Understand the code

Introduction

Solution Component Diagram

The top layer of the solution contains a web application and a WebJob console application.

The middle layer contains two class library projects.

The bottom layers contains the three data sources.

EDUGraphAPI.Web

This web application is based on an ASP.NET MVC project template with the Individual User Accounts option selected.

The following files were created by the MVC template, and only minor changes were made:

  1. /App_Start/Startup.Auth.Identity.cs (The original name is Startup.Auth.cs)
  2. /Controllers/AccountController.cs

This sample project uses ASP.NET Identity and Owin. These two technologies make different methods of authentication coexist easily. Familiarity with these components, in addition to ASP.NET MVC, is essential to understanding this sample.

Below are important class files used in this web project:

File Description
/App_Start/Startup.Auth.AAD.cs Integrates with Azure Active Directory authentication
/Controllers/AdminController.cs Contains the administrative actions:
admin consent, manage linked accounts and install the app.
/Controllers/LinkController.cs Contains the actions to link AD and local user accounts
/Controllers/SchoolsController.cs Contains the actions to present education data

This web application is a multi-tenant app. In the AAD, we enabled the option:

Users from any Azure Active Directory tenant can access this app. As this app uses some application permissions, an administrator of the tenant should sign up (consent) first. Otherwise, users would be an error:

For more information, see Build a multi-tenant SaaS web application using Azure AD & OpenID Connect.

EDUGraphAPI.SyncData

This is the WebJob used to sync user data. In the Functions.SyncUsersAsync method, UserSyncService from EDUGraphAPI.Common project is used.

The project was created to demonstrate differential query. Please check Differential query section for more details.

EDUGraphAPI.Common

The class library project is used both the EDUGraphAPI.Web and EDUGraphAPI.SyncData.

The table below shows the folders in the project:

Folder Description
/Data Contains ApplicationDbContext and entity classes
/DataSync Contains the UserSyncSerextensionsvice class which is used by the EDUGraphAPI.SyncData WebJob
/DifferentialQuery Contains the DifferentialQueryService class which is used to send differential query and parse the result.
/Extensions Contains lots of extension methods which simplify coding the make code easy to read
/Utils Contains the wide used class AuthenticationHelper.cs

Microsoft.Education

This project encapsulates the Schools REST API client. The core class in this project is EducationServiceClient.

Data Access and Data Models

ASP.NET Identity uses Entity Framework Code First to implement all of its persistence mechanisms. Package Microsoft.AspNet.Identity.EntityFramework is consumed for this.

In this sample, ApplicationDbContext is created for access to the database. It inherited from IdentityDbContext which is defined in the NuGet package mentioned above.

Below are the important Data Models (and their important properties) that used in this sample:

ApplicationUsers

Inherited from IdentityUser.

Property Description
Organization The tenant of the user. For local unlinked user, its value is null
O365UserId Used to link with an Office 365 account
O365Email The Email of the linked Office 365 account
JobTitle Used for demonstrating differential query
Department Used for demonstrating differential query
Mobile Used for demonstrating differential query
FavoriteColor Used for demonstrating local data

Organizations

A row in this table represents a tenant in AAD.

Property Description
TenantId Guid of the tenant
Name Name of the tenant
IsAdminConsented Is the tenant consented by any admin

Admin Consent Flow

App-only permissions always require a tenant administrator’s consent. If your application requests an app-only permission and a user tries to sign in to the application, an error message will be displayed saying the user isn’t able to consent.

Certain delegated permissions also require a tenant administrator’s consent. For example, the ability to write back to Azure AD as the signed in user requires a tenant administrator’s consent. Like app-only permissions, if an ordinary user tries to sign in to an application that requests a delegated permission that requires administrator consent, your application will receive an error. Whether or not a permission requires admin consent is determined by the developer that published the resource, and can be found in the documentation for the resource.

If your application uses permissions that require admin consent, you need to have a gesture such as a button or link where the admin can initiate the action. The request your application sends for this action is a usual OAuth2/OpenID Connect authorization request, but that also includes the prompt=admin_consent query string parameter. Once the admin has consented and the service principal is created in the customer’s tenant, subsequent sign-in requests do not need the prompt=admin_consent parameter. Since the administrator has decided the requested permissions are acceptable, no other users in the tenant will be prompted for consent from that point forward.

Authentication Flows

There are 4 authentication flows in this project.

