I get a status 200 when connecting to the websocket, but it is an error?

Question

My error shows up in the console of my browser:

\"WebSocket connection to \'ws://localhost:32768/DspClusterWebServices/myHandler\' failed: Unexpected response

Answer 1

Please check http://procbits.com/connecting-to-a-sockjs-server-from-native-html5-websocket!

After you append /websocket (to your URL), it will give you the error

Failed to parse Origin header value [null]

;) , which then will in turn lead you to that link.

You'll have to add .setAllowedOrigins("*") to your addHandler() method, and then it could finally work!

Answer 2

For those guys like me who use angular + springboot and got this error. please check if you have enabled the redirect or forward all non api endpoint request back to index.html. like:

@RequestMapping(value = "/**/{[path:[^\\.]*}")
    public String redirect() {
        // Forward to home page so that route is preserved.
        return "forward:/index.html";
    }

If you do, disable it and you will get 101

Answer 3

Don't know if this is too late but a solution that I stumbled upon is simply appending the string /websocket after the websocket endpoint that you declared in the spring boot server. This will help keep both the forwarding logic and connect and establish a websocket connection.

Answer 4

As my another answer:[https://stackoverflow.com/a/53272666/2930417][1]

I use springboot 2 +STOMP。

remove .withSockJS(),then everything is ok.

I don't know the reason,but works for me.

Answer 5

Have a look at the specification . The server should respond with 101 to signal protocol change from http to ws.

Answer 6

Please check that if 'ws://localhost:32768/DspClusterWebServices/myHandler' is correct.
