PowerBI Embedded: DeleteUserAsAdminAsync returns unauthorized - powerbi

Receiving an unauthorized response when trying to remove a user from a workspace (group). I'm using the .Net SDK method DeleteUserAsAdminAsync. I tried the DeleteUserInGroupAsync method with the same result. I've had no trouble retrieving groups, reports, even adding users to groups using the same authentication code shown below. I'm quite stumped.
public async Task<ResultObject> RemoveUsersFromWorkspaces(List<PowerBIWorkspace> powerBIWorkspaces)
{
// Authenticate using created credentials
AuthenticationResult authenticationResult = null;
authenticationResult = await DoAuthentication("CustomerAppRegistration");
var tokenCredentials =
new TokenCredentials(authenticationResult.AccessToken, "Bearer");
using (var client = new PowerBIClient(
new Uri("https://api.powerbi.com/"), tokenCredentials))
{
try
{
foreach (var wksp in powerBIWorkspaces)
{
// Remove the user to the workspace.
await client.Groups.DeleteUserAsAdminAsync(new Guid(wksp.WorkspaceId), wksp.UserEmail);
}
}
catch (Exception ex)
{
var errorObject = new ResultObject();
errorObject.Success = false;
errorObject.ErrorMessage = ex.Message;
return errorObject;
}
}
var resultObject = new ResultObject();
resultObject.Success = true;
resultObject.ErrorMessage = "";
return resultObject;
}
private const string AuthorityFormat = "https://login.microsoftonline.com/{0}/v2.0";
private const string MSGraphScope = "https://analysis.windows.net/powerbi/api/.default";
private async Task<AuthenticationResult> DoAuthentication(string appRegistrationSection)
{
var config = new ConfigurationBuilder()
.SetBasePath(AppDomain.CurrentDomain.BaseDirectory)
.AddJsonFile("appsettings.json").Build();
//var section = config.GetSection(nameof(AppRegistration));
var section = config.GetSection(appRegistrationSection);
var appRegistration = section.Get<AppRegistration>();
TenantID = appRegistration.TenantId;
ClientID = appRegistration.ClientId;
ClientSecret = appRegistration.ClientSecret;
IConfidentialClientApplication daemonClient;
daemonClient = ConfidentialClientApplicationBuilder.Create(ClientID)
.WithAuthority(string.Format(AuthorityFormat, TenantID))
.WithClientSecret(ClientSecret)
.Build();
AuthenticationResult authResult =
await daemonClient.AcquireTokenForClient(new[] { MSGraphScope }).ExecuteAsync();
return authResult;

Use Aws4RequestSigner to sign PAAPI 5 Request

I'm trying to use Aws4RequestSigner in a VS2015 form to sign a search request to Amazon PAAPI.
https://www.nuget.org/packages/Aws4RequestSigner/
I get this response from the API:
{"__type":"com.amazon.paapi5#IncompleteSignatureException","Errors":[{"Code":"IncompleteSignature","Message":"The request signature did not include all of the required components. If you are using an AWS SDK, requests are signed for you automatically; otherwise, go to https://webservices.amazon.com/paapi5/documentation/sending-request.html#signing."}]}
private async void Form1_Load(object sender, EventArgs e)
{
_accessKey = "x";
_secretKey = "x";
_service = "ProductAdvertisingAPIv1";
_region = "us-east-1";
_requestUri = new Uri("https://webservices.amazon.com/paapi5/searchitems");
var payload = new
{
Keywords = "Harry",
Marketplace = "www.amazon.com",
PartnerTag = "x0d-20",
PartnerType = "Associates",
Resources = new string[] { "Images.Primary.Small", "ItemInfo.Title", "Offers.Listings.Price" },

};
string jsonString = JsonConvert.SerializeObject(payload);
var content = new StringContent(jsonString, Encoding.UTF8, "application/json");

content.Headers.Add("x-amz-date", xAmzDate);

};
request.Headers.Host = "webservices.amazon.com";
var contentType = new MediaTypeHeaderValue("application/json");
contentType.CharSet = "utf-8";
request.Content.Headers.ContentType = contentType;
var signer = new AWS4RequestSigner(_accessKey, _secretKey);
request = await signer.Sign(request, _service, _region);
try
{
var client = new HttpClient();
var response = await client.SendAsync(request);
if (!response.IsSuccessStatusCode)
{
var error = await response.Content.ReadAsStringAsync();
}
// response.EnsureSuccessStatusCode();
txtDisplay.Text = await response.Content.ReadAsStringAsync();
}
catch (HttpRequestException ex)
{
string error = ex.Message;
txtDisplay.Text = error;
}
}
private string GetTimeStamp()
{
return DateTime.UtcNow.ToString("yyyyMMdd\\THHmmss\\Z");
}
It could be that the headers are being added incorrectly or Aws4RequestSigner is simply outdated.

