Ibm mobilefirst IBM Worklight 5.0.6-/init vs WL.Client.connect（）调用

我有一个简单的测试应用程序，其中我决定如何通过

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，然后调用

wlCommonInit（）

，我在其中使用正确的成功/失败处理程序调用服务器（

WL.Client.connect（）

）

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

请看这两个问题（好吧，他们的答案），以获得一些可能有用的解释

至于Heartbeat，是的，它在默认情况下是启用的，并且具有。

您的wlCommonInit上的代码是什么？Idan，我已经看到了这些帖子，但他们没有解释我为什么会出现两次错误“无法在执行时调用WL.Client.connect”，就好像我发出了几个WL.Client.connect（）调用一样。但是在wlCommonInit（）中，我只调用了一次WL.Client.connect（），所以我想知道该调用是否与/init调用冲突，可能仍然在运行中。如果是这样的话，我怎样才能避免呢？wlCommonInit（）不是应该在WL.Client.init（）初始化WL框架之后调用吗？我假设/init请求与WL.Client.init（）调用相关，不是吗？谢谢。伊丹，我也有类似的问题。调用InvokeProcedure时，我发现以下

加载资源失败：在此服务器上找不到请求的URL。

@Quake，如果使用connectOnStartup:true，则会导致额外的连接。

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");
}
