如何通过Retrofit提交Json格式数据

Answer 1

直接上个实例吧。
通过retrofit库post一串json格式的数据。首先post的json数据格式如下：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25

{
"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，

2
3
4
5
6
7

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：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22

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());
}
});
