Android如何通过Retrofit提交Json格式数据

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}] 
   */

   * speed : 0 
   * usedtime : 0

        pointsbean pointsbean=new pointsbean(); 
        pointsbean.setid(source.readstring());

        ", points=" + points + 
        '}'; 
  } 
 
   
} 

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'
