QT案例 Qt调用WIMGAPI库，读取/修改/装载WIM、ESD格式的镜像文件

WIMGAPI库是 Windows 操作系统中的一个应用程序编程接口（API）可用于创建，编辑，提取浏览和部署 WIM、ESD格式的镜像文件。
这里只简单演示在Qt Creator， Mscv2017 Debug，WINDOWS 开发环境下的调用完整实例。

WIMGAPI描述

WIMGAPI （Windows Imaging API）是 Windows 操作系统中的一个应用程序编程接口（API），用于处理 Windows 映像（.wim）文件格式。Windows 映像是一种压缩的文件容器，可用于存储操作系统、应用程序和驱动程序等文件
注：https://www.cnblogs.com/suv789/p/17549323.html
WIMGAPI是适合WINDOWS 环境下处理WIM、ESD镜像格式的库，
常用方法说明：

• WIMCreateFile 创建新的图像文件或打开现有的图像文件。
• WIMApplyImage 将图像应用于Windows图像的目录路径(。wim)文件。
• WIMCaptureImage 从目录路径捕获图像，并将其存储在图像文件中。
• WIMCloseHandle 关闭打开的Windows imaging(。wim)文件或图像句柄。
• WIMCommitImageHandle 将已装载映像中的更改保存回. wim文件。
• WIMCopyFile 将现有文件复制到新文件中。通过回调函数通知应用程序它的进度。如果源文件包含验证数据，则在复制操作期间会验证文件的内容。
• WIMDeleteImage 从. wim (Windows映像)文件中删除映像，使其无法被访问。但是，文件资源仍然可供WIMSetReferenceFile功能。
• WIMDeleteImageMounts 从以前装载映像的所有目录中删除映像。
• WIMExportImage 从一个Windows映像(.wim)文件复制到另一个文件。
• WIMExtractImagePath 从Windows映像(.wim)文件复制到指定位置。
• WIMGetAttributes 返回存储在映像文件中的卷映像的数量。
• WIMGetImageCount 返回存储在Windows映像中的卷映像的数量。wim)文件。
• WIMGetImageInformation 返回有关中图像的信息。wim (Windows映像)文件。
• WIMGetMessageCallbackCount 返回图像库当前注册的回调例程的计数。
• WIMGetMountedImageHandle 返回一个WIM句柄和一个镜像句柄，对应于一个挂载的镜像目录。
• WIMGetMountedImageInfo 返回当前装载的映像列表。
• WIMGetMountedImageInfoFromHandle 查询已装载图像句柄的状态。
• WIMGetMountedImages 返回当前装载的映像列表。此功能已被取代WIMGetMountedImageInfo.
• WIMLoadImage 从Windows映像加载卷映像(。wim)文件。
• WIMMessageCallback 与一起使用的应用程序定义的函数WIMRegisterMessageCallback或者WIMUnregisterMessageCallback功能。
• WIMMountImage 将映像装入Windows映像(。wim)文件复制到指定目录。
• WIMMountImageHandle 将映像装入Windows映像(。wim)文件复制到指定目录。
• WIMRegisterLogFile 将用于调试或跟踪目的的日志文件注册到当前WIMGAPI会话中。
• WIMRegisterMessageCallback 用特定于图像的数据注册要调用的函数。有关可以处理的消息的信息，请参见信息.
• WIMRemountImage 重新激活以前装载到指定目录的已装载映像。
• WIMSetBootImage 将具有给定映像索引的映像标记为可启动。
• WIMSetImageInformation 将有关图像的信息存储在Windows图像(。wim)文件。
• WIMSetReferenceFile 启用WIMApplyImage和WIMCaptureImage使用替代的函数。文件资源的wim文件。当使用相似数据捕获多个图像时，这可以优化存储。
• WIMSetTemporaryPath 设置临时图像文件的存储位置。
• WIMSplitFile 启用大的Windows映像(。wim)文件分割成较小的部分，以便在较小形式的介质上复制或存储。
• WIMUnmountImage 卸载Windows映像中已装载的映像(。wim)文件从指定的目录。
• WIMUnmountImageHandle 从Windows映像中卸载映像(。wim ),它以前与一起安装WIMMountImageHandle功能。
• WIMUnregisterLogFile 出于调试或跟踪目的，从当前WIMGAPI会话中注销日志文件。
• WIMUnregisterMessageCallback 注销用特定于图像的数据调用的函数。

格式转换:
在涉及到windows api的接口调用时，
Qt开发环境下，这两个方法是绝对少不了的，毕竟传入路径的时候，都需要转换文本格式。

/*
 * Converts an UTF8 string to UTF-16 (allocate returned string)
 * Returns NULL on error
 */
static wchar_t* _utf8_to_wchar(const char* str)
{
    //    qDebug()<<"[_utf8_to_wchar] -->";
    int size = 0;
    wchar_t* wstr = NULL;

    if (str == NULL)
        return NULL;

