1. 常用交互操作

  • 远程连接 remote(host,port)

  • send(string) 发送string

  • sendline(string) 发送string及换行符

  • sendafter(magic,string) 接收到magic后发送string

  • sendlineafter(magic,string) 接收到magic后发送string及换行符

  • recvn(N)接受N字节字符

  • recvline()接受一行输出

  • recvlines(N)接受N行输出

  • recvuntil(magic)一直接受直到出现magic

  • clean()丢掉所有缓冲

eg1:

  • moectf NotEnoughTime

    主要就是以字节传输转成字符串a.decode要注意,然后就是b’ ‘要注意
