Comment mettre l'identifiant de session de cookie dans la demande de volley?

Question

Donc, j'ai ce code pour faire une demande POST avec volley:

public class MainActivity extends AppCompatActivity {

 Button btnSearch;
 ProgressDialog loadingDialog;
 ListView lvResult;
 String session_id;
 RequestQueue queue;
 MyCookieManager myCookieManager;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  btnSearch = (Button) findViewById(R.id.btnSearch);
  lvResult = (ListView) findViewById(R.id.lvResult);
  loadingDialog = new ProgressDialog(MainActivity.this);
  loadingDialog.setMessage("Wait.\nLoading...");
  loadingDialog.setCancelable(false);
  myCookieManager = new MyCookieManager();

  requestCookie(); //FIRST CALL TO GET SESSION ID

  btnSearch.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View view) {
    showLoading();
    requestWithSomeHttpHeaders(); //CALL TO MAKE THE REQUEST WITH VALID SESSION ID
   }
  });

 }

 public void requestCookie() {
  queue = Volley.newRequestQueue(this);
  String url = "http://myurl.com/json/";

  StringRequest postRequest = new StringRequest(Request.Method.POST, url,
   new Response.Listener < String > () {
    @Override
    public void onResponse(String response) {
     //
     String x = myCookieManager.getCookieValue();
    }
   },
   new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
     Log.d("ERROR", "Error => " + error.toString());
     hideLoading();
    }
   }
  ) {
   @Override
   public byte[] getBody() throws AuthFailureError {
    String httpPostBody = "param1=XPTO&param2=XPTO";
    return httpPostBody.getBytes();
   }

   @Override
   public Map < String, String > getHeaders() throws AuthFailureError {
    Map <String, String> params = new HashMap < String, String > ();
    params.put("User-Agent", "Mozilla/5.0");
    params.put("Accept", "application/json, text/javascript, */*; q=0.01");
    params.put("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
    //params.put("Set-Cookie", session_id);// + " _ga=GA1.3.1300076726.1496455105; _gid=GA1.3.1624400465.1496455105; _gat=1; _gali=AguardeButton");
    //"PHPSESSID=ra0nbm0l22gsnl6s4jo0qkqci1");
    return params;
   }

   protected Response <String> parseNetworkResponse(NetworkResponse response) {
    try {
     String jsonString = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
     String header_response = String.valueOf(response.headers.values());
     int index1 = header_response.indexOf("PHPSESSID=");
     int index2 = header_response.indexOf("; path");
     //Log.e(Utils.tag, "error is : " + index1 + "::" + index2);
     session_id = header_response.substring(index1, index2);

     return Response.success(jsonString, HttpHeaderParser.parseCacheHeaders(response));
    } catch (UnsupportedEncodingException e) {
     return Response.error(new ParseError(e));
    }
   }
  };

  queue.add(postRequest);
 }

 public void requestWithSomeHttpHeaders() {
  queue = Volley.newRequestQueue(this);
  String url = "http://myurl.com/json/";

  StringRequest postRequest = new StringRequest(Request.Method.POST, url,
   new Response.Listener <String> () {
    @Override
    public void onResponse(String response) {
     Log.d("Response", response);
     String x = myCookieManager.getCookieValue();
     String status = "";

     try {
      JSONObject resultObject = new JSONObject(response);
      Log.d("JSON RESULT =>", resultObject.toString());
     } catch (JSONException e) {
      Toast.makeText(MainActivity.this, "Request Error", Toast.LENGTH_SHORT).show();
      e.printStackTrace();
     }

     hideLoading();
    }
   },
   new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
     Log.d("ERROR", "Error => " + error.toString());
     hideLoading();
    }
   }
  ) {
   @Override
   public byte[] getBody() throws AuthFailureError {
    String httpPostBody = "param1=XPTO&param2=XPTO";
    return httpPostBody.getBytes();
   }

   @Override
   public Map <String, String> getHeaders() throws AuthFailureError {
    Map <String, String> params = new HashMap <String, String> ();
    params.put("User-Agent", "Mozilla/5.0");
    params.put("Accept", "application/json, text/javascript, */*; q=0.01");
    params.put("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
    params.put("Cookie", /*myCookieManager.getCookieValue()*/ session_id + "; _ga=GA1.3.1300076726.1496455105; _gid=GA1.3.1624400465.1496455105; _gat=1; _gali=AguardeButton");
    return params;
   }
  };

  queue.add(postRequest);
 }

 private void showLoading() {
  runOnUiThread(new Runnable() {
   @Override
   public void run() {
    if (!loadingDialog.isShowing())
     loadingDialog.show();
   }
  });
 }

 private void hideLoading() {
  runOnUiThread(new Runnable() {
   @Override
   public void run() {
    if (loadingDialog.isShowing())
     loadingDialog.dismiss();
   }
  });
 }
}

Si j'envoie un ID de cookie valide, cela retourne un objet JSON valide, sinon un objet vide.

J'ai essayé (sans succès) de définir des poignées de cookie par défaut comme

CookieManager manager = new CookieManager(); CookieHandler.setDefault(manager);

mais je reçois un objet vide.

Comment mettre un identifiant de session de cookie valide pour poster une demande?

