Is there a way to catch and log badrequest or unauthorized response code from an action in web api 2?
I tried adding onactionexecuted attributefilter and ExceptionLogger but neither of them worked.
public IHttpActionResult ConfirmUpload(string val)
{
if (String.IsNullOrWhiteSpace(val))
return BadRequest(val);
}
public static void Register(HttpConfiguration config)
{
AreaRegistration.RegisterAllAreas();
config.Filters.Add(new ErrorLogAttribute());
config.Services.Add(typeof(IExceptionLogger), new ErrorLogger());
}
Any help is appreciated.
To log bad requests you can write your own LogAttribute derived from ExceptionFilterAttribute
public class LogAttribute : ExceptionFilterAttribute
{
public override void OnException(HttpActionExecutedContext context)
{
Log.Error(context.Exception);
context.Response = context.Request.CreateResponse(
HttpStatusCode.InternalServerError,
new { message = context.Exception.InnerException != null ? context.Exception.InnerException.Message : context.Exception.Message });
base.OnException(context);
}
}
HttpActionExecutedContext contains information about request so you can check request status, if you need. Attribute can be applied to controller, action
public class ValueController : ApiController
{
[Log]
public IEnumerable<object> Get()
{
}
}
or added globally
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.Filters.Add(new LogAttribute());
}
}
also all exceptions could be catched in global.asax
protected void Application_Error()
{
var ex = Server.GetLastError().GetBaseException();
// ignore 404
if (!(ex is HttpException && ((HttpException)ex).GetHttpCode() == 404))
{
Log.Fatal("Unhandled error catched in Global.asax", ex);
}
Server.ClearError();
}

