AmazonAWSHealthClient.DescribeEventsRequest: No such host is known - c#

I want to make a request for the health events on my AWS account. I use this code to do the request:
using (var client = new AmazonAWSHealthClient("accesskey", "privatekey", RegionEndpoint.EUCentral1))
{
var request = new DescribeEventsRequest();
var response = client.DescribeEventsAsync(request).Result;
}
But the response is "No such host is known". What do I need to change? Do I need to alter some settings on my AWS account?

I had to switch out the EUCentral1 in the clients constructor for USEast1 and it worked (I was then missing some permissions, but that I can fix). Not providing a region for the client also didn't help, I specifically had to provide the USEast1 region. Apparently that region is the one that AWS treats as "Global", as you see "Global" selected as a region, when you are in the Personal Health Dashboard.

How do I get accounts from Azure AD?

I have a nice Azure Active Directory set up with a dozen users. (All me!) So I have a Tenant ID, client ID and Client Secret.
I am also working on a simple console application that will function as a public client for this directory. This client also holds a list of usernames and passwords as this is just meant as a simple experiment. Not secure, I know. But I first need to understand how it works...
I do this:
IConfidentialClientApplication client = ConfidentialClientApplicationBuilder
.CreateWithApplicationOptions(options).Build();
And this creates my client app. Works fine.
I also get a token using "https://graph.microsoft.com/.default" and can use this to get all users as JSON:
string result = await GetHttpContentWithToken("https://graph.microsoft.com/v1.0/users",
token.AccessToken);
Although I might want it to be more user-friendly, JSON is fine for now.
How can I check if user is an authorized user?
And no, I don't want complex solutions that require various nuget packages. Just a plain and simple step-by-step explanation. I could probably Google this but I ended up with thousands of results and none were helpful... This should be easy, right?
[EDIT] I first wanted to get a list of users nut that failed because of a typo... (There's a dot before 'default'...)
It took some fooling around but it's not too difficult after all. There are a lot of libraries around Azure but it is all basically just a bunch of HTTP requests and responses. Even in a console application...
I started with making a PublicClientApplicationBuilder first:
var options = new PublicClientApplicationOptions()
{
ClientId = <**clientid**>,
TenantId = <**tenantid**>,
AzureCloudInstance = AzureCloudInstance.AzurePublic,
};
var client = PublicClientApplicationBuilder.CreateWithApplicationOptions(options).Build();
I can also create a ConfidentialClientApplication instead, but this allows me to log in interactively, if need be.
Next, set up the scopes:
var scopes = new List<string>() { "https://graph.microsoft.com/.default" };
As I wanted to log in using username and password, I have to use this:
var token = await client.AcquireTokenInteractive(scopes).ExecuteAsync();
But if I want to log in using code, I can also use this:
var password = new SecureString();
foreach (var c in <**password**>) { password.AppendChar(c); }
var token = await client.AcquireTokenByUsernamePassword(scopes, <**account**>, password).ExecuteAsync();
At this point, I'm authorized as the specified user. So, now all I need is to get whatever data I like, in JSON strings...
public static async Task<string> ExecCmd(string name, string url, string token)
{
HttpClient httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("bearer", token);
string result = await GetHttpContentWithToken(url, token);
JObject json = JsonConvert.DeserializeObject(result) as JObject;
File.WriteAllText(name, json.ToString());
return result;
}
As I just want to read the data as text files, I just execute the action in using a specific and write it as formatted JSON to the file . So, using this simple method I can now use this:
await ExecCmd("Profile.txt", "https://graph.microsoft.com/v1.0/me/", token.AccessToken);
await ExecCmd("Groups.txt", "https://graph.microsoft.com/v1.0/groups", token.AccessToken);
await ExecCmd("Users.txt", "https://graph.microsoft.com/v1.0/users", token.AccessToken);
These will provide me with (1) the profile of the current user, (2) the AD groups and (3) the AD users. And probably a bit more...
I can use this ExecCmd to retrieve a lot more data, if I want to. But there's something else to keep in mind! For it all to work, you also need to configure the Azure application and make sure all access rights are assigned and approved!
So, in Azure AD you have to add an "App registration" and fiddle around with the settings... (The Azure experts are horribly shocked now, but when you want to learn, you'd just have to try and fail until you succeed...)
Also set "Default client type" to "public client" for the registered app.
In Azure, with the registered app, you also need to set the proper API permissions! Otherwise, you won't have access. And as I want access to Active Directory, I need to add permissions to "Azure Active Directory Graph". I can do this inside Azure or by using the scope when I call AcquireTokenInteractive(). For example, by using "https://graph.windows.net/Directory.Read.All" instead of "https://graph.windows.net/.default".
Once you've accessed a token interactively, you can also get more tokens using client.AcquireTokenSilent(). It gets a bit tricky from here, especially if you want to access a lot of different items. Fortunately, Active Directory is mostly the directory itself, groups, users and members.
Personally, I prefer to grant access from the Azure website but this is quite interesting.
Anyways, I wanted to authenticate users with Azure and now I know how to do this. It still leaves a lot more questions but this all basically answers my question...
I'll use this as answer, as others might find it useful...

