[英]How to add a SharePoint tab using Microsoft Graph API and Graph Client?
[英]How to mock Microsoft Graph API SDK Client?
我在我的項目中使用了 Microsoft Graph SDK 來調用圖形 API,為此我需要使用 GraphServiceClient。 要使用 GraphServiceClient,我必須添加一些輔助類,其中 SDKHelper 是具有 GetAuthenticatedClient() 方法的靜態類。 由於被測方法與靜態的 SDKHelper 緊密耦合,因此我創建了一個服務類並注入了依賴項。
下面是控制器和方法,
public class MyController
{
private IMyServices _iMyServices { get; set; }
public UserController(IMyServices iMyServices)
{
_iMyServices = iMyServices;
}
public async Task<HttpResponseMessage> GetGroupMembers([FromUri]string groupID)
{
GraphServiceClient graphClient = _iMyServices.GetAuthenticatedClient();
IGroupMembersCollectionWithReferencesPage groupMembers = await _iMyServices.GetGroupMembersCollectionWithReferencePage(graphClient, groupID);
return this.Request.CreateResponse(HttpStatusCode.OK, groupMembers, "application/json");
}
}
服務類,
public class MyServices : IMyServices
{
public GraphServiceClient GetAuthenticatedClient()
{
GraphServiceClient graphClient = new GraphServiceClient(
new DelegateAuthenticationProvider(
async (requestMessage) =>
{
string accessToken = await SampleAuthProvider.Instance.GetAccessTokenAsync();
requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", accessToken);
requestMessage.Headers.Add("Prefer", "outlook.timezone=\"" + TimeZoneInfo.Local.Id + "\"");
}));
return graphClient;
}
public async Task<IGraphServiceGroupsCollectionPage> GetGraphServiceGroupCollectionPage(GraphServiceClient graphClient)
{
return await graphClient.Groups.Request().GetAsync();
}
}
我在為上述服務類方法編寫單元測試用例時遇到了挑戰,以下是我的單元測試代碼:
public async Task GetGroupMembersCollectionWithReferencePage_Success()
{
GraphServiceClient graphClient = GetAuthenticatedClient();
IGraphServiceGroupsCollectionPage groupMembers = await graphClient.Groups.Request().GetAsync();
Mock<IUserServices> mockIUserService = new Mock<IUserServices>();
IGraphServiceGroupsCollectionPage expectedResult = await mockIUserService.Object.GetGraphServiceGroupCollectionPage(graphClient);
Assert.AreEqual(expectedResult, groupMembers);
}
在上面的測試用例中,第 4 行引發異常 - 消息:“Connect3W.UserMgt.Api.Helpers.SampleAuthProvider”的類型初始值設定項引發異常。 內部異常消息:值不能為空。 參數名稱:格式
誰能建議我如何使用 MOQ 來模擬上面的代碼或任何其他方法來完成測試用例?
不要嘲笑你不擁有的東西。 GraphServiceClient
應被視為第 3 方依賴項,並應封裝在您控制的抽象之后
您嘗試這樣做,但仍在泄漏實現問題。
該服務可以簡化為
public interface IUserServices {
Task<IGroupMembersCollectionWithReferencesPage> GetGroupMembers(string groupID);
}
和實施
public class UserServices : IUserServices {
GraphServiceClient GetAuthenticatedClient() {
var graphClient = new GraphServiceClient(
new DelegateAuthenticationProvider(
async (requestMessage) =>
{
string accessToken = await SampleAuthProvider.Instance.GetAccessTokenAsync();
requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", accessToken);
requestMessage.Headers.Add("Prefer", "outlook.timezone=\"" + TimeZoneInfo.Local.Id + "\"");
}));
return graphClient;
}
public Task<IGroupMembersCollectionWithReferencesPage> GetGroupMembers(string groupID) {
var graphClient = GetAuthenticatedClient();
return graphClient.Groups[groupID].Members.Request().GetAsync();
}
}
這也會導致控制器被簡化
public class UserController : ApiController {
private readonly IUserServices service;
public UserController(IUserServices myServices) {
this.service = myServices;
}
public async Task<IHttpActionResult> GetGroupMembers([FromUri]string groupID) {
IGroupMembersCollectionWithReferencesPage groupMembers = await service.GetGroupMembers(groupID);
return Ok(groupMembers);
}
}
現在為了測試控制器,您可以輕松地模擬抽象以按預期運行,以便完成測試,因為控制器與GraphServiceClient
3rd 方依賴項完全分離,並且可以單獨測試控制器。
[TestClass]
public class UserControllerShould {
[TestMethod]
public async Task GetGroupMembersCollectionWithReferencePage_Success() {
