Power BI Embedded with Roles, allowing Row Level Security

I have implemented the Microsoft Example for Embed for your customers from Github, which works perfectly. Link
I am now extending it which there are articles showing using both V1 and V2 of the API, both result in the same error:
Operation returned an invalid status code 'BadRequest'
at
Microsoft.PowerBI.Api.ReportsOperations.GenerateTokenInGroupWithHttpMessagesAsync(Guid
groupId, Guid reportId, GenerateTokenRequest requestParameters,
Dictionary`2 customHeaders, CancellationToken cancellationToken)
[HttpGet]
public async Task<string> GetEmbedInfo()
{
try
{
// Validate whether all the required configurations are provided in appsettings.json
string configValidationResult = ConfigValidatorService.ValidateConfig(azureAd, powerBI);
if (configValidationResult != null)
{
HttpContext.Response.StatusCode = 400;
return configValidationResult;
}
EmbedParams embedParams = await pbiEmbedService.GetEmbedParams(new Guid(powerBI.Value.WorkspaceId), new Guid(powerBI.Value.ReportId));
//EmbedParams embedParams = await pbiEmbedService.GetEmbedToken4(new Guid(powerBI.Value.WorkspaceId), new Guid(powerBI.Value.ReportId));
return JsonSerializer.Serialize<EmbedParams>(embedParams);
}
catch (Exception ex)
{
HttpContext.Response.StatusCode = 500;
return ex.Message + "\n\n" + ex.StackTrace;
}
}
The above code is getting called and per the demo.
public async Task<EmbedParams> GetEmbedParams(Guid workspaceId, Guid reportId, [Optional] Guid additionalDatasetId)
{
PowerBIClient pbiClient = this.GetPowerBIClient();
// Get report info
var pbiReport = await pbiClient.Reports.GetReportInGroupAsync(workspaceId, reportId);
//var generateTokenRequestParameters = new GenerateTokenRequest("View", null, identities: new List<EffectiveIdentity> { new EffectiveIdentity(username: "**************", roles: new List<string> { "****", "****" }, datasets: new List<string> { "datasetId" }) });
//var tokenResponse = pbiClient.Reports.GenerateTokenInGroupAsync("groupId", "reportId", generateTokenRequestParameters);
// Create list of datasets
var datasetIds = new List<Guid>();
// Add dataset associated to the report
datasetIds.Add(Guid.Parse(pbiReport.DatasetId));
// Append additional dataset to the list to achieve dynamic binding later
if (additionalDatasetId != Guid.Empty)
{
datasetIds.Add(additionalDatasetId);
}
// Add report data for embedding
var embedReports = new List<EmbedReport>() {
new EmbedReport
{
ReportId = pbiReport.Id, ReportName = pbiReport.Name, EmbedUrl = pbiReport.EmbedUrl
}
};
// Get Embed token multiple resources
var embedToken = await GetEmbedToken4(workspaceId, reportId);
// Capture embed params
var embedParams = new EmbedParams
{
EmbedReport = embedReports,
Type = "Report",
EmbedToken = embedToken
};
return embedParams;
}
The above code is per the demo apart from one line, which is calling the next method:
var embedToken = await GetEmbedToken4(workspaceId, reportId);
public EmbedToken GetEmbedToken(Guid reportId, IList<Guid> datasetIds, [Optional] Guid targetWorkspaceId)
{
PowerBIClient pbiClient = this.GetPowerBIClient();
// Create a request for getting Embed token
// This method works only with new Power BI V2 workspace experience
var tokenRequest = new GenerateTokenRequestV2(
reports: new List<GenerateTokenRequestV2Report>() { new GenerateTokenRequestV2Report(reportId) },
datasets: datasetIds.Select(datasetId => new GenerateTokenRequestV2Dataset(datasetId.ToString())).ToList(),
targetWorkspaces: targetWorkspaceId != Guid.Empty ? new List<GenerateTokenRequestV2TargetWorkspace>() { new GenerateTokenRequestV2TargetWorkspace(targetWorkspaceId) } : null
);
// Generate Embed token
var embedToken = pbiClient.EmbedToken.GenerateToken(tokenRequest);
return embedToken;
}
The above code is per the example with no roles being passed in or EffectiveIdentity. This works.
public async Task<EmbedToken> GetEmbedToken4(Guid workspaceId, Guid reportId, string accessLevel = "view")
{
PowerBIClient pbiClient = this.GetPowerBIClient();
var pbiReport = pbiClient.Reports.GetReportInGroup(workspaceId, reportId);
string dataSet = pbiReport.DatasetId.ToString();
// Generate token request for RDL Report
var generateTokenRequestParameters = new GenerateTokenRequest(
accessLevel: accessLevel,
datasetId: dataSet,
identities: new List<EffectiveIdentity> { new EffectiveIdentity(username: "******", roles: new List<string> { "********" }) }
);
// Generate Embed token
var embedToken = pbiClient.Reports.GenerateTokenInGroup(workspaceId, reportId, generateTokenRequestParameters);
return embedToken;
}
This is the method to return the token with the roles and effective Identity. This results in the error, but no message or helpful feedback.

