通过其API从Azure上传到Youtube

我正在尝试通过其API上传到youtube，当我在当地做时，它工作正常。当它在我的 Azure 应用程序上时，它如何得到 (403( 禁止

这是我的代码：

YouTubeRequestSettings settings = new YouTubeRequestSettings("XXXXX", token, userName, Password);
YouTubeRequest request = new YouTubeRequest(settings);
Video newVideo = new Video();
newVideo.Title = "Test";
newVideo.Tags.Add(new MediaCategory("Autos", YouTubeNameTable.CategorySchema));
newVideo.Keywords = "car";
newVideo.Description = "My first try";
newVideo.YouTubeEntry.Private = false;
newVideo.Tags.Add(new MediaCategory("devTag",
  YouTubeNameTable.DeveloperTagSchema));
newVideo.YouTubeEntry.MediaSource = new MediaFileSource(**SaveFileToLocal**(fileUpload), fileUpload.ContentType);
Video createdVideo = request.Upload(newVideo);
private string **SaveFileToLocal**(HttpPostedFileBase fileUpload)
{
    string uploadedFilePath;
    if (Local)
    {
        var uploadPath = Server.MapPath("~/AlbumsUploads//" + "RD");
        uploadedFilePath = Path.Combine(uploadPath, fileUpload.FileName);
    }
    else
    {
        LocalResource localResource = RoleEnvironment.GetLocalResource("LocalWebRoleStorage");
        string[] paths = { localResource.RootPath, DateTime.Now.Ticks.ToString() + "_temp" + fileUpload.FileName.Substring(fileUpload.FileName.LastIndexOf('.')) };
        uploadedFilePath = Path.Combine(paths);
    }
    using (var fs = new FileStream(uploadedFilePath, FileMode.Create))
    {
        var buffer = new byte[fileUpload.InputStream.Length];
        fileUpload.InputStream.Read(buffer, 0, buffer.Length);
        fs.Write(buffer, 0, buffer.Length);
    }
    return uploadedFilePath;
}   

这是我的例外。