//Arrange
var groupId = "12345";
var expectedResult = Mock.Of<IGroupMembersCollectionWithReferencesPage>();
var mockService = new Mock<IUserServices>();
mockService
.Setup(_ => _.GetGroupMembers(groupId))
.ReturnsAsync(expectedResult);
var controller = new UserController(mockService.Object);
//Act
var result = await controller.GetGroupMembers(groupId) as System.Web.Http.Results.OkNegotiatedContentResult<IGroupMembersCollectionWithReferencesPage>;
//Assert
Assert.IsNotNull(result);
var actualResult = result.Content;
Assert.AreEqual(expectedResult, actualResult);
}
}
@Nkosi 的替代解決方案。 使用構造函數public GraphServiceClient(IAuthenticationProvider authenticationProvider, IHttpProvider httpProvider = null);
我們可以模擬實際提出的請求。
下面的完整示例。
我們的GraphApiService
使用IMemoryCache
來緩存來自 ADB2C 的AccessToken
和用戶,用於 HTTP 請求的IHttpClientFactory
和來自appsettings.json
Settings
。
https://docs.microsoft.com/en-us/aspnet/core/performance/caching/memory?view=aspnetcore-5.0
https://docs.microsoft.com/en-us/aspnet/core/fundamentals/http-requests?view=aspnetcore-5.0
public class GraphApiService
{
private readonly IHttpClientFactory _clientFactory;
private readonly IMemoryCache _memoryCache;
private readonly Settings _settings;
private readonly string _accessToken;
public GraphApiService(IHttpClientFactory clientFactory, IMemoryCache memoryCache, Settings settings)
{
_clientFactory = clientFactory;
_memoryCache = memoryCache;
_settings = settings;
string graphApiAccessTokenCacheEntry;
// Look for cache key.
if (!_memoryCache.TryGetValue(CacheKeys.GraphApiAccessToken, out graphApiAccessTokenCacheEntry))
{
// Key not in cache, so get data.
var adb2cTokenResponse = GetAccessTokenAsync().GetAwaiter().GetResult();
graphApiAccessTokenCacheEntry = adb2cTokenResponse.access_token;
// Set cache options.
var cacheEntryOptions = new MemoryCacheEntryOptions()
.SetAbsoluteExpiration(TimeSpan.FromSeconds(adb2cTokenResponse.expires_in));
// Save data in cache.
_memoryCache.Set(CacheKeys.GraphApiAccessToken, graphApiAccessTokenCacheEntry, cacheEntryOptions);
}
_accessToken = graphApiAccessTokenCacheEntry;
}
public async Task<List<Adb2cUser>> GetAllUsersAsync(bool refreshCache = false)
{
if (refreshCache)
{
_memoryCache.Remove(CacheKeys.Adb2cUsers);
}
return await _memoryCache.GetOrCreateAsync(CacheKeys.Adb2cUsers, async (entry) =>
{
entry.SetAbsoluteExpiration(TimeSpan.FromHours(1));
var authProvider = new AuthenticationProvider(_accessToken);
GraphServiceClient graphClient = new GraphServiceClient(authProvider, new HttpClientHttpProvider(_clientFactory.CreateClient()));
var users = await graphClient.Users
.Request()
.GetAsync();
return users.Select(user => new Adb2cUser()
{
Id = Guid.Parse(user.Id),
GivenName = user.GivenName,
FamilyName = user.Surname,
}).ToList();
});
}
private async Task<Adb2cTokenResponse> GetAccessTokenAsync()
{
var client = _clientFactory.CreateClient();
var kvpList = new List<KeyValuePair<string, string>>();
kvpList.Add(new KeyValuePair<string, string>("grant_type", "client_credentials"));
kvpList.Add(new KeyValuePair<string, string>("client_id", _settings.AzureAdB2C.ClientId));
kvpList.Add(new KeyValuePair<string, string>("scope", "https://graph.microsoft.com/.default"));
kvpList.Add(new KeyValuePair<string, string>("client_secret", _settings.AzureAdB2C.ClientSecret));
#pragma warning disable SecurityIntelliSenseCS // MS Security rules violation
var req = new HttpRequestMessage(HttpMethod.Post, $"https://login.microsoftonline.com/{_settings.AzureAdB2C.Domain}/oauth2/v2.0/token")
{ Content = new FormUrlEncodedContent(kvpList) };
#pragma warning restore SecurityIntelliSenseCS // MS Security rules violation
