def list_wifi  
  wifi_pwds = Hash.new  

  # 获取所有wifi文件  
  o1 = get_cmd_result("netsh wlan show profiles")  
  # 获取所有匹配结果  
  wifi_names = o1.scan(/所有用户配置文件\s*:\s*(.*?)\n/m)  
  unless wifi_names.empty?  
    wifi_names.each do |wifi_name|  
      o2 = get_cmd_result("netsh wlan show profile name=\"#{wifi_name[0]}\" key=clear")  
      wifi_pwd = o2.scan(/关键内容\s*:\s*(.*)\n/)  
      wifi_pwds.update({wifi_name[0] => wifi_pwd[0]})  
    end  
  end  wifi_pwds  
end