OK, after much research overnight the Bad Request response does hide an English message which is not show in the browser. The debugger doesn't have the symbols for the part that causes the error, but I found it by using Fiddler proxy when the actual API responded to the request. In my case, if you send an ID to enable RLS, but the version of the report on the server doesn't have it, this doesn't ignore it, it refuses to give a token to anything. From reading many posts, the Bad Request is just a poor error message when the actual response from the API itself (not the package or the example code that the sample uses with it presents). Hope this helps someone in the future.

Xero invoice send email using standard .NET library

Here I have created my project on the standard .NET library to GET/POST invoices. But as I want to email the invoice to which it's being created on that name. Here is my sample code below to create invoice.
public async Task<ActionResult> Create(string Name, string LineDescription, string LineQuantity, string LineUnitAmount, string LineAccountCode)
{
var xeroToken = TokenUtilities.GetStoredToken();
var utcTimeNow = DateTime.UtcNow;
var serviceProvider = new ServiceCollection().AddHttpClient().BuildServiceProvider();
var httpClientFactory = serviceProvider.GetService<IHttpClientFactory>();
XeroConfiguration XeroConfig = new XeroConfiguration
{
ClientId = ConfigurationManager.AppSettings["XeroClientId"],
ClientSecret = ConfigurationManager.AppSettings["XeroClientSecret"],
CallbackUri = new Uri(ConfigurationManager.AppSettings["XeroCallbackUri"]),
Scope = ConfigurationManager.AppSettings["XeroScope"],
State = ConfigurationManager.AppSettings["XeroState"]
};
if (utcTimeNow > xeroToken.ExpiresAtUtc)
{
var client = new XeroClient(XeroConfig, httpClientFactory);
xeroToken = (XeroOAuth2Token)await client.RefreshAccessTokenAsync(xeroToken);
TokenUtilities.StoreToken(xeroToken);
}
string accessToken = xeroToken.AccessToken;
string xeroTenantId = xeroToken.Tenants[0].TenantId.ToString();
//string xeroTenantId = xeroToken.Tenants[1].TenantId.ToString();
var contact = new Contact();
contact.Name = Name;
var line = new LineItem()
{
Description = LineDescription,
Quantity = decimal.Parse(LineQuantity),
UnitAmount = decimal.Parse(LineUnitAmount),
AccountCode = LineAccountCode
};
var lines = new List<LineItem>() { line };
//var lines = new List<LineItem>();
//for (int j = 0;j < 5;j++)
//{
// lines.Add(line);
//}
var invoice = new Invoice()
{
Type = Invoice.TypeEnum.ACCREC,
Contact = contact,
Date = DateTime.Today,
DueDate = DateTime.Today.AddDays(30),
LineItems = lines
};
var invoiceList = new List<Invoice>();
invoiceList.Add(invoice);
var invoices = new Invoices();
invoices._Invoices = invoiceList;
var AccountingApi = new AccountingApi();
var response = await AccountingApi.CreateInvoicesAsync(accessToken, xeroTenantId, invoices);
RequestEmpty _request = new RequestEmpty();
//trying this method to send email to specified invoice....
//var test = await AccountingApi.EmailInvoiceAsync(accessToken, xeroTenantId, Guid.NewGuid(), null);
var updatedUTC = response._Invoices[0].UpdatedDateUTC;
return RedirectToAction("Index", "InvoiceSync");
}
Now as I learned that Xero allows sending email to that specified invoice, here is a link which I learned.
https://developer.xero.com/documentation/api/invoices#email
But as try to find method in the .NET standard library for Xero I stumble upon this method.
var test = await AccountingApi.EmailInvoiceAsync(accessToken, xeroTenantId, Guid.NewGuid(), null);
How can I use this method to send email to a specified invoice ..?
It throws me an error regarding Cannot assign void to an implicitly-typed variable.
There is another method also in this library.
var test2 = await AccountingApi.EmailInvoiceAsyncWithHttpInfo(accessToken, xeroTenantId, Guid.NewGuid(), null);
As Guid.NewGuid() i have used is for only testing will add created GUID when I understand how these two methods operate.
Update 1:
Here is the method second method i used.
await AccountingApi.EmailInvoiceAsyncWithHttpInfo(accessToken, xeroTenantId, Guid.NewGuid(), null)
Update 2:
Here is the code i used.
public async Task EmailInvoiceTest(string accessToken,string xeroTenantId,Guid invoiceID, RequestEmpty requestEmpty)
{
var AccountingApi = new AccountingApi();
await AccountingApi.EmailInvoiceAsync(accessToken, xeroTenantId, invoiceID, requestEmpty).ConfigureAwait(false);
}

