python - Selenium + Python + Chrome : simultaneously add_experimental_option and set desired_capabilities

Question

我正在尝试更改 Chrome 驱动程序的设置，以便它允许我执行以下两项操作:

它没有给我一个弹出窗口( as discussed here )。

它允许我更改下载目录和设置( as discussed here )。

尽管这两种解决方案在孤立的情况下都非常有效，但我将它们结合起来的尝试却以灾难性的失败告终。下面是两个孤立的部分解决方案。感谢这里的任何帮助。

代码 1:

### This version save pdf automatically but has automation popup.

from selenium import webdriver
import time


timestr = time.strftime("%Y%m")

options = webdriver.ChromeOptions()

prefs = {
"download.default_directory": r"C:\temp\\"+timestr,
"download.prompt_for_download": False,
"download.directory_upgrade": True,
"plugins.always_open_pdf_externally": True
}

options.add_experimental_option('prefs', prefs)
driver = webdriver.Chrome(executable_path="C://temp//chromedriver.exe",options=options)
driver.get("https://www.tutorialspoint.com/selenium/selenium_tutorial.pdf")

代码 2:

### This version has no automation popup but doesn't save pdf automatically.

from selenium import webdriver
import time


timestr = time.strftime("%Y%m")

capabilities = {
    'browserName': 'chrome',
    'chromeOptions':  {
        'useAutomationExtension': False,
        'forceDevToolsScreenshot': True,
        'args': ['--start-maximized', '--disable-infobars']
    }
}    

driver = webdriver.Chrome(executable_path="C://temp//chromedriver.exe",desired_capabilities=capabilities)
driver.get("https://www.tutorialspoint.com/selenium/selenium_tutorial.pdf")

Answer 1

您可以将选项转换为所需的功能并将其传递给 desired_capabilities创建驱动程序时的参数:

capabilities.update(options.to_capabilities())
