I am writing async communication between services so if one goes down the request can't be stopped
so I am doing this scenario
I am turning off my consumer and sending message through the producer
I get a response that the message has been sent successfully
but when I run my consumer on again no message in the queue
Note :
when I don't turn off my consumer i can get my message and consume it
this is my producer code
var factory = new ConnectionFactory() { HostName = "host.docker.internal" };
using var connection = factory.CreateConnection();
using var channel = connection.CreateModel();
channel.ExchangeDeclare(exchange: "UserRequestExch", type: ExchangeType.Direct);
UserInfo userInfo = new UserInfo();
userInfo.UserID = GetCurrentUserID();
userInfo.JWT=GetCurrentUserToken();
var mess = System.Text.Json.JsonSerializer.Serialize(userInfo);
var body = Encoding.UTF8.GetBytes(mess);
string RoueKey = "";
switch (Int32.Parse(dataObject["PostponementID"].ToString()))
{
case 1:
RoueKey = "AlonePostponement";
break;
case 2:
RoueKey = "BrotherInServicePostponement";

case 9:
RoueKey = "TravelApproval";
break;
default:
return NotFound();
}
channel.BasicPublish("UserRequestExch", RoueKey, null, body);
return Ok("The request has been received and is now being processed");
my consumer code :
factory = new ConnectionFactory() { HostName = "host.docker.internal" };
connection = factory.CreateConnection();
channel = connection.CreateModel();
channel.ExchangeDeclare(exchange: "UserRequestExch", ExchangeType.Direct);
var queName = channel.QueueDeclare().QueueName;
channel.QueueBind(queue: queName, exchange: "UserRequestExch", routingKey: "TravelApproval");
var consumer = new EventingBasicConsumer(channel);
consumer.Received += (model, ea) =>
{
var recbody = ea.Body.ToArray();
var recmess = Encoding.UTF8.GetString(recbody);
UserInfo userInfo = JsonSerializer.Deserialize<UserInfo>(recmess);
var User = _context.TravelApprovalDb.Where(x => x.UserID == userInfo.UserID).FirstOrDefault();
if (User == null)
{
int ReqStatuesID = InsertRequestToDB(userInfo.UserID);
SendToExternalAPI(userInfo.JWT, ReqStatuesID);
}
else
{

}
}
channel.BasicAck(deliveryTag:ea.DeliveryTag,multiple:true);
};
channel.BasicConsume(queue: queName, consumer: consumer);
System.Console.Read();
I have applied persistent volume to the rappitMQ in docker-compose
volumes:
- rabbitmq:/var/lib/rabbitmq
or
- ~/.docker-conf/rabbitmq/data/:/var/lib/rabbitmq/
- ~/.docker-conf/rabbitmq/log/:/var/log/rabbitmq
I removed auto ack and put
channel.BasicAck(deliveryTag:ea.DeliveryTag,multiple:true);
but nothing happened

I want to call this api more than once with varient parameters. when i call once to display ProcedureRangeForm1.rdlc it run successfully , but when i call again to display ProcedureRangeForm2.rdlc throw this exception
System.FormatException: 'The header contains invalid values at index 0: 'An error occurred during local report processing.;The definition of the report 'Reports\ProcedureRangeForm1.rdl' is invalid. An unexpected error occurred in Report Processing. The process cannot access the file 'hdsktzjh.err' because it is being used by another process.''
After a lot of research, I found a solution to my question:
First, I used nuget package Tmds.ExecFunction by Execute a function in a separate process
as in this link
But I didn't get what I wanted
And then I replaced the library AspNetCore.Reporting by ReportViewerCore.NETCore
as in this link
the problem solved as this code

