Question

我使用Retrofit来集成Web服务，当我运行我的app控制器进入Retrofit成功块时，但我如何在Json string formate中打印ResponseBody

请一位有人帮助我

import android.support.v7.app.AppCompatActivity;
import java.util.concurrent.TimeUnit;
import okhttp3.OkHttpClient;
import okhttp3.logging.HttpLoggingInterceptor;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;

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

                Retrofit retrofit = new Retrofit.Builder().baseUrl(url).
                        addConverterFactory(GsonConverterFactory.create()).build();

                RetrofitGetAPI service = retrofit.create(RetrofitGetAPI.class);

                retrofit.Call<List<CardTypes>> call = service.getProfileData();

                call.enqueue(new Callback<List<CardTypes>>() {
                    @Override
                    public void onResponse(Response<List<CardTypes>> response, Retrofit retrofit) {
                        System.out.println("Response is=====>" + response.body());
                    }

                    @Override
                    public void onFailure(Throwable t) {
                        System.out.println("Failure response is====>");
                    }
                });
            }

RetrofitGetAPI： - ------------

  public interface RetrofitGetAPI {

    @GET("api/RetrofitProfileResponse")
    Call<List<CardTypes>> getProfileData();
}

CardTypes： -

public class CardTypes {

    private int paymenttypeid;
    private String cardType;

    public String getCardType() {
        return cardType;
    }

    public void setCardType(String cardType) {
        this.cardType = cardType;
    }

    public int getPaymenttypeid() {
        return paymenttypeid;
    }

    public void setPaymenttypeid(int paymenttypeid) {
        this.paymenttypeid = paymenttypeid;
    }

}

服务器响应： -

   [
  {
    "paymenttypeid": 1,
    "cardType": "Master Card"
  },
  {
    "paymenttypeid": 2,
    "cardType": "VISA"
  }
]

尝试启用日志记录模式，您将能够看到响应，这就是它的完成方式，

app gradle

compile 'com.squareup.retrofit2:retrofit:2.1.0'
compile 'com.squareup.retrofit2:converter-gson:2.1.0'    
compile 'com.squareup.okhttp3:logging-interceptor:3.3.1'

构建这样的改造客户端，

import okhttp3.OkHttpClient;
import okhttp3.logging.HttpLoggingInterceptor;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;

            HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
            // set your desired log level
            logging.setLevel(HttpLoggingInterceptor.Level.BODY);

            final OkHttpClient okHttpClient = new OkHttpClient.Builder()
                        .readTimeout(30, TimeUnit.SECONDS)
                        .connectTimeout(30, TimeUnit.SECONDS)
                        .addInterceptor(logging)
                        .build();

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

Answer 2

您是否使用邮递员或其他API拦截器测试了您的API并检查了响应是什么？

如果您的api给出了正确答案，那么response.body()会在这种情况下为您提供一个List对象，即您 CardTypes列表。您需要将其转换为字符串，以便以适当的格式打印。您可以使用new Gson().toJson(object)将对象转换为String。
