来自服务器 [200] 的 HTTP 响应不允许 HTTP 升级到 WebSocket [英] The HTTP response from the server [200] did not permit the HTTP upgrade to WebSocket
问题描述
我的 websocket 客户端在 STOMP Java 客户端(Spring 项目)中开发，服务器在 Spring 启动中实现.
当客户端/服务器握手发生时，我遇到了连接升级问题.
Java 客户端代码
List运输 = 新的 ArrayList<>(1);transports.add(new WebSocketTransport(new StandardWebSocketClient()));SockJsClient sockjsClient = new SockJsClient(transsports);WebSocketStompClient stompClient = new WebSocketStompClient(sockjsClient);stompClient.setMessageConverter(new MappingJackson2MessageConverter());stompClient.setTaskScheduler(new ConcurrentTaskScheduler());StompSessionHandler sessionHandler = new SessionHandler();stompClient.connect("ws://localhost:9090/health", sessionHandler); 服务器端
@Override公共无效 registerStompEndpoints(StompEndpointRegistry stompEndpointRegistry) {stompEndpointRegistry.addEndpoint("/health").setAllowedOrigins("*").withSockJS();}@覆盖public void configureMessageBroker(MessageBrokerRegistry 注册表){registry.enableSimpleBroker("/topic");registry.setApplicationDestinationPrefixes("/app");}连接到服务器时客户端产生的异常

请帮我解决这个问题.
为您的问题提供有用的解决方案为时已晚.今天我面临着你已经经历过的同样问题.不幸的是，Spring Framework 示例和官方资源并未完全引用.因此，我想写下我是如何创建和运行它的.首先，原始答案不属于我.我在

I have my websocket client developed in STOMP Java client (Spring project) and server implemented in Spring boot.
When the client/server handshake happens, I am getting a connection upgrade issue.
Java Client Code
List<Transport> transports = new ArrayList<>(1);
transports.add(new WebSocketTransport(new StandardWebSocketClient()));
SockJsClient sockjsClient = new SockJsClient(transports);
WebSocketStompClient stompClient = new WebSocketStompClient(sockjsClient);
stompClient.setMessageConverter(new MappingJackson2MessageConverter());
stompClient.setTaskScheduler(new ConcurrentTaskScheduler());
StompSessionHandler sessionHandler = new SessionHandler();
stompClient.connect("ws://localhost:9090/health", sessionHandler);
Server side
@Override
public void registerStompEndpoints(StompEndpointRegistry stompEndpointRegistry) {
stompEndpointRegistry.addEndpoint("/health")
.setAllowedOrigins("*")
.withSockJS();
}
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/topic");
registry.setApplicationDestinationPrefixes("/app");
}
Exception generated at client side while connection to server
16:18:50.955/3771 [SimpleAsyncTaskExecutor-1] ERROR o.s.w.s.s.c.DefaultTransportRequest - No more fallback transports after TransportRequest[url=ws://localhost:9090/health/29/344d627baac949f5bab5506f05f1a7eb/websocket]

In the tomcat localhost_access_log I see the below request info

I didn't find any info on how to fix this issue and what is causing it.
Please help me resolve this issue.
Too late to be able to present a helpful resolution for your problem. Today I'm facing the same issue that you have already experienced. Unfortunately, Spring Framework samples and official resources are not referencing entirely. Therefore, I would like to write about how I made it up and running. Firstly, the original answer doesn't belong to me. I found it at https://code5.cn/so/java/783097.
As far as I can understand, to be able to upgrade the WebSocket protocol from HTTP, we should extend the "WebSocketConfiguration" part a little bit with desired capabilities.
RequestUpgradeStrategy upgradeStrategy = new TomcatRequestUpgradeStrategy();
registry.addEndpoint("/hello")
.withSockJS();
registry.addEndpoint("/hello")
.setHandshakeHandler(new DefaultHandshakeHandler(upgradeStrategy))
.setAllowedOrigins("*");
After making the above adjustments, you could comprehend regarding switching between protocols through sniffing WireShark.
I hope it would be helpful for someone who is looking for a way to get rid of errors.