Outline
I am trying to implement WNS for my app game. I currently send a notification upon creation of a new user with the following function which works:
public async void SendNotificationToTag(string tag, string content)
{
var wnsToast = "<toast><visual><binding template=\"ToastText01\">"
+ "<text id=\"1\">Breaking " +content + "An WNS News!"
+ "</text></binding></visual></toast>";
WindowsPushMessage wnsMessage = new WindowsPushMessage();
wnsMessage.XmlPayload = wnsToast;
await Services.Push.HubClient.SendWindowsNativeNotificationAsync(wnsToast, tag);
Services.Log.Info("WNS TEST - SendWindowsNativeNotificationAsync - done");
}
I get a notfication to each username, i.e. a personal notificaion. I then update the tags the user listens to, looking in the hub database this also seems to work:
-Usernamecph--gameID1151--gameID1152--gameID1153--gameID1154--gameID1155--gameID1156--gameID1157--gameID1158
-gameID1157--UsernameFyn--gameID1151--gameID1153--gameID1155--gameID1156-
This check to extract the tags from the hub is done using
foreach (Microsoft.ServiceBus.Notifications.RegistrationDescription t in a)
{
string tempstring = "";
foreach (string x in t.Tags)
tempstring += "-" + x + "-";
Services.Log.Info(tempstring + t.RegistrationId + t.ETag);
}
So far so good.
When I then try to send to one of the other tags than the usernames I do not receive any notification, and I do not receive any error in the log. Am I missing something?
Update - Half Solution
If I use the server Explorer and look at the notification HUB. I can see all the tags, and I can send to them by using the test send. But I cannot seem to do it in other function calls online.
Is it something like the function has to be set as post or get?
YES
So inserting [HttpPost] Seems to enable the push.
However when I look in the Server explorer shown here on the image:
The user seems to be deleted when I update the registrations (There should be three, and there is again when I start the app with the correct tag subscriptions). So Maybe the question is How to Update a registration in the hub correctly
The current update code:
public async void updateRegistration(RegistrationDescription registration, List<string> TAGS)
{
registration.Tags = new HashSet<string>(TAGS);
try
{
var x = await hub.CreateOrUpdateRegistrationAsync(registration);
// apiServices.Log.Info(x.ExpirationTime + " " + x.Tags);
}
catch (MessagingException e)
{
ReturnGoneIfHubResponseIsGone(e);
}
}
The code that calls the function:
private async Task<bool> RegisterHubTag(User user, string Tag)
{
List<string> sendTAGs = new List<string>();
Services.Log.Info("RegisterHubTag Function");
using (Db db = new Db())
{
List<DataObjects.NotificationTag> userTags = db.NotificationTags.Where(t => t.User.UserId == user.UserId).ToList<DataObjects.NotificationTag>();
if (userTags.Count < 1)
{
//Register
RegisterController.DeviceRegistration Reg = CreateDeviceRegistration(user.PushChannelUri, sendTAGs);
Microsoft.Azure.NotificationHubs.RegistrationDescription registration = null;
//Microsoft.ServiceBus.Notifications.RegistrationDescription registration = null;
Services.Log.Info(Reg.Handle);
Services.Log.Info(Reg.Platform);
IEnumerable<string> tagsToRegister;
List<string> test = new List<string>() { user.Username };
if(Tag != user.Username)
test.Add(Tag);
tagsToRegister = test.AsEnumerable<string>();
switch (Reg.Platform)
{
case "mpns":
registration = new MpnsRegistrationDescription(Reg.Handle);
break;

registration = new WindowsRegistrationDescription(Reg.Handle);
break;

break;

}
var regID = await hub.Post(Services);
registration.RegistrationId = regID;
db.NotificationTags.Add(new DataObjects.NotificationTag() { User = user, tag = user.Username, RegistrationID = registration.RegistrationId });
hub.updateRegistration(registration, test);
db.SaveChanges();
}
else
{
RegisterController.DeviceRegistration Reg = CreateDeviceRegistration(user.PushChannelUri, sendTAGs);
Microsoft.Azure.NotificationHubs.RegistrationDescription registration = null;
//Microsoft.ServiceBus.Notifications.RegistrationDescription registration = null;
switch (Reg.Platform)

throw new HttpResponseException(HttpStatusCode.BadRequest);
}
registration.RegistrationId = userTags[0].RegistrationID;
IEnumerable<string> tagsToRegister;
List<string> test = new List<string>();
foreach (DataObjects.NotificationTag t in userTags)
test.Add(t.tag);
test.Add(Tag);
tagsToRegister = test.AsEnumerable<string>();
hub.updateRegistration(registration, test);
}
}
return true;
}
private RegisterController.DeviceRegistration CreateDeviceRegistration(string channelUri, List<string> tags)
{
return new RegisterController.DeviceRegistration() { Platform = "wns", Handle = channelUri, Tags = tags.ToArray<string>() };
}

I really do not understand it, sometimes I have three registrations, but then in the counter in the bottom is still only saying 2 ? How can this be?

