pywin32 + PyQt5
需要先 pip 安装 pywin32、PyQt5 ，相关依赖 pip 会自动安装。
pip install pywin32
pip install PyQt5下面这种方式比较强悍，可以根据活跃窗口的 title 名称，自动找到对应的窗口然后进行截图。
import sysimport win32gui
from PyQt5.QtWidgets import QApplicationclass Window(object):def __init__(self, hwnd):self.hwnd = hwndself.window_title = win32gui.GetWindowText(hwnd)self.window_class_name = win32gui.GetClassName(hwnd)self.window_rect = win32gui.GetWindowRect(hwnd)def __str__(self):return f"hwnd: {self.hwnd}, window_title: {self.window_title}, window_class_name: {self.window_class_name}, window_rect: {self.window_rect}"class WindowsHandler(object):def __init__(self):self.current_windows = []self._init_all_windows()def _init_all_windows(self):win32gui.EnumWindows(self._get_window, 0)def _get_window(self, hwnd, nouse):if win32gui.IsWindow(hwnd) and win32gui.IsWindowEnabled(hwnd) and win32gui.IsWindowVisible(hwnd):self.current_windows.append(Window(hwnd))def get_windows_by_title(self, title_name):return [window for window in self.current_windows if title_name in window.window_title]def screenshot_window_byPyQt(self, window: Window, img_save_path):app = QApplication(sys.argv)screen = QApplication.primaryScreen()img = screen.grabWindow(window.hwnd).toImage()img.save(img_save_path)if __name__ == '__main__':wh = WindowsHandler()windows = wh.get_windows_by_title("Looooking")if windows:window = windows[0]print(window)wh.screenshot_window_byPyQt(window, "./test.png")
pyautogui
安装好 pyautogui 库就好了，这个库主要用于鼠标键盘模拟操作，当然屏幕截图也是手到擒来。
import pyautoguiif __name__ == '__main__':screenshot = pyautogui.screenshot() # 截全屏screenshot.save("full.png")screenshot = pyautogui.screenshot(region=(100, 100, 500, 500)) # 截图指定区域部分screenshot.save("part.png")
selenium
chromedriver（114 及以前的旧版）: CNPM Binaries Mirror
chromedriver （115 及之后的新版）：百度网盘链接：https://pan.baidu.com/s/1yk6js4yz_NBzXAp71ZIOzA?pwd=2vo3提取码：2vo3
还可以使用 selenium 对打开的浏览器窗口截图。
