rest - 从 SharePoint 文件中删除多租户 Web 应用程序中的 AIP 保护

Question

我正在尝试RemoveProtection在多租户 Web 应用程序中使用 Azure AD App。我无法弄清楚如何。我目前的设置是：

1. 注册了具有以下权限的 Azure AD 应用

2. 使用以下代码IAuthDelegate

       AuthenticationContext authContext = new AuthenticationContext(authority, tokenCache);
       AuthenticationResult result;
   
       var clientCred = new ClientCredential(appInfo.ApplicationId, clientSecret);
       result = authContext.AcquireTokenAsync(resource, clientCred).Result;
   
   
       return result.AccessToken;`
   

3. 主控制器中的代码

     string name = User.Identity.Name;
   
       // Set path to bins folder.
       var path = Path.Combine(
             Directory.GetParent(Path.GetDirectoryName(new Uri(System.Reflection.Assembly.GetExecutingAssembly().CodeBase).LocalPath)).FullName,
              Environment.Is64BitProcess ? "bin\\x64" : "bin\\x86");
   
       MIP.Initialize(MipComponent.File, path);
   
       ApplicationInfo appInfo = new ApplicationInfo()
       {
   
           ApplicationId = clientId,
           ApplicationName = appName,
           ApplicationVersion = appVersion
       };
   
       AuthDelegateImplementation authDelegate = new AuthDelegateImplementation(appInfo);
   
       var profileSettings = new FileProfileSettings(mipPath, false, authDelegate, new ConsentDelegateImplementation(), appInfo, LogLevel.Trace);
   
       var fileProfile = Task.Run(async () => await MIP.LoadFileProfileAsync(profileSettings)).Result;
   
       var engineSettings = new FileEngineSettings(name, "", "en-US");
       engineSettings.Identity = new Identity(name);
   
       var fileEngine = Task.Run(async () => await fileProfile.AddEngineAsync(engineSettings)).Result;
   

我的问题是如何使用它从 SharePoint 中的文档中删除 AIP？此外，是否有任何 REST API 用于此？
