如何为Python消息Spam程序添加终止循环的热键（pyautogui/keyboard）

我开发了一款消息Spam程序，需要添加一个热键来终止循环。尝试使用failsafe、while True等待按键、add_hotkey等方法，但均未生效，请问该如何实现？

原示例代码 #

import codecs
import sys
import time
from pathlib import Path
import colorama
import keyboard
from Tools.i18n.makelocalealias import pprint
from art import text2art
import yaml
import pyautogui as pag
pag.FAILSAFE = True
colorama.init()

# 激活热键
hotkey = "9"
# 打开聊天热键
open_hotkey = "shift+t"
# 启用打开聊天热键
enable_open_chat_hotkey = True
# 发送消息热键
send_msg_hotkey = "enter"
# 字符输入间隔
character_interval = 0
# 消息发送间隔
interval = 0.15

close_hotkey = "H+J"


can_run = True

def initConfig():
    global hotkey, open_hotkey, enable_open_chat_hotkey, send_msg_hotkey, character_interval, interval, close_hotkey
    if Path("config.yml").is_file():
        with codecs.open('config.yml', encoding="UTF-8") as f:
            loadedConfig = yaml.safe_load(f)
            hotkey = loadedConfig['hotkey']
            open_hotkey = loadedConfig['open_hotkey']
            enable_open_chat_hotkey = loadedConfig['enable_open_chat_hotkey']
            send_msg_hotkey = loadedConfig['send_msg_hotkey']
            character_interval = loadedConfig['character_interval']
            interval = loadedConfig['interval']
            close_hotkey = loadedConfig['close_hotkey']

            print(
                f"激活热键: {hotkey}\n"
                f"打开聊天热键（若启用）: {open_hotkey}\n"
                f"是否启用游戏内打开聊天热键?: " + ("否", "是")[enable_open_chat_hotkey] + "\n"
                f"字符输入间隔: {character_interval}\n"
                f"消息发送间隔（建议保留0.2，过低Dota无法承受）: {interval}\n"
                f"停止热键: {close_hotkey}\n"
            )

def main():
    print(text2art("1000-7      SCRIPT", "standart"))

    print(
        "您好，当前程序设置如下：\n")
    initConfig()

    keyboard.add_hotkey(hotkey, lambda: print_1000_7())


    keyboard.wait()

def invert_run():
    global can_run
    can_run = not can_run
    print(f"运行状态已切换: {'继续' if can_run else '暂停'}")

def print_1000_7():
    global can_run
    can_run = True  # 启动刷屏时重置运行状态
    print("What is 1000-7?")
    if enable_open_chat_hotkey:
        keyboard.press_and_release(open_hotkey)
        keyboard.press_and_release('ctrl+a')
        keyboard.press_and_release('backspace')
        time.sleep(interval)

    keyboard.write("What is 1000-7?", character_interval)
    keyboard.press_and_release(send_msg_hotkey)

    keyboard.press_and_release('ctrl+a')
    keyboard.press_and_release('backspace')
    keyboard.press_and_release('F9')
    keyboard.write("What is 1000-7?")
    keyboard.press_and_release(send_msg_hotkey)
    if enable_open_chat_hotkey:
        keyboard.press_and_release(open_hotkey)

    for i in range(5):
        if not can_run:
            return
        print(5 - i)
        if enable_open_chat_hotkey:
            keyboard.press_and_release(open_hotkey)
            keyboard.press_and_release('ctrl+a')
            keyboard.press_and_release('backspace')
            time.sleep(interval)
        keyboard.write(str(5-i), character_interval)
        keyboard.press_and_release(send_msg_hotkey)
        time.sleep(1)

    x = 1000
    while x > 0:
        if not can_run:
            return
        var = x - 7
        if enable_open_chat_hotkey:
            keyboard.press_and_release(open_hotkey)
            keyboard.press_and_release('ctrl+a')
            keyboard.press_and_release('backspace')
            time.sleep(interval)
        keyboard.write(f"{x} - 7 = {var}", character_interval)
        x = var
        time.sleep(interval)
        keyboard.press_and_release(send_msg_hotkey)


if __name__ == '__main__':
    main()
    while True:
        keyboard.wait(close_hotkey)
        invert_run()

问题分析 #

原代码的核心问题：

• main()函数中的keyboard.wait()会阻塞主线程，导致主入口处的终止热键监听循环完全无法执行。
• 终止热键的注册时机错误，没有在程序启动阶段完成监听，导致热键触发无响应。

    # 注册激活热键和终止热键
    keyboard.add_hotkey(hotkey, print_1000_7)
    keyboard.add_hotkey(close_hotkey, invert_run)

    print("程序已启动，按激活热键开始刷屏，按终止热键暂停/继续")
    keyboard.wait()  # 保持程序运行，监听热键

if __name__ == '__main__':
    main()

关键修改说明 #

• 调整热键注册时机：将终止热键close_hotkey的注册移到main()函数内，和激活热键一起完成注册，确保程序启动后立即监听热键。
• 移除冗余阻塞代码：删除主入口处的while True循环，避免和main()中的keyboard.wait()冲突，保证主线程专注于热键监听。
• 重置运行状态：在print_1000_7()函数开头重置can_run为True，确保每次启动刷屏流程时都处于可运行状态。
• 增强状态反馈：在终止循环时添加打印提示，便于确认热键是否生效。
