I tried to test the a set of REST services using Citrus Java DSL. After authentication the services expect the same, valid session id of the first request.
On the server side I can see, that there exists a random session-id, but at the second request, the session-id is null.
I've tried to set handleCookies to true in the endpoint configuration and tried to extract some header information (set-cookie) but without success. The EndpointConfiguration is reused during the different requests.
CitrusEndpoints.http()
.client()
.handleCookies(true)
How can I force the Endpoint to reuse the negotiated session-id or how can I extract it from the request / response?
Thanks in advance for any ideas and hints.
The response to your 1st request should have a header set
Set-Cookie: JSESSIONID=ABCDEFG;path=/api/foo
You can extract this information in your receive operation
http()
.client(todoClient)
.receive()
.response(HttpStatus.OK)
.extractFromHeader("Set-Cookie", "cookie")
.payload("{ \"foo\": \"bar\" }");
After that we have to post process the new ${cookie} value in order to extract the actual session id name and value into a new variable ${sessionId}.
createVariable("sessionId", "citrus:substringBefore(${cookie}, ';')");
Now we have a variable ${sessionId} that only contains the name and value of the session id - in our example this is JSESSIONID=ABCDEFG.
In further requests you can use the variable in order to set proper Cookie header information
http()
.client(todoClient)
.send()
.get("/api/foo")
.header("Cookie", "${sessionId}")
.accept(ContentType.APPLICATION_JSON.getMimeType());

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));
A parse server cloud function is defined via
Parse.Cloud.define("hello", function(request, response) {..});
on the response, I can call response.success(X) and response.error(Y), and that sets the http response code and the body of the response.
But how do I define a different code, like created (201)?
And how do I set the headers of the response?
thanks, Tim
You are allowed to return any valid JSON from response.success(). Therefore, you could create an object with fields such as code, message, and value, so you can set the code, give it a string descriptor, and pass back the value you normally would, if there is one. This seems to accomplish what you need, though you will have to keep track of those codes across your platforms. I recommend looking up standard http response codes and make sure you don't overlap with any standards.
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.
Is there an option to set cookies while using rest client in Pentaho 5.1?
I read a couple of blogs and it wasnt mentioned anywhere.
I have tried using curl using shell job entry. Got the cookie and used it in my next curl to get data.
I need to do a similar process using rest client transformation entry.
Please let me know if there are any leads I can follow.
i dont know if you can do that with this step, but with the http client step you can set you own http request headers. This works because i use this way.
if you can use the http client step instead the rest client do this:
add a new Script step (the javascript step) and add this js code to your trans (these are sample headers, the most interesting for you is the last one):
//set the headers to next step
var header_accept_charset = "utf-8";
var header_cache_control = "max-age=0";
var header_user_agent = "batman browser";
lal = "lalvalue_fooo";
lel = "lelvalue_meeeh";
var cookie = "lol="+ lol +"; lal="+ lal;
Now make sure the vars are passed to the next step, the http client (click on get variables to fill the rows of "fields"), this should works.
The cookie is just another request header, a string simply built with the concatenation of variables and values with semicolons.
PD:Maybe this method works with the Rest Client step, if works also with this step let me know, i am interested to know that.
I have a Pyramid application where I have the following line of code:
return HTTPFound(location=request.route_url('feeds'))
However I want to pass an extra parameter in the headers. Im trying with this:
headers = {"MyVariable": "MyValue"}
return HTTPFound(location=request.route_url('feeds'),headers=headers)
However the view_config of "feeds" does not get MyVariable in the headers. I'm checking it with the following code:
print "**************"
for key in request.headers.keys():
print key
print "**************"
What am I doing wrong?
headers is meant to be a sequence of (key, value) pairs:
headers = [("MyVariable", "MyValue")]
This lets you specify a header more than once. Also see the Response documentation, the headers keyword is passed on as headerlist to the Response object produced. Also see the HTTP Exceptions documentation:
headers:
a list of (k,v) header pairs
However, headers are only sent to the client; they are not passed on by the client to the next request that they are instructed to make. Use GET query parameters if you need to pass information along to the redirection target, or set values in cookies or in the session instead.
To add on query parameters, specify a _query directory for route_url():
params = {"MyVariable": "MyValue"}
return HTTPFound(location=request.route_url('feeds', _query=params))
and look for those query parameters in request.GET:
for key in request.GET:
print key, request.GET.getall(key)
Due to the way HTTP works, what you are asking is not possible. You can use either GET parameters to pass the data, or you can store the data in a cookie instead.