Operation returned an invalid status code 'Forbidden`. Botframework v4

So i created a bot in azure and downloaded it. The free 1000 calls from LUIS reached its limit. I created a subscription in azure portal (I did do the docker container something). Followed this guide until step 6. When i click the endpoint url and query directly in the browser it is working fine.
I added it to the bot via Bot Emulator by clicking + sign in services and adding the bot model there. But when i run bot i get the title error. I noticed in the .bot file the authoring key and subscription key added by the bot emulator is the same.
So i changed the subscription key to the one of the keys generated by azure and still the same error. I have tried reseting the authoring key still same and deleting my luis.ai account and created a new one. (still same email because that is the one logged in azure portal.) and still the same.
Here are some pictures for reference and the error.
I also tried testing it in luis.ai and got this result.
but when i check it is set to the new resource.
Here is a pic of the bot file after adding luis via Bot emulator. It has same authoring key and subscription key (still forbidden)
so i changed it now with subscription key (still forbidden).
Here it is working properly when tested directly in the URL.
For reference:
azure portal
luis.ai
and the error
How i add luis in the bot.
Here is the code for the bot service.
using System;
using System.Collections.Generic;
using Microsoft.Bot.Builder.AI.Luis;
using Microsoft.Bot.Configuration;
namespace Microsoft.BotBuilderSamples
{
public class BotServices
{
public BotServices(BotConfiguration botConfiguration)
{
foreach (var service in botConfiguration.Services)
{
switch (service.Type)
{
case ServiceTypes.Luis:
{
var luis = (LuisService)service;
if (luis == null)
{
throw new InvalidOperationException("The LUIS service is not configured correctly in your '.bot' file.");
}
var endpoint = (luis.Region?.StartsWith("https://") ?? false) ? luis.Region : luis.GetEndpoint();
var app = new LuisApplication(luis.AppId, luis.AuthoringKey, endpoint);
var recognizer = new LuisRecognizer(app);
this.LuisServices.Add(luis.Name, recognizer);
break;
}
}
}
}
public Dictionary<string, LuisRecognizer> LuisServices { get; } = new Dictionary<string, LuisRecognizer>();
}
}
I am trying to solve this for 4 days already. Thanks!
Thank you for all of the images. That is a HUGE help! Here's the problem:
By default, your code looks for the AuthoringKey in this section (second line):
var endpoint = (luis.Region?.StartsWith("https://") ?? false) ? luis.Region : luis.GetEndpoint();
var app = new LuisApplication(luis.AppId, luis.AuthoringKey, endpoint);
var recognizer = new LuisRecognizer(app);
this.LuisServices.Add(luis.Name, recognizer);
Since your .bot file still has the authoringKey set to the one that starts with ad9c..., which has hit its limit, your bot keeps running into the 403 error.
So, in your .bot file, replace that authoringKey with one of your endpointKeys (they start with 12ccc... or b575...).
I understand your confusion with this, especially since this requires you putting an endpointKey in your authoringKey property. I know there's some changes on the horizon to how LUIS bots will use keys, but those are probably a month or more out.
Alternatively, you can change:
var app = new LuisApplication(luis.AppId, luis.AuthoringKey, endpoint);
to:
var app = new LuisApplication(luis.AppId, luis.SubscriptionKey, endpoint);
Note: If you make either of these changes, LUIS can only query (which is usually fine), since Authoring Keys do everything else (see reference, below)

These are not so much for you as much as others that might come across this.

