python - 如何在 selenium 中使用 chrome webdriver 在 python 中下载文件？

Question

基于帖子here和 here我正在尝试在 selenium 中使用 chrome webdriver 来下载文件。这是到目前为止的代码

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument("--disable-extensions")
chrome_options.add_experimental_option("profile.default_content_settings.popups", 0)
chrome_options.add_experimental_option("download.prompt_for_download", "false")
chrome_options.add_experimental_option("download.default_directory", "/tmp")

driver = webdriver.Chrome(chrome_options=chrome_options)

但这会导致以下错误:

WebDriverException: Message: unknown error: cannot parse capability: chromeOptions
from unknown error: unrecognized chrome option: download.default_directory
  (Driver info: chromedriver=2.24.417424 (c5c5ea873213ee72e3d0929b47482681555340c3),platform=Linux 4.10.0-37-generic x86_64)

那么如何解决这个问题呢？我必须使用这种“能力”吗？如果是这样，具体如何？

试试这个。在windows上执行

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_experimental_option("prefs", {
  "download.default_directory": r"C:\Users\xxx\downloads\Test",
  "download.prompt_for_download": False,
  "download.directory_upgrade": True,
  "safebrowsing.enabled": True
})
