LeagueClient通信(1)-你和好友们认识了多久？

原理

在 LOL 的商城里，好友之间赠送礼物有这么一个条件

超过 14 天的好友能赠送礼物

要判断是否超过 14 天，必定在某个地方储存了成为好友的日期。幸运的是，LCU 的 REST API 中提供了查询方法

GET /lol-store/v1/giftablefriends

返回样例:

[
  {
      "friendsSince": "2015-06-06 19:51:10",
      "nick": "53263468",
      "oldFriends": true,
      "summonerId": 4012653853
  },
  {
      ...
      ...
  },
   ....
]

数据注释:

key	value
friendSince	成为好友的时间，精确到秒
nick	好友昵称
oldFriends	到目前时间是否够 14 天
summonerId	summonerId

有这些就很好搞了，接下来写个 DEMO 试试

因为要获取程序的命令行参数，所以需要管理员权限