Answer 1

Le problème était donc d'obtenir un cookie valide. Mon erreur a été de l'obtenir à partir de la requête POST elle-même. J'ai conservé le même principe de fonctionnement: obtenir le cookie au démarrage de l'application, mais utiliser GET au lieu de POST et appeler la racine de l'URL au lieu de l'adresse où j'ai obtenu le JSON.

Ma solution ressemblait à ceci:

public void requestCookie() {
  queue = Volley.newRequestQueue(this);
  String url = "http://myurl.com/";

  StringRequest getRequest = new StringRequest(Request.Method.GET, url,
   new Response.Listener <String> () {
    @Override
    public void onResponse(String response) {
     String x = myCookieManager.getCookieValue();
    }
   },
   new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
     Log.d("ERROR", "Error => " + error.toString());
     hideLoading();
    }
   }
  ) {   
   protected Response <String> parseNetworkResponse(NetworkResponse response) {
    try {
     String jsonString = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
     String header_response = String.valueOf(response.headers.values());
     int index1 = header_response.indexOf("PHPSESSID=");
     int index2 = header_response.indexOf("; path");
     //Log.e(Utils.tag, "error is : " + index1 + "::" + index2);
     session_id = header_response.substring(index1, index2);

     return Response.success(jsonString, HttpHeaderParser.parseCacheHeaders(response));
    } catch (UnsupportedEncodingException e) {
     return Response.error(new ParseError(e));
    }
   }
  };

  queue.add(getRequest);
 }

Utilisation de cookies avec la bibliothèque de volley Android

Classe de demande:

public class StringRequest extends com.Android.volley.toolbox.StringRequest {

    private final Map<String, String> _params;

    /**

    public StringRequest(int method, String url, Map<String, String> params, Listener<String> listener,
            ErrorListener errorListener) {

        _params = params;
    }

    @Override
    protected Map<String, String> getParams() {

    }

    /* (non-Javadoc)

    @Override
    protected Response<String> parseNetworkResponse(NetworkResponse response) {
        // since we don't know which of the two underlying network vehicles
        // will Volley use, we have to handle and store session cookies manually
        MyApp.get().checkSessionCookie(response.headers);

        return super.parseNetworkResponse(response);

        }

        MyApp.get().addSessionCookie(headers);

        return headers;
    }
}

MyApp:

public class MyApp extends Application {
    private static final String SET_COOKIE_KEY = "Set-Cookie";
    private static final String COOKIE_KEY = "Cookie";
    private static final String SESSION_COOKIE = "sessionid";

                    Editor prefEditor = _preferences.edit();
                    prefEditor.putString(SESSION_COOKIE, cookie);
                    prefEditor.commit();
                }
            }
    }

    /**

        if (sessionId.length() > 0) {
            StringBuilder builder = new StringBuilder();
            builder.append(SESSION_COOKIE);
            builder.append("=");

            headers.put(COOKIE_KEY, builder.toString());
        }
    }

}

Answer 3

Vous obtenez un cookie (ID de session) dans la réponse de connexion, enregistrez un cookie dans la préférence partagée ou une autre base de données, et utilisez-le pour envoyer une demande.

pour obtenir un cookie à partir d'une demande de connexion

 CustomStringRequest stringRequest = new CustomStringRequest(Request.Method.POST, SIGN_IN_URL,
                    new Response.Listener<CustomStringRequest.ResponseM>() {
                        @Override
                        public void onResponse(CustomStringRequest.ResponseM result) {

                            CookieManager cookieManage = new CookieManager();
                            CookieHandler.setDefault(cookieManage);

                            progressDialog.hide();
                            try {
                                //From here you will get headers
                                String sessionId = result.headers.get("Set-Cookie");
                                String responseString = result.response;

                                Log.e("session", sessionId);
                                Log.e("responseString", responseString);

                                JSONObject object = new JSONObject(responseString);

Classe CustomStringRequest 

public class CustomStringRequest extends Request<CustomStringRequest.ResponseM> {


    private Response.Listener<CustomStringRequest.ResponseM> mListener;

    public CustomStringRequest(int method, String url, Response.Listener<CustomStringRequest.ResponseM> responseListener, Response.ErrorListener listener) {
        super(method, url, listener);
        this.mListener = responseListener;
    }


    @Override
    protected void deliverResponse(ResponseM response) {
        this.mListener.onResponse(response);
    }

    @Override
    protected Response<ResponseM> parseNetworkResponse(NetworkResponse response) {
        String parsed;
        try {
            parsed = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
        } catch (UnsupportedEncodingException e) {
            parsed = new String(response.data);
        }

        ResponseM responseM = new ResponseM();
        responseM.headers = response.headers;
        responseM.response = parsed;

        return Response.success(responseM, HttpHeaderParser.parseCacheHeaders(response));
    }


    public static class ResponseM {
        public Map<String, String> headers;
        public String response;
    }

}

définir un cookie lorsque vous ajoutez une demande au serveur ..

                @Override
                public Map<String, String> getHeaders() throws AuthFailureError {
                    Map<String, String> headers = new HashMap<String, String>();

                    String session=sharedPreferences.getString("sessionId","");
                    headers.put("Cookie",session);
                    return headers;
                }
