Question

我在MobileFirst Platform中有一个示例项目“调用适配器过程”。它在MFP控制台中预览时接收Feed并显示值，但在添加iPad环境并在Xcode中运行后，它不会获取任何Feed，而是在Xcode控制台中显示错误：

无法提取Feed

并在iOS模拟器中：

服务不可用

适配器代码

<procedure name="getFeedsFiltered"/>

JS代码

var busyIndicator = null;

function wlCommonInit(){
busyIndicator = new WL.BusyIndicator();
loadFeeds();
}

function loadFeeds(){
busyIndicator.show();

/*
 * The REST API works with all adapters and external resources, and is supported on the following hybrid environments: 
 * iOS, Android, Windows Phone 8, Windows 8. 
 * If your application supports other hybrid environments, see the tutorial for MobileFirst 6.3.
 */
var resourceRequest = new WLResourceRequest("/adapters/RSSReader/getFeedsFiltered", WLResourceRequest.GET);
resourceRequest.setQueryParameter("params", "['technology']");
resourceRequest.send().then(
        loadFeedsSuccess,
        loadFeedsFailure
);
}


function loadFeedsSuccess(result){
WL.Logger.debug("Feed retrieve success");
busyIndicator.hide();
if (result.responseJSON.Items.length>0) 
    displayFeeds(result.responseJSON.Items);
else 
    loadFeedsFailure();
}

function loadFeedsFailure(result){
WL.Logger.error("Feed retrieve failure");
busyIndicator.hide();
WL.SimpleDialog.show("Engadget Reader", "Service not available. Try again later.", 
        [{
            text : 'Reload',
            handler : WL.Client.reloadApp 
        },
        {
            text: 'Close',
            handler : function() {}
        }]
    );
}

function displayFeeds(items){
var ul = $('#itemsList');
for (var i = 0; i < items.length; i++) {
    var li = $('<li/>').text(items[i].title);
    var pubDate = $('<div/>', {
        'class': 'pubDate'
    }).text(items[i].pubDate);

    li.append(pubDate);

    ul.append(li);
}

我无法重现此错误确保这些是您采取的步骤：

将“调用混合应用程序中的适配器程序”sample project
右键单击适配器文件夹，然后选择运行方式＆gt;部署MobileFirst适配器
右键单击项目文件夹，然后选择新建＆gt; MobileFirst Environment ，添加iPad环境
右键单击iPad文件夹，然后选择运行方式＆gt; Xcode项目
单击“在Xcode中运行”

对我来说，通过以上步骤，我能够在iOS模拟器中成功运行示例应用程序=显示应用程序并检索提要。
