Android: inicia sesión en el sitio web y conserva sesión / cookie mediante DefaultHttpClient

En una aplicación a la que tengo que iniciar sesión. Primero tengo que ejecutar un GET seguido de un POST y luego el GET de nuevo. El First get instanciará un ID de Jsession para mi conexión. El POST autenticará mi ID y luego el original obtendrá GET devolverá el contenido real.

El código siguiente es para una aplicación que se ejecuta en JBoss

 public boolean login() { HttpGet httpGet = new HttpGet( "http://localhost:8080/gwt-console-server/rs/identity/secure/sid/"); HttpPost httpPost = new HttpPost("http://localhost:8080/gwt-console-server/rs/identity/secure/j_security_check"); HttpResponse response = null; List<NameValuePair> nvps = new ArrayList<NameValuePair>(); nvps.add(new BasicNameValuePair(USER_FIELD, userName)); nvps.add(new BasicNameValuePair(PASS_FIELD, password)); try { httpPost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8)); response = httpClient.execute(httpGet); EntityUtils.consume(response.getEntity()); response = httpClient.execute(httpPost); EntityUtils.consume(response.getEntity()); response = httpClient.execute(httpGet); String sessionId =EntityUtils.toString(response.getEntity()); String cookieId =""; List<Cookie> cookies = ((AbstractHttpClient) httpClient).getCookieStore().getCookies(); for (Cookie cookie: cookies){ if (cookie.getName().equals("JSESSIONID")){ cookieId = cookie.getValue(); } } if(sessionId!= null && sessionId.equals(cookieId) ){ return true; } } catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return false; } 

Asumiendo que el objeto httpclient es el mismo en ambos casos, y suponiendo que RESTRICTED_URL está en el mismo dominio que LOGIN_URL , entonces creo que lo que tienes debería funcionar.

Es posible que desee utilizar Wireshark o un proxy o algo parecido para examinar las solicitudes HTTP que está realizando, para ver si la cookie está realmente conectada a la solicitud. Puede ser que la cookie está siendo adjunta, en cuyo caso hay algo más que está haciendo que la segunda solicitud de fallar.

Usted tiene que hacer DefaultHttpClient httpclient con patrón singleton para sessioncookie que todavía tiene sesión de sesión de inicio de sesión.

Esta es la clase Mainactivity :

 public static DefaultHttpClient httpClient; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); RequestPage request = new RequestPage(); request.post("http://www.example.com/login.php"); RequestPage requestProfile =new RequestPage(); requestProfile.post("http://www.example.com/profile.php"); } 

Y esta es la clase RequestPage :

 private InputStream post(String url){ String paramUsername = "username"; String paramPassword = "pass"; if(MainActivity.httpClient==null){ MainActivity.httpClient = new DefaultHttpClient(); } DefaultHttpClient httpClient = MainActivity.httpClient; // In a POST request, we don't pass the values in the URL. //Therefore we use only the web page URL as the parameter of the HttpPost argument HttpPost httpPost = new HttpPost(url); // Because we are not passing values over the URL, we should have a mechanism to pass the values that can be //uniquely separate by the other end. //To achieve that we use BasicNameValuePair //Things we need to pass with the POST request BasicNameValuePair usernameBasicNameValuePair = new BasicNameValuePair("username", paramUsername); BasicNameValuePair passwordBasicNameValuePAir = new BasicNameValuePair("password", paramPassword); // We add the content that we want to pass with the POST request to as name-value pairs //Now we put those sending details to an ArrayList with type safe of NameValuePair List<NameValuePair> nameValuePairList = new ArrayList<NameValuePair>(); nameValuePairList.add(usernameBasicNameValuePair); nameValuePairList.add(passwordBasicNameValuePAir); try { // UrlEncodedFormEntity is an entity composed of a list of url-encoded pairs. //This is typically useful while sending an HTTP POST request. UrlEncodedFormEntity urlEncodedFormEntity = new UrlEncodedFormEntity(nameValuePairList); // setEntity() hands the entity (here it is urlEncodedFormEntity) to the request. httpPost.setEntity(urlEncodedFormEntity); try { // HttpResponse is an interface just like HttpPost. //Therefore we can't initialize them HttpResponse httpResponse = httpClient.execute(httpPost); // According to the JAVA API, InputStream constructor do nothing. //So we can't initialize InputStream although it is not an interface return httpResponse.getEntity().getContent(); } catch (ClientProtocolException cpe) { System.out.println("First Exception caz of HttpResponese :" + cpe); cpe.printStackTrace(); } catch (IOException ioe) { System.out.println("Second Exception caz of HttpResponse :" + ioe); ioe.printStackTrace(); } } catch (UnsupportedEncodingException uee) { System.out.println("An Exception given because of UrlEncodedFormEntity argument :" + uee); uee.printStackTrace(); } return null; } 

Usted puede hacerlo de esta manera, aunque es más bien una solución.

 @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); WebView webv = (WebView)findViewById(R.id.MainActivity_webview); webv.setWebViewClient(new WebViewClient(){ @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } }); String postData = FIELD_NAME_LOGIN + "=" + LOGIN + "&" + FIELD_NAME_PASSWD + "=" + PASSWD; // this line logs you in and you stay logged in // I suppose it works this way because in this case WebView handles cookies itself webv.postUrl(URL, EncodingUtils.getBytes(postData, "utf-8")); }
