Selenium Webdriver in Python - files download directory change in Chrome preferences
提问by Parzival
I'm using Selenium Webdriver (in Python) to automate the downloading of thousands of files. I want to set Chrome's download folder programmatically. After reading this, I tried this:
我正在使用 Selenium Webdriver（在 Python 中）来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。看完这个，我尝试这样做：
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)
No good. Downloads still go to the default download folder ("/Users/thiagomarzagao/Downloads").
不好。下载仍会转到默认下载文件夹（“/Users/thiagomarzagao/Downloads”）。
Any thoughts?
有什么想法吗？

我想你也需要
"directory_upgrade": true
Using the dictionary directly in a Chrome 'Prefrences' file, on a local windows install of chrome Version 28.0.1500.95 m, with the following download options:
在 Chrome 版本 28.0.1500.95 m 的本地 Windows 安装上直接在 Chrome 的“首选项”文件中使用字典，具有以下下载选项：
"download": {
"default_directory": "C:\Users\rdub\Desktop",
"extensions_to_open": ""
},
I get the default location, versus the desktop. When I change it to this:
我得到了默认位置，而不是桌面。当我将其更改为：
"download": {
"default_directory": "C:\Users\rdub\Desktop",
"directory_upgrade": true,
"extensions_to_open": ""
},
I get the desktop location.
我得到桌面位置。
Try the following:
请尝试以下操作：
desired_caps = {'prefs': {'download': {'default_directory': '/Users/thiagomarzagao/Desktop/downloaded_files/', "directory_upgrade": true, "extensions_to_open": ""}}}

The following worked for me:
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)

I try all the anwsers in this question, but it doesn't work for my in Ubuntu 16.10. So I add the change with os.environ for the variable XDG_DOWNLOAD_DIR. Which doesn't work, but I think that it helps.
我尝试了这个问题中的所有答案，但它不适用于我的Ubuntu 16.10。因此，我使用 os.environ 为变量XDG_DOWNLOAD_DIR添加了更改。这不起作用，但我认为它有帮助。
That is:
那是：
os.environ['XDG_DOWNLOAD_DIR'] = default_download_directory
The really change that works perfectly for meis setup the download folder via the command xdg-user-dirs-updatethrough a system call in execution time:
真正适合我的更改是通过执行时的系统调用通过命令xdg-user-dirs-update设置下载文件夹：
os.system("xdg-user-dirs-update --set DOWNLOAD " + default_download_directory)
So, all my code related to setup the download dir is the following:
因此，我所有与设置下载目录相关的代码如下：
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)

If anyone is still having trouble and the above solutions didn't work, I found adding a following slash ('\') to my download path.
如果有人仍然遇到问题并且上述解决方案不起作用，我发现在我的下载路径中添加了以下斜杠 ('\')。
Mine looked like this:
我的看起来像这样：
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)

For anybody still wondering why their implementation doesn't work: You have to put the FULL PATH for it to work. e.g. '/Users/you/dlfolder' won't work, while 'C:/Users/you/dlfolder' will.
对于仍然想知道为什么他们的实现不起作用的人：您必须设置完整路径才能使其工作。例如，“/Users/you/dlfolder”将不起作用，而“C:/Users/you/dlfolder”将起作用。
