Question

我有一个简单的测试应用程序，我决定如何通过WL.Client.connect()处理服务器连接。

在应用程序启动期间，不会发生身份验证过程。只需使用initOptions.js（connectOnStartup:false）进行标准初始化，然后使用wlCommonInit()调用我已将调用放入服务器（WL.Client.connect()）并使用正确的成功/失败处理程序。

当我使用移动浏览器模拟器测试应用程序时（例如：Android环境），我从浏览器控制台获得了以下堆栈跟踪：

WL.Client.init() passed! wlgap.android.js:1538

结果是wlClientInit被调用3次，直到对/apps/services/api/UnisTestAdapters/android/init的调用从服务器获得响应。

同时，对WL.Client.connect()的调用因Cannot invoke WL.Client.connect while it is already executing而失败两次。然后在从/ init调用获得响应后，我也得到wlclient connect success。

鉴于这种情况，我有一些问题：

/ init是否呼叫WL.Client.connect()无效呼叫？服务器调用是否在响应中携带相同的信息？换句话说，/ init调用是否充当WL.Client.connect（），确保所有需要connect（）调用的功能同样可用？
我是否通过调用wlClientInit（）的“重试机制”来保证，直到/ init调用终止，允许成功调用WL.Client.connect()？有没有办法阻止WL.Client.connect（）调用在成功之前失败两次？
正如我在控制台中看到的那样，您是否可以确认是否设置了默认心跳以防止会话超时？什么是默认心跳间隔？

@Daniel Gonzales：这里是wlCommonInit()代码及相关处理程序：

function wlCommonInit(){
    // Common initialization code goes here
    busyind = new WL.BusyIndicator("content");
    $('#SubscribeButton').bind('click', subscribeButtonClicked);
    $('#UnsubscribeButton').bind('click', unsubscribeButtonClicked);    

    WL.Client.connect({ onSuccess: connected, 
                onFailure: notconnected,
                timeout: 1000
    });

    WL.Logger.debug("inside wlCommonInit");
}

function connected(response){
    alert("connected");
}

function notconnected(response){
    alert("not connected");
}

请参阅这两个问题（以及他们的答案），以获得可能有用的一些解释。

至于Heartbeat，是的，它默认启用并且有a default of 20 minutes。
