Python 为 Selenium 设置 Firefox 首选项--下载位置

Question

我使用 Selenium Marrionette 和 GeckoDriver 来提取网络数据。我使用以下设置我的 Firefox 配置文件首选项：

fp = webdriver.FirefoxProfile()
fp.set_preference("browser.download.folderList", 1)
fp.set_preference("browser.helperApps.alwaysAsk.force", False)
fp.set_preference("browser.download.manager.showWhenStarting",False)
fp.set_preference("browser.download.dir", "H:\Downloads")
fp.set_preference("browser.download.downloadDir","H:\Downloads")
fp.set_preference("browser.download.defaultFolder","H:\Downloads")

binary = FirefoxBinary(r'C:\Program Files (x86)\Mozilla Firefox\Firefox.exe')

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True

driver = webdriver.Firefox(capabilities=firefox_capabilities, firefox_binary=binary, firefox_profile = fp)

据我阅读Unable to set firefox profile preferences and FirefoxProfile passed to FirefoxDriver的理解，现在使用firefox_profile似乎没有做任何事情。因此，我需要对 firefox_capabilities 实施新的更新，但我不确定具体该怎么做。有什么想法吗？

Answer 1

好的，我相信我终于解决了这个问题。我没有使用上面的代码，而是使用了以下指向我的 Firefox 配置文件文件夹的代码（如果您需要更新默认配置文件设置，请在运行此代码之前在 Firefox 中执行此操作）：

from selenium.webdriver.firefox.options import Options
binary = FirefoxBinary(r'C:\Program Files (x86)\Mozilla Firefox\Firefox.exe')
fp = (r'C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles\oqmqnsih.default')
opts = Options()
opts.profile = fp
firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
driver = webdriver.Firefox(capabilities=firefox_capabilities,firefox_binary=binary, firefox_options = opts)

我运行这个代码连同我的 web-scraping 代码，一旦我点击 "Export CSV" link，它就会自动下载，而不是下载管理器 window 弹出。随时添加任何反馈。

我的 python 脚本的解决方案（在 raspi 3 上）：

binary = FirefoxBinary('/usr/bin/firefox')
driver = webdriver.Firefox(capabilities={'browserName': 'firefox' }, firefox_binary=binary)

Answer 3

初始代码部分正确。您必须将 browser.download.folderList 值设置为 2 :

fp = webdriver.FirefoxProfile()
fp.set_preference("browser.download.folderList", 2) # 0 means to download to the desktop, 1 means to download to the default "Downloads" directory, 2 means to use the directory 
fp.set_preference("browser.helperApps.alwaysAsk.force", False)
fp.set_preference("browser.download.manager.showWhenStarting",False)
fp.set_preference("browser.download.dir", "H:\Downloads") 

binary = FirefoxBinary(r'C:\Program Files (x86)\Mozilla Firefox\Firefox.exe')

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True

driver = webdriver.Firefox(capabilities=firefox_capabilities,firefox_binary=binary, firefox_profile = fp)
