Service Virtualization

Hi,

I was trying to modify the user name and password from the request calling virtual service (lisa.vse.request)

To achieve i used the following code in dph filter

---------------------------------------------------------------------------------------------------------------------

String usernameStart="<wsse:Username>";

String usernameEnd="</wsse:Username>";

String passwordStart="#PasswordDigest\">";

String passwordEnd="</wsse:Password>";

String theBody = lisa_vse_request.getBodyText();

if (theBody.contains(usernameStart)) {

  usernameBody=theBody.substring(theBody.indexOf(usernameStart),theBody.indexOf(usernameEnd)+usernameEnd.length());

  passwordBody=theBody.substring(theBody.indexOf(passwordStart),theBody.indexOf(passwordEnd)+passwordEnd.length());

theBody = theBody.replace(usernameBody, "<wsse:Username>MODIFIEDRaku</wsse:Username>");

  theBody = theBody.replace(passwordBody, "#PasswordDigest\">MODIFIEDpassword=</wsse:Password>"); 

  testExec.setStateValue("lisa.vse.request", theBody);

}

but i noticed its changing the request body where as the lisa.vse.request still holds the old request

in lisa as designed - the internal structure of the request property is (request+metadata) + (request body)

Kindly let me know is there any inbuilt function available to modify entire request property ?

Thanks,

Hi Ravi

I am not able to understand what you are trying to achieve here. If username and password are arguments use the code to set arguments not the body.

eg:

ParameterList pl = lisa_vse_request.getArguments();

  String Username = pl.getParameter("username");

You can user setParameterValue

pl.setParameterValue(key, value)

if not, username and password are part of body then use setbody to set the body only. Don't use setStateValue.

lisa_vse_request.setBody(arg0);

Hope that helps.

HI Monika,

Thanks for looking into this issue, I am trying to modify the request message reaching Virtual service (VSM) before sending it to other system (live system)

I am using lisa as a router to redirect all the request reaching to VS - I am trying send the modified request message to live system.

request.setBody will change only in request body, I am trying to send the modified request (request+metadata) + (request body) to other system.

Use RDM to modify metadata.

can u share sample request?

1. Request

2. Expected modified request after applying scriptable protocol.

You can use any sample request and response:

Client ---request msg---->Server

Client----req---->Lisa---modified req----->Server

create 2 VS - one as router and other as actual server

------sample req-----

Hi Ravi,

Once the request flows into virtual service, the request content,header information etc, which will store in property com.itko.lisa.vse.http.HTTPTransaction as mentioned below.

com.itko.lisa.vse.http.HTTPTransaction[method=POST, uri=/, httpVersion=1.1, headers=User-Agent=Fiddler&Host=localhost:8081&Content-Length=973, request content=<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wssu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <soapenv:Header>

        <wsse:Security>

            <wsse:UsernameToken>

                <wsse:Username>user</wsse:Username>

                <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">mypassword=</wsse:Password>

                <wsse:Nonce>NjQ3OTA5MzI4NzU=</wsse:Nonce>

            </wsse:UsernameToken>

        </wsse:Security>

    </soapenv:Header>

    <soapenv:Body>

        <Add xmlns="http://Example.org">

      <!--a is optional-->

            <a>1</a>

      <!--b is optional-->

            <b>1</b>

        </Add>

    </soapenv:Body>

</soapenv:Envelope>]

use the below code to construct the logic as per your requirement.

import com.itko.lisa.vse.http.HTTPTransaction;

import com.itko.lisa.vse.http.Transaction;

HTTPTransaction transaction = ((HTTPTransaction) testExec.getStateObject("lisa.vse.http.current.transaction"));

construct the logic to replace the username and password values as per your requirement

transaction.getRequestContentAsString().replace("username", "u");

transaction.getRequestContentAsString().replace("password", "p");

testExec.setStateObject("lisa.vse.http.current.transaction",transaction);

return testExec.getStateValue("lisa.vse.http.current.transaction");

if you run your VSM in ITR you shall see the requestContent updated.

Hello Ravi,

          Please see the below link for a solution that i used when i faced a similar situation and let us know if it helps.

Re: Modify argument values in request to send in LIVE SYSTEM/Image Validation mode?

Thanks,

Surya.

Ravi -- were you able to solve your challenge with the solutions offered?

Yes, As VSE request is immutable , We created 2 VSMs to modify the request and forwarded the modified request to actual downstream system.
