At times, when client sends an incorrect data to a API COntroller method, the request object become NULL when received. The primary cause of request object turning NULL could be client passing NULL value to a Non-Null property etc etc.
I would like to get that actual request object which client had sent so that I can get to know what client has passed and resolve the issue.
I receive my request object as:
HttpPost]
[Route("addQuote")]
public JsonResult AddQuote([FromBody]AddQuoteRequestModel quoteRequestModel) { //Lines of code }
Here, at times the quoteRequestModel object is received as NULL. I would like to capture the exact JSON client has passed in to this method.
Is there any way I can capture that?

I'm trying to send int response but get an error but when I use both as a string then response get successfully.
post("/employee") {
call.respond(mapOf("hey" to "Hey","if" to 1))
}

You can't pass different types in response "yet" like mentioned in stacktrace. As a workaround you can pass 1 as string or create custom class for this response and serialize it to json and send it like that
This article, https://devblogs.microsoft.com/aspnet/improvements-in-net-core-3-0-for-troubleshooting-and-monitoring-distributed-apps/, tells me that the field TraceId is available as a correlation id, which is great!
info: Microsoft.AspNetCore.Routing.EndpointMiddleware[1]
=> ConnectionId:0HLR1BR0PL1CH
=> RequestPath:/weatherforecastproxy
RequestId:0HLR1BR0PL1CH:00000001,
SpanId:|363a800a-4cf070ad93fe3bd8.,
TraceId:363a800a-4cf070ad93fe3bd8,
ParentId: Executed endpoint 'FrontEndApp.Controllers.WeatherForecastProxyController.Get
(FrontEndApp)'
In fact, I can see that in our log sink this works as advertised: When web application A serves a request and in doing so invokes web application B, both of them write the same TraceId value to the log.
As far as I understand, any ASP.NET Core application that receives an incoming Request-Id header will attach the same header to outgoing requests, but if the header does not exist on the incoming request, an new value will be generated for the outgoing request.
We have been asked to add that value to the response from web application A, but it is (not surprisingly) not available on the incoming request.
I have been looking at the System.Diagnostics.Activity class, but accessing Activity.Current isn't giving me an instance with anything useful - the TraceID is just {} - i.e. empty.
My question is this: How can I access the TraceId value in the context of a web application?
-S
I had the same problem when I tried to add a header with TraceId value.
Doing some tests with ModelValidation, I saw then in this kind of error response the "traceId" value was correct, but I couldn't obtain this value from http context variable in any way.
Then I went to net core source code to see DefaultProblemDetailsFactory implementation and surprise! The "traceId" value is obtained doing this:
var traceId = Activity.Current?.Id ?? httpContext?.TraceIdentifier;
Yes, you can get THE traceId using Activity static variable.
You can get tracid and spanid in dictionary.
using var subject = _tracer.BuildSpan($"Operation").StartActive();
var spanContext = subject.Span.Context;
var dictionary = new Dictionary<string, string>();
_tracer.Inject(spanContext, BuiltinFormats.TextMap, new TextMapInjectAdapter(dictionary));
Is there any way to use the response of a wcf service method request as an input for the next request in same orchestration and return the response of the first request as well as the response of the second request as out put in BizTalk?
Eg :
My first request gives a response as "a"
Give this response "a" as request to the 2nd request and gets the response as "b"
Return the response as "a" and "b".
Is this possible?
Yes. You could either create a map from Response 1 to Request 2, and also create a multiple input message map from Response 1 and Response 2 to your final output message.
If the messages involved don't have any repeating structures, it may be enough to distinguish the fields that you need to be concerned with and just use a ConstructMessage with an XmlDocument, i.e.
// construct shape code
varXmlDoc = new System.Xml.XmlDocument();
varXmlDoc.LoadXml("<webSvcRequest2 xmlns=''><ParamB>" + msgWebSvcResp1.ParamA + "</ParamB></webSvcRequest2>");
msgWebSvcReq2 = varXmlDoc;
And similar code for producing the final output message. If you go this route, I'd advice creating some C# utility methods to actually store the strings/message templates.
I am using WorkContext that contains information about the current request such as logged-in user, current culture and so on;
My question is i want to Interrogates HttpContext.Current to get data from request;(Method Body; i already know how to get it from query string) i mean i want to get Jason Data that is passed when the user make the request in case of Get,Post,Put and Delete requests; note i want to get data from raw url HttpContext.Current.Request not receive data in a method paraemeter as i want to get generic data that is common on all methods
I think the property you want (assuming I understood your question) is HttpContext.Current.Request.RequestType. If you wanted Json you could do:
var rType = new { Method = HttpContext.Current.Request.RequestType };
var thing = JsonConvert.SerializeObject(rType);
I am using RestSharp in ASP .NET MVC 2 project. Trying to create RestRequest (using POST method) and add two enum values (my enum type -- OrderStatusFlags) to request body -- using build-in RestSharp XmlSerializer:
var request = new RestRequest("orders/{vendorID}/{number}", Method.POST);
request.AddBody(previousOrderStatus);
request.AddBody(newOrderStatus);
But after calling AddBody method in request parameters can see only empty but no value. And while calling MVC action method an error occurs:
The parameters dictionary contains a null entry for parameter 'previousStatus' of non-nullable type 'OrderStatusFlags' for method 'RestResponse PostOrderStatus(Int32, System.String, OrderStatusFlags, OrderStatusFlags)' in 'OrdersResourceEndpoint'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters
Enum look like this:
public enum OrderStatusFlags : long
{
Pending,
Confirmed,
...
}
Does anybody occurs a similiar situation?
A couple issues here. First, you can only call AddBody() once or the last call will take precedence. AddBody() is also only for sending XML as the request body. What is the required XML schema that you need to send to that URL? Can you post some sample XML that you're trying to generate?
I think more likely you actually want to use AddParameter() to add some POST parameters since that is far more common than XML request bodies.
