Java HtmlUnit - can't login to wordpress

Question

I'm trying to use HtmlUnit to login to my local wordpress website but it seems to have a cookies issue.

That's that begining of the code:

WebClient webClient = new WebClient();
HtmlPage loginPage = webClient.getPage("http://localhost/flowersWp/wp-admin");
HtmlForm form = loginPage.getFormByName("loginform");

That's what I get in the log. Anyone has an idea? Thanks.

Illegal path attribute "/flowersWp/wp-admin". Path of origin: "/flowersWp/wp-login.php"

Answer 1

WebClient is using apache httpclient, so it is an HttpClient problem.

From my experience, it has to do with redirections. I've gotten rid of this problem using HttpClient and registering my own cookie support:

  // Create a local instance of cookie store
  CookieStore cookieStore = new BasicCookieStore();

  // Bind custom cookie store to the local context
  httpclient.setCookieStore(cookieStore);
  CookieSpecFactory csf = new CookieSpecFactory() {
      public CookieSpec newInstance(HttpParams params) {
          return new BrowserCompatSpec() {
              @Override
              public void validate(Cookie cookie, CookieOrigin origin)
              throws MalformedCookieException {
                // Oh, I am easy.
                // Allow all cookies
                log.debug("custom validate");
              }
          };
      }
  };
  httpclient.getCookieSpecs().register("easy", csf);
  httpclient.getParams().setParameter(
       ClientPNames.COOKIE_POLICY, "easy"); 

Well, in HtmlUnit I have no direct access to httpclient, but I'm thinking of changing its source code to do so, as I need to connect to wordpress with JavaScript support.

I must note that in HttpClient 4+, I had to do the following:

        CookieSpecProvider csf = new CookieSpecProvider() {
            @Override
            public CookieSpec create(HttpContext context)
            {
                return new BrowserCompatSpec() {
                    @Override
                    public void validate(Cookie cookie, CookieOrigin origin)
                        throws MalformedCookieException
                    {
                        // Allow all cookies
                    }
                };
            }
        };

        RequestConfig requestConfig = RequestConfig.custom()
            .setCookieSpec("easy")
            .build();

        httpclient = HttpClients
            .custom()
//          .setHostnameVerifier(SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER)
            .setDefaultCookieStore(cookieStore)
            .setDefaultCookieSpecRegistry(RegistryBuilder.<CookieSpecProvider>create()
                                              .register(CookieSpecs.BEST_MATCH, csf)
                                              .register(CookieSpecs.BROWSER_COMPATIBILITY, csf)
                                              .register("easy", csf).build())
            .setDefaultRequestConfig(requestConfig)
//          .setSSLSocketFactory(sslsf)
            .build();