In the line (*) - Task<HttpResponseMessage> actionTask = base.InvokeActionAsync(actionContext, cancellationToken);) - I have a command that intercepts an action async invoke. The variable actionTask returns with some properties. I need two of those properties filled, not null. They are:
Result -> get the StatusCode returned
Exception -> get the exception returned
I need both of those properties loaded, but I can't do a unit test where both of them are not null. In some test, Result comes not null, and other test, Exception comes not null, but never both of them.
Below is my unit test:
[TestMethod]
public void ActionAsync_Com_Exception()
{
// Arrange
Log log = null;
_loggingService.SetupSet(l => l.Licenciado = _licenciado);
_loggingService.Setup(a => a.Inserir(It.IsAny<Log>()))
.Callback<Log>((l) =>
{
log = l;
});
//Task<object> task1 = Task<object>.Factory.StartNew(() => new Exception()); //(3)
Task<object> task1 = Task<object>.Factory.StartNew(() =>
{
object myClass = new object();
return myClass;
});
//_actionDescriptor.Setup(a => a.ExecuteAsync(It.IsAny<HttpControllerContext>(), It.IsAny<IDictionary<string, object>>(), It.IsAny<CancellationToken>()))
// .Throws(new Exception("exception")); //(1)
_actionDescriptor.Setup(a => a.ExecuteAsync(It.IsAny<HttpControllerContext>(), It.IsAny<IDictionary<string, object>>(), It.IsAny<CancellationToken>()))
.Returns(task1); //(2)
DefaultControllerActionInvoker actionInvoker = new DefaultControllerActionInvoker(r => _loggingService.Object);
// Act
HttpResponseMessage response = actionInvoker.InvokeActionAsync(_baseActionContext, CancellationToken.None).Result;
// Assert
Assert.AreEqual(HttpStatusCode.InternalServerError, response.StatusCode);
Assert.AreEqual("Error", response.ReasonPhrase);
Assert.AreEqual("127.0.0.1", log.IPCliente);
Assert.AreEqual("0.0.0.0", log.IPServidor);
Assert.AreEqual("USER\\MACHINE", log.MaquinaCliente);
Assert.AreEqual("RequestInfo: POST http://localhost/teste - Error: exception ", log.Mensagem);
_loggingService.VerifySet(l => l.Licenciado = _licenciado);
_loggingService.Verify(a => a.Inserir(It.IsAny<Log>()));
_loggingService.Verify(a => a.Dispose());
}
In my test I have tried:
(1) In this case, it returns an exception, but Result property comes null.
(2) In this case, it returns a result, but Exception property comes null. In this case, I need also to mock some way, to return some error statuscode (40x or 50x). But I don´t know what to do.
(3) I have already tried creating a task which fires an exception, but gets into the case (2) above
So, I can't make my unit test works as well.
What do I need to do in my unit test code to get those two properties loaded?
Not sure I'm following what's going on in your code, but the bottom line is that you have asynchronous completion going on, for which your test assertions are not waiting. It means that the assertions are executing while or perhaps before the asynchronous code executes, so they don't test the results.
The standard test framework doesn't adequately support async/await, so if you're calling a method returning something of Task, you have to wait on the task - essentially make your test code synchronous... given what you've done, I think one extra line may do the trick:
// Act
HttpResponseMessage response = actionInvoker.InvokeActionAsync(_baseActionContext, CancellationToken.None).Result;
// After you have obtained the returned Task object,
// and done whatever will initiate the asynchronous activity, wait for it to complete...
task1.Wait(); // <-- Try this
// Assert
Assert.AreEqual(HttpStatusCode.InternalServerError, response.StatusCode);

_reader is a BinaryReader
I've got past this by using
var size = IPAddress.NetworkToHostOrder (_reader.ReadInt32 ());
var udpTunnel = new UDPTunnel { packet = _reader.ReadBytes(size) };
Now I don't know why Deserializewithlengthprefix was not working because as I understand, these lines are doing the same thing.
