Downloading a file at a specified location through python and selenium using Chrome driver
提问by Shubham Goyal
I am trying to automatically download some links through selenium's click functionality and I am using a chrome webdriverand python as the programming language. How can I select the download directorythrough the python program so that it does not get downloaded in the default Downloads directory. I found a solution for firefox but there the download dialog keeps popping up every time it clicks on the link which does not happen in Chrome.
我试图通过 selenium 的点击功能自动下载一些链接，我使用chrome webdriver和 python 作为编程语言。如何通过python程序选择下载目录，使其不会在默认下载目录中下载。我找到了 firefox 的解决方案，但每次点击 Chrome 中不会发生的链接时，下载对话框都会不断弹出。

You can create a profile for chrome and define the download location for the tests. Here is an example:
您可以为 chrome 创建配置文件并定义测试的下载位置。下面是一个例子：
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("download.default_directory=C:/Downloads")
driver = webdriver.Chrome(chrome_options=options)

If you are using script only on your local machine then use this solution
如果您仅在本地计算机上使用脚本，请使用此解决方案
Click on Menu -> Setting -> Show advanced settings... -> Downloads
单击菜单 -> 设置 -> 显示高级设置... -> 下载
Now uncheck
现在取消选中
Ask where to save each file before downloading
下载前询问每个文件的保存位置
Hope it will help you :)

I found the accepted solution didn't work, however this slight change did:
我发现接受的解决方案不起作用，但是这个轻微的变化确实：
import webdriver
chrome_options = webdriver.ChromeOptions()
prefs = {'download.default_directory' : '/path/to/dir'}
chrome_options.add_experimental_option('prefs', prefs)
driver = webdriver.Chrome(chrome_options=chrome_options)

If you are using linux distribution
如果您使用的是 linux 发行版
Use this code
使用此代码
prefs = {'download.prompt_for_download': False,
'download.directory_upgrade': True,
'safebrowsing.enabled': False,
'safebrowsing.disable_download_protection': True}
options.add_argument('--headless')
options.add_experimental_option('prefs', prefs)
driver = webdriver.Chrome('chromedriver.exe', chrome_options=options)
driver.command_executor._commands["send_command"] = ("POST", '/session/$sessionId/chromium/send_command')
driver.desired_capabilities['browserName'] = 'ur mum'
params = {'cmd': 'Page.setDownloadBehavior', 'params': {'behavior': 'allow', 'downloadPath': r'C:\chickenbutt'}}
driver.execute("send_command", params)

To provide download directory and chrome's diver executable path use the following code.
要提供下载目录和 chrome 的 diver 可执行路径，请使用以下代码。
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("download.default_directory=C:/Your_Directory")
driver = webdriver.Chrome(options=options ,executable_path='C:/chromedriver')
change the path in your code accordingly.
相应地更改代码中的路径。
