Cannot download PDF file in to the specified directory using selenium with python in Firefox browser, pdf file opens in browser window itself

Question

While trying to download a PDF file into a specific directory using Selenium with Python in Firefox browser, the pdf file is not getting downloaded into that directory, it opens in the firefox browser itself. 需要帮助。

不能使用 Firefox_Profile，它已被弃用。

from selenium import webdriver
from selenium.webdriver.firefox.service import Service as FirefoxService
from webdriver_manager.firefox import GeckoDriverManager
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.common.by import By

options = Options()
options.set_preference("browser.download.folderList", 2)
options.set_preference("browser.download.manager.showWhenStarting", False)
options.set_preference("browser.download.dir", 'C:/Temp/PdfDownload')
options.set_preference("browser.download.useDownloadDir", True)
options.set_preference("browser.helperApps.neverAsk.saveToDisk", 'application/pdf')
options.set_preference("pdfjs.disable", True)

driver = webdriver.Firefox(service=FirefoxService(GeckoDriverManager().install()), options = options)
driver.maximize_window()
driver.get("https://file-examples.com/index.php/sample-documents-download/sample-pdf-download/")

driver.find_element(By.XPATH,".//*[text()='Download sample pdf file']").click()

Answer 1

修复这些行：

options.set_preference("browser.download.dir", 'C:\\Temp\\PdfDownload')

和

options.set_preference("pdfjs.disabled", True)
