如何在 PyWin32 中获取键名并提供其键码？

Question

我正在阅读 PyWin32 docs, and for some reason, the GetKeyNameText function is not there. It's not possible to return the name using GetKeyState or GetKeyboardState 因为很明显，他们 return 只有状态。那么，为什么 GetKeyNameText 不存在，我怎样才能得到键名（从 0 到 256）？

示例：

import win32api

if __name__ == "__main__":

    while True:
        for key in range(256):
            if int(win32api.GetKeyState(key)):
                print(win32api.GetKeyNameText(key)) # Not available in PyWin32.

输出：

Traceback (most recent call last):
  File "main.py", line 32, in <module>
    print(win32api.GetKeyNameText(key)) # Not available in Python.
AttributeError: 'module' object has no attribute 'GetKeyNameText'

对于键，您很可能需要为键创建 VK_CODE 的字典，存在虚拟键代码 here，示例 -

VK_CODE = {8: 'backspace',
 9: 'tab',
 12: 'clear',
 13: 'enter',
 16: 'shift',
 17: 'ctrl',
 18: 'alt',
 19: 'pause',
 20: 'caps_lock',
 27: 'esc',
 32: 'spacebar',
 33: 'page_up',
 34: 'page_down',
 35: 'end',
 36: 'home',
 37: 'left_arrow',
 38: 'up_arrow',
 39: 'right_arrow',
 40: 'down_arrow',
 41: 'select',
 42: 'print',
 43: 'execute',
 44: 'print_screen',
 45: 'ins',

 96: 'numpad_0',

 116: 'F5',
 117: 'F6',
 118: 'F7',
 119: 'F8',
 120: 'F9',
 121: 'F10',
 122: 'F11',
 123: 'F12',
 124: 'F13',
 125: 'F14',
 126: 'F15',
 127: 'F16',
 128: 'F17',

 177: 'previous_track',
 178: 'stop_media',

 180: 'start_mail',
 181: 'select_media',
 182: 'start_application_1',
 183: 'start_application_2',
 186: ';',
 187: '+',
 188: ',',
 189: '-',
 190: '.',
 191: '/',
 192: '`',
 219: '[',
 220: '\',
 221: ']',
 222: "'",
 246: 'attn_key',
 247: 'crsel_key',
 248: 'exsel_key',
 250: 'play_key',
 251: 'zoom_key',
 254: 'clear_key'}

此外，您应该检查 int(win32api.GetKeyState(key)) 与 -127 ，如果键被切换，它可以是 1。
