I have got a WebSocket app which is developed in Spring maven framework which works really well when it is deployed in localhost:8080/test where test is my socket endpoint. Now I deployed the app in my AWS cloud server and tried to connect to the cloud server using the same method but using a specific URL (For example, https://example.com/test) where test is the WebSocket endpoint and URL(example.com) being my link similar to localhost:8080. I have also opened the port needed for the necessary connection in the security group.
For localhost it works fine but when I try to connect it to my cloud server always the WebSocket returns with an error function of status 400. I am not certain why a status 400 is coming because according to my knowledge status 400 means that it is a bad request. What am I doing wrong guys?
I am pasting my java code below
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/topic");
config.setApplicationDestinationPrefixes("/ws/");
}
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/test").setAllowedOrigins("*"); // This will allow you to use ws://localhost:8080/test to establish websocket connection
registry.addEndpoint("/test").setAllowedOrigins("*").withSockJS(); // This will allow you to use http://localhost:8080/test to establish websocket connection
}
}
Is it any configuration that I am missing or any code snippet that I am missing?
P.S: All my testing is done mainly using POSTMAN Websocket request and YES!!! I use wss:// for example.com
My POSTMAN URL tends to be wss://example.com/test ------> Doesn't work
ws://localhost:8080/test -------> This works