The first 2 flows (Local Login/O365 Login) enable users to login in with either a local account or an Office 365 account, then link to the other type account. This procedure is implemented in the LinkController.

Local Login Authentication Flow

O365 Login Authentication Flow

Admin Login Authentication Flow

This flow shows how an administrator logs into the system and performs administrative operations.

After logging into the app with an office 365 account, the administrator will be asked to link to local account. This step is not required and can be skipped.

As we mentioned earlier, the web app is a multi-tenant app which uses some application permissions, so an administrator of the tenant should consent the tenant first.

This flow is implemented in AdminController.

Application Authentication Flow

This flow in implemented in the SyncData WebJob.

An X509 certificate is used. For more details, please check the following links:

Two Kinds of Graph API

There are two distinct Graph APIs used in this sample:

Azure AD Graph API Microsoft Graph API
Description The Azure Active Directory Graph API provides programmatic access to Azure Active Directory through REST API endpoints. Apps can use the Azure AD Graph API to perform create, read, update, and delete (CRUD) operations on directory data and directory objects, such as users, groups, and organizational contacts A unified API that also includes APIs from other Microsoft services like Outlook, OneDrive, OneNote, Planner, and Office Graph, all accessed through a single endpoint with a single access token.
Client Install-Package Microsoft.Azure.ActiveDirectory.GraphClient Install-Package Microsoft.Graph
End Point https://graph.windows.net https://graph.microsoft.com
API Explorer https://graphexplorer.cloudapp.net/ https://graph.microsoft.io/graph-explorer

In this sample we use the classes below, which are based on a common interface, to demonstrate how the APIs are related:

The IGraphClient interface defines two method: GeCurrentUserAsync and GetTenantAsync.

MSGraphClient implement the IGraphClient interface with Microsoft Graph client libraries.

The interface and the graph client class resides in /Services/GraphClients folder of the web app. Some code is highlighted below to show how to get user and tenant.

Microsoft Graph - MSGraphClient.cs

        public async Task<UserInfo> GetCurrentUserAsync()
        {
            var me = await graphServiceClient.Me.Request()
                .Select("id,givenName,surname,userPrincipalName,assignedLicenses")
                .GetAsync();
            return new UserInfo
            {
                Id = me.Id,
                GivenName = me.GivenName,
                Surname = me.Surname,
                Mail = me.Mail,
                UserPrincipalName = me.UserPrincipalName,
                Roles = await GetRolesAsync(me)
            };
        }
        public async Task<TenantInfo> GetTenantAsync(string tenantId)
        {
            var tenant = await graphServiceClient.Organization[tenantId].Request().GetAsync();
            return new TenantInfo
            {
                Id = tenant.Id,
                Name = tenant.DisplayName
            };
        }

Note that in app registration settings, permissions for each Graph API are configured separately:

Office 365 Education API

Office 365 Education APIs help extract data from your Office 365 tenant which has been synced to the cloud by Microsoft School Data Sync. These results provide information about schools, sections, teachers, students and rosters. The Schools REST API provides access to school entities in Office 365 for Education tenants.

In the sample, the Microsoft.Education Class Library project was created to encapsulate Office 365 Education API.

EducationServiceClient is the core class of the library. With it we can get education data easily.

Get schools

public async Task<School[]> GetSchoolsAsync()
{
    var schools = await HttpGetArrayAsync<EducationSchool>("education/schools");
    return schools.ToArray();

}

Get sections

 public async Task<ArrayResult<EducationClass>> GetAllClassesAsync(string schoolId, string nextLink)
{
           if (string.IsNullOrEmpty(schoolId))
            {
                return new ArrayResult<EducationClass>
                {
                    Value = new EducationClass[] { },
                     NextLink = nextLink
                };
            }
            else
            {
                var relativeUrl = $"education/schools/{schoolId}/classes?$top=12";
                return await HttpGetArrayAsync<EducationClass>(relativeUrl, nextLink);

        
            }

}
        public async Task<EducationClass[]> GetMyClassesAsync(bool loadMembers = false, string expandField = "members")
        {
            var relativeUrl = $"education/me/classes";

            // Important to do this in one round trip, not in a sequence of calls.
            if (loadMembers)
            {
                relativeUrl += "?$expand=" + expandField;
            }

            var memberOf = await HttpGetArrayAsync<EducationClass>(relativeUrl);
            var classes = memberOf.ToArray();

            return classes;
        }

Below are some screenshots of the sample app that show the education data.

