Question

我正在使用Selenium Webdriver（在Python中）自动下载数千个文件。我想以编程方式设置Chrome的下载文件夹。阅读this后，我尝试了这个：

chromepath = '/Users/thiagomarzagao/Desktop/searchcode/chromedriver'
desired_caps = {'prefs': {'download': {'default_directory': '/Users/thiagomarzagao/Desktop/downloaded_files/'}}}
driver = webdriver.Chrome(executable_path = chromepath, desired_capabilities = desired_caps)

不好。下载仍然会转到默认下载文件夹（“/ Users / thiagomarzagao / Downloads”）。

有什么想法吗？

（Python 2.7.5，Selenium 2.2.0，Chromedriver 2.1.210398，Mac OS X 10.6.8）

Answer 1

以下对我有用：

chromeOptions = webdriver.ChromeOptions()
prefs = {"download.default_directory" : "/some/path"}
chromeOptions.add_experimental_option("prefs",prefs)
chromedriver = "path/to/chromedriver.exe"
driver = webdriver.Chrome(executable_path=chromedriver, chrome_options=chromeOptions)

Answer 2

如果有人仍然遇到问题并且上述解决方案无效，我发现在我的下载路径中添加了以下斜杠（＆＃39; \＆＃39;）。

我看起来像这样：

    if browser == 'chrome':
        options = webdriver.ChromeOptions()
        options.add_argument("--start-maximized")
        prefs = {"profile.default_content_settings.popups": 0,
                 "download.default_directory": r"C:\Users\user_dir\Desktop\\", # IMPORTANT - ENDING SLASH V IMPORTANT
                 "directory_upgrade": True}
        options.add_experimental_option("prefs", prefs)
        return webdriver.Chrome(executable_path=Base.chromedriver_dir, chrome_options=options)

Answer 3

我认为你还需要

"directory_upgrade": true

直接在Chrome的“Prefrences”文件中使用字典，在本地Windows版本的Chrome版本28.0.1500.95 m上安装，并提供以下下载选项：

   "download": {
      "default_directory": "C:\\Users\\rdub\\Desktop",
      "extensions_to_open": ""
   },

我获得默认位置，而不是桌面。当我把它更改为：

   "download": {
      "default_directory": "C:\\Users\\rdub\\Desktop",
      "directory_upgrade": true,
      "extensions_to_open": ""
   },

我得到桌面位置。

尝试以下方法：

desired_caps = {'prefs': {'download': {'default_directory': '/Users/thiagomarzagao/Desktop/downloaded_files/', "directory_upgrade": true, "extensions_to_open": ""}}}

Answer 4

我在这个问题中尝试了所有的问题，但是对于我的 Ubuntu 16.10 它不起作用。所以我在os.environ中为变量 XDG_DOWNLOAD_DIR 添加了更改。哪个不起作用，但我认为这有帮助。

那是：

os.environ['XDG_DOWNLOAD_DIR'] = default_download_directory

真正适合我的真正改变是在执行时通过系统调用 xdg-user-dirs-update 命令设置下载文件夹：

os.system("xdg-user-dirs-update --set DOWNLOAD " + default_download_directory)

因此，我设置下载目录的所有代码如下：

import os
from selenium import webdriver

default_download_directory = str(os.path.dirname(os.path.abspath(__file__))) + "/download"

os.environ['XDG_DOWNLOAD_DIR'] = default_download_directory

os.system("xdg-user-dirs-update --set DOWNLOAD " + default_download_directory)

desired_caps = {
    'prefs': {
            'download': {
                'default_directory': str(os.path.dirname(os.path.abspath(__file__))) + "/download", 
                "directory_upgrade": "true", 
                "extensions_to_open": ""
                }
              }
        }

options = webdriver.ChromeOptions() 
options.add_argument("download.default_directory=" + str(os.path.dirname(os.path.abspath(__file__))) + "/download")

browser = webdriver.Chrome(chrome_options=options, desired_capabilities=desired_caps)

Answer 5

将变量传递到“ download.default_directory”

将目录路径存储在变量中，并将变量传递到“ download.default_directory”

注意： .py文件和文件夹“ PDF_Folder”在相同的位置和文件都应下载到文件夹“ PDF_Folder”

exepath = sys.arg[0]
# get the path from the .py file
Dir_path = os.path.dirname(os.path.abspath(exepath))
# get the path of "PDF_Folder" directory
Download_dir = Dir_path+"\\PDF_Folder\\"

preferences = {"download.default_directory": Download_dir , # pass the variable
                   "download.prompt_for_download": False,
                   "directory_upgrade": True,
                   "safebrowsing.enabled": True }
chrome_options.add_experimental_option("prefs", preferences)
driver = webdriver.Chrome(chrome_options=chrome_options,executable_path=r'/pathTo/chromedriver')
driver.get("urlfiletodownload");

Answer 7

对于任何人仍然想知道为什么他们的实现不起作用：你必须把它的全部路径工作。例如'/ Users / you / dlfolder'不起作用，而'C：/ Users / you / dlfolder'会。

Answer 8

这似乎对我有用

chrome_options = webdriver.ChromeOptions()
settings = {
       "recentDestinations": [{
            "id": "Save as PDF",
            "origin": "local",
            "account": "",
        }],
        "selectedDestinationId": "Save as PDF",
        "version": 2,

    }



prefs = {'savefile.default_directory': '/Users/gregreynders/PycharmProjects/Webscraper'}
chrome_options.add_experimental_option('prefs', prefs)
chrome_options.add_argument('--kiosk-printing')


driver = webdriver.Chrome(chrome_options=chrome_options , executable_path="/Applications/chrome/chromedriver" )
driver.get("https://google.com")
driver.execute_script('window.print();')
driver.quit()

使用Python中的Selenium Webdriver设置Chrome首选项
