我正在创建一个套接字服务器。此服务器正在处理十六进制值。

我能够建立与服务器的连接。但是无法读取客户端的十六进制值,也无法将十六进制值放到客户端。

require "socket"


def listenserver (server)
 @buff1 =[160, 124]
 client = server.accept
 puts  "#{client.inspect} is accepted"
 client.print "0x%02x" % @buff1[0]
 client.print"0x%02x" % @buff1[1]
 puts "#{@buff1.inspect}"
 puts "0x%02x" % @buff1[0]
 client.close
 puts "#{client} is gone"
end

server = TCPServer.new('x.x.x.x', 12345)
loop do
 puts "Started TCPServer"
 listenserver(server)

end

您要找的是Array.packString.unpack

Ruby Docs中的示例代码:

Array.pack

a = [ "a", "b", "c" ]  
a.pack("A3A3A3")  
=> "a  b c "

Sting.unpack

"\xfe\xff\xfe\xff".unpack('sS')
=> [-2, 65534]

"whole".unpack('xax2aX2aX1aX2a')
=> ["h", "e", "l", "l", "o"]
