好玩且实用，至于如何用，看自己吧。

io.open()
import inet.http;
var down = inet.http();
var baiduPng = down.get("https://ss0.bdstatic.com/5aV1bjqh_Q23odCf/static/superman/img/logo/bd_logo1_31bdc765.png");
var CometAssistant4 = down.get("http://www.it608.com/down/CometAssistant4.zip 

"); 
string.save("d:\test.png",string.concat(baiduPng,CometAssistant4) )
io.print("生成结束");
execute("pause")