Cannot create a new Topic in ServiceBus with CreateTopicAsync

I'm trying to create a new Topic (and then a subscription) with the method CreateTopicAsync of the library Microsoft.Azure.ServiceBus.Management.
The connection string is correct and I can send and receive messages if I create the topic trough the Azure portal.
What am I doing wrong? Any help is appreciated.
var managementClient = new ManagementClient(ServiceBusConnectionString);
bool topicExists = await managementClient.TopicExistsAsync(TopicName).ConfigureAwait(false);
if (!topicExists) {
TopicDescription td = new TopicDescription(TopicName);
td.MaxSizeInMB = 1024;
td.DefaultMessageTimeToLive = new TimeSpan(2, 0, 0, 0);
await managementClient.CreateTopicAsync(td).ConfigureAwait(false);
}
Although the Service Bus ConnectionString might be correct, for your application to be able to create a Topic it needs to have the Manage right (claim).
Taken from Service Bus access control with Shared Access Signatures:
For each authorization policy rule, you decide on three pieces of information: name, scope, and rights. The name is just that; a unique name within that scope. The scope is easy enough: it's the URI of the resource in question. For a Service Bus namespace, the scope is the fully qualified domain name (FQDN), such as https://.servicebus.windows.net/.
The rights conferred by the policy rule can be a combination of:
'Send' - Confers the right to send messages to the entity
'Listen' - Confers the right to listen (relay) or receive (queue, subscriptions) and all related message handling
'Manage' - Confers the right to manage the topology of the namespace, including creating and deleting entities
The 'Manage' right includes the 'Send' and 'Receive' rights.

MS Bot framework emulator chang user id

Is there a way to change the default user id (which is 'default-user') in bot emulator?
Or maybe it supports something about multi conversations in the same time?
I want to emulate two different users at the same time (because I have multiple user types in my project.
When I try to create new conversation like this
....
var connector = new ConnectorClient(new Uri(context.Activity.ServiceUrl));
var userAccount = new ChannelAccount("//here we need to provide user id which is always default-user", "Provider");
var botAccount = context.Activity.Recipient;
var conversation = await connector.Conversations.CreateDirectConversationAsync(botAccount, userAccount);
var message = context.MakeMessage();
message.Recipient = userAccount;
message.From = botAccount;
message.Conversation = new ConversationAccount(false, conversation.Id);
await connector.Conversations.SendToConversationAsync((Activity) message);
My emulator opens new conversation in the same chat-window
Bot Framework Channel Emulator had the functions you need in the previous versions. In the latest one AFAIK changing user id and group conversation simulation are not available out of the box. However the good thing is that what this tool is doing - it is just sending http requests to your WebApi endpoint. It means that you can catch those requests using Fiddler or any other similar tool and then edit and reissue the request. It is a workaround, but for testing pusposes I think it is okay to use such an approach.
Below is the Fiddler screen and screen of debug session to show it is working:
If you want to go further and automate it - there is a REST Api documentation on botframework site, so you can build your own client.
I work on the Bot Framework Emulator. We've recently added the ability to override generated user ids to be used in conversations without the need of a tool like Fiddler. You can utilize this feature in our latest release. I hope you find this useful for your scenario.
I don't know a way of having multiple conversations with different users, but you cant change the id/name of the user that is currently sending messages.
You can do this by editing the config file that the emulator uses to store its settings.
On linux I found this settings file here:
~/.config/botframework-emulator/botframework-emulator/server.json
You'll find a section "users" in that json file.
Change that section to:
"users": {
"currentUserId": "default-user2",
"usersById": {
"default-user": {
"id": "default-user",
"name": "User"
},
"default-user2": {
"id": "default-user2",
"name": "User2"
}
}
You'll need to restart the emulator and then your conversation should be with User2 now instead of User.
When you want to change it back you just need to change:
"currentUserId": "default-user2",
back to
"currentUserId": "default-user",
On windows follow these steps:
go to directory
%APPDATA%\botframework-emulator\botframework-emulator
locate server.json file
In the sections of users replace default-user
with id you need (in my case romel)
"users": {
"currentUserId": "default-user",
"usersById": {
"default-user": {
"id": "romel",
"name": "User"
}
}
}
restart bot emulator

