Flask设计网页截屏远程电脑桌面及切换运行程序界面

news 来源：原创 2025/6/18 14:30:49

有没有一种办法可以让我通过网页就能够实时查看远程电脑的程序运行情况呢？为此，我想到了利用python的Flask制作一个网页，然后通过cpolar，转变成一个互联网的网页，方便随时了解电脑的程序运行情况，比如百度网盘下载多少文件了，python数据处理是否完成等等。

1.flask服务端：

"""from flask import Flask, render_template, send_file
import pyautogui
import os
import timeapp = Flask(__name__)@app.route('/')
def index():return render_template('jp.html')@app.route('/screenshot')
def take_screenshot():screenshot = pyautogui.screenshot()screenshot_path = os.path.join('static', 'screenshot.png')screenshot.save(screenshot_path)return send_file(screenshot_path, mimetype='image/png')@app.route('/switch_window')
def switch_window():pyautogui.hotkey('alt', 'tab')time.sleep(0.5)  # 等待窗口切换完成return 'OK'@app.route('/switch_window1')
def press_win_1():try:pyautogui.keyDown('win')time.sleep(0.1)  # 确保Win键按下pyautogui.press('1')pyautogui.keyUp('win')return 'OK'except Exception as e:print(f"操作失败: {str(e)}")return 'Err'@app.route('/switch_window2')
def press_win_2():try:pyautogui.keyDown('win')time.sleep(0.1)  # 确保Win键按下pyautogui.press('2')pyautogui.keyUp('win')return 'OK'except Exception as e:print(f"操作失败: {str(e)}")return 'Err'@app.route('/switch_window3')
def press_win_3():try:pyautogui.keyDown('win')time.sleep(0.1)  # 确保Win键按下pyautogui.press('3')pyautogui.keyUp('win')return 'OK'except Exception as e:print(f"操作失败: {str(e)}")return 'Err'@app.route('/switch_window4')
def press_win_4():try:pyautogui.keyDown('win')time.sleep(0.1)  # 确保Win键按下pyautogui.press('4')pyautogui.keyUp('win')return 'OK'except Exception as e:print(f"操作失败: {str(e)}")return 'Err'@app.route('/switch_window5')
def press_win_5():try:pyautogui.keyDown('win')time.sleep(0.1)  # 确保Win键按下pyautogui.press('5')pyautogui.keyUp('win')return 'OK'except Exception as e:print(f"操作失败: {str(e)}")return 'Err'@app.route('/switch_windowd')
def press_win_d():try:pyautogui.keyDown('win')time.sleep(0.1)  # 确保Win键按下pyautogui.press('d')pyautogui.keyUp('win')return 'OK'except Exception as e:print(f"操作失败: {str(e)}")return 'Err'@app.route('/switch_ct')
def switch_ct():pyautogui.hotkey('ctrl', 'tab')time.sleep(0.5)  # 等待窗口切换完成return 'OK'@app.route('/switch_csi')
def switch_csi():pyautogui.hotkey('ctrl', 'shift', 'i')time.sleep(0.5)  # 等待窗口切换完成return 'OK'
if __name__ == '__main__':app.run(host='127.0.0.1',debug=True,use_reloader=False)

2.放在templates的网页jp.html

<!DOCTYPE html>
<html>
<head><title>远程桌面控制</title><style>#image-container {width: 800px;height: 600px;border: 1px solid #ccc;margin: 20px auto;}#screenshot-img {max-width: 100%;max-height: 100%;}.button-container {text-align: center;margin: 20px;}button {padding: 10px 20px;margin: 0 10px;font-size: 16px;}</style>
</head>
<body><div class="button-container"><button id="screenshot-btn">截屏</button><button id="switch-btn">切换</button><button id="switch-btn1">Win+1</button><button id="switch-btn2">Win+2</button><button id="switch-btn3">Win+3</button><button id="switch-btn4">Win+4</button><button id="switch-btn5">Win+5</button><button id="switch-btnd">Win+D</button></div><div id="image-container"><img id="screenshot-img" src="" alt="截屏将显示在这里"></div><div class="button-container"><button id="switch-btnct">Ctrl+Tab</button><button id="switch-btncsi">Ctrl+Shift+I</button></div><script>document.getElementById('screenshot-btn').addEventListener('click', function() {fetch('/screenshot').then(response => response.blob()).then(blob => {const img = document.getElementById('screenshot-img');img.src = URL.createObjectURL(blob);});});document.getElementById('switch-btn').addEventListener('click', function() {fetch('/switch_window');});document.getElementById('switch-btn1').addEventListener('click', function() {fetch('/switch_window1');});document.getElementById('switch-btn2').addEventListener('click', function() {fetch('/switch_window2');});document.getElementById('switch-btn3').addEventListener('click', function() {fetch('/switch_window3');});document.getElementById('switch-btn4').addEventListener('click', function() {fetch('/switch_window4');});document.getElementById('switch-btn5').addEventListener('click', function() {fetch('/switch_window5');});document.getElementById('switch-btnd').addEventListener('click', function() {fetch('/switch_windowd');});document.getElementById('switch-btnct').addEventListener('click', function() {fetch('/switch_ct');});document.getElementById('switch-btncsi').addEventListener('click', function() {fetch('/switch_csi');});</script>
</body>
</html>

3.记得新建static文件夹在py程序的同个文件夹中。

4.使用cmd，运行cpolar http 5000

5.python提取cpolar公网地址，也就是4上面显示的网址，发送给你的微信。（用另外一个微信在服务器登录）
