WebSocket握手-意外的响应代码200-AngularJs和Spring Boot [英] WebSocket Handshake - Unexpected response code 200 - AngularJs and Spring Boot

问题描述

当我尝试在AngularJS应用和Spring Boot之间建立Websocket通信时，出现错误: websocket握手期间出错-意外的响应代码:200 .

When I tried to establish websocket communication between AngularJS app and Spring Boot I'm getting the error: Error during websocket handshake - Unexpected response code: 200.

这是我的JS代码:

function run(stateHandler, translationHandler, $websocket) {
    stateHandler.initialize();
    translationHandler.initialize();

    var ws = $websocket.$new('ws://localhost:8080/socket'); // instance of ngWebsocket, handled by $websocket service

    ws.$on('$open', function () {
        console.log('Oh my gosh, websocket is really open! Fukken awesome!');  
    });

    ws.$on('/topic/notification', function (data) {
        console.log('The websocket server has sent the following data:');
        console.log(data);

        ws.$close();
    });

    ws.$on('$close', function () {
        console.log('Noooooooooou, I want to have more fun with ngWebsocket, damn it!');
    });
}

这是我的Java代码:

And here is my Java code:

WebsocketConfiguration.java

WebsocketConfiguration.java

@Override
public void registerStompEndpoints(StompEndpointRegistry stompEndpointRegistry)
{
    stompEndpointRegistry.addEndpoint("/socket")
        .setAllowedOrigins("*")
        .withSockJS();
}

@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
    registry.enableSimpleBroker("/topic");
}

WebsocketSecurityConfiguration.java

WebsocketSecurityConfiguration.java

@Override
protected void configureInbound(MessageSecurityMetadataSourceRegistry messages) {
    messages
        // message types other than MESSAGE and SUBSCRIBE
        .nullDestMatcher().authenticated()
        // matches any destination that starts with /rooms/
        .simpDestMatchers("/topic/tracker").hasAuthority(AuthoritiesConstants.ADMIN)
        .simpDestMatchers("/topic/**").permitAll()
        // (i.e. cannot send messages directly to /topic/, /queue/)
        // (i.e. cannot subscribe to /topic/messages/* to get messages sent to
        // /topic/messages-user<id>)
        .simpTypeMatchers(SimpMessageType.MESSAGE, SimpMessageType.SUBSCRIBE).denyAll()
        // catch all
        .anyMessage().denyAll();
}

有人知道如何解决此问题吗?
预先谢谢你！

Does anyone have an idea how to fix this problem?
Thank you in advance!

推荐答案

我遇到了类似的问题，我正在使用chrome插件(简单的WebSocket客户端)测试我的websocket连接，并尝试连接到ws://localhost: 8080/handler/，在我的代码中定义为registry.addEndpoint("/handler").setAllowedOrigins("*").withSockJS();，但发生意外错误200.我已通过将/websocket附加到chrome扩展程序上的客户请求字符串中来解决此问题，因此您可以尝试在JS文件中更改以下行:

I had a similiar problem, I was testing my websocket connection using an chrome plugin (Simple WebSocket Client) and was trying to connect to ws://localhost:8080/handler/ which is defined in my code as registry.addEndpoint("/handler").setAllowedOrigins("*").withSockJS(); but unexpected error 200 was occuring. I've fixed this by appending /websocket to my client request string on the chrome extension, so what you could try is to change in your JS file the following line:

var ws = $websocket.$new('ws://localhost:8080/socket');

到

 var ws = $websocket.$new('ws://localhost:8080/socket/websocket');

我不知道为什么要固定它的原因，我只是偶然发现了它，如果some1可以进一步阐明它，那将是非常好的:)

I dont know the reason why this fixed it in my case i just randomly stumbled upon it, if some1 could clarify it more it would be really nice :)
