如何在Chrome中使用Selenium + Python绑定控制文件的下载 [英] How to control the download of files with Selenium + Python bindings in Chrome

问题描述

在哪里可以找到描述可以与Selenium和Chrome网络浏览器一起使用的选项的文档?我想在网络浏览器中打开一个链接(以获取证书)，但不想下载相应的文件(.pdf或.tiff或.jpeg).我在Windows 7笔记本电脑上使用Python 2.7，硒3.0.1和Chrome版本54.0.2840.99(和chromedriver.exe).

Where can I find the documentation that describes the options I can use with Selenium and Chrome web browser? I want to open a link in a web browser (to get credential) but not to download the corresponding file (.pdf or .tiff or .jpeg). I am using Python 2.7, selenium 3.0.1 and Chrome version 54.0.2840.99 (and chromedriver.exe) on Windows 7 Laptop.

# Chrome web browser.
options = webdriver.ChromeOptions()
options.add_argument('--ignore-certificate-errors')  
#options.add_argument('--disable-download-notification') #doesn't seems to work 
#options.add_experimental_option("prefs", {"download.default_directory","C:\Users\xxx\downloads\Test"}) # doesn't work
#options.add_experimental_option("prefs", {"download.prompt_for_download": False}) # doesn't seems to work
#options.add_experimental_option("prefs", {'profile.default_content_settings': {'images': 2}})# this will disable image loading in the browser
options.add_argument("user-agent="+user_agent_profile)
driver_main = webdriver.Chrome(chrome_options=options)

# Opening the web application portail.
driver_main.get("https://my_link")

我找到了很多与此主题相关的讨论，但没有一种解决方案有效.例如:

I found many discussions on this topic but none of the solution works. For example:

add_experimental_option("prefs", {"download.default_directory","C:\Users\xxx\downloads\Test"})

对我不起作用.

相同于:

add_experimental_option("prefs", {"download.prompt_for_download": False})

(我也尝试使用"false").

(I also try with "false").

而:

add_argument("user-agent="+user_agent_profile)

似乎可以正常工作！

我不确定是怎么了

我遇到的问题是，每次我打开带有名称file(1)file(2).... file(99)的链接时，它便开始下载文件，然后从100开始，它将打开一个弹出窗口.另存为".因此，我要么根本不下载文件，要么能够将其移动到回收站"中的特定文件夹中.

The issue I got is that, it starts to download the file each time I open a link with name file(1) file(2) .... file(99) then starting at 100 it opens a popup window "Save As". So I would like to either don't download the file at all or be able to move it in a specific folder in the "Recycle Bin".

如何找到可与add_argument和add_argument一起使用的选项?我试图看一下Chrome://about/，但看不到直接对应.

How do I find which options could be I used with add_argument and add_argument? I tried to look at Chrome://about/ but I couldn't see a direct correspondence.

非常感谢.

干杯.

推荐答案

您为默认目录声明的路径无效.要么转义反斜杠，要么提供文字字符串.

The path you declared for the default directory is invalid. Either escape the back slashes or provide a literal string.

options = webdriver.ChromeOptions()
options.add_experimental_option("prefs", {
  "download.default_directory": r"C:\Users\xxx\downloads\Test",
  "download.prompt_for_download": False,
  "download.directory_upgrade": True,
  "safebrowsing.enabled": True
})
driver = webdriver.Chrome(chrome_options=options)

以下是可用的偏好设置:

Here are the available preferences:
