The client and server couldn't connect when I use WebSocket under windows8 9200.

[王利]

client and server's codes keep same with https://github.com/astaxie/build-web-application-with-golang/blob/master/ebook/08.2.md ,I open the client with Chrome, server with CMD, and the console said:

onload 
index.html:10 WebSocket connection to 'ws://localhost:1234/' failed: Error during WebSocket handshake: Unexpected response code: 403 
index.html:12 connection closed (1006) 
index.html:19 WebSocket is already in CLOSING or CLOSED state.  

No message at server-end.

I don't know how to dea with it. It just couldn't run the same result with the github's. Thx for your help!

Change the server code to print out the error value, rather than just printing the fact there was an error. That should get you a little further.

The Origin header is not set which will probably throw a 403.

You will have to set this where ever you are serving up the html page from.
