我們正在使用Live Connect SDK 5.0從我們的Windows Phone 7.5應用程序中檢索SkyDrive中的圖片。從Windows Phone 7訪問SkyDrive的問題
以下的應用程序代碼(簡體)用於工作到幾天前。現在,當我們嘗試訪問imageStream(或回調中捕獲的任何其他信息)時,我們得到一個異常(HResult = -2147024809,「價值不在預期範圍內」,但像往常一樣沒有提到違規價值)。我們檢查了我們的代碼庫,最近在產品的這個區域沒有代碼改變。
是否有任何API更改?有沒有辦法(Fiddler,但對於不是IE的應用程序)檢查網絡流量,希望從服務器傳輸更多信息?是否存在可能會受到干擾的本地值?
下面是相關代碼:
public partial class OptionsPage : PhoneApplicationPage
{
private LiveConnectClient _liveClient = null;
public OptionsPage()
{
InitializeComponent();
}
private void OnSessionChanged(Object sender, LiveConnectSessionChangedEventArgs args)
{
if (args != null && args.Session != null && args.Session.Status == LiveConnectSessionStatus.Connected)
{
this._liveClient = new LiveConnectClient(args.Session);
this.GetUserPicture();
}
}
private void GetUserPicture()
{
var memoryStream = new MemoryStream();
_liveClient.DownloadCompleted += new EventHandler<LiveOperationCompletedEventArgs>(this.GetUserPictureCallback);
_liveClient.DownloadAsync("/me/picture?return_ssl_resources=true", memoryStream, memoryStream);
}
private void GetUserPictureCallback(object sender, LiveOperationCompletedEventArgs e)
{
_liveClient.DownloadCompleted -= this.GetUserPictureCallback;
try
{
if (e.Error == null)
{
MemoryStream imageStream = e.UserState as MemoryStream;
BitmapImage b = new BitmapImage();
b.SetSource(imageStream);
}
else
{
MessageBox.Show(e.Error.Message, "Windows Live Error", MessageBoxButton.OK);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "SkyDrive Exception", MessageBoxButton.OK);
}
}
}
而且SignInButton定義如下:
<live:SignInButton Content="Button" Height="65" HorizontalAlignment="Left" Margin="110,41,0,0"
Name="signInButton1" VerticalAlignment="Top" Width="215" ClientId="[REAL_CLIENT_ID]"
Scopes="wl.offline_access wl.signin wl.basic wl.skydrive wl.skydrive_update"
RedirectUri="https://oauth.live.com/desktop"
Branding="Skydrive"
TextType="SignIn"
Background="Red"
SessionChanged="OnSessionChanged" />
您可以使用Fiddler嗅探應用程序流量。 – EricLaw 2012-01-13 22:11:58
