我想几乎发送这样的命令:

when keypress=="a"                   #if entered key is "a"
    send {ALT+TAB}                   # send ALT and TAB simultaneously
    sleep(2)                         #wait for 2 sec
    send {"I love my Country",0.1}   #send all strings at 0.1 sec wait
    key_down("BACKSPACE",1)          #hold down backspace key for 1 sec
    send{ALT+F4}                     #send ALT and F4 simultaneously

对于所有或特定应用程序,opengl 游戏也是如此。

我试过 SendKeys.py 但没有同时输入功能,也没有 key_down 方法来发送按住键的命令。所有建议将不胜感激。

我知道如何使用 ctypes 来做到这一点。例如对于 Alt-Tab(我知道这是很多样板代码):

import ctypes
import time

SendInput = ctypes.windll.user32.SendInput

PUL = ctypes.POINTER(ctypes.c_ulong)
class KeyBdInput(ctypes.Structure):
    _fields_ = [("wVk", ctypes.c_ushort),
                ("wScan", ctypes.c_ushort),
                ("dwFlags", ctypes.c_ulong),
                ("time", ctypes.c_ulong),
                ("dwExtraInfo", PUL)]

class HardwareInput(ctypes.Structure):
    _fields_ = [("uMsg", ctypes.c_ulong),
                ("wParamL", ctypes.c_short),
                ("wParamH", ctypes.c_ushort)]

class MouseInput(ctypes.Structure):
    _fields_ = [("dx", ctypes.c_long),
                ("dy", ctypes.c_long),
                ("mouseData", ctypes.c_ulong),
                ("dwFlags", ctypes.c_ulong),
                ("time",ctypes.c_ulong),
                ("dwExtraInfo", PUL)]

class Input_I(ctypes.Union):
    _fields_ = [("ki", KeyBdInput),
                 ("mi", MouseInput),
                 ("hi", HardwareInput)]

class Input(ctypes.Structure):
    _fields_ = [("type", ctypes.c_ulong),
                ("ii", Input_I)]

def PressKey(hexKeyCode):

    extra = ctypes.c_ulong(0)
    ii_ = Input_I()
    ii_.ki = KeyBdInput( hexKeyCode, 0x48, 0, 0, ctypes.pointer(extra) )
    x = Input( ctypes.c_ulong(1), ii_ )
    ctypes.windll.user32.SendInput(1, ctypes.pointer(x), ctypes.sizeof(x))

def ReleaseKey(hexKeyCode):

    extra = ctypes.c_ulong(0)
    ii_ = Input_I()
    ii_.ki = KeyBdInput( hexKeyCode, 0x48, 0x0002, 0, ctypes.pointer(extra) )
    x = Input( ctypes.c_ulong(1), ii_ )
    ctypes.windll.user32.SendInput(1, ctypes.pointer(x), ctypes.sizeof(x))


def PressAltTab():

    PressKey(0x012) #Alt
    PressKey(0x09) #Tab

    time.sleep(2) #optional : if you want to see the atl-tab overlay

    ReleaseKey(0x09) #~Tab
    ReleaseKey(0x012) #~Alt


if __name__ =="__main__":

     PressAltTab()

现代版本将使用 Unicode :

KEYEVENTF_UNICODE = 0x0004 KEYEVENTF_KEYUP = 0x0002

def PressKey(KeyUnicode):

    extra = ctypes.c_ulong(0)
    ii_ = Input_I()
    ii_.ki = KeyBdInput( 0, KeyUnicode, KEYEVENTF_UNICODE, 0, ctypes.pointer(extra) )
    x = Input( ctypes.c_ulong(1), ii_ )
    ctypes.windll.user32.SendInput(1, ctypes.pointer(x), ctypes.sizeof(x))

def ReleaseKey(KeyUnicode):

    extra = ctypes.c_ulong(0)
    ii_ = Input_I()
    ii_.ki = KeyBdInput( 0, KeyUnicode, KEYEVENTF_UNICODE|KEYEVENTF_KEYUP, 0, ctypes.pointer(extra) )
    x = Input( ctypes.c_ulong(1), ii_ )
    ctypes.windll.user32.SendInput(1, ctypes.pointer(x), ctypes.sizeof(x))


def PressAltTab():

    PressKey(unichr(0x12)) #Alt
    PressKey(unichr(0x09)) #Tab

    time.sleep(2) #optional : if you want to see the atl-tab overlay

    ReleaseKey(unichr(0x09)) #~Tab
    ReleaseKey(unichr(0x12)) #~Alt


if __name__ =="__main__":

     PressAltTab()

为楼上的回答做一些补充。

接下来是虚拟键码。

vk = VK()

所以你可以像这样使用它:


from ctypes_key import PressKey, ReleaseKey
from my_time import vk
import time as tt

# press any ch
def down_up(ch, t = 0.5):
    ch = vk.conv_ord(ch)
    PressKey(ch)
    tt.sleep(t)
    ReleaseKey(ch)

def main():
    ch = 'a'        # KeyDown and KeyUp
    tt.sleep(1)
    down_up(ch)

    # select all
    tt.sleep(1)
    PressKey(vk.ctrl)
    PressKey(vk.a)
    tt.sleep(0.5)
    ReleaseKey(vk.a)
    ReleaseKey(vk.ctrl)

    return 1


if __name__ == '__main__':
    main()
