Série étrange de réponses du serveur après avoir obtenu une première réponse réussie

Question

Je reçois une première réponse réussie du serveur avec le bon code de statut et le résultat de données de json. Puis il y a 4 demandes successives sont déclenchées et elles gèlent toutes une mauvaise réponse (code d'état 400) avec un message Mauvaise demande. Ce comportement étrange se produit lorsque j'appuie sur une mise à jour, en essayant d'obtenir une liste de données du serveur. Voici mon code: La demande:

public static void loadMyOrders(Context context, final OrdersCallBack listener) { 
     KService kTestService = ApiUtils.getOrdersApiService(context); 
    // TODO to be changed to getMyOrders <Done> 
    KService.getAllTheOrders().enqueue(new Callback<List<OrderServer>>() { 
     @Override 
     public void onResponse(Call<List<OrderServer>> call, 
           Response<List<OrderServer>> response) { 
      if (response.code() == 400) { 
       try { 
        Log.d("Error code 400",response.errorBody().string()); 
       } catch (IOException e) { 
        e.printStackTrace(); 
        Log.d("IO exception"," " + e.getMessage()); 

       } 
      } 
      if (response.isSuccessful()) { 
       Log.d("listenerServerManager", response.code() + " "); 
       Log.d("slist0::" , " "+ response.body().toString()); 
       List<OrderServer> ordersList = response.body(); 
       for (OrderServer orderFromServer : ordersList) { 
        orderFromServer.compoundPrimaryKey(); 
       } 
       Log.d("slist1::" , " "+ ordersList.toString()); 
       listener.onSuccesful(ordersList); 
      } else { 
       Log.d("listenerServerManager", response.code() + " "); 
      listener.onError(response.code() + " "); 
      } 

     } 

     @Override 
     public void onFailure(Call<List<OrderServer>> call, Throwable t) { 
      Log.d("listenerServerManager", t.getMessage()+ " "); 
      listener.onError(t.getMessage() + " "); 

     } 
    }); 
} 

client rénovation:

public static Retrofit getClient(String baseUrl, Context context) { 
     sharedpreferences = context.getSharedPreferences(GlobalsManager.USERPREFERENCES, context.MODE_PRIVATE); 
       final String token = sharedpreferences.getString(GlobalsManager.TOKENKEY, " "); 
       Gson gson = new GsonBuilder().setExclusionStrategies(new ExclusionStrategy() { 
        @Override public boolean shouldSkipField(FieldAttributes f) { 
         return f.getDeclaringClass().equals(RealmObject.class); 
        } 
        @Override public boolean shouldSkipClass(Class<?> clazz) { 
         return false; 
        } 
       }).create(); 
       HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor(); 
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY); 
       if (httpClient == null) { 
        httpClient = new OkHttpClient.Builder().addNetworkInterceptor(new StethoInterceptor()); 
       } 
        httpClient.addInterceptor(new Interceptor() { 
         @Override public okhttp3.Response intercept(Chain chain) throws IOException { 
          Request request = chain.request() 
           .newBuilder() 
           .addHeader("Authorization", "Bearer " + token) 
           .addHeader("Cache-Control", "no-cache") 
           .addHeader("Content-Type", "application/json") 
           .build(); 
           return chain.proceed(request); 
         } 
        }); 
       httpClient.addInterceptor(loggingInterceptor); 
        //httpClient.retryOnConnectionFailure(true); 
        return new Retrofit.Builder().baseUrl(baseUrl) 
         .addConverterFactory(GsonConverterFactory.create(gson)) 
         .client(httpClient.build()) 
         .build(); 
       } 

C'est la sortie: la première réponse est réussie alors j'obtenir les 4 succesvies réponses avec 400 comme réponse de code.

Answer 1

Dans mon cas, le serveur était incapable de gérer ces demandes. Voyez si votre client HTTP est statique s'il enlève alors le statique de lui sinon il fera vos demandes existantes aussi avec de nouvelles demandes qui, à leur tour, rendront le serveur incapable de traiter toutes ces demandes en même temps. Voici ma configuration au cas où vous en auriez besoin.

public WebServiceInterface getNetworkService(@Nullable final String token, @NonNull final String url) throws IOException { 
     this.token = token; 
     this.url = url; 
     return getRetrofit(url).create(WebServiceInterface.class); 
    } 

    private Retrofit getRetrofit(String url) { 
     OkHttpClient.Builder client = 
       new OkHttpClient.Builder(). 
         addInterceptor(interceptor). 
         connectTimeout(90, TimeUnit.SECONDS). 
         writeTimeout(90, TimeUnit.SECONDS). 
         readTimeout(90, TimeUnit.SECONDS); 

     if (!Constant.RELEASE) { 
      client.addInterceptor(getLogger()); 
     } 

     retrofit.baseUrl(url) 
       .addConverterFactory(GsonConverterFactory.create()) 
       .addCallAdapterFactory(RxJavaCallAdapterFactory.create()) 
       .client(client.build()); 
     return retrofit.build(); 
    }
