我正在进行改造并通过post方法向服务器发送请求我现在得到这个json的响应，看到这是我发送到服务器的帖子。
使用此对象发布的adreess类
{
"years":"1855",
"months":"6",
"skills":1
}
现在我必须在技能中实现数组内部的数组如何发布
{
"years":"1",
"months":"6",
"skills":["1","2","3"],
}
如何在改造中获取对象内的数组 我正在使用这样的界面
Call<AddressResponce> address(@Body Adreess adreess);
答案 0 :(得分：4)
大致看起来像这样：
RequestBody类应该有一个数组来保存该技能列表
class RequestBody {
int years;
int months;
int[] skills;
}
@POST(“url”)
Call<AddressResponce> address(@Body RequestBody requestbody);
看看它是否有效。

package com.example;
import java.util.List;

我希望它对你有用..！
