How to send a post request?

fyooo | Last updated: Aug 04, 2015 02:31AM UTC

I read the document and know that we could use `makeHttpRequest` to send request. I've tried that if I used `PARAM_URL`, it success. I've read this thread before: http://forum.portswigger.net/thread/1571/send-post-requests-burp-extension However, if I change it to `PARAM_BODY`, it failed. My testing web server works well, for example: ``` $curl --data "title=hi&body=ok" http://127.0.0.1/getreq title=hi&body=ok% ``` The source code of my extender was ``` public class BurpExtender implements IBurpExtender { private static final String HOST_TO = "127.0.0.1"; @Override public void registerExtenderCallbacks(IBurpExtenderCallbacks callbacks) { callbacks.setExtensionName("Http Sender"); IExtensionHelpers helpers = callbacks.getHelpers(); try{ URL r_url = new URL("http://127.0.0.1/getreq"); byte[] report_req = helpers.buildHttpRequest(r_url); String body_encode = helpers.urlEncode("title=hi&body=ok"); callbacks.printOutput("=== body: " + body_encode); IParameter body_param = helpers.buildParameter("body", body_encode, IParameter.PARAM_BODY); report_req = helpers.addParameter(report_req, body_param); byte[] resp = callbacks.makeHttpRequest(HOST_TO, 80, false, report_req); callbacks.printOutput(new String(resp)); }catch (MalformedURLException e){ callbacks.printOutput("New URL failed"); callbacks.printOutput("exception thrown: " + e.getMessage()); } } } ```

I just read the source code of IExtensionHelpers.java, I found that `buildHttpRequest` is only use to create a `GET` request. I couldn't found a method that creates a `POST` request, `buildHttpMessage` creates full HTTP message, can it be sent by `makeHttpRequest`?
