buildParameter not working

vino | Last updated: Aug 08, 2019 08:46PM UTC

I built the HttpRequest using buildHttpMessage method and trying to add Cookie and Body param using LegacyBurpExtender.getInstance().getHelpers().buildParameter and addParameter and updateParameter methods and it is not working. Below is the code snippet, buildRequest = helpers.buildHttpMessage(headers,bodyObject.toString().getBytes()); IParameter testParam = helpers.buildParameter("test","testing",PARAM_BODY); buildRequest = helpers.updateParameter(buildRequest, testParam); String requestString = LegacyBurpExtender.getInstance().getHelpers().bytesToString(buildRequest); When I convert bytes to string I dont see new body param. I tried with update Param as well.

We have a bit of a backlog in terms of Extensions issues. Please accept our apologies, we'll get back to you as soon as we can.

Unfortunately, we don't currently have an update. We are still working through a backlog. We will update you when we have something to share.

Any update on this?

Hi Vino, We apologize for the delay in responding to your post. Is there any reason why you are using the LegacyBurpExtender as opposed to the methods provided in the current IExtensionHelpers interface? It could be why the casting is not working as intended.
