Android如何通过Retrofit提交Json格式数据

时间:2022-07-27
本文章向大家介绍Android如何通过Retrofit提交Json格式数据，主要内容包括其使用实例、应用技巧、基本知识点总结和需要注意事项，具有一定的参考价值，需要的朋友可以参考一下。

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; 
/**

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

} 
}

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’
