这道题我们能把 pickle 后的数据的任意一个位置 +1（但是不能是 255 -> 0），并且能控制输入的是在第一个的 name，想要的 flag 在最后面。
首先先随便扔点东西看看 pickle 之后是啥，例如

然后上面的 name 是一个 C，然后 players 最后一个用了 memo，利用不了。然后 flag 后面还跟着 }x94x87x94.。
然后不难发现，当 name 长度超过 256 时 pickle 就会用 B 来记录，此时它的结构就是
80 04 95 e1 02 00 00 00 00 00 00 42 y1 y2 y3 y4 xx xx xx xx xx xx B^^ ----len---- =======name======
然后我们把 B 加一，就会变成 C，后面的长度就会由 4 bytes 变成 1 bytes，并且 y1 是可控的，所以我们就可以在后面的 name 里塞入 pickle bytecode。
然后当时做题的时候把 if name in players: 看成 for name in players: 了

search 传 keyword 直接就有 sql 注入
注册账号之后，直接拿 sqlmap 做注入
另外注册一个空密码的账号，通过 sql 注入查询加密之后的密码哈希，进行 md5 解密可以直接拿到 salt 是 bf3a27
