Java HttpClient: I keep getting login page back when I request a different webpage even after I had already logged in successfully -
my goal:
- post login
- get image (link) within same session , post
so far:
- i login via httppost , save cookie:
private string sessionid = ""; .... private int logintoserver() throws ioexception { int result = 0; string httpsurl = "http://192.168.1.100:8080/foo/login.jsp"; httpresponse response; closeablehttpclient httpclient = httpclients.createdefault(); httpclientcontext httpcontext = httpclientcontext.create(); try { httppost httppost = new httppost(httpsurl); list <namevaluepair> nvps = new arraylist <namevaluepair>(); nvps.add(new basicnamevaluepair("username", "*****")); nvps.add(new basicnamevaluepair("password", "*****")); httppost.setentity(new urlencodedformentity(nvps)); response = httpclient.execute(httppost,httpcontext); //store cookies cookiestore cookiestore = new basiccookiestore(); cookiestore = httpcontext.getcookiestore(); list<cookie> cookies = cookiestore.getcookies(); if(cookies != null) { for(cookie cookie : cookies) { sessionid = cookie.getvalue(); } } result = response.getstatusline().getstatuscode(); system.out.println(response.getstatusline()); httpentity entity = response.getentity(); entityutils.consume(entity); } catch (unsupportedencodingexception e) { e.printstacktrace(); } catch (malformedurlexception e) { e.printstacktrace(); } catch (ioexception e) { e.printstacktrace(); } return result; } - http/1.1 200 ok:

thank you.
i had similar experience. cookie getting rejected httpclient. solved code:
... cookiespecprovider easyspecprovider = new cookiespecprovider() { public cookiespec create(httpcontext context) { return new browsercompatspec() { @override public void validate(cookie cookie, cookieorigin origin) throws malformedcookieexception { // oh, easy } }; } }; registry = registrybuilder.<cookiespecprovider>create() .register("easy", easyspecprovider) .build(); closableclient = httpclient.setdefaultcookiespecregistry(registry).setdefaultrequestconfig(httprequestbase.getconfig()).build(); response = closableclient.execute(httprequestbase, context); ...
