如何通过Retrofit提交Json格式数据

Answer 1

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，

[java] view plain copy
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;
/**
* Id : string
* RouteNo : string
* Name : string
* Longitude : string
* Latitude : string
* Height : 0
* Distance : 0
* Yaw : 0
* Pitch : 0
* Speed : 0
* Usedtime : 0
*/

public List<PointsBean> Points;

public String getId() {
return Id;
}

public void setId(String Id) {
this.Id = Id;
}

public String getDeviceId() {
return DeviceId;
}

public void setDeviceId(String DeviceId) {
this.DeviceId = DeviceId;
}

public String getName() {
return Name;
}

public void setName(String Name) {
this.Name = Name;
}

public double getSumDistance() {
return SumDistance;
}

public void setSumDistance(double SumDistance) {
this.SumDistance = SumDistance;
}

public String getRouteNo() {
return RouteNo;
}

public void setRouteNo(String RouteNo) {
this.RouteNo = RouteNo;
}

public int getSumPoints() {
return SumPoints;
}

public void setSumPoints(int SumPoints) {
this.SumPoints = SumPoints;
}

public String getSetupTime() {
return SetupTime;
}

public void setSetupTime(String SetupTime) {
this.SetupTime = SetupTime;
}

public double getUsedTime() {
return UsedTime;
}

public void setUsedTime(double UsedTime) {
this.UsedTime = UsedTime;
}

public List<PointsBean> getPoints() {
return Points;
}

public void setPoints(List<PointsBean> Points) {
this.Points = Points;
}

public static class PointsBean implements Parcelable {
public String Id;
public String RouteNo;
public String Name;
public String Longitude;
public String Latitude;
public double Height;
public double Distance;
public double Yaw;
public double Pitch;
public double Speed;
public double Usedtime;

public String getId() {
return Id;
}

public void setId(String Id) {
this.Id = Id;
}

public String getRouteNo() {
return RouteNo;
}

public void setRouteNo(String RouteNo) {
this.RouteNo = RouteNo;
}

public String getName() {
return Name;
}

public void setName(String Name) {
this.Name = Name;
}

public String getLongitude() {
return Longitude;
}

public void setLongitude(String Longitude) {
this.Longitude = Longitude;
}

public String getLatitude() {
return Latitude;
}

public void setLatitude(String Latitude) {
this.Latitude = Latitude;
}

public double getHeight() {
return Height;
}

public void setHeight(double Height) {
this.Height = Height;
}

public double getDistance() {
return Distance;
}

public void setDistance(double Distance) {
this.Distance = Distance;
}

public double getYaw() {
return Yaw;
}

public void setYaw(double Yaw) {
this.Yaw = Yaw;
}

public double getPitch() {
return Pitch;
}

public void setPitch(double Pitch) {
this.Pitch = Pitch;
}

public double getSpeed() {
return Speed;
}

public void setSpeed(double Speed) {
this.Speed = Speed;
}

public double getUsedtime() {
return Usedtime;
}

public void setUsedtime(double Usedtime) {
this.Usedtime = Usedtime;
}

@Override
public String toString() {
return "PointsBean{" +
"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);
dest.writeString(Longitude);
dest.writeString(Latitude);
dest.writeDouble(Height);
dest.writeDouble(Distance);
dest.writeDouble(Yaw);
dest.writeDouble(Pitch);
dest.writeDouble(Speed);
dest.writeDouble(Usedtime);
}
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());
return pointsBean;
}

@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 + '\'' +
", DeviceId='" + DeviceId + '\'' +
", Name='" + Name + '\'' +
", SumDistance=" + SumDistance +
", RouteNo='" + RouteNo + '\'' +
", SumPoints=" + SumPoints +
", SetupTime='" + SetupTime + '\'' +
", UsedTime=" + UsedTime +
", Points=" + Points +
'}';
}

}
然后就来建立接口了，其内容如下：
[java] view plain copy
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：
[java] view plain copy
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
[java] view plain copy
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());
}
});
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'
