c++ 写个完整的案例：捕获鼠标键盘在全局桌面的操作，写个鼠标键盘hook

在 C++ 中，创建全局桌面级别的鼠标键盘事件钩子（Hook）功能通常需要依赖底层 WinAPI，因为标准库并不直接支持这类操作。以下是一个简单的示例，展示了如何使用 Windows API 来捕获鼠标和键盘事件。请注意，这个示例需要在有权限访问系统级事件的环境下运行，并且通常用于开发者工具或特定的安全控制应用，而不是一般的应用程序。

#include <windows.h>
#include <iostream>

LRESULT CALLBACK MouseProc(int nCode, WPARAM wParam, LPARAM lParam) {
    MOUSEHOOKSTRUCT* mouseStruct = (MOUSEHOOKSTRUCT*)lParam;
    if (nCode >= 0 && wParam == WM_MOUSEMOVE) {
        std::cout << "Mouse moved at (" << mouseStruct->x << ", " << mouseStruct->y << ")" << std::endl;
    }
    return CallNextHookEx(NULL, nCode, wParam, lParam);
}

LRESULT CALLBACK KeyboardProc(int nCode, WPARAM wParam, LPARAM lParam) {
    RAWINPUT* rawInput = (RAWINPUT*)lParam;
    if (nCode >= 0 && wParam == WM_KEYDOWN) {
        char keyChar = ToAscii(rawInput->header.key.vKey, NULL, NULL, &wParam, 0);
        std::cout << "Key down: " << static_cast<char>(keyChar) << std::endl;
    }
    return CallNextHookEx(NULL, nCode, wParam, lParam);
}

int main() {
    HHOOK mouseHook = SetWindowsHookEx(WH_MOUSE_LL, MouseProc, (HINSTANCE)NULL, GetCurrentThreadId());
    if (!mouseHook) {
        std::cerr << "Failed to set mouse hook." << std::endl;
        return 1;
    }

    HHOOK keyboardHook = SetWindowsHookEx(WH_KEYBOARD_LL, KeyboardProc, (HINSTANCE)NULL, GetCurrentThreadId());
    if (!keyboardHook) {
        UnhookWindowsHookEx(mouseHook);
        std::cerr << "Failed to set keyboard hook." << std::endl;
        return 1;
    }

    MSG msg;
    while (GetMessage(&msg, NULL, 0, 0)) {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    UnhookWindowsHookEx(mouseHook);
    UnhookWindowsHookEx(keyboardHook);

    return 0;
}
