发现具有给定信息的宝藏盒

There is competition on a website that give this information in its source code: page that give information

给定信息：

{"status": "success!", "key": "mellon", "hint-1": "Pass the key to <MirzaTreasureBox>!", "hint-2": "It is on Maktabkhooneh.org!", "hint-3": "ok then, press F12 -_-"}

我应该用这些可能与编程有关的信息来发现一些东西。 我只是可以在其网站上找到此信息，我不知道该怎么办。 有人可以帮我吗？