Connect to Azure Text Analytics from Console App without await

I am trying to call an Azure API (Text Analytics API) from a C# console application with a HttpRequest and I do not want to use any DLLs or await
but using the below snippet I am receiving "Bad Request". Can someone help me where it is going wrong.
public static void ProcessText()

Hi All, I could able to get the API output using the above approach

PowerBI Embedded V2 Direct Query - Azure Sql credentials not updated programatically

I'm programatically creating a workspace and importing a Direct-Query report into PowerBI Embedded V2. Everything works fine except the report data source credentials which are not updated.
This is the code for the import flow:
await _powerBIService.ImportPbixAsync(newWorkspaceId, reportNameWithoutExtension, fileStream);
Console.WriteLine("Imported report {0} for {1} ({2})", reportNameWithoutExtension, persona.Name, persona.Id);
string datasetId = null;
while (datasetId == null)
{
//get DataSource Id
Thread.Sleep(5000);
datasetId = await _powerBIService.GetDatasetIdFromWorkspace(newWorkspaceId, reportNameWithoutExtension);
}
//update the connection details
await _powerBIService.UpdateConnectionAsync(newWorkspaceId, datasetId, persona.SQLUser, persona.SQLPassword);
Console.WriteLine("Updated connection details for dataset {0}", reportNameWithoutExtension);
// get gateway ID
var gatewayId = await _powerBIService.GetGatewayIdFromWorkspaceAndDataset(newWorkspaceId, datasetId);
if (gatewayId != null)
{
//update credentials
await _powerBIService.UpdateGatewayDatasourcesCredentials(gatewayId, persona.SQLUser, persona.SQLPassword);
Console.WriteLine("Updated connection details for gateway {0}", reportNameWithoutExtension);
}
These are the individual methods:
public async Task UpdateConnectionAsync(string workspaceId, string datasetId, string sqlUser, string sqlPwd)
{
var bearerToken = await GetBearerTokenAsync();
var tokenCredentials = new TokenCredentials(bearerToken, "Bearer");
using (var client = new PowerBIClient(new Uri(_pbiApiUrl), tokenCredentials))
{
var dataSourcesResponse = await client.Datasets.GetDatasourcesInGroupAsync(workspaceId, datasetId);
var sqlDataSources = dataSourcesResponse.Value?.Where(s => s.DatasourceType == "Sql")
.Where(s => !s.ConnectionString.Contains(_reportsSQLServer) || !s.ConnectionString.Contains(_reportsSQLServer));
foreach (var sqlDataSource in sqlDataSources)
{
var updateDataSourceConnectionRequest = new UpdateDatasourceConnectionRequest();
updateDataSourceConnectionRequest.ConnectionDetails = new DatasourceConnectionDetails(_reportsSQLServer, _reportsSQLDatabase);
//updateDataSourceConnectionRequest.DatasourceSelector = new Datasource(datasourceId: sqlDataSource.DatasourceId);
var datasourcesRequest = new UpdateDatasourcesRequest();
datasourcesRequest.UpdateDetails = new List<UpdateDatasourceConnectionRequest>() { updateDataSourceConnectionRequest };
var result = await client.Datasets.UpdateDatasourcesInGroupAsync(workspaceId, datasetId, datasourcesRequest);
//await client.Gateways.UpdateDatasourceAsync()
}
}
}
public async Task UpdateGatewayDatasourcesCredentials(string gatewayId, string sqlUser, string sqlPassword)
{
var bearerToken = await GetBearerTokenAsync();
var tokenCredentials = new TokenCredentials(bearerToken, "Bearer");
using (var client = new PowerBIClient(new Uri(_pbiApiUrl), tokenCredentials))
{
var datasourcesResult = await client.Gateways.GetDatasourcesAsync(gatewayId);
var sqlGatewayDatasources = datasourcesResult.Value?
.Where(s => s.DatasourceType == "Sql")
.Where(s => s.ConnectionDetails.Contains(_reportsSQLServer) && s.ConnectionDetails.Contains(_reportsSQLDatabase));
foreach (var gatewayDatasource in sqlGatewayDatasources)
{
var updateDataSourceRequest = new UpdateDatasourceRequest();
updateDataSourceRequest.CredentialDetails = new CredentialDetails();
updateDataSourceRequest.CredentialDetails.CredentialType = "Basic";
updateDataSourceRequest.CredentialDetails.Credentials = "{\"credentialData\":[{\"name\":\"username\", \"value\":\"" + sqlUser + "\"},{\"name\":\"password\", \"value\":\"" + sqlPassword + "\"}]}";
updateDataSourceRequest.CredentialDetails.EncryptedConnection = "Encrypted";
updateDataSourceRequest.CredentialDetails.EncryptionAlgorithm = "None";
updateDataSourceRequest.CredentialDetails.PrivacyLevel = "None";
var result = await client.Gateways.UpdateDatasourceAsync(gatewayId, gatewayDatasource.Id, updateDataSourceRequest);
}
}
}
When I attempt to view the report there is no data being fetched from the database.
Interestingly I can login manually using the PowerBI portal using the same credentials. After the manual login the report is fetching data.
If after the manual login I delete the workspace and then recreate and re-import the report programatically then the report will show data. This makes me think there is some caching involved after the manual logic which is persisted outside of the workspace.
Any suggestions on what is missing here?

