我想使用无头chrome驱动程序下载pdf。当我下载无头chrome的pdf时，一切正常。这是我的驱动程序设置代码的一部分：
options = webdriver.ChromeOptions()
prefs = {'profile.default_content_settings.popups': 0,
"plugins.plugins_list": [{"enabled": False, "name": "Chrome PDF Viewer"}], # Disable Chrome's PDF Viewer
'download.default_directory': 'download_dir' ,
"download.extensions_to_open": "applications/pdf"}
options.add_argument('--headless')
options.add_argument('--disable-gpu')
options.add_argument('"--no-sandbox"')
options.add_argument('--ignore-certificate-errors')
options.add_experimental_option('prefs', prefs)
driver.command_executor._commands["send_command"] = ("POST", '/session/$sessionId/chromium/send_command')
params = {'cmd': 'Page.setDownloadBehavior', 'params': {'behavior': 'allow', 'downloadPath': download_dir}}
driver.execute("send_command", params)
driver.get(url)
try : WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.CLASS_NAME, 'check-pdf')))
finally:
driver.find_element_by_class_name('check-pdf').click()
当我在cmd中运行此文件时出现错误。

我想知道错误消息的含义以及如何解决？
任何想法都会有所帮助！
