Retrofit Demo

编写了一个最简单的Demo：

三种功能：

1、普通GET请求获取Ip地址与经纬度，返回JSon数据由Gson解析为对象；

2、带参数的GET请求根据经纬度定位周边基站，返回JSon数据由Gson解析List<Object>；

3、POST请求返回Json数据不用Gson解析，直接打印

Tips：

1、网络上的例子一般都是直接将Json数据转为对象，找了好久才知道可以用ResponseBody获取Json字符串 arg0.body().string()；

2、Post方法添加表单时要加@FormUrlEncoded，否则会报错 @Field parameters can only be used with formencoding. (parameter #1)

3、返回的JSon不是数组时不可以用List

ApiService:代码

RetrofitService ：三个网络请求接口

importjava.util.List;
import retrofit.Call;
import retrofit.http.Field;
import retrofit.http.FormUrlEncoded;
import retrofit.http.GET;
import retrofit.http.POST;
import retrofit.http.Path;
import retrofit.http.Query;
import bean.CellMode;
import bean.LocationMode;
import com.squareup.okhttp.ResponseBody;

public interface RetrofitService {
         //获取IP地址及定
         @POST("H_HDJAD_IP/servlet/IpLocationServlet")
         Call<LocationMode> getIpLoc();
         //反向基站定位
         @GET("/recell")
         Call<List<CellMode>>getcell(@Query("lat") String lat,@Query("lon") String lon);
         //上传基站信息
         @FormUrlEncoded
         @POST("/CellCollection/servlet/CellCollectionServlet")
         Call<ResponseBody>postCell(@Field("address") String address,@Field("result")String result);
}

RetrofitServiceGeter ：获取接口Interface

importjava.util.concurrent.TimeUnit;
import retrofit.GsonConverterFactory;
import retrofit.Retrofit;
import com.squareup.okhttp.OkHttpClient;
import config.ConstantsConfig;

public class RetrofitServiceGeter {
         static RetrofitServiceretrofitService =null;
         public static RetrofitServicegetRetrofitService(String url,boolean convert){
//                 if(retrofitService==null){
                            OkHttpClientclient = new OkHttpClient();
                            client.setConnectTimeout(ConstantsConfig.NET_CONNECT_TIME_OUT_TIME,TimeUnit.SECONDS);
                            client.setWriteTimeout(ConstantsConfig.NET_WRITE_TIME_OUT_TIME,TimeUnit.SECONDS);
                            client.setReadTimeout(ConstantsConfig.NET_READ_TIME_OUT_TIME,TimeUnit.SECONDS);
                            Retrofit.Builderbuilder = new Retrofit.Builder();
                            builder.client(client);
                            builder.baseUrl(url);
                            if(convert){
                                     builder.addConverterFactory(GsonConverterFactory.create());
                            }
                            Retrofitretrofit=builder.build();
                            retrofitService= retrofit.create(RetrofitService.class);
//                 }
                   return retrofitService;
         }
}

HttpUtil：网络请求代码
