我是想做一个使用DirectInput实时获取输入设备的数据并且记录下来 然后利用DirectInput的sendinput函数做1比1的回放模拟操作 请用C++帮忙实现一下

以下是一个简单的使用DirectInput实时获取输入设备数据并记录下来的示例代码。它将捕获鼠标和键盘的输入，并将它们记录在文件中：

#include <Windows.h>
#include <dinput.h>
#include <fstream>

#pragma comment(lib, "dinput8.lib")
#pragma comment(lib, "dxguid.lib")

// 定义键盘和鼠标的输入状态
struct InputState
{
    BYTE keyboardState[256];
    DIMOUSESTATE mouseState;
};

// 全局变量
LPDIRECTINPUT8 g_pDI = nullptr;
LPDIRECTINPUTDEVICE8 g_pKeyboard = nullptr;
LPDIRECTINPUTDEVICE8 g_pMouse = nullptr;
InputState g_inputState;

// 初始化DirectInput设备
bool InitDirectInput(HWND hWnd)
{
    HRESULT hr;

    // 创建DirectInput对象
    hr = DirectInput8Create(GetModuleHandle(nullptr), DIRECTINPUT_VERSION, IID_IDirectInput8, (void**)&g_pDI, nullptr);
    if (FAILED(hr))
        return false;

    // 创建键盘设备
    hr = g_pDI->CreateDevice(GUID_SysKeyboard, &g_pKeyboard, nullptr);
    if (FAILED(hr))
        return false;

    // 设置键盘数据格式
    hr = g_pKeyboard->SetDataFormat(&c_dfDIKeyboard);
    if (FAILED(hr))
        return false;

    // 设置键盘协作级别
    hr = g_pKeyboard->SetCooperativeLevel(hWnd, DISCL_FOREGROUND | DISCL_NONEXCLUSIVE);
    if (FAILED(hr))
        return false;

    // 创建鼠标设备
    hr = g_pDI->CreateDevice(GUID_SysMouse, &g_pMouse, nullptr);
    if (FAILED(hr))
        return false;

    // 设置鼠标数据格式
    hr = g_pMouse->SetDataFormat(&c_dfDIMouse);
    if (FAILED(hr))
        return false;

    // 设置鼠标协作级别
    hr = g_pMouse->SetCooperativeLevel(hWnd, DISCL_FOREGROUND | DISCL_NONEXCLUSIVE);
    if (FAILED(hr))
        return false;

    // 设置鼠标采样率
    DIPROPDWORD diprop;
    diprop.diph.dwSize = sizeof(DIPROPDWORD);
    diprop.diph.dwHeaderSize = sizeof(DIPROPHEADER);
    diprop.diph.dwObj = 0;
    diprop.diph.dwHow = DIPH_DEVICE;
    diprop.dwData = 1000;
    hr = g_pMouse->SetProperty(DIPROP_SAMPLEPERIOD, &diprop.diph);
    if (FAILED(hr))
        return false;

    return true;
}

// 释放DirectInput设备
void ReleaseDirectInput()
{
    if (g_pKeyboard)
    {
        g_pKeyboard->Unacquire();
        g_pKeyboard->Release();
        g_pKeyboard = nullptr;
    }

    if (g_pMouse)
    {
        g_pMouse->Unacquire();
        g_pMouse->Release();
        g_pMouse = nullptr;
    }

    if (g_pDI)
    {
        g_pDI->Release();
        g_pDI = nullptr;
    }
}

// 获取键盘输入状态
void GetKeyboardState()
{
    HRESULT hr;

    // 获取键盘输入状态
    hr = g_pKeyboard->GetDeviceState(sizeof(g_inputState.keyboardState), &g_inputState.keyboardState);
    if (FAILED(hr))
    {
        // 如果设备失去了焦点，尝试重新获取焦点
        hr = g_pKeyboard->Acquire();
        while (hr == DIERR_INPUTLOST)
            hr = g_pKeyboard->Acquire();
    }
}

// 获取鼠标输入状态
void GetMouseState()
{
    HRESULT hr;

    // 获取鼠标输入状态
    hr = g_pMouse->GetDeviceState(sizeof(g_inputState.mouseState), &g_inputState.mouseState);
    if (FAILED(hr))
    {
        // 如果设备失去了焦点，尝试重新获取焦点
        hr = g_pMouse->Acquire();
        while (hr == DIERR_INPUTLOST)
            hr = g_pMouse->Acquire();
    }
}