The return type of method EmailInvoiceAsync seems to be Task with return type void. If you await the task, there is no return type which could be assigned to a variable. Remove the variable assignment and pass a valid argument for parameter of type RequestEmpty to solve the problem.
RequestEmpty requestEmpty = new RequestEmpty();
await AccountingApi.EmailInvoiceAsync(accessToken, xeroTenantId, Guid.NewGuid(), requestEmpty);
For an example test see here
IMPORTANT: According to the documentation (see section Emailing an invoice) the invoice must be of Type ACCREC and must have a valid status for sending (SUMBITTED, AUTHORISED or PAID).

Making DialogFlow v2 DetectIntent Calls w/ C# (including input context)

So I finally figured out a way to successfully make detect intent calls and provide an input context. My question is whether or not this is the CORRECT (or best) way to do it:
(And yes, I know you can just call DetectIntent(agent, session, query) but I have to provide a input context(s) depending on the request)
var query = new QueryInput
{
Text = new TextInput
{
Text = model.Content,
LanguageCode = string.IsNullOrEmpty(model.Language) ? "en-us" : model.Language,
}
};
var commonContext = new global::Google.Cloud.Dialogflow.V2.Context
{
ContextName = new ContextName(agent, model.sessionId, "my-input-context-data"),
LifespanCount = 3,
Parameters = new Struct
{
Fields = {
{ "Source", Value.ForString(model.Source) },
{ "UserId" , Value.ForString(model.UserId.ToString())},
{ "Name" , Value.ForString(model.FirstName)}
}
}
};
var request = new DetectIntentRequest
{
SessionAsSessionName = new SessionName(agent, model.sessionId),
QueryParams = new QueryParameters
{
GeoLocation = new LatLng {Latitude = model.Latitude, Longitude = model.Longitude},
TimeZone = model.TimeZone ?? "MST"
},
QueryInput = query
};
request.QueryParams.Contexts.Add(commonContext);
// ------------
var creds = GetGoogleCredentials("myCredentials.json");
var channel = new Grpc.Core.Channel(SessionsClient.DefaultEndpoint.Host, creds.ToChannelCredentials());
var client = SessionsClient.Create(channel);
var response = client.DetectIntent(request);
channel.ShutdownAsync();
return response;
Note: I included the explicit ShutDownAsync (it's not in an async call) because I was getting some file locking issues when attempting to re-deploy the WebAPI project (and only after having executed this code).
Thanks
Chris
Updated 4/25: The most basic way I use this is to integrate the user's name into intent responses:
It can also be read from within the webhook/inline fulfillment index.js:
const name = request.body.queryResult && request.body.queryResult.outputContexts && request.body.queryResult.outputContexts[0].parameters.Name

How to store & retrieve Bot Data in Azure Table storage with directLine channel?

