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": 0,
 "RouteNo": "string",
 "SumPoints": 0,
 "SetupTime": "2016-06-10T13:11:00.766Z",
 "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
  }
 ]
}

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}]
   */ 

  public String Id;
  public String DeviceId;
  public String Name;
  public double SumDistance;
  public String RouteNo;
  public int SumPoints;
  public String SetupTime;
  public double UsedTime;
  /**

   * Pitch : 0
   * Speed : 0
   * Usedtime : 0

  public List<PointsBean> getPoints() {

          "Id='" + Id + '\'' +
          ", RouteNo='" + RouteNo + '\'' +
          ", Name='" + Name + '\'' +
          ", Longitude='" + Longitude + '\'' +
          ", Latitude='" + Latitude + '\'' +
          ", Height=" + Height +
          ", Distance=" + Distance +
          ", Yaw=" + Yaw +
          ", Pitch=" + Pitch +
          ", Speed=" + Speed +
          ", Usedtime=" + Usedtime +
          '}';
    } 

    @Override
    public void writeToParcel(Parcel dest, int flags) {
      // TODO Auto-generated method stub
      dest.writeString(Id);
      dest.writeString(RouteNo);
      dest.writeString(Name);

    }
    public static final Creator<PointsBean> CREATOR=new Creator<PointsBean>() { 

      @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());
        pointsBean.setSpeed(source.readInt());
        pointsBean.setUsedtime(source.readInt());

      } 

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

    }; 

    @Override
    public int describeContents() {
      // TODO Auto-generated method stub
      return 0;
    }
  } 

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

        ", UsedTime=" + UsedTime +
        ", 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'
