本文將介紹如何通過retrofit庫post一串json格式的數據。首先post的json數據格式如下：

{ "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  } ]}

通過安裝Android studio gsonformat插件，根據上面的json格式自動生成一個Bean類，本文命名為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;   /**    * 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 +         '}';   }     }

然后就來建立接口了，其內容如下：

public interface PostRoute {   @Headers({"Content-Type: application/json","Accept: application/json"})//需要添加頭   @POST("api/FlyRoute/Add")   Call<FlyRouteBean> postFlyRoute(@Body RequestBody route);//傳入的參數為RequestBody }

接下來就是提交數據的了：

FlyRouteBean flyRouteBean=new FlyRouteBean(); flyRouteBean=initdata(flyRouteBean);//根據Bean類初始化一個需要提交的數據類 Gson gson=new Gson(); String route= gson.toJson(flyRouteBean);//通過Gson將Bean轉化為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());//這里是用于測試，服務器返回的數據就是提交的數據。   }    @Override   public void onFailure(Call<FlyRouteBean> call, Throwable t) {     Log.e("sssss",t.getMessage());   } });

<----------- 更新如何同時提交json數據和其他查詢字段：--------------->

服務器端(ASP)：核心代碼如下，接收一個json格式學生類，加一個bool類型

 [HttpPost]  public IHttpActionResult Info(Student stu, bool IsGay)    {            return Ok(stu.Name);    }

客戶端：

//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);

實現代碼:

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", "http://");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);

結果：