I'm new to the quarkus framework where I'm writing rabbitmq-client library based on quarkur framework. I'm using io.quarkiverse.rabbitmqclient.RabbitMQClient.
I need to write JUnit for basic send and consume operations, please help me with how can I write junit and mock RabbitMQClient. I'm using the below code to send and consume message.
#ApplicationScoped
public class RabbitMQProducerAdapterImpl extends RabbitMQCongiguration implements RabbitMQProducerAdapter {
#Override
public void sendMessage(String exchange, String routingKey, String messagePayload) throws IOException {
setUpConnectionAndChannel();
channel.basicPublish(exchange, routingKey, null, messagePayload.getBytes(StandardCharsets.UTF_8));
Log.info("message sent succefully: " + messagePayload);
}
}
Here is the RabbitMQCongiguration
#ApplicationScoped
public class RabbitMQCongiguration {
#Inject
private RabbitMQClient rabbitClient;
protected Channel channel;
protected void setUpConnectionAndChannel() {
try {
// create a connection
Connection connection = rabbitClient.connect();
// create a channel
channel = connection.createChannel();
} catch (IOException e) {
throw new UncheckedIOException(e);
}
}
protected void setupQueueInDirectExchange(String exchangeName, String routingKey, String queueName,
boolean createExchangeQueues) throws IOException {
setUpConnectionAndChannel();
if (createExchangeQueues) {
this.channel.exchangeDeclare(exchangeName, BuiltinExchangeType.DIRECT, true, false, false, null);
// declaring a queue for this channel. If queue does not exist,
// it will be created on the server. this line not needed if queue already
// present
this.channel.queueDeclare(queueName, true, false, false, null);
}
// Bind Routing Key to Exchange
this.channel.queueBind(queueName, exchangeName, routingKey);
}
}
Below is the class for consumer
#ApplicationScoped
public class RabbitMQConsumerAdapterImpl extends RabbitMQCongiguration implements RabbitMQConsumerAdapter, Runnable {
private String queueName;
private MessageProcessor messageProcessor;
#Override
public void consumeMessage(String exchange, String queueName, String routingKey,
MessageProcessor messageProcessor) throws IOException {
Log.info("starting consumer...");
try {
this.queueName = queueName;
this.messageProcessor = messageProcessor;
Log.info("setting up rabbitMQPrefetchCountConfig");
setupQueueInDirectExchange(exchange, routingKey, queueName, false);
Thread consumerThread = new Thread(this);
consumerThread.start();
} catch (IOException e) {
throw new UncheckedIOException(e);
}
}
#Override
public void run() {
try {
// start consuming messages. Auto acknowledge messages.
Log.info("Start consuming messages from thread...");
channel.basicConsume(this.queueName, false, (Consumer) new DefaultConsumer(channel) {
#Override
public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties,
byte[] body) throws IOException {
String msgPayload = null;
if (body == null || body.length == 0) {
Log.warn("Invalid Message Body - Consumer Tag : " + consumerTag + ", Message DeliveryTag : "
+ envelope.getDeliveryTag());
channel.basicReject(envelope.getDeliveryTag(), false);
} else {
msgPayload = new String(body);
try {
JsonParser.parseString(msgPayload);
} catch (JsonSyntaxException ex) {
Log.error(msgPayload + " is not a valid json, Reason - ", ex);
channel.basicReject(envelope.getDeliveryTag(), false);
Log.warn("Rejected the current payload.");
return;
}
messageProcessor.processMessage(msgPayload);
channel.basicAck(envelope.getDeliveryTag(), false);
}
// just print the received message.
Log.info("Received: " + new String(body, StandardCharsets.UTF_8));
}
});
} catch (IOException e) {
throw new UncheckedIOException(e);
}
}
#ApplicationScoped
public class MessageProcessorImpl implements MessageProcessor{
#Override
public void processMessage(String messagePayload) {
Log.info("message consumed: " + messagePayload);
}
}
I have fragment:
[MvxFragmentPresentation(ActivityHostViewModelType = typeof(MyHostActivityViewModel), FragmentContentId = Resource.Id.llContainer)]
[Register("views.MyFragmentView ")]
public class MyFragmentView : MvxFragment<MyFragmentViewModel>
{
...
}
This fragment is opened (in standalone host activity) by:
var result = await NavigationService.Navigate<MyFragmentViewModel, string, string>("sample input");
Now I try to return value from MyFragment by
class MyFragmentViewModel : MvxViewModel<string, string>
{
void SomeMethod()
{
await NavigationService.Close(this, "my result");
}
...
}
but above just closes fragment from host activity and host activity stays on the screen.
Do you have recommendations how to return value from MyFragment to caller?
BTW. Maybe above should work but I spoiled sth in another place?
Thank you in advance!
I found workaround.
When MyFragmentViewModel calls await NavigationService.Close(this, "my result")
then caller of MyFragmentViewModel gets result back
but host activity stays on the screen (covering caller view).
As a workaround I manually close host activity:
class MyFragmentViewModel : MvxViewModel<string, string>
{
public event Action ReturningResult;
async void SomeMethod()
{
ReturningResult?.Invoke();
await NavigationService.Close(this, "my result");
});
...
}
[...]
public class MyFragmentView : MvxFragment<MyFragmentViewModel>
{
public override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
ViewModel.ReturningResult += delegate
{
Activity.Finish();
};
}
...
}
My problem is about this primefaces tag:
<p:selectManyCheckbox id="datasourceGroup" value="#{sessionBean.datasourceGroups}" converter="datasourceGroupConverter">
<f:selectItems value="#{sesionBean.getAllDatasourceGroups()}" var="group" itemLabel="#{group.toString()}" itemValue="#{group}" />
</p:selectManyCheckbox>
It does not render any visible output (checkboxes) at all. From logging output i know that the 'sessionBean.getAllDatasourceGroups()' method is not even called once during page refresh. only the 'sessionBean.getDatasourcegroups()' getter for the 'datasourceGroups' property is called once.
And i can't figure out what the problem is. I have very similar usecases of <p:selectManyMenu> and <p:selectOneMenu> on the same page and they work fine. So i have a basic understanding of how this works...or so i thought :-)
here are the other relevant parts of the code for reference:
SessionBean:
#ManagedBean
#SessionScoped
public class SessionBean implements Serializable {
private List<DatasourceGroup> datasourceGroups = new ArrayList<>();
public List<DatasourceGroup> getDatasourceGroups() {
return datasourceGroups;
}
public void setDatasourceGroups(List<DatasourceGroup> datasourceGroups) {
this.datasourceGroups = datasourceGroups;
}
public List<DatasourceGroup> getAllDatasourceGroups() {
List<DatasourceGroup> list = Arrays.asList(DatasourceGroup.values());
return list;
}
}
DatasourceGroup Enum:
public enum DatasourceGroup {
KUNDEN (Permission.ZugriffKunden),
INKASSO (Permission.ZugriffInkasso),
INTERESSENTEN (Permission.ZugriffInteressenten),
WARN (Permission.ZugriffWarnadressen);
private Permission permissionNeeded;
DatasourceGroup(Permission permission) {
this.permissionNeeded=permission;
}
public Permission getPermissionNeeded() {
return permissionNeeded;
}
}
And the DatasourceGroupConverter:
#FacesConverter("datasourceGroupConverter")
public class DatasourceGroupConverter implements Converter {
#Override
public Object getAsObject(FacesContext fc, UIComponent uic, String value) {
if (Toolbox.isNullOrEmpty(value))
return null;
try {
return DatasourceGroup.valueOf(value);
} catch (IllegalArgumentException e) {
throw new ConverterException(new FacesMessage(FacesMessage.SEVERITY_ERROR, "Conversion Error:",
"'" + value + "' is not a valid datasource group name"));
}
}
#Override
public String getAsString(FacesContext fc, UIComponent uic, Object object) {
if(object != null && object instanceof DatasourceGroup) {
return ((DatasourceGroup)object).toString();
}
return null;
}
}
I'm using primefaces 6.0 by the way.
I have wcf library with service contracts and implementations.

