Данные не получены с веб-серверов

/ 04 июля 2019

Я пытался создать приложение, которое получит данные об этимологии из приложения оксфордского словаря.При попытке использовать модификацию для получения данных всегда вызывается onFailiure ().Я буду загружать свой код, а также правильный код, но тот, который вместо ссылки использует HttpsURLConnection.

Я подумал, что app_key и app_id не отправляются на сервер должным образом, поэтому я попытался отправить их вРазличные пути.Первый способ добавить тег @Headers 

@Headers({"Accept: application/json","app_id: ********","app_key: ******************"})

Я также попытался перехватить, чтобы добавить заголовок. 

@Override
    public Response intercept(Interceptor.Chain chain) throws IOException {
        Request request = chain.request();
        Request newRequest;

        newRequest = request.newBuilder()
                .addHeader(Accept,"application/json").addHeader(app_id,"*******").addHeader(app_key,"**********")
                .build();
        return chain.proceed(newRequest);
    }

, а затем добавить клиента для модернизации.

Но всеони возвращали ту же ошибку.

Вот мой код, использующий модификацию.

MainActivity.java 

public class MainActivity extends AppCompatActivity {

    GetDataInterface INTERFACE;
    WordDetails wordclass;
    TextView temp;
    final String app_id = "*********";
    final String app_key = "***************";
    final String theword = "chaos";
    final String word_id = theword.toLowerCase();
    final String TheAdd = "https://od-api.oxforddictionaries.com:443/api/v2/entries/en-gb/";

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

        temp = (TextView)findViewById(R.id.temp);
        wordclass = new WordDetails();

        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("https://od-api.oxforddictionaries.com:443/api/v2/entries/en-gb/")
                .addConverterFactory(GsonConverterFactory.create())
                .build();

        INTERFACE = retrofit.create(GetDataInterface.class);
        Call<WordDetails> call = INTERFACE.getData(word_id,"etymologies","false");

        call.enqueue(new Callback<WordDetails>() {
            @Override
            public void onResponse(Call<WordDetails> call, Response<WordDetails> response) {
                if(!response.isSuccessful())
                {
                    System.out.println("Server Error.");
                    return;
                }
                wordclass = new WordDetails();
                wordclass=response.body();

                if(wordclass.getResults().getLexicalEntries().getEntries().getEtymologies()!=null)
                {
                    temp.setText(wordclass.getResults().getLexicalEntries().getEntries().getEtymologies());
                }
                else
                    temp.setText("ERROR");
            }
            @Override
            public void onFailure(Call<WordDetails> call, Throwable t) {
                System.out.println("Failed to fetch.");
            }
        });
    }

Теперь тот, который использует HttpsURLConnection и который работает хорошо.(для справки, чтобы помочь мне с кодом дооснащения) 

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

    TEMP = (TextView) findViewById(R.id.TEMP);

    new CallbackTask().execute(dictionaryEntries());
}

private String dictionaryEntries() {
    final String language = "en-gb";
    final String word = "chaos";
    final String fields = "etymologies";
    final String strictMatch = "false";
    final String word_id = word.toLowerCase();
    return "https://od-api.oxforddictionaries.com:443/api/v2/entries/" + language + "/" + word_id + "?" + "fields=" + fields + "&strictMatch=" + strictMatch;
}


private class CallbackTask extends AsyncTask<String, Integer, String> {

    @Override
    protected String doInBackground(String... params) {

        final String app_id = "********";
        final String app_key = "******************";
        try {
            URL url = new URL(params[0]);
            HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
            urlConnection.setRequestProperty("Accept","application/json");
            urlConnection.setRequestProperty("app_id",app_id);
            urlConnection.setRequestProperty("app_key",app_key);

            // read the output from the server
            BufferedReader reader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
            StringBuilder stringBuilder = new StringBuilder();

            String line = null;
            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line + "\n");
            }

            return stringBuilder.toString();

        }
        catch (Exception e) {
            e.printStackTrace();
            return e.toString();
        }
    }

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);

        TEMP.setText(result);
    }
}

Выходные данные для этого приложения выглядят примерно так: https://ibb.co/0FCtG21

Я хотел бы получить данные (этимология)хаоса), который будет отображаться в текстовом представлении с использованием модернизации.HttpsURLConnection для справки показывает природу оксфордского API.

Как оказалось, мой WordDetails.class был не прав. Все переменные должны были быть в форме списка. 

public class WordDetails {
    List<Results> results;

    public List<Results> getResults()
    {
        return results;
    }

    class Results
    {
        List<Lexical> lexicalEntries;
        public List<Lexical> getLexicalEntries() {
            return lexicalEntries;
        }

        class Lexical
        {
            List<Entries> entries;
            public List<Entries> getEntries() {
                return entries;
            }

            class Entries
            {
                List<String> etymologies;
                public List<String> getEtymologies() {
                    return etymologies;
                }
            }
        }
    }
}
...
