I can't seem to figure out how to get android annotations rest client to work I'm having 2 main issues.

A)How to parse the generic json response and get the meaningful key

B)How to add parameters

For the first problem all responses come back as a json string fomatted like this

{"success":,"message":"","data":{}}

Where success is boolean message is a string and data is going to be the main data I want to parse that may be a boolean, an array, a string or an int

I'm pretty sure I need to intercept the response and handle the code but I'm not sure how to do that

Lets use a real response that look something like this

{"success":true,"message":"random message","data":{"profile":{"id":"44","user_id":"44","name":"Matt","username":"mitch","icon":"b1da7ae15027b7d6421c158d644f3220.png","med":"2a3df53fb39d1d8b5edbd0b93688fe4a.png","map":"b7bfed1f456ca4bc8ca748ba34ceeb47.png","background":null,"mobile_background":null}}

First in my interceptor I want to see if the boolean key "success" is true and then return the data value

@EBean
public class RestInterceptor implements ClientHttpRequestInterceptor {

    final String TAG = "rest";

    @Bean
    AuthStore authStore;

    @Override
    public ClientHttpResponse intercept(HttpRequest request, byte[] data, ClientHttpRequestExecution execution)
            throws IOException{

        //Need to set the api key here but nothing happens code quits
//        Log.d("Rest",authStore.getApiKey());

         HttpHeaders headers = request.getHeaders();

         headers.set("api_key","");

         ClientHttpResponse resp = execution.execute(request, data);

         HttpStatus code = resp.getStatusCode();


         if(code.value() == 200){
            Log.d(TAG,"success code 200"); 

            //valid http request but is it a valid API request?
                //perform some logic of if success == true in root json object
                //if true cast return data key 



         }
         else{
             Log.d(TAG,"fail code" + code.toString());
         }


         return resp;
    }

}

The second problem is sending params with the http request that have an api key and a session key, I define the application class like this

@EApplication
public class MyApp extends Application {

    final String TAG = "app";

    @Bean
    AuthStore authStore;

    @RestService
    RestClient restClient;


    public void onCreate() {
        super.onCreate();
        init();
    }

    @AfterInject
    public void init() {

        authStore.setApiKey("dummy_key");
        Log.d(TAG, "api key set to " + authStore.getApiKey());

    }
}

With the AuthStore class like this

@EBean(scope = Scope.Singleton)
public class AuthStore {

    public String apiKey,sessionKey;

    public String getApiKey() {
        return apiKey;
    }

    public void setApiKey(String apiKey) {
        this.apiKey = apiKey;
    }

    public String getSessionKey() {
        return sessionKey;
    }

    public void setSessionKey(String sessionKey) {
        this.sessionKey = sessionKey;
    }
}

Basically I'm setting a dummy api key at the application level in a singleton, which I should be able to access in the rest interceptor interface but the code just quits without errors I'm basically following this guide https://github.com/excilys/androidannotations/wiki/Authenticated-Rest-Client

Finally I have an activity class which injects the app dependency which has refrence to the rest http class and the authstore class

@EActivity(R.layout.activity_login)
public class LoginActivity extends Activity {

    @App
    MyApp app;
    @ViewById
    TextView email;
    @ViewById
    TextView password;
    @ViewById
    Button loginButton;


    @AfterInject
    public void init() {
        Log.d(app.TAG, "api in login key set to " + app.authStore.getApiKey());

    }

    @Click
    @Trace
    void loginButton() {

        login(email.toString(), password.toString());

    }

    @Background
    void login(String email, String password) {
         app.restClient.forceLogin();


    }
}

Sorry if it's a lot of info, I've been searching for a while and can't figure this out!

thanks in advance

あなたが使用しているライブラリ（注釈、春）についてはわかりませんが、 JSON にあるはずがないため、 success = true の解析に苦労しているようです。

JSON は、できればアプリの 1on1 のクラスを表す必要があるため、オブジェクトに簡単にマッピングできます。リクエストのステータスに関するアプリと Web サービス間の通信は、ヘッダーに入れる必要があります。

このように、JSON を解析する前に、リクエストのヘッダーを確認できます。

これは、JSON オブジェクトを再帰的に解析するために使用している方法です。

private void parseJson(JSONObject data) {

        if (data != null) {
            Iterator<String> it = data.keys();
            while (it.hasNext()) {
                String key = it.next();

                try {
                    if (data.get(key) instanceof JSONArray) {
                        JSONArray arry = data.getJSONArray(key);
                        int size = arry.length();
                        for (int i = 0; i < size; i++) {
                            parseJson(arry.getJSONObject(i));
                        }
                    } else if (data.get(key) instanceof JSONObject) {
                        parseJson(data.getJSONObject(key));
                    } else {
                        System.out.println("" + key + " : " + data.optString(key));
                    }
                } catch (Throwable e) {
                    System.out.println("" + key + " : " + data.optString(key));
                    e.printStackTrace();

                }
            }
        }
    }
