本地调试websocket 调用没有反应？ - WXOPEN Club

//开启websocket

openSocket:function(){

//申请

wx.connectSocket({

url: ‘http://localhost:8080/chanxiu\_v04/chat’,

data:‘need help’,

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);

}

});

//成功连接

wx.onSocketOpen(function(res){

console.log(“调用wx.onSocketOpen成功”);

});

//链接失败

wx.onSocketError(function (res) {

console.log(‘WebSocket连接打开失败，请检查！’)

})

//发送消息

sendMessage:function(){

wx.sendSocketMessage({

data: ‘i need money,can you give me some?’

})

//关闭连接

closeSocket:function(){

wx.closeSocket({

code: 0,

reason: ‘thanks’,

success: function (res) { },

fail: function (res) { },

complete: function (res) { },

});

//监听是否关闭

wx.onSocketClose(function (res) {

console.log(‘WebSocket 已关闭！’)

})

}

})

点击哪一个function，都不报任何 log 信息和其他信息？请教大神

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("/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
