本文将介绍如何通过retrofit库post一串json格式的数32313133353236313431303231363533e78988e69d8331333363353861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

\* Height : 0

\* Speed : 0

\* Usedtime : 0

\*/

public List 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() \{

public double getSumDistance() \{

public void setSumDistance(double SumDistance) \{

public void setSetupTime(String SetupTime) \{

this.SetupTime = SetupTime;

public double getUsedTime() \{

public void setUsedTime(double UsedTime) \{

public List getPoints() \{

public void setPoints(List Points) \{

public static class PointsBean implements Parcelable \{

public void setId(String Id) \{

public String getRouteNo() \{

public void setRouteNo(String RouteNo) \{

public String getName() \{

public void setName(String Name) \{

public double getUsedtime() \{

return Usedtime;

public void setUsedtime(double Usedtime) \{

this.Usedtime = Usedtime;

@Override

public String toString() \{

return "PointsBean\{" +

"Id='" + Id + '\\'' +

", RouteNo='" + RouteNo + '\\'' +

'\}';

@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 CREATOR=new Creator() \{

@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 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 call=postRoute.postFlyRoute(body);

call.enqueue(new Callback() \{

@Override

public void onResponse(Call call, Response 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 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'