}

I have windows service project that references this library, where MyService is just an empty shell that inherits ServiceBase. This service is installed and running under local system.

IWindsorContainer container = new WindsorContainer();

string myDir;
if (string.IsNullOrEmpty(AppDomain.CurrentDomain.RelativeSearchPath))
{
myDir = AppDomain.CurrentDomain.BaseDirectory;
}
else
{
myDir = AppDomain.CurrentDomain.RelativeSearchPath;
}
var wcfLibPath = Path.Combine(myDir , "WcfDemo.dll");
string baseUrl = "http://localhost:8731/DemoService/{0}";
AssemblyName myAssembly = AssemblyName.GetAssemblyName(wcfLibPath);
container
.Register(
AllTypes
.FromAssemblyNamed(myAssembly.Name)

c.Named(c.Implementation.Name)
.AsWcfService(
new DefaultServiceModel()
.AddEndpoints(WcfEndpoint
.BoundTo(new WSHttpBinding())
.At(string.Format(baseUrl,
c.Implementation.Name)
)))), Component.For<ServiceBase>().ImplementedBy<MyService>());
}
#endregion
}
In Client Console app I have the following code and I am getting the following error:
{"Sequence contains no elements"}
static void Main(string[] args)
{
IWindsorContainer container = new WindsorContainer();
string baseUrl = "http://localhost:8731/DemoService/{0}";
container.AddFacility<WcfFacility>(f => f.CloseTimeout = TimeSpan.Zero);

