也可以直接提交okhttp的requestbody
public interface Service {
@Headers("Content-Type:application/json")
@POST("/artbean/api/api1/Home/Life/LifeNewsID")
Call postBody(@Body RequestBody body);
@Headers("Content-Type:application/json")
@POST("/artbean/api/api1/Home/Address/editAddress")
Call editAddress(@Body RequestBody body);
@GET("/artbean/api/api1/home/conlist/index")
Call getApiList();
}
