spring - Spring cloud gateway，socket.io 尝试连接时报错 404

Question

我正在尝试使用 Spring 云网关和 socket.io websocket。

微服务应用程序提供一个 http 服务和一个 websocket 服务（用 socket.io 实现）。

当我尝试从客户端连接到网关时，socket.io 工作，但在网关上我收到此错误：

我的网关配置如下：

@Configuration
public class GatewayConfiguration {

      @Bean
      public RouteLocator gatewayRouter(RouteLocatorBuilder builder) {
        return builder
            .route(
                p -> p.path("/server/socket.io/**").filters(f -> f.stripPrefix(2)).uri("lb:ws://server/"))
            .route(
                p -> p.path("/server/**").filters(f -> f.stripPrefix(1)).uri("lb://server/"))
            .build();
      }
}

在我的客户端，一个反应应用程序中，websocket 路径是 /server/socket.io/?username=xxxx&token=yyy

我的错误在哪里？为什么我看到很多错误？非常感谢安吉洛