In EducationServiceClient, three private methods prefixed with HttpGet were created to simplify the invoking of REST APIs.

  • HttpGetAsync: sends a http GET request to the target endpoint, and returns the JSON response string. An access token is included in the bearer authentication header.
  • HttpGetObjectAsync: deserializes the JSON string returned by HttpGetAsync to the target type T, and return the result object.
  • HttpGetArrayAsync: deserializes the JSON string returned by HttpGetAsync to the target array type T[], and return the array.

Differential Query

A differential query request returns all changes made to specified entities during the time between two consecutive requests. For example, if you make a differential query request an hour after the previous differential query request, only the changes made during that hour will be returned. This functionality is especially useful when synchronizing tenant directory data with an application’s data store.

The related code is in the following two folders of the EDUGraphAPI.Common project:

  • /DifferentialQuery: contains classes to send differential query and parse differential result.
  • /DataSync: contains classes that are used to demonstrate how to sync users.

Note that classes in DifferentialQuery folder use some advanced .NET technologies. Please focus on the usage of these classes rather than their implementation details.

To sync users, we defined the User class:

public class User
{
    public string ObjectId { get; set; }
    public virtual string JobTitle { get; set; }
    public virtual string Department { get; set; }
    public virtual string Mobile { get; set; }
}

Notice that the changeable properties JobTitle, Department, Mobile are virtual. Classes in DifferentialQuery folder will create a proxy type for the User type and override these virtual properties for change tracking.

In UserSyncService class, we demonstrate how to use the DifferentialQueryService to send differential query and get differential result.

var differentialQueryService = new DifferentialQueryService(/**/);
DeltaResult<Delta<User>> result = await differentialQueryService.QueryAsync<User>(url);

And how to update (or delete) users in local database with the delta result:

foreach (var differentialUser in result.Items)
    await UpdateUserAsync(differentialUser);
//...
private async Task UpdateUserAsync(Delta<User> differentialUser) { /**/ }

DataSyncRecord data model is used to persistent deltaLinks.

Below is the log generated by the SyncData WebJob:

Filters

In the /Infrastructure folder of the web project, there are several FilterAttributes.

EduAuthorizeAttribute

This is an authorization filter, inherited from AuthorizeAttribute.

It was created to allow the web app to redirect users to the proper login page in our multi-authentication-method scenario.

We overrided the HandleUnauthorizedRequest method to redirect the user to /Account/Login:

protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
{
    filterContext.Result = new RedirectResult("/Account/Login");
}

HandleAdalExceptionAttribute

The AuthenticationHelper class exposes lots of methods that return access tokens or instance of an API client. Most of these methods invoke AuthenticationContext.AcquireTokenSilentAsync internally. Usually, AcquireTokenSilentAsync gets the access token successfully, as tokens are cached in the database by ADALTokenCache.

In some situations, like the cached token being expired or a new resource token is requested, AcquireTokenSilentAsync will throw AdalException.HandleAdalExceptionAttribute is required to handle AdalException, and navigate the user to the authentication endpoint to get a new token.

In some cases, we will redirect the user directly to the authentication endpoint by invoking:

filterContext.HttpContext.GetOwinContext().Authentication.Challenge(
   new AuthenticationProperties { RedirectUri = requestUrl },
   OpenIdConnectAuthenticationDefaults.AuthenticationType);

And in other cases, we want to show the user the page below to tell the user the reason why he got redirected, especially for a user who logged in with an local account.

We use a switch to control this. The switch value is retrieved by:

//public static readonly string ChallengeImmediatelyTempDataKey = "ChallengeImmediately";
var challengeImmediately = filterContext.Controller.TempData[ChallengeImmediatelyTempDataKey];

If the value is true, we will redirect the user to the authentication endpoint immediately. Otherwise, the page above will be shown first, and user clicks the Login button to proceed.

LinkedOrO365UsersOnlyAttribute

This is another authorization filter. With it we can only allow linked users or Office 365 users to visit the protected controllers/actions.

protected override bool AuthorizeCore(HttpContextBase httpContext)
{
    var applicationService = DependencyResolver.Current.GetService<ApplicationService>();
    var user = applicationService.GetUserContext();
    return user.AreAccountsLinked || user.IsO365Account;
}

For unauthorized user, we will show them the NoAccess page:

protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
{
    filterContext.Result = new ViewResult { ViewName = "NoAccess" };
}

So far, It is only used on the SchoolsController.
