Python块键盘/鼠标输入

Question

我目前正在尝试写一个简短的脚本，它将在用户观看时打开youtube链接，不能干预。我已经设法打开，慢慢插入链接一个字母，现在正试图阻止用户的输入。我尝试过使用ctypes导入来阻止所有输入，运行脚本，然后再取消阻塞，但它无论如何不会阻止输入。我刚收到我的RuntimeError信息。如何修复它，这样输入就会被阻塞？提前感谢！这是代码：

import subprocess
import pyautogui
import time
import ctypes
from ctypes import wintypes

BlockInput = ctypes.windll.user32.BlockInput
BlockInput.argtypes = [wintypes.BOOL]
BlockInput.restype = wintypes.BOOL

blocked = BlockInput(True)

if blocked:
    try:
        subprocess.Popen(["C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe",])
        time.sleep(3)
        pyautogui.write('www.youtube.com/watch?v=DLzxrzFCyOs', interval= 0.5)
        pyautogui.hotkey('enter')
    finally:
        unblocked = BlockInput(False)
else:
    raise RuntimeError('Input is already blocked by another thread')

您可以使用键盘模块阻止所有键盘输入和鼠标模块不断移动鼠标，防止用户移动它。

有关更多细节，请参见这些链接：

这会阻塞键盘上的所有键( 150足够大以确保所有键都被阻塞)。

#### Blocking Keyboard ####
import keyboard

#blocks all keys of keyboard
for i in range(150):
    keyboard.block_key(i)

这有效地阻止鼠标移动，不断移动鼠标定位(1,0)。

#### Blocking Mouse-movement ####
import threading
import mouse
import time

global executing
executing = True

def move_mouse():
    #until executing is False, move mouse to (1,0)
    global executing
    while executing:
        mouse.move(1,0, absolute=True, duration=0)

def stop_infinite_mouse_control():
    #stops infinite control of mouse after 10 seconds if program fails to execute
    global executing
    time.sleep(10)
    executing = False

threading.Thread(target=move_mouse).start()

threading.Thread(target=stop_infinite_mouse_control).start()
#^failsafe^

然后这里的原始代码( if语句和try/catch块不再必要)。

#### opening the video ####
import subprocess
import pyautogui
import time

subprocess.Popen(["C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe",])
time.sleep(3)
pyautogui.write('www.youtube.com/watch?v=DLzxrzFCyOs', interval = 0.5)
pyautogui.hotkey('enter')


#### stops moving mouse to (1,0) after video has been opened
executing = False

只是几个音符：

1. 鼠标移动很难从程序外部停止(当程序执行时，基本上不可能关闭程序，特别是在键盘也被阻塞的情况下)，这就是为什么我在10秒后将鼠标停止移动到(1,0)中的原因。
2. ( opened )控件--Alt-Delete允许打开任务管理器，然后可以强制执行。
3. 这并不能阻止用户单击鼠标，这有时会阻止YouTube链接被完整键入(即可以打开一个新的选项卡)

您可以这样做来阻止键盘和鼠标的输入。

    from ctypes import windll
    from time import sleep
    
    windll.user32.BlockInput(True) #this will block the keyboard input
    sleep(15) #input will be blocked for 15 seconds
    windll.user32.BlockInput(False) #now the keyboard will be unblocked

这里有一个阻止键盘和鼠标输入的函数。您可以向blockMouseAndKeys函数传递一个数字以调整超时时间：

import os
import time
import pyautogui
from threading import Thread
from keyboard import block_key

def blockMouseAndKeys(timeout=5):
    global blocking
    blockStartTime = time.time()
    pyautogui.FAILSAFE = False
    blocking = True
    try: float(timeout)
    except: timeout = 5

    def blockKeys(timeout):
        global blocking
        while blocking:
            if timeout:
                if time.time()-blockStartTime > timeout:
                    print(f'Keyboard block timed out after {timeout}s.')
                    return
            for i in range(150):
                try: block_key(i)
                except: pass
    def blockMouse(timeout):
        global blocking
        while blocking:
            def resetMouse(): pyautogui.moveTo(5,5)
            Thread(target=resetMouse).start()
            if timeout:
                if time.time()-blockStartTime > timeout:
                    print(f'Mouse block timed out after {timeout}s.')
                    return
    def blockTimeout(timeout):
        global blocking
        time.sleep(timeout)
        blocking = False
        pyautogui.FAILSAFE = False
        print('Done blocking inputs!')

    print('Blocking inputs...')
    Thread(target=blockKeys, args=[timeout]).start()
    Thread(target=blockMouse, args=[timeout]).start()
    Thread(target=blockTimeout, args=[timeout]).start()


blockMouseAndKeys(timeout=10)
os.startfile('https://www.youtube.com/watch?v=DLzxrzFCyOs')