// 记录输入状态到文件
void RecordInputState(const InputState& inputState, std::ofstream& ofs)
{
    ofs.write((const char*)&inputState, sizeof(inputState));
}

// 回放输入状态
void ReplayInputState(const InputState& inputState)
{
    // 发送键盘输入
    for (int i = 0; i < 256; i++)
    {
        if (g_inputState.keyboardState[i] != inputState.keyboardState[i])
        {
            INPUT input;
            input.type = INPUT_KEYBOARD;
            input.ki.wVk = i;
            input.ki.dwFlags = (inputState.keyboardState[i] & 0x80) ? 0 : KEYEVENTF_KEYUP;
            SendInput(1, &input, sizeof(INPUT));
        }
    }

    // 发送鼠标输入
    if (memcmp(&g_inputState.mouseState, &inputState.mouseState, sizeof(DIMOUSESTATE)) != 0)
    {
        INPUT input;
        input.type = INPUT_MOUSE;
        input.mi.dx = inputState.mouseState.lX;
        input.mi.dy = inputState.mouseState.lY;
        input.mi.mouseData = inputState.mouseState.lZ;
        input.mi.dwFlags = MOUSEEVENTF_MOVE;
        if (inputState.mouseState.rgbButtons[0] & 0x80)
            input.mi.dwFlags |= MOUSEEVENTF_LEFTDOWN;
        if (inputState.mouseState.rgbButtons[1] & 0x80)
            input.mi.dwFlags |= MOUSEEVENTF_RIGHTDOWN;
        if (inputState.mouseState.rgbButtons[2] & 0x80)
            input.mi.dwFlags |= MOUSEEVENTF_MIDDLEDOWN;
        if (g_inputState.mouseState.rgbButtons[0] & 0x80 && !(inputState.mouseState.rgbButtons[0] & 0x80))
            input.mi.dwFlags |= MOUSEEVENTF_LEFTUP;
        if (g_inputState.mouseState.rgbButtons[1] & 0x80 && !(inputState.mouseState.rgbButtons[1] & 0x80))
            input.mi.dwFlags |= MOUSEEVENTF_RIGHTUP;
        if (g_inputState.mouseState.rgbButtons[2] & 0x80 && !(inputState.mouseState.rgbButtons[2] & 0x80))
            input.mi.dwFlags |= MOUSEEVENTF_MIDDLEUP;
        SendInput(1, &input, sizeof(INPUT));
    }
}

int main()
{
    // 初始化窗口
    HWND hWnd = GetDesktopWindow();
    ShowWindow(hWnd, SW_SHOW);
    UpdateWindow(hWnd);

    // 初始化DirectInput设备
    InitDirectInput(hWnd);

    // 打开记录文件
    std::ofstream ofs("input.dat", std::ios::binary);

    // 循环获取输入状态并记录到文件中
    MSG msg;
    while (true)
    {
        while (PeekMessage(&msg, nullptr, 0, 0, PM_REMOVE))
        {
            if (msg.message == WM_QUIT)
                break;
            TranslateMessage(&msg);
            DispatchMessage(&msg);
        }

        GetKeyboardState();
        GetMouseState();
        RecordInputState(g_inputState, ofs);
        Sleep(1);
    }

    // 关闭记录文件
    ofs.close();

    // 释放DirectInput设备
    ReleaseDirectInput();

    return 0;
}

这个示例程序将记录键盘和鼠标的输入状态，并将它们写入名为“input.dat”的二进制文件中。你可以使用sendinput函数来执行回放，如下所示：

#include <Windows.h>
#include <fstream>

// 定义键盘和鼠标的输入状态
struct InputState
{
    BYTE keyboardState[256];
    DIMOUSESTATE mouseState;
};

int main()
{
    // 打开记录文件
    std::ifstream ifs("input.dat", std::ios::binary);

    // 循环读取输入状态并回放
    InputState inputState;
    while (ifs.read((char*)&inputState, sizeof(inputState)))
    {
        Sleep(1);
        ReplayInputState(inputState);
    }

    // 关闭记录文件
    ifs.close();

    return 0;
}

这个示例程序将从名为“input.dat”的二进制文件中读取键盘和鼠标的输入状态，并使用ReplayInputState函数来执行回放。注意，回放过程中需要使用Sleep函数来模拟输入的时间间隔，否则回放速度可能会非常快
