Python에서 CS Counter-Strike 서버 정보를 쿼리하는 방법

前言

服务器的相关知识曾经让我非常困惑。我相信还有很多的Python开发者和我有着类似的遭遇。本文主要介绍了python下如何查询CS反恐精英的服务器信息，有需要的可以参考学习。

CS反恐精英1.5版本示例代码

#!/bin/env python
 
import urllib2, base64, sys, getopt
import re
import socket
 
def Usage ():
  print "Usage: hlds.py -h 127.0.0.1 -p 27015"
  sys.exit(2)
 
def main ():
 
  # Default values
  host = "localhost"
  port = ""
 
  if len(sys.argv) < 1:
    Usage()
 
  try:
    opts, args = getopt.getopt(sys.argv[1:], "h:p:a:")
  except getopt.GetoptError:
    Usage()
 
  # Assign parameters as variables
  for opt, arg in opts :
    if opt == "-h" :
      host = arg
    if opt == "-p" :
      port = arg
 
  sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
  port = int(port)
  sock.settimeout(10)
  sock.connect((host, port))
  sock.send(&#39;\xFF\xFF\xFF\xFF\x69\x6E\x66\x6F\x73\x74\x72\x69\x6E\x67\x0A\00&#39;)
 
  request=sock.recv(1400)
  sock.close()
  server_info=request.replace(&#39;\xFF&#39;, &#39;&#39;)
 
  buffer = re.findall(r&#39;\d+&#39;, server_info)
  print buffer[6]
 
if __name__ == "__main__":
 main()

CS反恐精英1.6版本示例代码

#!/bin/env python
 
import urllib2, base64, sys, getopt
import re
import socket
 
def Usage ():
  print "Usage: hlds.py -h 127.0.0.1 -p 27015"
  sys.exit(2)
 
def main ():
 
  # Default values
  host = "localhost"
  port = ""
 
  if len(sys.argv) < 1:
    Usage()
 
  try:
    opts, args = getopt.getopt(sys.argv[1:], "h:p:a:")
  except getopt.GetoptError:
    Usage()
 
  # Assign parameters as variables
  for opt, arg in opts :
    if opt == "-h" :
      host = arg
    if opt == "-p" :
      port = arg
 
  sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
  port = int(port)
  sock.settimeout(10)
  sock.connect((host, port))
  sock.send(&#39;\xFF\xFF\xFF\xFF\x54\x53\x6F\x75\x72\x63\x65\x20\x45\x6E\x67\x69\x6E\x65\x20\x51\x75\x65\x72\x79\x00&#39;)
 
  request=sock.recv(1400)
  sock.close()
  #server_info=request.replace(&#39;\xFF&#39;, &#39;&#39;)
  print request
 
  #buffer = re.findall(r&#39;\d+&#39;, server_info)
  #print buffer[6]
  #print buffer
 
if __name__ == "__main__":
 main()