Accessing older GData APIs (Spreadsheet API) using OAuth 2 and a service account

The short question is whether is this possible and if so, how?
Outline
I have a .NET application which currently uses a service account to access information across a Google Apps domain using the Google Drive API. This works fine using the google-api-dotnet-client library and code along the same lines as shown in the samples here - which are currently a very good basic example of what I'm doing.
What I want to do now is extend it so as well as using those APIs provided by the "new" google-api-dotnet-client library, it uses the older "GData" libraries, as provided for via the
older google-gdata library, specifically the Spreadsheets API (and perhaps more to come).
The Problem
This is where the difficulty arises. The former library does exactly what I want, as evidenced by the second link in the first paragraph above - and the fact I have it doing it myself. HOWEVER... although the second library has been updated to support OAuth 2.0 in addition to OAuth 1.0 and the other older auth techniques, it does not - as far as I can tell from extensive Googling and trail-and-error - allow the "service account on behalf of all my users" operation which I need.
My question is whether I'm missing something (possibly a hard to find or undocumented something) which would allow me to do what I want. Failing that, is there any way I could force this behaviour and make these two libraries operate side by side?
The ideal solution
Ideally I would love some way of having the Google.GData.Spreadsheets.SpreadsheetsService instance be able to take advantage of the Google.Apis.Authentication.Auth2Authenticator<AssertionFlowClient> instance I'm already using... somehow. Is such witchcraft possible? I'm I missing the obvious?
Failing that, I'm happy to do the whole OAuth2 "assertion flow client" dance again if I have to, in some way that the older library can handle.
Help?
Other Thoughts
I have considered - and rejected for the time being - the option of starting from scratch and writing my own library to make this happen. This is for two reasons:
The gdata library already exists, and has been developed by many people likely cleverer than myself. I'm not so arrogant that I believe I can do better.
I'm not certain the OAuth2 with service account approach is even supported/allowed on these older APIs.
An alternate approach which I've been hoping to avoid but may have to fall back to depending on the answers here will be to use 2-legged OAuth 1.0 for portions of this. I'd prefer not to, as having parts of the app rely on one old auth method whilst other parts do it the nice new way just feels wrong to me. And there's that much more to go wrong...
Updates
I have considered the possibility of subclassing GDataRequestFactory and GDataRequest so I can make my own request factory and have that take the instance of Google.Apis.Authentication.Auth2Authenticator<AssertionFlowClient> (well, an instance of Google.Apis.Authentication.IAuthenticator anyway) which could step in to authenticate the request just before it's called. However... the constructor for GDataRequest is internal, which has stopped me.
It's really looking like this isn't meant to be.
For the sake of other folks coming across this question (now that the solution linked to in the accepted answer uses deprecated code), here's how I solved it:
First, start in "new API" land (use the Google.Apis.Auth nuget package) by setting up a ServiceAccountCredential following Google's Service Account example:
//In the old api, this accessed the main api accounts' sheets, not anymore
//** Important ** share spreadsheets with the Service Account by inviting the "serviceAccountEmail" address to the sheet
string serviceAccountEmail = "12345697-abcdefghijklmnop#developer.gserviceaccount.com";
var certificate = new X509Certificate2(#"key.p12", "notasecret", X509KeyStorageFlags.Exportable);
ServiceAccountCredential credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
