python-3.x - Selenium chrome --headless 如何工作？

问题描述

伙计们！与 selenium 一起使用的 chromedriver 中的基本模式和 --headless 模式之间的真正区别是什么？我问是因为我试图在 adidas.com 上跟踪一些价格，当我设置我的驱动程序时：

chrome_options = webdriver.ChromeOptions()
browser = webdriver.Chrome(ChromeDriverManager().install(), options=chrome_options)
browser.get(url)

浏览器在我的电脑上打开，一切正常。

但是当我试图执行下面的代码时：

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--headless")
browser = webdriver.Chrome(ChromeDriverManager().install(), options=chrome_options)
browser.get(url)

回应是：

'<html lang="en"><head>\n    <meta charset="utf-8">\n    <meta name="viewport"
content="width=device-width, initial-scale = 1.0, maximum-scale=1.0, user- 
scalable=no">\n    <title>adidas</title>\n\n    <link 
href="/WAFfailoverassets/style.css" rel="stylesheet">\n</head>\n<body>\n\n<main 
class="content-wrapper">\n    <header class="top">\n        <div 
class="logo">adidas</div>\n        <span 
id="ctl00_mainContentPlaceHolder_lblInvalidRequest">\n<br> Reference Error: 
18.6c85655f.1629459608.2c05a32c </span>\n        <h1 class="title">Unfortunately we 
are unable to give you access to our site at this time. </h1>\n        <p>A security

</header>\n\n    <div class="columns">\n\n        <section class="column column-1">\n

this to protect customers and to give everyone a fair chance of getting the sneakers.

you onto the site.</p>\n        </section>\n\n        <section class="column column- 
2">\n            <h3>How can I resolve this?</h3>\n            <p>Please try 
refreshing or accessing our website from a different browser or another device. You 
could also check if there are any scripts, like ad blockers, running in your browser 
and disable them. </p>\n            <p>If this does not help, the issue might be 
caused by malware. If you\'re on a personal connection you can run an anti-virus scan 
on your device to make sure it\'s not affected by malware. If you\'re on a shared 
network, you could ask the system administrator to run a scan looking for 
misconfigured or infected devices across the network.</p>\n        </section>\n\n    
</div>\n\n    <small class="error">HTTP 403 - 
Forbidden</small>\n\n</main>\n\n\n\n</body></html>'

所以问题是网站如何检测它的代码是否真的呈现，如果我想在服务器上运行我的代码，我该如何处理？
