使用ChromeDriver和Selenium禁用下载_python selenium 谷歌浏览器禁止下载文件

Preferences for ChromeDriver是一个实验性的选项。

可以显式设置下载首选项。

from selenium import webdriver

options = webdriver.ChromeOptions()

prefs = {
    "download.open_pdf_in_system_reader": False,
    "download.prompt_for_download": True,
    "plugins.always_open_pdf_externally": False
}
options.add_experimental_option(
    "prefs", prefs
)
driver = webdriver.Chrome(
    options=options
)
driver.get(
"https://www.hudoig.gov/sites/default/files/documents/2016-FW-1007.pdf"
)
driver.close()

或者，可以将下载位置设置为将文档作为/dev/null写入虚拟设备文件，从而有效地将其丢弃。

prefs = {
    "download.open_pdf_in_system_reader": False,
    "download.prompt_for_download": True,
    "download.default_directory": "/dev/null",
    "plugins.always_open_pdf_externally": False
}
options.add_experimental_option(
    "prefs", prefs
)
