keybd_event模拟键盘按键，mouse_event怎么用

从 模仿UP主，用Python实现一个弹幕控制的直播间！ - 蛮三刀酱 - 博客园 (cnblogs.com) 知道了 PyAutoGUI:

* Moving the mouse and clicking in the windows of other applications.
* Sending keystrokes to applications (for example, to fill out forms).
* Take screenshots, and given an image (for example, of a button or checkbox), and find it on the screen.
* Locate an application's window, and move, resize, maximize, minimize, or close it (Windows-only, currently).
* Display alert and message boxes.

Much of this code is based on information gathered from Paul Barton's PyKeyboard in PyUserInput from 2013, itself derived from Akkana Peck's pykey in 2008 ( http://www.shallowsky.com/software/crikey/pykey-0.1 ), itself derived from her "Crikey" lib. 久经考验喽，Windows, Linux, OS X都支持唷。

看它的源码可知道keybd_event的用法，例如：

def _keyDown(key):
    """Performs a keyboard key press without the release. This will put that
    key in a held down state.

    NOTE: For some reason, this does not seem to cause key repeats like would
    happen if a keyboard key was held down on a text field.

    Args:
      key (str): The key to be pressed down. The valid names are listed in
      pyautogui.KEY_NAMES.

    Returns:
      None
    """
    if key not in keyboardMapping or keyboardMapping[key] is None:
        return

    needsShift = pyautogui.isShiftCharacter(key)

    """
    # OLD CODE: The new code relies on having all keys be loaded in keyboardMapping from the start.
    if key in keyboardMapping.keys():
        vkCode = keyboardMapping[key]
    elif len(key) == 1:
        # note: I could use this case to update keyboardMapping to cache the VkKeyScan results, but I've decided not to just to make any possible bugs easier to reproduce.
        vkCode = ctypes.windll.user32.VkKeyScanW(ctypes.wintypes.WCHAR(key))
        if vkCode == -1:
            raise ValueError('There is no VK code for key "%s"' % (key))
        if vkCode > 0x100: # the vk code will be > 0x100 if it needs shift
            vkCode -= 0x100
            needsShift = True
    """
    mods, vkCode = divmod(keyboardMapping[key], 0x100)

    for apply_mod, vk_mod in [(mods & 4, 0x12), (mods & 2, 0x11),
        (mods & 1 or needsShift, 0x10)]: #HANKAKU not supported! mods & 8
        if apply_mod:
            ctypes.windll.user32.keybd_event(vk_mod, 0, KEYEVENTF_KEYDOWN, 0) #
    ctypes.windll.user32.keybd_event(vkCode, 0, KEYEVENTF_KEYDOWN, 0)
    for apply_mod, vk_mod in [(mods & 1 or needsShift, 0x10), (mods & 2, 0x11),
        (mods & 4, 0x12)]: #HANKAKU not supported! mods & 8
        if apply_mod:
            ctypes.windll.user32.keybd_event(vk_mod, 0, KEYEVENTF_KEYUP, 0) #

虽然它是python写的，但对VC和C#程序员很有参考价值。我是做了个半拉子不大好使。

我从github下载了源码放在博客园里了：https://files.cnblogs.com/files/blogs/714801/pyautogui-master.zip