    // Convert the empty string too
    if (str[0] == 0)
        return (wchar_t*)calloc(1, sizeof(wchar_t));

    // Find out the size we need to allocate for our converted string
    size = MultiByteToWideChar(CP_UTF8, 0, str, -1, NULL, 0);
    if (size <= 1)	// An empty string would be size 1
        return NULL;

    if ((wstr = (wchar_t*)calloc(size, sizeof(wchar_t))) == NULL)
        return NULL;

    if (utf8_to_wchar_no_alloc(str, wstr, size) != size) {
        sfree(wstr);
        return NULL;
    }
    return wstr;
}


/*
 * Converts an UTF-16 string to UTF8 (allocate returned string)
 * Returns NULL on error
 */
static char* _wchar_to_utf8(const wchar_t* wstr)
{
    int size = 0;
    char* str = NULL;

    /* Find out the size we need to allocate for our converted string */
    size = WideCharToMultiByte(CP_UTF8, 0, wstr, -1, NULL, 0, NULL, NULL);
    if (size <= 1) /* An empty string would be size 1 */
        return NULL;

    if ((str = (char*)calloc(size, 1)) == NULL)
        return NULL;

    if (wchar_to_utf8_no_alloc(wstr, str, size) != size) {
        free(str);
        return NULL;
    }

    return str;
}

获取镜像的相关信息

WIM、ESD镜像版本信息实际上就是一个XML格式保存的，
通过WIMGetImageInformation 获取
示例中整个操作是将XML写入了一个临时文件，
值得注意的是pfWIMCreateFile 打开WIM时需要将dwFlagsAndAttributes设置为WIM_UNDOCUMENTED_BULLSHIT
如果设置为0，测试部分镜像会无法加载；

 	TempFilePath tempObj; //一个用于生成临时文件的类
    //临时文件夹
    wchar_t* wtemp=tempObj.GetTempDirU();
    wchar_t* wimage;
    ///临时文件
    wchar_t* wdst=tempObj.GetTempFileNameU(1);
    ///XML格式信息
    wchar_t* wim_XMLinfo;
    HANDLE hWim = NULL;
    HANDLE hFile = NULL;
    DWORD dw = 0;
    DWORD dwFlagsAndAttributes=WIM_UNDOCUMENTED_BULLSHIT;
    //Image_path 镜像文件路径
    ///使用wimgapi库读取数据
    wimage=_utf8_to_wchar(Image_path.toStdString().c_str());
    //实例化API 
   	PF_INIT_OR_OUT(WIMCreateFile, Wimgapi);
    PF_INIT_OR_OUT(WIMSetTemporaryPath, Wimgapi);
    PF_INIT_OR_OUT(WIMCloseHandle, Wimgapi);
    PF_INIT_OR_OUT(WIMGetImageInformation, Wimgapi);
    PF_INIT_OR_OUT(WIMGetImageCount, Wimgapi);
 hWim = pfWIMCreateFile(wimage, WIM_GENERIC_READ, WIM_OPEN_EXISTING,dwFlagsAndAttributes , 0, NULL);
    if (hWim == NULL) {
        qDebug("  Could not access image: %d", GetLastError());
        goto out;
    }
    ///设置临时文件夹路径
    if (!pfWIMSetTemporaryPath(hWim, wtemp)) {
        qDebug("  Could not set temp path: %d", GetLastError());
        goto out;
    }
	
	///获取镜像包含的系统数量
    int Image_Count=pfWIMGetImageCount(hWim);
    if(Image_Count==0)
        qDebug("  Could not get image count: %d", GetLastError());
    qDebug()<<"[Image_Count] "<<Image_Count;


    ///获取 系统的xml信息
    if (!pfWIMGetImageInformation(hWim, &wim_XMLinfo, &dw) || (dw == 0)) {
        qDebug("  Could not access WIM info: %d", GetLastError());
        goto out;
    }

    ///写入临时文件
    hFile = CreateFileW(wdst, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ,
                        NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
    if ((hFile == INVALID_HANDLE_VALUE)
            || (!WriteFile(hFile, wim_XMLinfo, dw, &dw, NULL))) {
        qDebug("  Could not extract file: %s", GetLastError());
        goto out;
    }

    CloseHandle(hFile);
    hFile=INVALID_HANDLE_VALUE;

