Android 如何通过Retrofit提交Json格式数据

本文将介绍如何通过retrofit库post一串json格式的数据。首先post的json数据格式如下：

{
  "Id": "string",
  "DeviceId": "string",
  "Name": "string",
  "SumDistance": ,
  "RouteNo": "string",
  "SumPoints": ,
  "SetupTime": "2016-06-10T13:11:00.766Z",
  "UsedTime": ,
  "Points": [
    {
      "Id": "string",
      "RouteNo": "string",
      "Name": "string",
      "Longitude": "string",
      "Latitude": "string",
      "Height": ,
      "Distance": ,
      "Yaw": ,
      "Pitch": ,
      "Speed": ,
      "Usedtime":
    }
  ]
}

通过安装android studio gsonformat插件，根据上面的json格式自动生成一个Bean类，本文命名为FlyRouteBean

package com.example.administrator.retrofitex;
import java.util.List;

import android.os.Parcel;
import android.os.Parcelable;

/**
 * Created by Administrator on 2016/6/10.
 */
public class FlyRouteBean{

    /**
     * Id : string
     * DeviceId : string
     * Name : string
     * SumDistance : 0
     * RouteNo : string
     * SumPoints : 0
     * SetupTime : 2016-05-23T06:20:50.254Z
     * UsedTime : 0
     * Points : [{"Id":"string","RouteNo":"string","Name":"string","Longitude":"string","Latitude":"string","Height":0,"Distance":0,"Yaw":0,"Pitch":0,"Speed":0,"Usedtime":0}]
     */

            @Override
            public PointsBean createFromParcel(Parcel source) {
                // TODO Auto-generated method stub
                PointsBean pointsBean=new PointsBean();
                pointsBean.setId(source.readString());
                pointsBean.setRouteNo(source.readString());
                pointsBean.setName(source.readString());
                pointsBean.setLongitude(source.readString());
                pointsBean.setLatitude(source.readString());
                pointsBean.setHeight(source.readInt());
                pointsBean.setDistance(source.readInt());
                pointsBean.setYaw(source.readInt());
                pointsBean.setPitch(source.readInt());

                return pointsBean;
            }

            @Override
            public PointsBean[] newArray(int size) {
                // TODO Auto-generated method stub
                return new PointsBean[size];
            }

        };

        @Override
        public int describeContents() {

            return ;
        }
    }

    @Override
    public String toString() {
        return "FlyRouteBean{" +
                "Id='" + Id + '\'' +
                ", DeviceId='" + DeviceId + '\'' +
                ", Name='" + Name + '\'' +

                ", Points=" + Points +
                '}';
    }

}

然后就来建立接口了，其内容如下：

public interface PostRoute {
   @Headers({"Content-Type: application/json","Accept: application/json"})//需要添加头
    @POST("api/FlyRoute/Add")
   Call<FlyRouteBean> postFlyRoute(@Body RequestBody route);//传入的参数为RequestBody
}

接下来就是提交数据的了：

        FlyRouteBean flyRouteBean=new FlyRouteBean();
        flyRouteBean=initdata(flyRouteBean);//根据Bean类初始化一个需要提交的数据类
        Gson gson=new Gson();
        String route= gson.toJson(flyRouteBean);//通过Gson将Bean转化为Json字符串形式  

        Retrofit retrofit=new Retrofit.Builder()
                .baseUrl(URL)
                .addConverterFactory( GsonConverterFactory.create())
                .build();
        PostRoute postRoute=retrofit.create(PostRoute.class);
        RequestBody body=RequestBody.create(okhttp3.MediaType.parse("application/json; charset=utf-8"),route);
        Call<FlyRouteBean> call=postRoute.postFlyRoute(body);
       call.enqueue(new Callback<FlyRouteBean>() {
        @Override
        public void onResponse(Call<FlyRouteBean> call, Response<FlyRouteBean> response) {
            Log.e("sssss","-----------------------"+response.body().getDeviceId());//这里是用于测试，服务器返回的数据就是提交的数据。
        }

        @Override
        public void onFailure(Call<FlyRouteBean> call, Throwable t) {
            Log.e("sssss",t.getMessage());
        }
    });

<----------------------- 更新如何同时提交json数据和其他查询字段：------------------------------>

服务器端(ASP)：核心代码如下，接收一个json格式学生类，加一个bool类型

[HttpPost]
    public IHttpActionResult Info(Student stu, bool IsGay)
        {
            
            return Ok(stu.Name);
        }

客户端：

//接口地址：http://172.20.69.209:9665/api/Test/Info?IsGay={IsGay}
@POST("api/Test/Info")
Call<ResponseBody> postStudent(@Body RequestBody stu,@Query("IsGay") boolean IsGay);

实现代码:

Student stu=new Student();
stu.setId("20103177");
stu.setName("zpm");
stu.setAge(18);
Gson gson=new Gson();
String route= gson.toJson(stu);
Log.e("post", "//");

Retrofit retrofit=new Retrofit.Builder()
        .baseUrl("http://172.20.69.209:9665/")
        .addConverterFactory( GsonConverterFactory.create())
        .build();
PostRoute postRoute=retrofit.create(PostRoute.class);
RequestBody body=RequestBody.create(okhttp3.MediaType.parse("application/json; charset=utf-8"),route);
Call<ResponseBody> call=postRoute.postStudent(body,true);
call.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
        try {
            Log.i("onResponse", response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onFailure(Call<ResponseBody> call, Throwable t) {
        Log.e("onFailure", t.getMessage());
    }
});

Log.e("postjson", route);

结果：

具体代码已经传到github

PS：本文中服务器都是楼主在局域网搭建的，

需要添加的依赖：

compile 'com.squareup.retrofit2:retrofit:2.0.2'
    compile 'com.squareup.retrofit2:converter-gson:2.0.0-beta3'
