Here is the code:
private AccessTokenInfo GetToken()
{
WebRequest webRequest = WebRequest.Create("https://oxford-speech.cloudapp.net/token/issueToken");
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = "POST";
byte[] bytes = Encoding.ASCII.GetBytes(_requestDetails);
webRequest.ContentLength = bytes.Length;
try
{
using (Stream outputStream = webRequest.GetRequestStream())
{
outputStream.Write(bytes, 0, bytes.Length);
}
// ...
I have got the exception:
the underlying connection was closed could not establish trust relationship
How can I fit it ?
I hope I'm not missing something here...
The URL you're using isn't the one that generates tokens for the Text-to-Speech API as documented here. (The "Oxford" that's referenced in your URL refers to the Project Oxford which Cognitive Services was formerly known as.)
Also, WebRequest is deprecated. Use the System.Net.Http package instead.
The code to invoke the new REST endpoint then would look something like:
using (var client = new HttpClient())
using (var request = new HttpRequestMessage(HttpMethod.Post, "https://api.cognitive.microsoft.com/sts/v1.0/issueToken"))
{
request.Headers.Add("Ocp-Apim-Subscription-Key", "YOUR-KEY-HERE");
var response = await client.SendAsync(req);
var token = await response.Content.ReadAsStringAsync();
}
Finally, there are several client libraries that may get you around from writing any code to hit the REST services at all.

I am having the following problem and an extensive search online didn't provide any good results.
When trying to access my Azure Data Explorer Database and querying using the Kusto.Data SDK in an Azure Function, it yields the following error:
Kusto client failed to send a request to the service: 'An unknown, invalid, or unsupported option or level was specified in a getsockopt or setsockopt call.'
However, running the Function on my local machine, everything works fine.
Edit: The function excepts at using (var reader = await queryProvider.ExecuteQueryAsync(Database, query, clientRequestProperties))
EDIT2 - SOLUTION:
You can downgrade the NuGet Kusto.Data Package to Version 9.4.1, this solves the problem and doesn't throw any error anymore. If you still encounter difficulties, you can try to directly access the ADX database via http requests:
const string tenantId = "<tenantId>";
const string client_id = "<clientId>";
const string client_secret = "<client_secret>";
const string Cluster = "<cluster_adress";
const string Database = "<database_name>";
var authUrl = "https://login.microsoftonline.com/<tenantId>/oauth2/token";
var param = new Dictionary<string, string>
{
{"client_id",client_id},
{"grant_type","client_credentials"},
{"client_secret",client_secret},
{"resource","https://help.kusto.windows.net"}
};
var data = new FormUrlEncodedContent(param);
using var authClient = new HttpClient();
var response = await authClient.PostAsync(authUrl, data);
string result = response.Content.ReadAsStringAsync().Result;
//parse result
var resultJson = System.Text.Json.JsonDocument.Parse(result);
//retrieve access token
var accessToken = resultJson.RootElement.GetProperty("access_token");
//-----------------------------------------------------------------------------------------------
var dataXUrl = Cluster + "/v1/rest/query";
var database = Database;
var dataXQuery = "sample_table| where Time > ago(2min)";
var body = new Dictionary<string, string>
{
{"db",database},
{"csl",dataXQuery}
};
using var dataXClient = new HttpClient();
dataXClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken.ToString());
dataXClient.DefaultRequestHeaders.Add("Accept", "application/json");
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, dataXUrl);
request.Content = new StringContent(JsonConvert.SerializeObject(body), Encoding.UTF8, "application/json");
var table = await dataXClient.SendAsync(request);
//pretty print
var obj = JsonConvert.DeserializeObject(table.Content.ReadAsStringAsync());
var tableJSON = JsonConvert.SerializeObject(obj, Formatting.Indented);
log.LogInformation("\n\n" + tableJSON);
I am having the same issue on a continuous webjob on an Azure App Service. The Kusto nuget version I am using is 10.1.0
Downgrading to nuget 9.4.1 solved the problem immediately.
FYI - This only seems to affect 10.1.0. The earlier 10.x.x versions should work.
The ADX team believes they will have this fixed in the next nuget version.
