我已多次分析浏览器和服务器之间的通信，但仍无法找到原因

  public boolean Login(String user, String pass, String url) {
    try {
        DefaultHttpClient httpclient;
        HttpParams params = new BasicHttpParams();
        ConnManagerParams.setMaxTotalConnections(params, 100);
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);

        // Create and initialize scheme registry
        SchemeRegistry schemeRegistry = new SchemeRegistry();
        schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        schemeRegistry.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));
        // Create an HttpClient with the ThreadSafeClientConnManager.
        // This connection manager must be used if more than one thread will
        // be using the HttpClient.
        ClientConnectionManager cm = new ThreadSafeClientConnManager(params, schemeRegistry);
        httpclient = new DefaultHttpClient(cm, params);

        String loginHTML = httpSession.Get(url);

        for (Cookie c : httpSession.cs.getCookies()) {
            httpclient.getCookieStore().addCookie(c);
        }

        Document doc = Session.GetDocument(loginHTML, url);

        List<NameValuePair> nvps = new ArrayList<NameValuePair>();
        hm.put("session_login", user);
        hm.put("session_password", pass);
        hm.put("duration", "0");

我使用HTMLUnit解决了这个问题。

   public boolean Login(String user, String pass, String url) {
        try {
            final WebClient webClient = new WebClient();

            // Get the first page
            final HtmlPage page1 = webClient.getPage(url);

            // Get the form that we are dealing with and within that form,
            // find the submit button and the field that we want to change.
            final HtmlForm form = page1.getFormByName("oauthAuthorizeForm");

            final HtmlSubmitInput button = form.getInputByName("authorize");
            final HtmlTextInput textField = form.getInputByName("session_login");
            final HtmlPasswordInput textField2 = form.getInputByName("session_password");
            // Change the value of the text field
            textField.setValueAttribute(user);
            textField2.setValueAttribute(pass);

            // Now submit the form by clicking the button and get back the second page.

            final HtmlPage page2 = button.click();
            String newurl = page2.getUrl().toString();
            String oauthVerifier = newurl.split("oauth_verifier=")[1].split("&")[0];
            accessToken = oauthService.getOAuthAccessToken(requestToken, oauthVerifier);

            webClient.closeAllWindows();
            logined = true;
            return true;

        } catch (Exception ex) {
            Logger.getLogger(ClassLinkedIn.class.getName()).log(Level.SEVERE, null, ex);
        }
        return false;
    }

但请记住，您需要使用HTMLUnit的最新版本，而不是sf.net上的版本这也不是一个完美的解决方案。它可以工作，但在网页和其他人的javascript \ css上花了很多钱
