socket.io和Java-连接失败

Question

I cannot connect to my node.js server from java using socket.io-java-client from gottox . I followed the build recommendation for socket.io v. 1.0.6 from beenjaminn here .

Here is my connect command:

socket.connect("http://192.168.1.7:8000/", this);

Here is the resulting error:

an Error occured
io.socket.SocketIOException: Error while handshaking

From javascript using the socket.io npm module I can connect fine.

var socket = io("http://" + location.host + "/player", {reconnection: false});

Note that the javascript client first requests an html page from 192.168.1.7:8000 which downloads the js above which then makes the websocket connection in the line above.

What is wrong with my java client connection?

Answer 1

I found this alternate implementation for the java client from nkzawa. It worked right out of the box.
