Allowed origins

[ShulV]

Didn't work for me without additional permission.
I launched the front using "Live Server" in VS Code on 5500 port.
I had to add the line .setAllowedOrigins("http://127.0.0.1:5500/") to make it work.

@Override
	public void registerStompEndpoints(StompEndpointRegistry registry) {
		registry.addEndpoint("/gs-guide-websocket")
				.setAllowedOrigins("http://127.0.0.1:5500/");//I added it
	}

.setAllowedOrigins("*")

Hi @wangzzleo and @pksilen from #82. Thanks for the issue.

I just ran through the guide and it works as is for me without needing the .setAllowedOrigins() code.

How are you launching the application? Are you using your IDE? When I tested it successfully I executed the ./gradlew bootRun command from the complete directory.

@robertmcnees, hi!

I just ran into that issue myself. There is no problem with the project itself. In the guide on the site clearly stated that you should visit localhost:8080 to interact with the app, but if you access it through 127.0.0.1:8080 ui renders just fine as well. But when you try to connect to the websocket, connection fails due to CORS policy.

You have to access the site through localhost as specified in the guide or add allowed origin. It might not be a bug, but I think it needs to be mentioned somewhere, because there is no messages in spring's logs (at least in default log configuration) and it's quite tricky to understand whats the problem.
