点击哪一个function，都不报任何 log 信息和其他信息？请教大神
大神们啊，
你们看这个网上的分享代码：我的实现和他一样的呀

可是我的就是 404 异常，求解！

本地机子测试代码如下：
wx.connectSocket({
url: 'ws://localhost:8080/chanxiu_v04/WebSocket',
data:{},
header: {
'content-type': 'application/json'
},
success:function(res){
console.log("调用wx.connectSocket成功");
},
fail:function(res){
console.log("调用wx.connectSocket失败:\n"+res.data);
}
})
tomcat 正常运行的Java 后端项目chanxiu_v04如下：
import java.io.IOException;
import java.util.concurrent.CopyOnWriteArraySet;
import javax.websocket.OnClose;
import javax.websocket.OnError;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;
[@ServerEndpoint](/user/ServerEndpoint)("/WebSocket")
public class MyWebSocket {...........}
一直报以下错误：
asdebug.js:1 WebSocket connection to 'ws://localhost:8080/chanxiu_v04/WebSocket' failed: Error during WebSocket handshake: Unexpected response code: 404
