Azure AD Graph API 目录架构扩展

Question

我目前正在尝试使用 Graph 客户端库版本 2.0 与我的 Azure Active Directory 进行交互。我想为用户添加一个新属性，所以我需要使用 Schema Extensions。我按照这里的教程：http://justazure.com/azure-active-directory-part-6-schema-extensions，以及这里的示例代码：https://github.com/AzureADSamples/ConsoleApp-GraphAPI-DotNet。

我的代码：

public async Task setAccountNumber(string UserName, String AccountNumber)
    {
        ////Register an Extension Property in Azure AD which is the account number
        ////Define the account number property
        //ExtensionProperty accountNumber = new ExtensionProperty()
        //{
        //    Name = "AccountNumber",
        //    DataType = "String",
        //    TargetObjects = { "User" }
        //};

        //// Get a reference to our application
        //Microsoft.Azure.ActiveDirectory.GraphClient.Application app =
        //                (Microsoft.Azure.ActiveDirectory.GraphClient.Application)activeDirectoryClient.Applications.Where(
        //    a => a.AppId == Constants.ClientId).ExecuteSingleAsync().Result;

        //// Register the extension property
        //app.ExtensionProperties.Add(accountNumber);
        //await app.UpdateAsync();


        ExtensionProperty accountNumber = new ExtensionProperty()
        {
            Name = "AccountNumber",
            DataType = "String",
            TargetObjects = { "User" }
        };

        //Get the user
        User user = (User)activeDirectoryClient.Users.Where(u => u.UserPrincipalName.Equals(
            UserName, StringComparison.CurrentCultureIgnoreCase)).ExecuteSingleAsync().Result;

        //Set the Account Number property
        if (user != null)
        {
            user.SetExtendedProperty(accountNumber.Name, AccountNumber);
            await user.UpdateAsync();
            // Save the extended property value to Azure AD.
            //user.GetContext().SaveChanges();
        }

        // Retrieve the extension property value for a user for test use only!
        IReadOnlyDictionary<string, object> extendedProperties = user.GetExtendedProperties();
        object extendedProperty = extendedProperties["AccountNumber"];
}

我使用注释行创建了一个新的扩展属性，即用户的帐号。并且我使用下面的代码找到了一个新用户并设置了这个用户的账号。

但是，我得到了这个错误：

{"odata.error": {
  "code":"Request_BadRequest",
  "message": {
    "lang":"en",
    "value":"One or more extension property values specified are invalid."
  },
  "values":null}}

在线：await user.UpdateAsync();

堆栈跟踪：

[DataServiceClientException: {"odata.error":{"code":"Request_BadRequest","message":{"lang":"en","value":"One or more extension property values specified are invalid."},"values":null}}]

感谢任何帮助。

所以我设法重现了这个问题。基本上，错误消息意味着服务找不到您正在寻找的扩展属性。您的代码的问题是您将“AccountNumber”指定为扩展名。然而，扩展的格式为“extension_appId_extensionName”以确保扩展名的唯一性。 注意：appId 这里是您的应用的 appId（又名 clientId）GUID，但没有破折号 - 即 xxxx-xxx-xxx 变为 xxxxxxxxxx。

因此，最简单的做法是使用上述语法构造扩展属性名称 - 在您的情况下，它将是“extension_appId_AccountName”，在此处替换您的应用程序的 appId/clientId。

我认为这可能是因为您复制了我们的示例，然后完整的扩展名在内存中，因为在示例中我们刚刚创建了扩展，所以我们只是从那里使用它。我可能会将示例更改为“构造”完整的扩展名（按照上面的语法）。
