java.io.EOFException: Ende der Eingabe in Zeile 1 Spalte 1

Question

Meine Retrofit sollte eine Liste von Lesezeichen erhalten, und alles hat funktioniert, während ich WAMP Server verwendet habe. Wenn ich Server auf externe geändert (sonst nichts geändert, nur die IP-Adresse des Servers und Abrufen von alles andere funktioniert) habe ich einen Fehler:

Mein Retrofit-Code:

public void init() { 
     OkHttpClient.Builder okHttpClient = new OkHttpClient.Builder(); 

     HttpLoggingInterceptor debugger = 
       new HttpLoggingInterceptor() 
         .setLevel(HttpLoggingInterceptor.Level.BODY); 
     okHttpClient 
       .addInterceptor(debugger); 

     Retrofit retrofit = new Retrofit.Builder() 
       .baseUrl(Constants.BASE_URL) 
       .addConverterFactory(GsonConverterFactory.create()) 
       .client(okHttpClient.build()) 
       .build(); 

     RequestInterface requestInterface = retrofit.create(RequestInterface.class); 

     String email = pref.getString(Constants.EMAIL, ""); 
     System.out.println(email); 
     String id_group = pref.getString(Constants.ID_GROUP, ""); 
     System.out.println(id_group); 
     String nazwa = pref.getString(Constants.NAZWA, ""); 

     Integer id_int_group = Integer.parseInt(id_group); 
     Bookmark bookmark = new Bookmark(email, id_int_group, nazwa); 

     ServerRequest request2 = new ServerRequest(); 
     request2.setOperation(Constants.GET_MY_GROUPS); 
     request2.setBookmark(bookmark); 

     Call<List<Bookmark>> response2 = requestInterface.operation2(request2); 

     response2.enqueue(new Callback<List<Bookmark>>() { 

      @Override 
      public void onResponse(Call<List<Bookmark>> call, retrofit2.Response<List<Bookmark>> response2) { 
       listOfBookmarks = response2.body(); 
       bookmarkToString(); 
       simpleAdapter.notifyDataSetChanged(); // refresh listivew 
      } 

      @Override 
      public void onFailure(Call<List<Bookmark>> call, Throwable t) { 

       Log.d(Constants.TAG, "Nie zaladowano!", t); 

      } 
     }); 
    }

Answer 1

Wenn Sie sehen,

java.io.EOFException: End of input at line 1 column 1

es zeigt ein Problem mit dem Parsen etwas an. Es erwartet etwas Text zu analysieren, aber es hat Ende der Datei (EOF).

Dann sagte man: auf jeden Fall nicht auf dem Code

When I changed server to external (nothing else changed)

Wenn dies vorher gearbeitet, Ihr Problem ist, und es ist auf den Daten, die Sie abrufen. Ihr neuer Server weist entweder Ihre Anfragen zurück oder gibt leere Daten zurück. Versuchen Sie, dieselbe Anfrage manuell (über postman oder einen anderen API-Client) zu machen und sehen Sie, wie die Antwort lautet. Es wird sehr wahrscheinlich sagen, wo der Fehler ist.