Scopes = new[] { "https://spreadsheets.google.com/feeds", "https://docs.google.com/feeds" }
}.FromCertificate(certificate));
Tell the credential to request an Access Token:
credential.RequestAccessTokenAsync(System.Threading.CancellationToken.None).Wait();
Now it's time to switch back to "old API" land (use the Google.GData.Spreadsheets nuget package). Start by constructing the SpreadsheetsService (similar to Google's example):
SpreadsheetsService service = new SpreadsheetsService("MySpreadsheetIntegration-v1");
To use Service Account authentication, we'll create an instance of the GDataRequestFactory and set a custom Authorization header:
var requestFactory = new GDataRequestFactory("My App User Agent");
requestFactory.CustomHeaders.Add(string.Format("Authorization: Bearer {0}", credential.Token.AccessToken));
Finally, set the SpreadsheetsService's RequestFactory property to this new factory:
service.RequestFactory = requestFactory;
And go ahead and use the SpreadsheetsService as you would had you authenticated using any other technique. (Tip: share spreadsheets with the Service Account by inviting the serviceAccountEmail address to the sheet)
I managed to solve this by subclassing GDataRequestFactory and creating my own implementation of the interfaces implemented by GDataRequest. This implementation wraps an instance of GDataRequest instantiated via reflection, and adds in the necessary code to perform authentication using an instance of IAuthenticator (in my case, Auth2Authenticator).
I wrote a blog post on it and added an example as a Gist:
Blog: Using Google's Spreadsheet API using .NET, OAuth 2.0 and a Service Account
Gist 4244834
Feel free to use this if it helps you (BSD licence).
Hey just stumbled accross the same problem and produced a different solution:
Has anybody ever concidered of writing the parameters from the credentials-object directly to an OAuth2Parameters-Object?
I did this and it worked nicely:
public class OAuthTest
{
OAuth2Parameters param = new OAuth2Parameters();
public OAuthTest()
{
Debug.WriteLine("Calling: AuthGoogleDataInterface()");
bool init = AuthGoogleDataInterface();
if (init)
{
GOAuth2RequestFactory requestFactory = new GOAuth2RequestFactory(null, "My App User Agent", this.param);
//requestFactory.CustomHeaders.Add(string.Format("Authorization: Bearer {0}", credential.Token.AccessToken));
var service = new SpreadsheetsService("MyService");
service.RequestFactory = requestFactory;
SpreadsheetQuery query = new SpreadsheetQuery();
// Make a request to the API and get all spreadsheets.
SpreadsheetFeed feed = service.Query(query);
// Iterate through all of the spreadsheets returned
foreach (SpreadsheetEntry entry in feed.Entries)
{
// Print the title of this spreadsheet to the screen
Debug.WriteLine(entry.Title.Text);
}
}
Debug.WriteLine(m_Init);
}
private bool AuthGoogleDataInterface()
{
bool b_success;
try
{
Console.WriteLine("New User Credential");
// New User Credential
UserCredential credential;
using (var stream = new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read))
{
GoogleClientSecrets GCSecrets = GoogleClientSecrets.Load(stream);
string[] ArrScope = new[] { "https://spreadsheets.google.com/feeds", "https://docs.google.com/feeds" };
credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
GCSecrets.Secrets,
ArrScope,
"user", CancellationToken.None,
new FileDataStore("My.cal")).Result;
// put the Information generated for the credentials object into the OAuth2Parameters-Object to access the Spreadsheets
this.param.ClientId = GCSecrets.Secrets.ClientId; //CLIENT_ID;
this.param.ClientSecret = GCSecrets.Secrets.ClientSecret; //CLIENT_SECRET;
this.param.RedirectUri = "urn:ietf:wg:oauth:2.0:oob"; //REDIRECT_URI;
this.param.Scope = ArrScope.ToString();
this.param.AccessToken = credential.Token.AccessToken;
this.param.RefreshToken = credential.Token.RefreshToken;
}
Debug.WriteLine("AuthGoogleDataInterface: Success");
b_success = true;
}
catch (Exception e)
{
Debug.WriteLine(e.ToString());
b_success = false;
}
return b_success;
}
}
