改造：我怎樣才能得到令牌

我是一個新的程序員，我想用在改造Android的基於令牌的authorization.Therefore我也跟着教程（https://www.sitepoint.com/retrofit-a-simple-http-client-for-android-and-java/），它適用於我的rails服務器上的紅寶石（在教程這是一個PHP服務器）。但是我不知道令牌在程序中的保存位置或如何獲取。它只出現在Android控制檯中。我需要在我的android程序中解碼令牌。但令牌只出現在我的Android控制檯：改造：我怎樣才能得到令牌

com.example.programmingknowledge.login D/Retrofit: {"auth_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoxLCJuYW1lIjpudWxsLCJlbWFpbCI6ImV4YW1wbGVAbWFpbC5jb20iLCJleHAiOjE0NzMwMzU1MTF9.bhJABvEgtRISZVJ0DejjEtrGJyXzNV6PO0YGQ71xHRc"}

我怎樣才能得到我的android應用程序中的令牌？任何想法？

這是我的接口：

public interface Interface { 

     //This method is used for "POST" 
     @FormUrlEncoded 
     //@POST("/api.php") 
     @POST("/") 
     void postData(@Field("method") String method, 
         @Field("email") String username, 
         @Field("password") String password, 
         Callback<ServerResponse> serverResponseCallback); 

     //This method is used for "GET" 
     //@GET("/api.php") 
     @GET("/") 
     void getData(@Query("method") String method, 
        @Query("email") String username, 
        @Query("password") String password, 
        Callback<ServerResponse> serverResponseCallback); 

    }

這裏是從i中使用的通信的碼（更新與方法）：

import android.util.Log; 

import com.squareup.otto.Produce; 

import retrofit.Callback; 
import retrofit.RestAdapter; 
import retrofit.RetrofitError; 
import retrofit.client.Response; 


public class Communicator { 
    private static final String TAG = "Communicator"; 
    private static final String SERVER_URL = "http://10.0.2.2:3000/authenticate"; 

    public void loginPost(String email, String password){ 


     RestAdapter restAdapter = new RestAdapter.Builder() 
       .setEndpoint(SERVER_URL) 
       .setLogLevel(RestAdapter.LogLevel.FULL) 
       .build(); 
     Interface communicatorInterface = restAdapter.create(Interface.class); 

//HERE I PLACED THE METHOD, BUT HOW CAN I GET THE AUTH-TOKEN WITH THIS METHOD? I want to save it somewhere 
     communicatorInterface = ServiceGenerator.createService(Interface.class, "auth-token"); 




     Callback<ServerResponse> callback = new Callback<ServerResponse>() { 
      @Override 
      public void success(ServerResponse serverResponse, Response response2) { 
       if(serverResponse.getResponseCode() == 0){ 
        BusProvider.getInstance().post(produceServerEvent(serverResponse)); 
       }else{ 
        BusProvider.getInstance().post(produceErrorEvent(serverResponse.getResponseCode(), serverResponse.getMessage())); 
       } 

      } 

      @Override 
      public void failure(RetrofitError error) { 
       if(error != null){ 
        Log.e(TAG, error.getMessage()); 
        error.printStackTrace(); 
       } 
       BusProvider.getInstance().post(produceErrorEvent(-200,error.getMessage())); 
      } 
     }; 
     communicatorInterface.postData("login", email, password, callback); 

    } 


    public void loginGet(String email, String password){ 
     RestAdapter restAdapter = new RestAdapter.Builder() 
       .setEndpoint(SERVER_URL) 
       .setLogLevel(RestAdapter.LogLevel.FULL) 
       .build(); 
     Interface communicatorInterface = restAdapter.create(Interface.class); 
     Callback<ServerResponse> callback = new Callback<ServerResponse>() { 
      @Override 
      public void success(ServerResponse serverResponse, Response response2) { 
       if(serverResponse.getResponseCode() == 0){ 
        BusProvider.getInstance().post(produceServerEvent(serverResponse)); 
       }else{ 
        BusProvider.getInstance().post(produceErrorEvent(serverResponse.getResponseCode(), serverResponse.getMessage())); 
       } 
      } 

      @Override 
      public void failure(RetrofitError error) { 
       if(error != null){ 
        Log.e(TAG, error.getMessage()); 
        error.printStackTrace(); 
       } 
       BusProvider.getInstance().post(produceErrorEvent(-200,error.getMessage())); 
      } 
     }; 
     communicatorInterface.getData("login", email, password, callback); 

    } 

    @Produce 
    public ServerEvent produceServerEvent(ServerResponse serverResponse) { 
     return new ServerEvent(serverResponse); 
    } 

    @Produce 
    public ErrorEvent produceErrorEvent(int errorCode, String errorMsg) { 
     return new ErrorEvent(errorCode, errorMsg); 
    } 
}

這是我的ServiceGenerator類

public class ServiceGenerator { 

    public static final String API_BASE_URL = "https://your.api-base.url"; 

    private static RestAdapter.Builder builder = new RestAdapter.Builder() 
      .setEndpoint(API_BASE_URL) 
      .setClient(new OkClient(new OkHttpClient())); 

    public static <S> S createService(Class<S> serviceClass) { 
     return createService(serviceClass, null); 
    } 

    public static <S> S createService(Class<S> serviceClass, final String authToken) { 
     if (authToken != null) { 
      builder.setRequestInterceptor(new RequestInterceptor() { 
       @Override 
       public void intercept(RequestFacade request) { 
        request.addHeader("Authorization", authToken); 
       } 
      }); 
     } 

     RestAdapter adapter = builder.build(); 
     return adapter.create(serviceClass); 
    } 
}