    ///打开xml读取数据
    //Parser_XML(QString::fromWCharArray(wdst));
out:
    if ( (hWim != NULL)) {
        qDebug("Closing: %s", Image_path.toStdString().c_str());
        if (hWim != NULL)
            pfWIMCloseHandle(hWim);
    }
    if(hFile != INVALID_HANDLE_VALUE)
        CloseHandle(hFile);

    safe_free(wtemp);
    safe_free(wimage);
    safe_free(wdst);

导出指定系统中的文件

一个WIM、ESD镜像文件中至少包含一个系统镜像，
pfWIMLoadImage加载镜像时都需要先设置一个临时文件夹；
默认镜像索引从1开始，小于等于镜像系统数量；

void Lib_Wimgapi::Export_File_by(int index,QString wimpath,QString outfile)
{
    TempFilePath tempObj;
    //临时文件夹
    wchar_t* wtemp=tempObj.GetTempDirU();
    ///镜像路径
    wchar_t* wimage=_utf8_to_wchar(Image_path.toStdString().c_str());
    ///WIM 镜像路径 如 windows\\boot.exe
    wchar_t* wsrc=_utf8_to_wchar(wimpath.toStdString().c_str());
    ///输出路径 如 C:\\Users\\admin\\Desktop\\boot.exe
    wchar_t* wdst=_utf8_to_wchar(outfile.toStdString().c_str());
    HANDLE hWim = NULL;
    HANDLE hImage=NULL;
    DWORD dw=0;

	///实例化函数方法
    PF_INIT_OR_OUT(WIMCreateFile, Wimgapi);
    PF_INIT_OR_OUT(WIMSetTemporaryPath, Wimgapi);
    PF_INIT_OR_OUT(WIMCloseHandle, Wimgapi);
    PF_INIT_OR_OUT(WIMLoadImage, Wimgapi);
    PF_INIT_OR_OUT(WIMExtractImagePath, Wimgapi);


    hWim = pfWIMCreateFile(wimage, WIM_GENERIC_READ, WIM_OPEN_EXISTING,WIM_UNDOCUMENTED_BULLSHIT , 0, NULL);
    if (hWim == NULL) {
        qDebug("  Could not access image: %d", GetLastError());
        goto out;
    }
    ///设置临时文件夹路径
    if (!pfWIMSetTemporaryPath(hWim, wtemp)) {
        qDebug("  Could not set temp path: %d", GetLastError());
        goto out;
    }

	///至少为1
    int WIM_INDEX=qMin(qMax(1,index),Image_Count);
    hImage = pfWIMLoadImage(hWim, WIM_INDEX);
    if (hImage == NULL) {
        qDebug("  Could not set index: %d", GetLastError());
        goto out;
    }
	
	///输出文件
    if (!pfWIMExtractImagePath(hImage, wsrc, wdst, dw)) {
        qDebug("  Could not extract file: %d", GetLastError());
        goto out;
    }

out:
    if (hWim != NULL || hWim != hImage) {
        qDebug("Closing: %s", Image_path.toStdString().c_str());
        if (hWim != NULL)
            pfWIMCloseHandle(hWim);
        if (hImage != NULL)
            pfWIMCloseHandle(hImage);
    }
    safe_free(wtemp);
    safe_free(wimage);
    safe_free(wsrc);
    safe_free(wdst);
}

获取镜像目录结构（装载/卸载镜像）

WIMGAPI库中貌似没有可以直接获取目录结构的函数，写示例的时候我是先通过
加载镜像(pfWIMLoadImage)->
装载镜像(WIMMountImageHandle)->
读取目录结构(文件夹遍历)->
卸载镜像(WIMUnmountImageHandle)
这个流程来获取目录结构的；

 	TempFilePath tempObj;
    HANDLE hWim = NULL;
    HANDLE hImage = NULL;
    ///Image_path
    wchar_t* wimage = _utf8_to_wchar(Image_path.toStdString().c_str());
    //临时文件夹
    wchar_t* wtemp=tempObj.GetTempDirU();
	//用于装载的路径
    QDir tempMountDir(QString::fromWCharArray(wtemp)+"\\TempMount_WIMGAPI");
    if(!tempMountDir.exists())
        tempMountDir.mkpath(QString::fromWCharArray(wtemp)+"\\TempMount_WIMGAPI");
    wchar_t* wdst=_utf8_to_wchar(QString(QString::fromWCharArray(wtemp)+"\\TempMount_WIMGAPI").toStdString().c_str());
    QString TempFile=QString::fromWCharArray(wdst);
    qDebug()<<"临时装载路径: "<<TempFile;
    //PF_INIT_OR_OUT(WIMRegisterMessageCallback, Wimgapi);
    PF_INIT_OR_OUT(WIMCreateFile, Wimgapi);
    PF_INIT_OR_OUT(WIMSetTemporaryPath, Wimgapi);
    PF_INIT_OR_OUT(WIMLoadImage, Wimgapi);
    PF_INIT_OR_OUT(WIMApplyImage, Wimgapi);
    PF_INIT_OR_OUT(WIMCloseHandle, Wimgapi);
    //PF_INIT_OR_OUT(WIMUnregisterMessageCallback, Wimgapi);
    PF_INIT_OR_OUT(WIMMountImageHandle, Wimgapi);
    PF_INIT_OR_OUT(WIMUnmountImageHandle, Wimgapi);

