1619097073.714639,"logger":"http.stdlib","msg":"http: TLS handshake error from 172.21.0.5:57420: no certificate available for 'mercure'"}

这是我的控制器,当我发布到美居主题时:
class ChatController extends AbstractController
{
/**
* @Route("/push", name="push")
* @param Request $request
* @param HubInterface $publisher
* @return Response
*/
public function push(Request $request, HubInterface $publisher): Response
{
$publisher->publish(new Update(
'/chat',
json_encode(['message' => 'hello!'])
));
return $this->json('Done');
}
}
