Apache HttpClient to access facebook

Question

Any examples, tips, tricks for the following scenario?

I used Apache HttpClient to simulate browser functionality for accessing facebook through a java application. To do this, I must first provide the user credentials. I used the examples provided on the following website.

http://svn.apache.org/viewvc/httpcomponents/oac.hc3x/trunk/src/examples/

But not these methods work for facebook, the next one is the test code that I wrote for this purpose. I did not provide all the written methods, here is only the method used to log in to your facebook account. relays appreciate any help

    private static int connectAndLogin(String email, String pass){
    logger.trace("Facebook: =========connectAndLogin begin===========");

    String httpResponseBody = getMethod("http://www.facebook.com/login.php");
    if(httpResponseBody == null){
        //Why don't we try again?
        try
        {
            Thread.sleep(1000);
        }
        catch (InterruptedException e)
        {
            logger.trace(e.getMessage());
        }
        httpResponseBody = getMethod("http://www.facebook.com/login.php");
    }
    logger.trace("Facebook: ========= get login page ResponseBody begin===========");
    logger.trace(httpResponseBody);
    logger.trace("Facebook: +++++++++ get login page ResponseBody end+++++++++");

    logger.trace("Facebook: Initial cookies: ");
    List<Cookie> cookies = getCookies();
    if (cookies.isEmpty()) {
        logger.trace("Facebook: None");
    } else {
        for (int i = 0; i < cookies.size(); i++) {
            logger.trace("Facebook: - " + cookies.get(i).toString());
        }
    }
    if(httpResponseBody == null){
        logger.warn("Facebook: Warning: Failed to get facebook login page.");
    }

    try
    {
        HttpPost httpost = new HttpPost("http://www.facebook.com/login.php");

        List <NameValuePair> nvps = new ArrayList <NameValuePair>();
        nvps.add(new BasicNameValuePair("email", email));
        nvps.add(new BasicNameValuePair("pass", pass));
        //don't know if is this necessary
        nvps.add(new BasicNameValuePair("login", ""));

        httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
        logger.info("Facebook: @executing post method to:" + "http://www.facebook.com/login.php");

        HttpResponse loginPostResponse = getHttpClient().execute(httpost);
        HttpEntity entity = loginPostResponse.getEntity();

        logger.trace("Facebook: Login form post: " + loginPostResponse.getStatusLine());
        if (entity != null) {
            logger.trace("Facebook: "+EntityUtils.toString(entity));
            entity.consumeContent();
        } else {
            logger.error("Facebook: Error: login post response entity is null");
            return FacebookErrorCode.kError_Login_GenericError;
        }

        logger.trace("Facebook: Post logon cookies:");
        cookies = getCookies();
        if (cookies.isEmpty()) {
            logger.trace("Facebook: None");
        } else {

                logger.trace("Facebook: - " + cookies.get(i).toString());
            }
        }

        int statusCode = loginPostResponse.getStatusLine().getStatusCode();

        logger.info("Facebook: Post Method done(" + statusCode + ")");



        switch(statusCode){
        case 100: break;//we should try again;
        case 301:

DefaultHttpClient httpclient = new DefaultHttpClient();

HttpGet httpget = new HttpGet("http://www.facebook.com/login.php");

HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();

System.out.println("Login form get: " + response.getStatusLine());
if (entity != null) {
    entity.consumeContent();
}
System.out.println("Initial set of cookies:");
List<Cookie> cookies = httpclient.getCookieStore().getCookies();
if (cookies.isEmpty()) {
    System.out.println("None");
} else {
    for (int i = 0; i < cookies.size(); i++) {
        System.out.println("- " + cookies.get(i).toString());
    }
}

HttpPost httpost = new HttpPost("http://www.facebook.com/login.php");

List <NameValuePair> nvps = new ArrayList <NameValuePair>();
nvps.add(new BasicNameValuePair("email", "******"));
nvps.add(new BasicNameValuePair("pass", "*******"));

httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));

response = httpclient.execute(httpost);
entity = response.getEntity();
System.out.println("Double check we've got right page " + EntityUtils.toString(entity));

System.out.println("Login form get: " + response.getStatusLine());
if (entity != null) {
    entity.consumeContent();
}

System.out.println("Post logon cookies:");
cookies = httpclient.getCookieStore().getCookies();
if (cookies.isEmpty()) {
    System.out.println("None");
} else {
    for (int i = 0; i < cookies.size(); i++) {
        System.out.println("- " + cookies.get(i).toString());
    }
}

httpclient.getConnectionManager().shutdown();

You have a look at HtmlUnit . It wraps HttpClient to create a mute Java browser with javaScript execution. Thus, you are not trying to constantly crack individual forms.
