图形客户端中的 Azure 架构扩展

Question

无论我尝试什么，我都无法在 User 对象上设置扩展属性，这是一段可重现的代码:

public async Task CleanTest(string extName)
      {
         ExtensionProperty ep = new ExtensionProperty
         {
            Name = extName,
            DataType = "String",
            TargetObjects = { "User" }
         };

         App app = (App)(await _client.Applications.Where(a => a.AppId == _managementAppClientId).ExecuteSingleAsync());
         app.ExtensionProperties.Add(ep);
         await app.UpdateAsync();

         GraphUser user = (GraphUser)(await _client.Users.Where(u => u.UserPrincipalName.Equals("email")).ExecuteSingleAsync());
         string propName = FormatExtensionPropertyName(extName); //formats properly as extesion_xxx_name
         user.SetExtendedProperty(propName, "testvalue");
         //user.SetExtendedProperty(extName, "testvalue");
         await user.UpdateAsync(); // fails here
      }

根据 Fiddler 的 user.UpdateAsync() 甚至不会消失，并且应用程序失败并出现异常:

“类型“Microsoft.Azure.ActiveDirectory.GraphClient.Internal.User”上不存在属性“extension_e206e28ff36244b19bc56c01160b9cf0_UserEEEqdbtgd3ixx2”。请确保仅使用该类型定义的属性名称。”

此问题也在此处进行跟踪: https://github.com/Azure-Samples/active-directory-dotnet-graphapi-console/issues/28

对于那些想要使用 5.7 版 OData 库而不是重定向到 v5.6.4 版本的用户，我有针对此错误的替代解决方法。

添加请求管道配置处理程序。

// initialize in the usual way
ActiveDirectoryClient activeDirectoryClient = 
  AuthenticationHelper.GetActiveDirectoryClientAsApplication();
// after initialization add a handler to the request pipline configuration.
activeDirectoryClient.Context
  .Configurations.RequestPipeline
  .OnMessageWriterSettingsCreated(UndeclaredPropertyHandler);

在处理程序中，将编写器设置上的 ODataUndeclaredPropertyBehaviorKinds 值更改为 SupportUndeclaredValueProperty。

private static void UndeclaredPropertyHandler(MessageWriterSettingsArgs args)
{
  var field = args.Settings.GetType().GetField("settings", 
    BindingFlags.NonPublic | BindingFlags.Instance);
  var settingsObject = field?.GetValue(args.Settings);
  var settings = settingsObject as ODataMessageWriterSettings;
  if (settings != null)
  {
    settings.UndeclaredPropertyBehaviorKinds = 
       ODataUndeclaredPropertyBehaviorKinds.SupportUndeclaredValueProperty;
  }
}
