将Chromedriver用于无头浏览器时出现“权限策略标头错误”
在 Selenium 上，我使用的是 chromedriver 版本 89 和我的 chrome 浏览器版本 89.0。也。当我在无头浏览器上运行代码时，出现错误；将 chrome 转换为无头浏览器以测试结果。这是我的脚本-
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
from shutil import which
chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_path = which("chromedriver")
driver = webdriver.Chrome(executable_path=chrome_path, options=chrome_options)
driver.get("https://duckduckgo.com/")
search_input = driver.find_element_by_id("search_form_input_homepage")
search_input.send_keys("My User Agent")
search_input.send_keys(Keys.ENTER)
这是 VSCODE 终端输出，

这是用于阻止 Google 称为联合学习群组 (FLoC) 的新跟踪技术的新标头。
关于 FLoC
DDG 使用标头来阻止 FLoC 跟踪。
DuckDuckGo 宣布计划阻止谷歌的 FLoC
如果您访问任何阻止 FLoC 的网站，您会在 Chrome 开发工具中收到相同的警告。
要在您自己的网站上阻止 Google 的 FLoC，请添加以下标题：
permissions-policy: interest-cohort=()
