.net 无法解析远程名称：'；api.parse.com'；

我正在.NET通用应用程序中使用解析API。我已将解析库添加到PCL中，然后将.NET WinRT库与实际的Windows RT项目一起包含。以下是我的服务电话

public async Task<IEnumerable<BasicTask>> GetTasksAsync()
{
    ParseQuery<ParseObject> query = ParseObject.GetQuery(typeof(BasicTask).Name);
    IEnumerable<ParseObject> parseObjects = await query.FindAsync();

    // Convert the parse objects returned from the cloud into our local model representation.
    // We do this in order order to maintain support for the model across multiple cloud services
    // instead of restricting ourselves to the entire app using ParseCloud only.
    return parseObjects.Select(po => this.ConvertParseObjectToDutyTask(po));
}

我从Parse中取回所有记录（仅1个atm）

当我在Windows App Store应用程序中使用相同的方法时，我得到一个

无法解析远程名称：“api.parse.com”

异常。目前，我正在页面加载事件中调用它。事件处理程序在我的视图模型中调用一个initialize方法，该方法要求存储库执行所有任务。存储库从服务获取任务并返回它

页面

private async void pageRoot_Loaded(object sender, Windows.UI.Xaml.RoutedEventArgs e)
{
    if (!(this.DataContext is MainPageViewModel))
    {
        return;
    }
    var vm = this.DataContext as MainPageViewModel;
    await vm.Initialize();

    this.TasksList.ItemsSource = vm.Tasks;
}

查看模型

public async Task Initialize()
{
    try
    {
        IEnumerable<BasicTask> tasks = await this.repository.GetTasksAsync();
        this.tasks = new ObservableCollection<BasicTask>(tasks);
    }
    catch (Exception)
    {
        throw;
    } 
}

有人知道为什么它在单元测试中运行良好，但在应用程序中却无法访问服务吗？我使用的异步模式是否错误？我不确定这是否会影响它，因为异常发生在调用解析服务时

编辑

为了澄清，我有一个WinRT项目，它引用了一个通用PCL存储库库和一个通用PCL服务库。调用

后立即等待query.FindAsync（）它失败了。我的单元测试是一个标准的Windows单元测试项目，它引用了完全相同的两个PCL库。两者之间的唯一区别是一个是WinRT，另一个是标准的Windows单元测试。两者都使用相同的库，并且都使用async进行调用。这两个库的目标都是Windows 8、Windows Phone 8和.NET 4.5

我是否必须授予我的应用程序特殊权限才能允许在WinRT设备上进行网络访问

任何帮助都会很棒
 我终于解决了这个问题。您必须修改Package.appxmanifest文件，以告知设备应用程序需要出站internet权限。这解释了为什么单元测试有效而应用程序无效

当我在应用程序上启用internet权限时，网络呼叫成功，我从Parse返回了数据。我希望这个框架会抛出一个
InternetCapabilityNotSet
异常之类的东西。当没有设置正确的功能时，它当前正在抛出的任何内容。
您是否有可能使用代理？很明显，您的应用程序无法解析api.parse.com名称。正如@YuvalItzchakov所言，这可能是一个代理问题。您可能想使用Fiddler查看您的请求/响应。我不是通过代理。正如我提到的，单元测试通过了，但应用程序失败了。两者都在同一台机器上，采用相同的解决方案。所以我不知道为什么应用程序不能解决它。
