可以参考这2篇文章：

公司年会抽奖的:

接口：获取服务器的状态（用于判断是否可以开始抽奖）
url:
http://192.168.16.105:8080/getServerStatus
method: Get
success: {"id":1,"start":0,"code":3}
error: {"code":-1,"error":"失败原因"}
id： 可以不用管
start: start=1时可以开始抽奖，为0时不能抽奖
code : 这个代表是第几轮抽奖

接口：将分数上传到服务器
url:
http://192.168.16.105:8080/uploadData
method: post
body: {"name":"zhangsan","score":"12"}
success: {"code":0}
error: {"code":-1,"error":"失败原因"}

name： 姓名
score: 分数，1-10

name： 姓名
score: 分数，1-10

Retrofit retrofit = new Retrofit.Builder()
.addConverterFactory(GsonConverterFactory.create())
.baseUrl("http://192.168.16.105:8080/")
.build();

/**

/**

Retrofit：中要用到的包

compile 'io.reactivex:rxjava:x.y.z'
compile 'io.reactivex:rxandroid:1.0.1'
compile 'com.squareup.retrofit2:retrofit:2.0.2'
compile 'com.squareup.retrofit2:converter-gson:2.0.2'
compile 'com.squareup.retrofit2:adapter-rxjava:2.0.2'

由于用到了Post请求，使用了JsonObject传递数据，所以导入：

compile 'com.alibaba:fastjson:1.1.56.android'

代码很low，仅供参考。
