看到别人的微信小程序眼馋了怎么办?拿过来改改就是我们自己的了,下面教大家怎么将别人的微信小程序变成自己的。要实现这样的功能,必须先拿到微信小程序的安装包。苹果的程序拿不到,我们只能拿到安卓的微信小程序安装包。
安卓微信小程序在安卓微信的安装目录中,下面给个参考:/data/data/com.tencent.mm/MicroMsg/账号标识/appbrand/pkg/
C#微信小程序解包类
/// <summary> /// 微信小程序解包 /// </summary> public class UnWxapkg { FileStream fileStream = null; BinaryReader binaryReader = null; Action<string, byte[]> action = null; string message; public UnWxapkg(string path) { fileStream = new FileStream(path, FileMode.Open, FileAccess.Read); binaryReader = new BinaryReader(fileStream); } public string Go(Action<string, byte[]> action_ = null) { action = action_; if (!ReadFirstMark()) { return message; } ReadInfo(); int indexInfoLength = ReadindexInfoLength(); int bodyInfoLength = ReadBodyInfoLength(); if (!ReadLastMark()) { return message; } int fileCount = ReadFileCount(); for (int i = 0; i < fileCount; i++) { ReadFile(); } binaryReader.Dispose(); fileStream.Dispose(); binaryReader.Close(); fileStream.Close(); return "完成"; } /// <summary> /// 读取标志位 用于判断是否为小程序包 /// </summary> /// <param name="binaryReader"></param> public bool ReadFirstMark() { if (ReadInt(1) != 190) { message = "当前文件不是微信小程序包!"; return false; } return true; } /// <summary> /// 读取小程序附加信息 /// </summary> /// <returns></returns> public int ReadInfo() { return (int)binaryReader.ReadUInt32(); } /// <summary> /// 读取索引长度 /// </summary> /// <returns></returns> public int ReadindexInfoLength() { return ReadInt(4); } /// <summary> /// 读取数据长度 /// </summary> /// <returns></returns> public int ReadBodyInfoLength() { return ReadInt(4); } /// <summary> /// 读取结尾标记 /// </summary> /// <returns></returns> public bool ReadLastMark() { if (ReadInt(1) != 237) { message = "当前文件不是微信小程序包!"; return false; } return true; } /// <summary> /// 读取文件数量 /// </summary> /// <returns></returns> public int ReadFileCount() { return ReadInt(4); } /// <summary> /// 读文件信息 /// </summary> public void ReadFile() { int fileNameLength = ReadInt(4); byte[] fileNameb = binaryReader.ReadBytes(fileNameLength); string fileName = System.Text.Encoding.Default.GetString(fileNameb); int file_start = ReadInt(4); int file_length = ReadInt(4); //先缓存当前索引 long currindex = binaryReader.BaseStream.Position; binaryReader.BaseStream.Position = file_start; byte[] file_content = binaryReader.ReadBytes(file_length); //还原索引 binaryReader.BaseStream.Position = currindex; if (action != null) { action.Invoke(fileName, file_content); } } /// <summary> /// 读整数 /// </summary> /// <param name="length"></param> /// <returns></returns> int ReadInt(int length) { int num = 0; for (int i = 0; i < length; i++) { num = (num << 8) + ((int)binaryReader.ReadByte()); } return num; } }
简单使用
string path = "小程序包路径"; UnWxapkg unWxapkg = new UnWxapkg(path); Console.WriteLine("开始解包!"); string mess = unWxapkg.Go((x,x1)=> { //解包后的存储地址 string filePath = @"E:/123/1" + x; string dirPath = Path.GetDirectoryName(filePath); //开始写出文件 if (!Directory.Exists(dirPath)) { Directory.CreateDirectory(dirPath); } FileStream stream = new FileStream(filePath, FileMode.OpenOrCreate); stream.Write(x1, 0, x1.Length); stream.Dispose(); stream.Close(); Console.WriteLine(x1.Length.ToString()+" "+ @"E:/123/1" + x); });
解包后效果如下图
