Chrome 57更改了设置...使用此功能可停用Chrome PDF查看器:

//To disable PDF viewer plugins with Chrome 57
chromePrefs.put("plugins.always_open_pdf_externally", true);

在Python中,使用:`chrome_options = webdriver.ChromeOptions(); chrome_options.add_experimental_option("prefs",{"download.prompt_for_download":False,"plugins.always_open_pdf_externally":True})`
