我想通过异步通信运行截图功能-解网

问：

我想创建一个站点，在输入URL时输出URL目标和SSL证书的到期日期的屏幕截图。屏幕截图是使用 selenium 完成的。但是，使用硒的屏幕截图需要一些时间，因此我想在不等待屏幕截图结果的情况下显示站点结果，并在拍摄后立即输出屏幕截图。

selenium_function.py

# selenium 4
from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.common.by import By
import os 
import re
import sys


if len(sys.argv) != 2:
    print("argument isnt two")

else:
    url = sys.argv[1]
    
    #headless
    options = webdriver.ChromeOptions()
    options.add_argument('--headless')
    options.add_argument('--hide-scrollbars')
    options.add_argument('--incognito')

    driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()),options=options)

    driver.implicitly_wait(10) # seconds

    driver.get(url)

    sanitizedurl = re.sub(r'[\\/:*?"<>|]+','',url)

    driver.get_screenshot_as_file(os.getcwd() + "\\ss\\" + sanitizedurl + "_small" + "_screenshot" + ".png")

    width = driver.execute_script("return document.body.scrollWidth;")
    height = driver.execute_script("return document.body.scrollHeight;")
    driver.set_window_size(width,height)

    driver.get_screenshot_as_file(os.getcwd() + "\\ss\\" + sanitizedurl + "_big" + "_screenshot" + ".png")

    print(sanitizedurl)

测试.php

<?php

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $url = $_POST['url'];
    $url = urldecode($url);
    $pythonScript = "selenium_function.py";

    $command = "C:/Users/~~~~~~~/Python311/python.exe $pythonScript $url";
    $output = exec($command);

    $output_sanitizedurl = mb_convert_encoding($output, "UTF-8", "auto");

    $date = "2024/01/01";
}
?>

<head>
    <title>URL_SCREENSHOT</title>
</head>
<body>
    <h1>URL_SCREENSHOT</h1>

    <form method="post" action="test.php">
        <label for="url">Input URL:</label>
        <input type="text" name="url" id="url" required>
        <input type="submit" value="take a screenshot">
    </form>
    <h2>SSL_DATE</h2>
    <?php if(isset($date)){echo $date;}?>
    <h3>Screenshot</h3>
        <a href="./ss/<?php echo $output_sanitizedurl?>_big_screenshot.png" >
            <img src="./ss/<?php echo $output_sanitizedurl?>_small_screenshot.png" width="100%">
        </a>
</body>
</html>

我一直在尝试进行异步处理，并研究了 async/await 并尝试了它，但它没有按预期工作。我还想知道异步处理是否是我现在尝试做的事情的正确解决方案。请帮忙。

php python-3.x selenium-webdriver 异步 async-await
