跟上一篇类似,我们也需要对APK的一些诸如umengkey,ADkey,TalkingData进行验证,那么我们同样需要解压apk文件,然后提取其中的AndroidManifest.xml。然后解析xml对内容进行分析对比。
1.解压apk文件
if (Path.GetExtension(filePath).Equals(".apk")) { // 获取应用名称 String appName = Path.GetFileNameWithoutExtension(filePath); // 导出目录 String outPath = "tempandroid\\" + appName; // 创建解压流 ZipInputStream s = new ZipInputStream(File.OpenRead(filePath)); String AndroidManifestName = "AndroidManifest.xml"; ZipEntry theEntry; bool found = false; while ((theEntry = s.GetNextEntry()) != null) { Console.WriteLine(theEntry.Name); // 获取解压文件名 string fileName = Path.GetFileName(theEntry.Name); // 遍历查找配置文件 if (AndroidManifestName != null) { if (fileName.Equals(AndroidManifestName)) { found = true; if (outPath.Length > 0) { Directory.CreateDirectory(outPath); } using (FileStream streamWriter = File.Create(outPath + "\\" + AndroidManifestName)) { int size = 2048; byte[] data = new byte[2048]; while (true) { size = s.Read(data, 0, data.Length); if (size > 0) { streamWriter.Write(data, 0, size); } else { break; } } streamWriter.Flush(); streamWriter.Close(); // 执行解密操作,由于签名的xml必须解密,不然是二进制文件 String execString = "java -jar " + decodeXmljar + " " + outPath + "\\" + AndroidManifestName + " > " + outPath + "\\AndroidManifest2.xml"; runcommand(execString); // 执行文件替换操作 Thread.Sleep(3000); File.Delete(outPath + "\\" + AndroidManifestName); File.Move(outPath + "\\AndroidManifest2.xml", outPath + "\\" + AndroidManifestName); } break; } } } s.Close(); if (found == false) { logAppend(appName + "------- 无效", false, false); logAppend(Environment.NewLine, false, false); } }
2.解压出来的xml文件是二进制文件,必须要解密,用的是AXMLPrinter2.jar,具体实现如下
private String decodeXmljar = "AXMLPrinter2.jar"; // 执行解密操作 String execString = "java -jar " + decodeXmljar + " " + outPath + "\\" + AndroidManifestName + " > " + outPath + "\\AndroidManifest2.xml"; runcommand(execString); //执行文件替换操作 Thread.Sleep(3000); File.Delete(outPath + "\\" + AndroidManifestName); File.Move(outPath + "\\AndroidManifest2.xml", outPath + "\\" + AndroidManifestName); /** * 运行命令 * */ private void runcommand(String command) { Process p = new Process(); p.StartInfo.FileName = "cmd.exe"; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardInput = true; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardError = true; p.StartInfo.CreateNoWindow = true; p.StartInfo.WorkingDirectory = Application.StartupPath; try { p.Start(); Console.WriteLine("command:" + command + " &exit"); p.StandardInput.WriteLine(command); p.StandardOutput.Close(); p.Close(); } catch (Exception e1) { Console.WriteLine("error" + e1.Message); } }
3.解密文件后,我们就可以使用xml读取去处理,这边我们引用的包是System.Xml,C#自带
XmlDocument doc = new XmlDocument(); // 加载Xml文件 doc.Load(pathInfo); // 获取根节点 XmlElement rootElem = doc.DocumentElement; // 获取person子节点集合 XmlNodeList metadatanodes = rootElem.GetElementsByTagName("meta-data"); String appKey = rootElem.GetAttribute("package"); String mangguokey = ""; String talkingData = ""; String umengKey = ""; String qihuKey = ""; foreach (XmlNode metadatanode in metadatanodes) { if(metadatanode.NodeType == XmlNodeType.Element) { XmlElement nodeelement = (XmlElement)metadatanode; String name = nodeelement.GetAttribute("android:name"); if("UMENG_APPKEY".Equals(name)) { umengKey = nodeelement.GetAttribute("android:value"); } else if("TD_APP_ID".Equals(name)) { talkingData = nodeelement.GetAttribute("android:value"); } else if("MANGO_ID".Equals(name)) { mangguokey = nodeelement.GetAttribute("android:value"); } else if ("QH_360_ID".Equals(name)) { qihuKey = nodeelement.GetAttribute("android:value"); } } }
综合以上三步,我们可以很简单的提取到xml中的信息进行比对。
结语
- 受益,学会了提取apk中的AndroidManifest.xml中的信息
