通过okhttp3的包调用websocket，收不到服务端发出来的消息，用js的客户端代码能收到，如何解决，代码如下
importPackage(Packages["okhttp3"]); //导入包
var deviceId = device.getAndroidId();

var client = new OkHttpClient.Builder().retryOnConnectionFailure(true).build();

var request = new Request.Builder().url(baseWebSocketUrl + "?deviceId=" + deviceId + "&deviceName=" + device.product).build(); //vscode 插件的ip地址，
client.dispatcher().cancelAll();//清理一次
myListener = {
onOpen: function (webSocket, response) {
print("onOpen");
//打开链接后，想服务器端发送一条消息
// var json = {};
// json.type="hello";
// json.data= {device_name:"模拟设备",client_version:123,app_version:123,app_version_code:"233"};
// var hello=JSON.stringify(json);
// webSocket.send(hello);
},
onMessage: function (webSocket, msg) { //msg可能是字符串，也可能是byte数组，取决于服务器送的内容
print("msg");
print(msg);
},
onClosing: function (webSocket, code, response) {
print("正在关闭");
},
onClosed: function (webSocket, code, response) {
print("已关闭");
},
onFailure: function (webSocket, t, response) {
print("错误");
print(t);
}
}

var webSocket = client.newWebSocket(request, new WebSocketListener(myListener)); //创建链接

setInterval(() => { // 防止主线程退出

}, 1000);