// 调试信息
//    if (pfWIMRegisterMessageCallback(NULL, (FARPROC)WimProgressCallback, NULL) == INVALID_CALLBACK_VALUE) {
//        qDebug("  Could not set progress callback: %d", GetLastError());
//        goto out;
//    }

    hWim = pfWIMCreateFile(wimage, WIM_GENERIC_READ|WIM_GENERIC_MOUNT, WIM_OPEN_EXISTING,WIM_UNDOCUMENTED_BULLSHIT , 0, NULL);
    if (hWim == NULL) {
        qDebug("  Could not access image: %d", GetLastError());
        goto out;
    }

    if (!pfWIMSetTemporaryPath(hWim, wtemp)) {
        qDebug("  Could not set temp path: %d", GetLastError());
        goto out;
    }
    int WIM_INDEX=qMax(1,index.toInt());
    hImage = pfWIMLoadImage(hWim, WIM_INDEX);
    if (hImage == NULL) {
        qDebug("  Could not set index: %d", GetLastError());
        goto out;
    }

    ///清除历史缓存
    //! 方案一 用这种方法可以检查文件目录 但是无法获取文件的属性
//    Fetch_Files.clear();
//    // Run a first pass using WIM_FLAG_NO_APPLY to count the files
//    if (!pfWIMApplyImage(hImage, wdst, WIM_FLAG_NO_APPLY)) {
//        qDebug("  Could not count the files to apply: %d", GetLastError());
//        goto out;
//    }

    //! 方案二 通过装载卸载的方式 获取文件目录结构
    if(!pfWIMMountImageHandle(hImage,wdst,WIM_FLAG_MOUNT_READONLY))
    {
        qDebug("Could not Mount Image: %d", GetLastError());
        goto out;
    }

	//遍历目录结构
    //Lib_Deploy_Environment::getInstance().EnumerateFiles(TempFile,Fetch_Files);
    
    //! 如果需要对镜像镜像修改 可以在此处操作文件目录/文件 然后提交保存
    //!WIMCommitImageHandle 保存装载后的更改!

    if(!pfWIMUnmountImageHandle(hImage,0))
    {
        //dism /Get-MountedWimInfo
        //dism /Cleanup-Wim
        //CMD_WRITE("dism /Cleanup-Wim");
        qDebug("Could not Unmount Image: %d", GetLastError());
    }
out:
    if ((hImage != NULL) || (hWim != NULL)) {
        qDebug("Closing: %s", Image_path.toStdString().c_str());
        if (hImage != NULL)
            pfWIMCloseHandle(hImage);
        if (hWim != NULL)
            pfWIMCloseHandle(hWim);
    }
//    if (pfWIMUnregisterMessageCallback != NULL)
//        pfWIMUnregisterMessageCallback(NULL, (FARPROC)WimProgressCallback);
    safe_free(wimage);
    safe_free(wdst);
    safe_free(wtemp);

其中需要注意的是：
如果因为各种原因卸载或者装载失败，都需要调用Windwos系统自带的Dism.exe删除不完整的记录
CMD执行 dism.exe /Cleanup-Wim

提取镜像到指定目录

通过pfWIMApplyImage 提取镜像时，可以加上WIMRegisterMessageCallback的回调函数，获取提取文件进度，也可以实现简单的进度条效果，

//!回调函数
static DWORD WimProgressCallback(DWORD dwMsgId, WPARAM wParam, LPARAM lParam, PVOID pvIgnored)
{
    //qDebug()<<"[dwMsgId] "<
    PBOOL pbCancel = NULL;
    PWIN32_FIND_DATA pFileData;
    const char* level = NULL;
    uint64_t size;

提示：
pfWIMApplyImage 函数的

• WIM_FLAG_NO_APPLY 属性不提取文件，只会在回调函数中返回WIM_MSG_PROCESS信号，同时可输出文件路径，可用于统计文件目录数量
• WIM_FLAG_FILEINFO 属性会提取文件，按目录结构写入指定文件夹中，会在回调函数中返回WIM_MSG_FILEINFO信号。