I'm using Microsoft Bot Framework with directLine channel. My Bot is a part of company's customer portal from where I fetch some user information and store it in BotState using stateClient as shown below
public ActionResult Index()
{
var userId = ClaimsPrincipal.Current.FindFirst(ClaimTypes.NameIdentifier).Value;
GetTokenViaBootStrap().Wait();
var botCred = new MicrosoftAppCredentials(
ConfigurationManager.AppSettings["MicrosoftAppId"],
ConfigurationManager.AppSettings["MicrosoftAppPassword"]);
var stateClient = new StateClient(botCred);
BotState botState = new BotState(stateClient);
BotData botData = new BotData(eTag: "*");
botData.SetProperty<string>("UserName", result.UserInfo.GivenName + " " + result.UserInfo.FamilyName);
botData.SetProperty<string>("Email", result.UserInfo.DisplayableId);
botData.SetProperty<string>("GraphAccessToken", UserAccessToken);
botData.SetProperty<string>("TokenExpiryTime", result.ExpiresOn.ToString());
stateClient.BotState.SetUserDataAsync("directline", userId, botData).Wait();
var UserData = new UserInformationModel
{
UserId = userId,
UserName = result.UserInfo.GivenName + " " + result.UserInfo.FamilyName
};
return View(UserData);
}
As its a directLine channel, I'm connecting my bot using secret in javascript as shown below:
BotChat.App({
bot: { id: 'my_bot_id', name: 'my_bot_id' },
resize: 'detect',
sendTyping: true, // defaults to false. set to true to send 'typing' activities to bot (and other users) when user is typing
user: { id: UserData.UserId},
directLine: {
secret: "my_bot_secret"
}
}, document.getElementById('my_bot_id'));
I'm accessing user information data in Node js Bot captured in MVC site as shown below:
function sessionUserCapture(session) {
switch (session.message.address.channelId) {
case 'skypeforbusiness':
// some code
break;
case 'directline':
userName= session.userData.UserName;
userEmail= session.userData.Email;
//some code
break;
case 'slack':
// some code
}
}
I referred Microsoft's Save state data from Manage state data for above code and then I used userData available in the session to access this data in my Node.JS Bot.
As the StateClient is Deprecated, I referred this to replace stateclient with Azure Table storage. However, I'm not able to understand how can I store the above data in the Table Storage.
Can anyone suggest any article which I can refer to solve this issue?
My Bot is in NodeJs and the I'm using directLine channel in a C# MVC application.

One option is to use the Microsoft Azure Storage Client Library for .NET, as explained in the answer here: How to retrieve Saved Conversation Data in Azure (Tablelogger) Just make sure to follow the exact same PartitionKey strategy as is followed by the TableBotDataStore class, and serialize the data field correctly.

Edit:
I tested this out, and it does in fact work as expected.
public class WebChatController : Controller
{
public ActionResult Index()
{
var connectionString = ConfigurationManager.ConnectionStrings["StorageConnectionString"].ConnectionString;
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(connectionString);
CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
CloudTable table = tableClient.GetTableReference("BotStore");
string userId = Guid.NewGuid().ToString();
TableQuery<BotDataRow> query = new TableQuery<BotDataRow>().Where(TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, userId));
var dataRow = table.ExecuteQuery(query).FirstOrDefault();
if(dataRow != null)
{
dataRow.Data = Newtonsoft.Json.JsonConvert.SerializeObject(new
{
UserName = "This user's name",
Email = "whatever#email.com",
GraphAccessToken = "token",
TokenExpiryTime = DateTime.Now.AddHours(1)
});
dataRow.Timestamp = DateTimeOffset.UtcNow;
table.Execute(TableOperation.Replace(dataRow));
}
else
{
var row = new BotDataRow(userId, "userData");
row.Data = Newtonsoft.Json.JsonConvert.SerializeObject(new
{
UserName = "This user's name",
Email = "whatever#email.com",
GraphAccessToken = "token",
TokenExpiryTime = DateTime.Now.AddHours(1)
});
row.Timestamp = DateTimeOffset.UtcNow;
table.Execute(TableOperation.Insert(row));
}
var vm = new WebChatModel();
vm.UserId = userId;
return View(vm);
}
public class BotDataRow : TableEntity
{
public BotDataRow(string partitionKey, string rowKey)
{
this.PartitionKey = partitionKey;
this.RowKey = rowKey;
}
public BotDataRow() { }
public bool IsCompressed { get; set; }
public string Data { get; set; }
}
}
In the node bot:
'use strict';
const builder = require('botbuilder');
const restify = require('restify');
var azure = require('botbuilder-azure');
var tableName = 'BotStore';
var azureTableClient = new azure.AzureTableClient(tableName,'accountname','accountkey');
var tableStorage = new azure.AzureBotStorage({ gzipData: false }, azureTableClient);
const connector = new builder.ChatConnector({
appId: process.env.MicrosoftAppId,
appPassword: process.env.MicrosoftAppPassword
});
const server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3979, () => {
console.log(`${server.name} listening to ${server.url}`);
});
server.post('/api/messages', connector.listen());
var bot = new builder.UniversalBot(connector)
.set('storage', tableStorage);;
bot.dialog('/',
[
function (session){
var data = session.userData;
}
]);

