最近很流行的一款微信小游戏《海盗来了》,用来打发时间还不错,就是建岛和转盘太慢了,于是用 Fiddler 抓了下包,分析了下请求报文,发现所有的请求都需要 sign 签名,尝试了几次都得不到签名值,于是搞了个安卓模拟器,把小游戏的源码拷出来分析了下。
《海盗来了》小游戏的 game.js 源码
分析源码发现,请求的签名算法就是普通的字典排序,拼成 URL 后把&符号去掉,再进行 MD5 签名!
例如:sign=md5(uid=666t=666secret=666)
试了下,还是可以用的,但请求的频率不宜过高,我的一个号就是这样被封了,所以。。。
运行结果:
param >> bet=1&isWxGame=true&secret=2ca123ee4a764293af00b139781c291e&t=1525228492778&uid=199471083
sign >> 9d1506d57913290ac439dc134990bde4
转盘 >> {"data":{"money":1337034,"maxEnergy":50,"energy":0,"recoverEnergy":6,"timeToRecover":3135,"shields":2,"wantedCount":0,"ShipwreckCount":0,"cookieCount":0,"potionCount":0,"hatchCount":0,"hornCount":0,"miniShieldCount":0,"monthCardExpired":0,"gotNewbieGift":false,"gotOccasionalGift":true,"gotDailyShop":true,"allInOnePiece":0,"killTitanCannonBall":30,"summonStone":1,"puffer":0,"lolly":0,"guildMedal":0,"doubleMoneyCard":0,"stealIslands":null,"attackTarget":null,"revengeList":null,"rollerItem":{"index":1,"type":0,"value":48000},"betCount":1,"shareCoinFactor":0},"errcode":0,"errmsg":""}

Talk is cheap, show you the code :
解释一下,这里用到了一个 RelynSpider 类,是我自己的爬虫类,其实就是 POST 请求,用 HttpClient 就可以实现,POST 的时候,记得用微信的 User-Agent,相关的方法我都贴在最后面了。

RelynSpider 类中的 formatUrlMap 方法:

RelynSpider 类中的 md5 方法:
/** * md5加密方法 * @param text * @return */ public static String md5(String text) { String result=""; try { MessageDigest md = MessageDigest.getInstance("MD5"); md.update(text.getBytes("UTF-8")); byte b[] = md.digest(); int i; StringBuffer buf = new StringBuffer(""); for (int offset = 0; offset < b.length; offset++) { i = b[offset]; if (i < 0) i += 256; if (i < 16) buf.append("0"); buf.append(Integer.toHexString(i)); } result = buf.toString(); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } return result; }