I want to authorize an OAuth JSON Web Token granted by Azure Active Directory, and one thing I need to do is get more information about the application in the token's appId using the Microsoft Graph API.
Microsoft Graph API allows me to GET an app by its id via
https://graph.microsoft.com/beta/applications/{id}
, but NOT by its appId via
https://graph.microsoft.com/beta/applications/{appId}
The best way I see to use Microsoft Graph API to GET an app using its AppId is via a filter like so:
https://graph.microsoft.com/beta/applications?filter=appId eq '{appId}'
The above filter works just fine in the Microsoft Graph Explorer, but when calling the Graph API using a GET request using HttpUrlConnection, my request fails with HTTP Code 400 and message "Bad Request".
It's weird because using the exact same HttpUrlConnection to GET the full range of applications via
https://graph.microsoft.com/beta/applications
works just fine.
Is there something about the filter functionality that I can't use it in a Microsoft Graph API GET request? How should I get info on an app by its AppId?
Here is a snippet of the Java code I am using for my HttpURLConnection:
url = new URL(String.format("https://graph.microsoft.com/beta/applications?filter=appId eq '%s'", appId));
final HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setRequestProperty("Authorization", "Bearer " + result.getAccessToken());
conn.setRequestProperty("Accept", "application/json");
conn.setRequestProperty("Content-Type", "application/json");
final int httpResponseCode = conn.getResponseCode();
if (httpResponseCode == 200 || httpResponseCode == 201) {
BufferedReader in = null;
final StringBuilder response;
try {
in = new BufferedReader(
new InputStreamReader(conn.getInputStream()));
String inputLine;
response = new StringBuilder();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
} finally {
in.close();
}
final JSONObject json = new JSONObject(response.toString());
return json.toString(4);
} else {
return String.format("Connection returned HTTP code: %s with message: %s",
httpResponseCode, conn.getResponseMessage());
}
In case someone else comes looking for this, if you are using the GraphServiceClient you can do this:
var appId = "some app id";
var response = await _graphClient.Applications
.Request()
.Filter($"appId eq '{appId}'")
.GetAsync();
var azureAddApplication = response.FirstOrDefault() ?? throw new ArgumentException($"Couldn't find App registration with app id {appId}");
In case someone is searching this... the API call should be done with the app's Object ID, not the app ID.
You should URLEncode the query parameters.
String url2=URLEncoder.encode("$filter=appId eq '{applicationId}'");
URL url = new URL("https://graph.microsoft.com/beta/applications?"+url2);
I have a .NET Web API that I am using to do some interaction with Microsoft Graph and Azure AD. However, when I attempt to create an extension on the user, it comes back with Access Denied.
I know it is possible from the documentation here however, it doesnt seem to work for me.
For the API, I am using client credentials. So my web app authenticates to the API using user credentials, and then from the API to the graph it uses the client.
My app on Azure AD has the Application Permission Read and Write Directory Data set to true as it states it needs to be in the documentation for a user extension.
I know my token is valid as I can retrieve data with it.
Here is my code for retrieving it:
private const string _createApprovalUrl = "https://graph.microsoft.com/beta/users/{0}/extensions";
public static async Task<bool> CreateApprovalSystemSchema(string userId)
{
using(var client = new HttpClient())
{
using(var req = new HttpRequestMessage(HttpMethod.Post, _createApprovalUrl))
{
var token = await GetToken();
req.Headers.Add("Authorization", string.Format("Bearer {0}", token));
req.Headers.TryAddWithoutValidation("Content-Type", "application/json");
var requestContent = JsonConvert.SerializeObject(new { extensionName = "<name>", id = "<id>", approvalLimit = "0" });
req.Content = new StringContent(requestContent, Encoding.UTF8, "application/json");
using(var response = await client.SendAsync(req))
{
var content = await response.Content.ReadAsStringAsync();
ApprovalSystemSchema schema = JsonConvert.DeserializeObject<ApprovalSystemSchema>(content);
if(schema.Id == null)
{
return false;
}
return true;
}
}
}
}
Is there anyone who may have a workaround on this, or information as to when this will be doable?