The code you are using is using the deprecated default state and will not work. In order to accomplish what you would like it depends on where you are in your code. The deciding factor is if you have access to the context object or not.
For example if you are in the MessagesController you will not have access to the context object and your code might look like this:
public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
{
if (activity.Type == ActivityTypes.Message)
{
var message = activity as IMessageActivity;
using (var scope = DialogModule.BeginLifetimeScope(Conversation.Container, message))
{
var botDataStore = scope.Resolve<IBotDataStore<BotData>>();
var key = Address.FromActivity(message);
var userData = await botDataStore.LoadAsync(key, BotStoreType.BotUserData, CancellationToken.None);
userData.SetProperty("key 1", "value1");
userData.SetProperty("key 2", "value2");
await botDataStore.SaveAsync(key, BotStoreType.BotUserData, userData, CancellationToken.None);
await botDataStore.FlushAsync(key, CancellationToken.None);
}
await Conversation.SendAsync(activity, () => new Dialogs.RootDialog());
}
}
then to get the data:
userData.GetProperty<string>("key 1");
The other situation would be if you did have access to the context object like in a Dialog for example, your code might look like this:
context.UserData.SetValue("key 1", "value1");
context.UserData.SetValue("key 2", "value2");
then to get the data:
context.UserData.GetValue<string>("key 1");

Have you configured your bot to connect to Azure Table Storage in Global.asax.cs, instead of the deprecated default state?
I have written a blog post with full details on how to move your bot's state to Azure Table Storage which you should review
here
protected void Application_Start()
{
Conversation.UpdateContainer(
builder =>
{
builder.RegisterModule(new AzureModule(Assembly.GetExecutingAssembly()));
// Using Azure Table for storage
var store = new TableBotDataStore(ConfigurationManager.ConnectionStrings["StorageConnectionString"].ConnectionString);
builder.Register(c => store)
.Keyed<IBotDataStore<BotData>>(AzureModule.Key_DataStore)
.AsSelf()
.SingleInstance();
});
GlobalConfiguration.Configure(WebApiConfig.Register);
}

Xamarin: Using HttpClient POST in combination with a dynamic Class

I have some services that require rather complex objects. Every service uses almost the same base object but it needs to be extended for each service.
A simple example:
The Standard Object would be something like:
ContextObject {
params {
Device {
Name: "MyMobileDevice",
ID: 123455691919238
}
}
}
and for my service I need to add some properties under params,
something like:
ContextObject {
params {
Device {
Name: "MyMobileDevice",
ID: 123455691919238
},
requested_employee_id: 112929
}
}
I tried to get this by using JObject and got it working so far but now I cant find a proper example on how to send this object to my server using HttpClient.
Edit:
Here is my full JObject which all Requests need:
public static JObject DefaultContext (string ServiceMethod) {
var Context = new JObject();
Context["version"] = "1.1";
Context["method"] = ServiceMethod;
Context["params"] = JObject.FromObject( new {
Context = JObject.FromObject( new {
User = App.UserSettings.USERNAME,
Password = App.UserSettings.PASSWORD,
SerialNumber = "1234567890", // TODO: use generated id
Locale = "de-DE",
Timestamp = DateTime.Now.ToString("yyyy-MM-ddTHH\\:mm\\:ss.fffzzz"),
Device = JObject.FromObject( new {
DeviceType = "phone",
ProductType = "D6603", // TODO: Get from Device-Info
screen = JObject.FromObject( new {
Density = "xxhdpi", // TODO: Get from Device-Info
resolution = JObject.FromObject( new {
Height = "1920", // TODO: Get from Device-Info
Width = "1080" // TODO: Get from Device-Info
})
}),
version = JObject.FromObject( new {
AppVersion = "myAppVersion", // TODO: Get App-Information LayoutVersion = "1.0"
} )
})
})
});
return mobileContext;
}
For my Requests I need to add parameters under the "params"-Node. Which works with:
mobileContext["params"]["mynewparameter"] = "FOO";
Now I wanted to send this JObject via System.Net.Http-Client to my server with something like this:
var client = new HttpClient ();
client.BaseAddress = new Uri (App.UserSettings.HOST + ":" + App.UserSettings.PORT + App.UserSettings.TYPE);
client.Timeout = 3000;
var context = MyContext.DefaultContext (ServiceMethods.CUSTOMER_LIST_METHOD);
context ["params"] ["myrequestparam"] = "FOO";
var jsonString = JsonConvert.SerializeObject (context);
var responseData = await client.Get???????
Is my general approach correct? How would you do it? Is there a sample on how to handle such dynamic stuff?
I couldn't find a example on how to use httpclient correctly with the Newtonsoft.JSON-Library how far am I from actually working code?
