apache http客户端

Question

好的...为了在Android中以编程方式浏览网络。 我终于确信，Apache http api是必经之路。 我在使用它时需要一些帮助。 我已经设法使用httppost登录，但是之后我希望能够继续。 再次以facebook为例，我登录到facebook，现在我想使用此登录会话来说发布状态，我该如何进行？ 这是到目前为止的代码（需要清洁和填充，大部分是从各种来源复制的）

  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    DefaultHttpClient httpclient = new DefaultHttpClient();

    try {
        HttpGet httpget = new HttpGet("https://www.facebook.com/");
      try{
        HttpResponse response = httpclient.execute(httpget);
        HttpEntity entity = response.getEntity();

      //  System.out.println("Login form get: " + response.getStatusLine());
 //    EntityUtils.consume(entity);

       // 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());
            }
        }
       // https://www.facebook.com/login.php?login_attempt=1
         HttpPost httpost = new HttpPost("https://www.facebook.com/login.php?login_attempt=1");

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

        try {
            httpost.setEntity(new UrlEncodedFormEntity(nvps));
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        try {
            response = httpclient.execute(httpost);
        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        entity = response.getEntity();
        Toast.makeText(getBaseContext(), "done",Toast.LENGTH_LONG);
        System.out.println("Login form get: " + response.getStatusLine());
    //   EntityUtils.consume(entity);

        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());
            }
        }

    }finally {} }catch (Exception e) {
        // TODO: handle exception
    }finally {
        // When HttpClient instance is no longer needed,
        // shut down the connection manager to ensure
        // immediate deallocation of all system resources
        httpclient.getConnectionManager().shutdown();
        Toast.makeText(getBaseContext(), "done",Toast.LENGTH_LONG);
    }

} 
    }

用您的电子邮件和密码替换星号，这样您就可以进入Facebook，如何从那里发布状态？

再次请不要告诉我有一个Facebook API，我不想使用它，这里的重点是学习使用apache库

Answer 1

最好的开始方法是连线并查看发布状态时浏览器的运行状况。 然后在HTTPClient中适应它。

Answer 2

在Mobile Client中保持会话的最佳方法应该是使用OAuth。当您获得OAuth令牌时，可以使用该令牌来使用Facebook提供程序提供的任何api。
