Can't get onclose function!

Creator 2.x
#1

[ERROR] (C:/CocosCreator/resources/cocos2d-x/cocos/scripting/js-bindings/proj.android/…/manual/jsb_websocket.cpp, 212): Can’t get onclose function!

使用的是wss

compileSdkVersion 26
buildToolsVersion ‘26.0.2’

defaultConfig {
    minSdkVersion PROP_TARGET_SDK_VERSION
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
}

求教！

网络模块有没有勾选

原因是用的wss，paho-mqtt在安卓端没有集成证书，改了创建链接的代码
if (cc.sys.isBrowser) {
if (this.connectOptions.mqttVersion < 4) {
this.socket = new WebSocket(wsurl, [“mqttv3.1”]);
} else {
this.socket = new WebSocket(wsurl, [“mqtt”]);
}
} else {
if (cc.sys.os != cc.sys.OS_IOS) {
var pemUrl = cc.url.raw(“resources/cert/cert.pem”);
if (cc.loader.md5Pipe) {
pemUrl = cc.loader.md5Pipe.transformURL(pemUrl)
}
this.socket = new WebSocket(wsurl, null, pemUrl);
} else {
if (this.connectOptions.mqttVersion < 4) {
this.socket = new WebSocket(wsurl, [“mqttv3.1”]);
} else {
this.socket = new WebSocket(wsurl, [“mqtt”]);
}
}
}

没用wss也会报这个错，升级到最新版本ws连接就没这个问题了
