首先我们在使用的时候需要根据接口返回的数据进行封装javabean对象，便于后面使用。
构建RetrofitService类进行传参和请求方式设置
package cn.hnshangyu.retrofitandrxjava.retrofit;
import java.util.List;
import java.util.Map;
import cn.hnshangyu.retrofitandrxjava.bean.BookResponse;
import cn.hnshangyu.retrofitandrxjava.bean.Parameters;

import okhttp3.MultipartBody;
import okhttp3.RequestBody;
import okhttp3.ResponseBody;
import retrofit2.Call;
import retrofit2.http.Body;
import retrofit2.http.Field;
import retrofit2.http.FieldMap;
import retrofit2.http.FormUrlEncoded;
import retrofit2.http.GET;
import retrofit2.http.Headers;
import retrofit2.http.Multipart;
import retrofit2.http.POST;
import retrofit2.http.Part;
import retrofit2.http.PartMap;
import retrofit2.http.Path;
import retrofit2.http.Query;
import retrofit2.http.QueryMap;
/**
* 每个接口都需要javaBean对象，需要生成
* Retrofit自动封装
*/
public interface RetrofitService {
/**

@GET("book/search")
Call getSearchBooks(@Query("q") String name,
@Query("tag") String tag, @Query("start") int start,
@Query("count") int count);
/**

@GET("book/search")
Call getSearchBooks(@QueryMap Map options);
/**

@GET("book/search")
Call getSearchBooks(@Query("q") List name);

Call getBook(@Path("id") String id);

Call postSearchBooks(@Field("book") String bookId, @Field("title") String title,
@Field("content") String content, @Field("rating") String rating);
/**

*
* @param fields
* @return
*/
@FormUrlEncoded
@POST("resource/information_list")
Call postSearchBooks(@FieldMap Map fields);
/**
* Post请求 @Body
*
* @param reviews
* @return 错误
* @Body parameters cannot be used with form or multi-part encoding. ???
*/
@POST("resource/information_list")
@Headers({"Content-Type: application/json;charset=UTF-8"})
Call postSearchBooks(@Body Parameters reviews);
/**
* 上传单个文件
*
* @param description
* @param file
* @return
*/
@Multipart
@POST("upload")
Call uploadFile(
@Part("description") RequestBody description,
@Part MultipartBody.Part file);
/**
* 上传多个文件方式一
*
* @param description
* @param file1
* @param file2
* @return
*/
@Multipart
@POST("UploadServlet")
Call uploadMultipleFiles(

/**

}
