Selenium + Python + Chrome:同时 add_experimental_option 并设置 desired_capabilities

Selenium + Python + Chrome: simultaneously add_experimental_option and set desired_capabilities

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:

  1. 它没有弹出窗口 ()。
  2. 它允许我更改下载目录和设置 ()。

尽管这两种解决方案单独使用时都表现出色,但我将它们结合起来的尝试却以灾难性的方式失败了。以下是两个隔离的部分解决方案。在此感谢任何帮助。

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")

您可以将选项转换为所需的功能,并在创建驱动程序期间将其传递给 desired_capabilities 参数:

capabilities.update(options.to_capabilities())

希望对您有所帮助!