using var httpResponse = await client.SendAsync(req);
var response = await httpResponse.Content.ReadAsStringAsync();
httpResponse.EnsureSuccessStatusCode();
var adb2cTokenResponse = JsonSerializer.Deserialize<Adb2cTokenResponse>(response);
return adb2cTokenResponse;
}
}
public class AuthenticationProvider : IAuthenticationProvider
{
private readonly string _accessToken;
public AuthenticationProvider(string accessToken)
{
_accessToken = accessToken;
}
public Task AuthenticateRequestAsync(HttpRequestMessage request)
{
request.Headers.Add("Authorization", $"Bearer {_accessToken}");
return Task.CompletedTask;
}
}
public class HttpClientHttpProvider : IHttpProvider
{
private readonly HttpClient http;
public HttpClientHttpProvider(HttpClient http)
{
this.http = http;
}
public ISerializer Serializer { get; } = new Serializer();
public TimeSpan OverallTimeout { get; set; } = TimeSpan.FromSeconds(300);
public void Dispose()
{
}
public Task<HttpResponseMessage> SendAsync(HttpRequestMessage request)
{
return http.SendAsync(request);
}
public Task<HttpResponseMessage> SendAsync(HttpRequestMessage request,
HttpCompletionOption completionOption,
CancellationToken cancellationToken)
{
return http.SendAsync(request, completionOption, cancellationToken);
}
}
然后我們在各種Controllers
使用GraphApiService
。 下面是一個簡單的CommentController
示例。 不包括CommentService
但無論如何示例都不需要它。
[Route("api/[controller]")]
[ApiController]
[Authorize]
public class CommentController : ControllerBase
{
private readonly CommentService _commentService;
private readonly GraphApiService _graphApiService;
public CommentController(CommentService commentService, GraphApiService graphApiService)
{
_commentService = commentService;
_graphApiService = graphApiService;
}
[HttpGet("{rootEntity}/{id}")]
public ActionResult<IEnumerable<CommentDto>> Get(RootEntity rootEntity, int id)
{
var comments = _commentService.Get(rootEntity, id);
var users = _graphApiService.GetAllUsersAsync().GetAwaiter().GetResult();
var commentDtos = new List<CommentDto>();
foreach (var comment in comments)
{
commentDtos.Add(CommonToDtoMapper.MapCommentToCommentDto(comment, users));
}
return Ok(commentDtos);
}
[HttpPost("{rootEntity}/{id}")]
public ActionResult Post(RootEntity rootEntity, int id, [FromBody] string message)
{
_commentService.Add(rootEntity, id, message);
_commentService.SaveChanges();
return Ok();
}
}
由於我們使用自己的IAuthenticationProvider
和IHttpProvider
我們可以根據調用的 URI 來模擬IHttpClientFactory
。 下面完整的測試示例,檢查mockMessageHandler.Protected()
以查看請求是如何mockMessageHandler.Protected()
。 為了找到確切的請求,我們查看了文檔。 例如var users = await graphClient.Users.Request().GetAsync();
相當於GET https://graph.microsoft.com/v1.0/users
。
https://docs.microsoft.com/en-us/graph/api/user-list?view=graph-rest-1.0&tabs=http#request
public class CommentControllerTest : SeededDatabase
{
[Fact]
public void Get()
{
using (var context = new ApplicationDbContext(_dbContextOptions))
{
var controller = GeCommentController(context);
var result = controller.Get(RootEntity.Question, 1).Result;
var okResult = Assert.IsType<OkObjectResult>(result);
var returnValue = Assert.IsType<List<CommentDto>>(okResult.Value);
Assert.Equal(2, returnValue.Count());
}
}
[Theory]
[MemberData(nameof(PostData))]

{
using (var context = new ApplicationDbContext(_dbContextOptions))
{
var controller = GeCommentController(context);
var result = controller.Post(rootEntity, id, message);

var comment = context.Comments.First(x => x.Text == message);
if(rootEntity == RootEntity.Question)
{
Assert.Equal(comment.QuestionComments.First().QuestionId, id);
}
}
}
public static IEnumerable<object[]> PostData()
{
return new List<object[]>
{
new object[]

};
}
