巴士为您推荐： 微信小程序 wxapkg 解包器 c++版 免装py环境 90k

wxapkg的存储位置：/data/data/com.tencent.mm/MicroMsg/{User}/appbrand/pkg

{User} 为用户的用户名，pkg目录就是微信用于存放小程序和小游戏下载包的位置。

Python代码：

#!/usr/bin/env python2    # lrdcq  # usage python2 unwxapkg.py filename    import sys, os import struct    class WxapkgFile(object):   nameLen = 0  name = ""   offset = 0  size = 0    if len(sys.argv) < 2:   print 'usage: unwxapkg.py filename'  exit()     with open(sys.argv[1], "rb") as f:      root = os.path.dirname(os.path.realpath(f.name))   name = os.path.basename(f.name) + '_dir'    if len(sys.argv) > 2:     name = sys.argv[2]      #read header      firstMark = struct.unpack('B', f.read(1))[0]   print 'first header mark = ' + str(firstMark)      info1 = struct.unpack('>L', f.read(4))[0]   print 'info1 = ' + str(info1)      indexInfoLength = struct.unpack('>L', f.read(4))[0]   print 'indexInfoLength = ' + str(indexInfoLength)      bodyInfoLength = struct.unpack('>L', f.read(4))[0]   print 'bodyInfoLength = ' + str(bodyInfoLength)      lastMark = struct.unpack('B', f.read(1))[0]   print 'last header mark = ' + str(lastMark)      if firstMark != 0xBE or lastMark != 0xED:     print 'its not a wxapkg file!!!!!'    exit()      fileCount = struct.unpack('>L', f.read(4))[0]   print 'fileCount = ' + str(fileCount)      #read index      fileList = []      for i in range(fileCount):        data = WxapkgFile()     data.nameLen = struct.unpack('>L', f.read(4))[0]     data.name = f.read(data.nameLen)     data.offset = struct.unpack('>L', f.read(4))[0]     data.size = struct.unpack('>L', f.read(4))[0]        print 'readFile = ' + data.name + ' at Offset = ' + str(data.offset)        fileList.append(data)      #save files        for d in fileList:     d.name = '/' + name + d.name     path = root + os.path.dirname(d.name)        if not os.path.exists(path):       os.makedirs(path)        w = open(root + d.name, 'w')     f.seek(d.offset)     w.write(f.read(d.size))     w.close()        print 'writeFile = ' + root + d.name      f.close()