Testing filters with IDependencyScope in Web API

I have WebApi simple NUnit Test
[Test]
public async Task Test()
{
var attribute = new TestAuthenticationAttribute {ApiVersions = new[] {"v1"}};
System.Web.Http.Controllers.HttpActionContext context = CreateExecutingContext();
var executedContext = new HttpAuthenticationContext(context, null);
const string reasonPhrase = "ReasonPhrase";
const string messagePhrase = "MessagePhrase";
executedContext.ErrorResult = new AuthenticationFailureResult(reasonPhrase, messagePhrase, executedContext.Request);
await attribute.AuthenticateAsync(executedContext, CancellationToken.None);
var errorResult = await executedContext.ErrorResult.ExecuteAsync(new CancellationToken());
Assert.AreEqual(HttpStatusCode.Unauthorized, errorResult.StatusCode);
}
private System.Web.Http.Controllers.HttpActionContext CreateExecutingContext()
{
return new System.Web.Http.Controllers.HttpActionContext { ControllerContext = new HttpControllerContext {Request = new HttpRequestMessage()
{
RequestUri = new Uri("http://TestApi/api/v1/Test")
}}};
}
and in TestAuthenticationAttribute I have
if (context.Request.GetDependencyScope().GetService(typeof(IExternalService)) is IExternalService externalService)
Do some actions;
How to set/resolve IExternalService dependency in test? Do I need e.g. UnityContainer or I can do it without container?
I added HttpConfiguration to my HttpActionContext and now Context.Request.GetDependencyScope() doesn't throw System.NullReferenceException. Of cource ontext.Request.GetDependencyScope().GetService(typeof(IExternalService)) is null, but now It's ok for my tests.
private System.Web.Http.Controllers.HttpActionContext CreateExecutingContext()
{
var config = new HttpConfiguration();
var httpActionContext = new System.Web.Http.Controllers.HttpActionContext
{
ControllerContext = new HttpControllerContext
{
Request = new HttpRequestMessage()
{
RequestUri = new Uri("http://TestApi/api/v1/Test"),
},
Configuration = config
}
};
httpActionContext.ControllerContext.Request.Properties[HttpPropertyKeys.HttpConfigurationKey] = config;
return httpActionContext;
}
If I want to resolve dependency, I will can add DependencyResolver to my config or Mocking framework

Retrieving cookies from httprequest in Xamarin.forms

help me, i couldn't get the cookies from an httprequest, i tried the plugins.settings, i tried the pcl share too, am in this problem for a month
public async Task<bool> PostAsync(AuthUser user)
{
var CookieContainer = new CookieContainer();
var handler = new HttpClientHandler() { CookieContainer =
CookieContainer };
var _client = new HttpClient(handler);
IEnumerable<string> cookieStrings = null;
//var httpClient = new HttpClient();
_client.DefaultRequestHeaders.Accept.Add(new
MediaTypeWithQualityHeaderValue("application/json"));
var json = JsonConvert.SerializeObject(user);
HttpContent httpContent = new StringContent(json);
httpContent.Headers.ContentType = new MediaTypeHeaderValue("application/json");
try
{
string url = WebServiceUrl + "j_spring_security_check?j_username=" + user.j_username +"&j_password=" + user.j_password + "&ajax=true";
HttpResponseMessage result = await _client.PostAsync(url, httpContent);
IEnumerable<string> cookies;
if (result.Headers.TryGetValues("set-cookie", out cookies))
{
foreach (var c in cookies)
{
await App.Current.MainPage.DisplayAlert("Cookie", c , "OK");
}
}
if (result.IsSuccessStatusCode)
{
using (var responsecontent = result.Content)
{
string resultString = responsecontent.ReadAsStringAsync().Result;
var response = JsonConvert.DeserializeObject<AuthUser>(resultString);
if (response.error != null)
{
await App.Current.MainPage.DisplayAlert("Error", response.result.error, "OK");
return false;
}
else if (response.result.success.Equals("1"))
{
App.Current.MainPage = new NavigationPage(new TimelineMenuPage(response.result.user_id.ToString(), response.result.token));
return true;
}
}
}
return result.IsSuccessStatusCode;
}
catch (Exception e)
{
await App.Current.MainPage.DisplayAlert("Alert", e.ToString(), "OK");
throw;
}
}
when debugging it skips this part :
if (result.Headers.TryGetValues("set-cookie", out cookies))
{
foreach (var c in cookies)
{
await App.Current.MainPage.DisplayAlert("Cookie", c , "OK");
}
}
**and then i get in CookieContainer count=0 **
Since you are already using a CookieContainer, and you will know the Uri you are getting them from, why don't you just get the Cookies directly from the Container, instead of a set-cookie command, that you will then have to parse.
cookieContainer.GetCookies(new Uri("mydomain.com"));
After your HttpRequest, it will automatically put them into the CookieContainer.
