IBurpExtenderCallbacks.makeHttpRequest() throws RuntimeException

August | Last updated: Nov 08, 2017 12:02AM UTC

If the network connection fails, callbacks.makeHttpRequest throws a RuntimeException. Any way we could get that method to declare that it throws a proper subclass of (presumably) IOException so we could check for and handle it in code?

Hi August, Thanks for your message. I agree, it would be better to throw some kind of IOException in this scenario. I've created a story on our development backlog for this. I'm afraid this won't get particularly high priority, and there are concerns about breaking compatibility. But we'll get to it eventually. Please let us know if you need any further assistance.

Seems like sometimes callbacks.makeHttpRequest() throws RuntimeException, other times IHttpRequestResponse.getResponse() just returns null. Here is the code: URL url = new URL(requestUrl); IHttpService service = new HttpService(url); IHttpRequestResponse ihrr = callbacks.makeHttpRequest(service, requestBytes); byte[] responseBytes = ihrr.getResponse(); I'd be interested to know which cases produce which results. In my testing I simulated a bad network connection by turning WiFi completely off. Is there a bug in the API?