c.Name.Substring(1)))
})));
var service1 = container.Resolve<IServiceProtoType>();
Console.WriteLine(service1.SayHello());
Console.ReadLine();
}
I have an idea what this may be but you can stop reading this now (and I apologize for wasting your time in advance) if the answer to the following is no:
Is one (or more) of Request, Response, or MyDemoService in the same namespace as IServiceProtoType?
I suspect that Windsor is getting confused about those, since you are doing...
Types
.FromAssemblyContaining<IServiceProtoType>()
.InSameNamespaceAs<IServiceProtoType>()
... and then configuring everything which that returns as a WCF client proxy. This means that it will be trying to create proxies for things that should not be and hence a Sequence Contains no Elements exception (not the most useful message IMHO but crushing on).
The simple fix would be just to put your IServiceProtoType into its own namespace (I often have a namespace like XXXX.Services for my service contracts).
If that is not acceptable to you then you need to work out another way to identify just the service contracts - take a look at the If method for example or just a good ol' Component.For perhaps.
How to force WCF Rest client to use Json deserializer regardless of content-type?
I am invoking a REST based web service through WCF.
The service returns JSON body, but has content-type "Application/xml". The WCF framework is now giving me the XmlException.
public class MessageFormatter : IClientMessageFormatter
{
private readonly IClientMessageFormatter _formatter;
public MessageFormatter(IClientMessageFormatter formatter)
{
_formatter = formatter;
}
public object DeserializeReply(System.ServiceModel.Channels.Message message, object[] parameters)
{
return _formatter.DeserializeReply(message, parameters);
}
}
that _formatter.DeserializeReply is throwing XmlException. I can't find any example anywhere to force json deserialization on reply.
Edit - The "message" object when moused over is throwing "{... Error reading body: System.Xml.XmlException: The data at the root level is invalid. Line 1, position 1. ...}"
That same object in another one of my project that communicate with a different REST service (Picasa web services) has a what seems like a xml serialised version of JSON object?? So the problem seems further up the stream. I need to find where this object is originating from. I'll go play around with MessageEncoder class.
Edit - (Adding more info)
public class MyBinding : WebHttpBinding
{
public MyBinding(WebHttpSecurityMode mode)
: base(mode)
{
}
public override BindingElementCollection CreateBindingElements()
{
var result = base.CreateBindingElements();
var replacements = result.OfType<MessageEncodingBindingElement>().ToList();
foreach (var messageEncodingBindingElement in replacements)
{
var index = result.IndexOf(messageEncodingBindingElement);
result.Remove(messageEncodingBindingElement);
result.Insert(index, new MyMessageEncodingBindingElement(messageEncodingBindingElement));
}
return result;
}
}
public class MyMessageEncodingBindingElement : MessageEncodingBindingElement
{
private readonly MessageEncodingBindingElement _element;
public MyMessageEncodingBindingElement(MessageEncodingBindingElement element)
{
_element = element;
}
public override BindingElement Clone()
{
var result = _element.Clone();
if (result is MessageEncodingBindingElement)
return new MyMessageEncodingBindingElement(result as MessageEncodingBindingElement);
return result;
}
public override MessageEncoderFactory CreateMessageEncoderFactory()
{
return new MyMessageEncoderFactory(_element.CreateMessageEncoderFactory());
}
}
The method CreateMessageEncoderFactory() is never called even when the constructor and Clone method are hit when breakpoints are set. Any help? I'm trying to set a custom MessageEncoder and MessageEncoderFactory class to modify the instantiation process of the Message object.
You can use a WebContentTypeMapper for that. That's a property of the WebHttpBinding, and you can customize how the deserialization will be done by the encoder from that binding, including forcing it to always use the JSON deserializer, regardless of the incoming message's Content-Type. The code below shows how this can be done.
public class StackOverflow_13225272
{
[DataContract]
public class Person
{
[DataMember]
public string Name { get; set; }
[DataMember]
public int Age { get; set; }
public override string ToString()
{
return string.Format("Person[Name={0},Age={1}]", Name, Age);
}
}
[ServiceContract]
public interface ITest
{
[WebGet(ResponseFormat = WebMessageFormat.Json)]
Person GetPerson(string responseContentType);
}
public class Service : ITest
{
public Person GetPerson(string responseContentType)
{
WebOperationContext.Current.OutgoingResponse.ContentType = responseContentType;
return new Person { Name = "John Doe", Age = 29 };
}
}
class AllJsonContentTypeMapper : WebContentTypeMapper
{
public override WebContentFormat GetMessageFormatForContentType(string contentType)
{
return WebContentFormat.Json;
}
}
public static void Test()
{
string baseAddress = "http://" + Environment.MachineName + ":8000/Service";
WebServiceHost host = new WebServiceHost(typeof(Service), new Uri(baseAddress));
host.Open();
Console.WriteLine("Host opened");
#if USE_NETFX4
// This works on .NET 4.0 and beyond
WebHttpBinding binding = new WebHttpBinding();
binding.ContentTypeMapper = new AllJsonContentTypeMapper();
#else
// This works on .NET 3.5
CustomBinding binding = new CustomBinding(new WebHttpBinding());
binding.Elements.Find<WebMessageEncodingBindingElement>().ContentTypeMapper = new AllJsonContentTypeMapper();
ChannelFactory<ITest> factory = new ChannelFactory<ITest>(binding, new EndpointAddress(baseAddress));
#endif
ChannelFactory<ITest> factory = new ChannelFactory<ITest>(binding, new EndpointAddress(baseAddress));
factory.Endpoint.Behaviors.Add(new WebHttpBehavior());
ITest proxy = factory.CreateChannel();
Console.WriteLine("With JSON: {0}", proxy.GetPerson("application/json"));
Console.WriteLine("With XML: {0}", proxy.GetPerson("application/xml"));
Console.Write("Press ENTER to close the host");
Console.ReadLine();
host.Close();
}
}
This might work.

I haven't tried it, but I think this will work. You can create a custom IClientMessageFormatter which overwrites the message format to Json, wrap that in a behavior, and then apply that behavior to your client endpoint configuration.

return _decoratedFormatter.DeserializeReply(message, parameters);
}

{
return _decoratedFormatter.SerializeRequest(messageVersion, parameters);
}
}
public class ForceJsonWebHttpBehavior : WebHttpBehavior
{
protected override IClientMessageFormatter GetReplyClientFormatter(OperationDescription operationDescription, ServiceEndpoint endpoint)
{
IClientMessageFormatter decoratedFormatter = base.GetReplyClientFormatter(operationDescription, endpoint);
return new ForceJsonClientMessageFormatterDecorator(decoratedFormatter);
}
}
