使用Selenium和python将文件下载到指定位置 [英] Downloading file to specified location with Selenium and python

问题描述

好的，到目前为止，我已经将我的程序转到了我想从中下载链接并选择它的网站，然后会出现 Firefox 对话框，但我不知道该怎么做.我想将此文件保存到我桌面上的一个文件夹中.我正在使用它进行夜间构建，所以我需要它来工作.请帮忙.

Ok so far i have my programing going to the website i want to download link from and selecting it, then the firefox dialogue box shows up and i don't know what to do. i want to save this file to a folder on my desktop. I am using this for a nightly build so i need this to work. Please help.

这是我从网站上获取下载链接的代码:

Here is my code that grabs the download link from the website:

driver = web driver.Firefox()
driver.implicitly_wait(5)
driver.get("Name of web site I'm grabbing from")
driver.find_element_by_xpath("//a[contains(text(), 'DEV.tgz')]".click()

推荐答案

你需要让 Firefox 自动保存这个特定的文件类型.

You need to make Firefox save this particular file type automatically.

这可以通过设置 browser.helperApps.neverAsk.saveToDisk 首选项来实现:

This can be achieved by setting browser.helperApps.neverAsk.saveToDisk preference:

from selenium import webdriver

profile = webdriver.FirefoxProfile()
profile.set_preference("browser.download.folderList", 2)
profile.set_preference("browser.download.manager.showWhenStarting", False)
profile.set_preference("browser.download.dir", 'PATH TO DESKTOP')
profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/x-gzip")

driver = webdriver.Firefox(firefox_profile=profile)
driver.get("Name of web site I'm grabbing from")
driver.find_element_by_xpath("//a[contains(text(), 'DEV.tgz')]").click()

更多解释:

• browser.download.folderList 告诉它不要使用默认的 Downloads 目录
• browser.download.manager.showWhenStarting 轮流显示下载进度
• browser.download.dir 设置下载目录
• browser.helperApps.neverAsk.saveToDisk 告诉 Firefox 自动下载所选 mime-types
的文件

• browser.download.folderList tells it not to use default Downloads directory
• browser.download.manager.showWhenStarting turns of showing download progress
• browser.download.dir sets the directory for downloads
• browser.helperApps.neverAsk.saveToDisk tells Firefox to automatically download the files of the selected mime-types

您可以在浏览器中的 about:config 中查看所有这些首选项.这里还有一个非常详细的文档页面:About:config条目.

You can view all these preferences at about:config in the browser. There is also a very detailed documentation page available here: About:config entries.

此外，我不会使用 xpath 方法，而是使用 find_element_by_partial_link_text():

Besides, instead of using xpath approach, I would use find_element_by_partial_link_text():

driver.find_element_by_partial_link_text("DEV.tgz").click()

另见:

• 访问 Firefox 中的文件下载对话框
• Firefox + Selenium WebDriver 并自动下载 csv 文件
