这是一个创建于 3028 天前的主题，其中的信息可能已经有所发展或是发生改变。
也不知道这个是不是哈希得来的，希望兄弟们可以帮忙看看，出出主意。
https://s3-ap-southeast-1.amazonaws.com/mtpdm/2016-08-02/10-07/1002_0953_20160802100400_0c37f9.jpg
以上是一个图片链连， 1002_0953_20160802100400_0c37f9.jpg
1002 —— 0953 是不变的，代表摄像头吧
20160802100400 代表 YYYYMMDDHHMMSS
0c37f9 是个随机生成的 6 位字符串或者哈希值，
现在如果我能够了解这个值是如何得来的，就可以直接去 AWS 下载图片了，兄弟们有没有高见？可以把时间戳和摄像头哈希成 6 位的字符么？我用的哈希都是比这个 6 位数长的，不好意思，对这个不熟。
API 文档在 这里
以下是 API 的输出，可以看到所以图片的链接都是有个随机数在后面的。

... 你确认这是哈希而不是随机字符串？

xianlin OP 不确定啊，如果是随机的串那就更不好办了，无解了吧。
