HttpCore - getting POST parameters
Hi,
I'm trying to create a simple HTTP server with HttpCore 4.1 but I can't figure out how to get parameters from HTTP POST requests. For instance I want to handle the POST request generated by this HTML code:
<form action="/login" method="POST">
<input type="text" name="user" />
<input type="password" name="pass" />
</form>
I have an implementation of HttpRequestHandler and in my
void handle(HttpRequest request, HttpResponse response, HttpContext context) throws HttpException, IOException
I have something like this:
request.getParams().getParameter("user")
which returns null...
I guess HttpParams is something different than what I think it is?
Is what I'm trying to do supported? And if yes, what's the right way to do it?
thank you.
regards,
mgp

Hi
If a client send a request like "http://example.org/path/to/file?a=1&b=2&c=3
".
How do I get name / value pairs from that.
Frankly, I don't know how to get HttpEntity from the RequestHandler.
I tried request.getRequestLine().getUri(), but it only returned the path
part, like "/file".
Thanks

Yes, it is. Those are parameters that define protocol specific aspects
(such as HTTP version, etc) and not form parameters

HttpCore is a set of low level HTTP transport components and as such
does not provide methods for processing content. You can, however, use
URLEncodedUtils class from HttpClient to parse an HTTP entity into a set
of name / value pairs.
Hope this helps
