下载文件Selenium和Firefox

Posted 2021-05-02

我只是编写了以下代码，用于将文档下载到特定文件夹，但是它一直在默认文件夹下载下载，有什么问题？感谢提前帮助

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.options import Options
from selenium.webdriver import ActionChains
from selenium.webdriver.common.action_chains import ActionChains
import time
import os

options = Options();
options.set_preference("browser.download.dir","/Desktop/test-download");
options.set_preference("browser.download.folderList",2);
options.set_preference("browser.download.manager.showWhenStarting", False);
options.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/vnd.ms- 
powerpoint");
driver = webdriver.Firefox(firefox_options=options);

driver.get("https://legacy.python.org/doc/essays/ppt/lwnyc2002/intro22.ppt") 
driver.find_element_by_xpath("**xpath of document**").click()

答案

您将不得不使用FirefoxProfile进行此操作（缩进可能会被破坏）：

fprofile = webdriver.FirefoxProfile()
fprofile.set_preference("browser.download.dir", "/Desktop/test-download")
fprofile.set_preference("browser.download.folderList", 2)
fprofile.set_preference("browser.download.manager.showWhenStarting", False)
fprofile.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/vnd.ms- 
powerpoint")
driver = webdriver.Firefox(firefox_profile=profile)