Thanks,
We took a look and it looks like you have a bug/line of code missing. You appear to be making this exact request:
POST https://graph.microsoft.com/beta/users/{0}/extensions
Looks like you are missing the code to replace the {0} with an actual user id. Please make the fix and let us know if you are now able to create an extension on the user.
I can't use the ServiceStack Client libraries and I've chosen to use the HttpClient PCL library instead. I can do all my Rest calls (and other json calls) without a problem, but I'm now stucked with uploading files.
A snippet of what I am trying to do:
var message = new HttpRequestMessage(restRequest.Method, restRequest.GetResourceUri(BaseUrl));
var content = new MultipartFormDataContent();
foreach (var file in files)
{
byte[] data;
bool success = CxFileStorage.TryReadBinaryFile(file, out data);
if (success)
{
var byteContent = new ByteArrayContent(data);
byteContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = System.IO.Path.GetFileName(file) ,
};
content.Add(byteContent);
}
}
message.Content = content;
Problem is now that I get a null reference exception (status 500) when posting. I doesn't get into the service. I see the call in the filterrequest, but that's it.
So I'm wondering what I do wrong and how I can pinpoint what is going wrong. How can I catch the correct error on the ServiceStack layer?
The web socket is written in javascript by my colleague. I managed to connect. First of all I have to log in on the application using a test account. I have to send the email and password through a json. I have installed the Json.Net packet using NuGet.
Some code that I found on my reaserch is this, but I do not understand how to send my data using that segment.
var buffer = new byte[1024];
var segment = new ArraySegment<byte>(buffer);
webSocket.SendAsync(segment, WebSocketMessageType.Text, true, CancellationToken.None);
Of course, I can use an object
User user=new User();
user.Email="bla#bla.com";
user.Password="pass";
string json = JsonConvert.SerializeObject(user);
But it will not be of any use because the method SendAsync accepts only byte type on segment.
All I want is to send that data, and if log in succeeds, I should receive other data (in Json format) about the user.
As a side note, I am quite new to web sockets, I used http protocols from ASP.NET WEB API 2.
I have no idea about Windows Phone 8, but by the code you pasted it seems similar to the regular .NET ClientWebSocket, so here you have some examples:
public static Task SendString(ClientWebSocket ws, String data, CancellationToken cancellation)
{
var encoded = Encoding.UTF8.GetBytes(data);
var buffer = new ArraySegment<Byte>(encoded, 0, encoded.Length);
return ws.SendAsync(buffer, WebSocketMessageType.Text, true, cancellation);
}
public static async Task<String> ReadString(ClientWebSocket ws)
{
ArraySegment<Byte> buffer = new ArraySegment<byte>(new Byte[8192]);
WebSocketReceiveResult result = null;
using (var ms = new MemoryStream())
{
do
{
result = await ws.ReceiveAsync(buffer, CancellationToken.None);
ms.Write(buffer.Array, buffer.Offset, result.Count);
}
while (!result.EndOfMessage);
ms.Seek(0, SeekOrigin.Begin);
using (var reader = new StreamReader(ms, Encoding.UTF8))
return reader.ReadToEnd();
}
}
If something does not compile or exists in WP8, just find an equivalent.
#vtortola is a working example in case your data comes in multiple segmented messages, but if all data comes in a single message you don't need all those streams to read the message, you just need to do this:
public static async Task<String> ReadString(ClientWebSocket socket)
{
var reciveBuffer = new byte[32000];
var result = await socket.ReceiveAsync(new ArraySegment<byte>(reciveBuffer), CancellationToken.None);
if (result.MessageType == WebSocketMessageType.Close)
{
await socket.CloseAsync(WebSocketCloseStatus.NormalClosure, string.Empty, CancellationToken.None);
}
return Encoding.ASCII.GetString(reciveBuffer , 0, result.Count);
}
If your message is splited in multiple segments or you don't know how your message is comming then you have to do like #vtortola
Also if you want to keep receiving messages you can do a while and call ReadString inside, like this:
while (socket.State == WebSocketState.Open)
{
var msg = ReadString(socket)
//do something with your message...
}
