使用 Selenium Python ChromeDriver 从弹出窗口/表单下载 PDF

问题描述

无法确定下一步，尝试从网站下载 pdf 文件并卡住.

"

寻找在这种情况下下载 pdf 文件的最有效方法.谢谢！

请试试这个:

chromeOptions = webdriver.ChromeOptions()prefs = {"plugins.always_open_pdf_externally": True}chromeOptions.add_experimental_option("prefs",prefs)驱动程序 = webdriver.Chrome(chrome_options=chromeOptions)driver.get('https://www.southtechhosting.com/SanJoseCity/CampaignDocsWebRetrieval/Search/SearchByElection.aspx')#打开弹窗的代码driver.find_element_by_xpath('//*[@id="ctl00_DefaultContent_ASPxRoundPanel1_btnFindFilers_CD"]').click()driver.find_element_by_xpath('//*[@id="ctl00_GridContent_gridFilers_DXCBtn0"]').click()driver.find_element_by_xpath('//*[@id="ctl00_DefaultContent_gridFilingForms_DXCBtn0"]').click()driver.switch_to.frame(driver.find_element_by_tag_name('iframe'))a = driver.find_element_by_link_text("点击这里")ActionChains(driver).key_down(Keys.CONTROL).click(a).key_up(Keys.CONTROL).perform()

更新:要退出弹出窗口，您可以尝试以下操作:

driver.switch_to.default_content()driver.find_element_by_xpath('//*[@id="ctl00_GenericPopupSizeable_InnerPopupControl_HCB-1"]/img').click()

Having trouble figuring out the next step, trying to download a pdf file from a website and getting stuck.

"https://www.southtechhosting.com/SanJoseCity/CampaignDocsWebRetrieval/Search/SearchByElection.aspx"

Page with Links to PDF Files

PDF file to download

I was able to click on the pdf link from the "Page with Links" using Selenium & ChromeDriver but then I get a popup form instead of a download.

I tried disabling the Chrome PDF Viewer ("plugins.plugins_list":[{"enabled":False,"name":"Chrome PDF Viewer"}]), but that doesn't work.

The popup form (viewed in "PDF file to download") has a hover link to download the pdf file. I've tried ActionChains(), but I get this exception after running this line:

from selenium.webdriver.common.action_chains import ActionChains

element_to_hover = driver.find_element_by_xpath("//paper-icon-button[@id='download']")
hover = ActionChains(driver).move_to_element(element_to_hover)
hover.perform()

Looking for the most efficient way to download pdf files in this type of situation. Thanks!

Please try this:

chromeOptions = webdriver.ChromeOptions()
prefs = {"plugins.always_open_pdf_externally": True}
chromeOptions.add_experimental_option("prefs",prefs)
driver = webdriver.Chrome(chrome_options=chromeOptions)
driver.get('https://www.southtechhosting.com/SanJoseCity/CampaignDocsWebRetrieval/Search/SearchByElection.aspx')

#Code to open the pop-up
driver.find_element_by_xpath('//*[@id="ctl00_DefaultContent_ASPxRoundPanel1_btnFindFilers_CD"]').click()
driver.find_element_by_xpath('//*[@id="ctl00_GridContent_gridFilers_DXCBtn0"]').click()
driver.find_element_by_xpath('//*[@id="ctl00_DefaultContent_gridFilingForms_DXCBtn0"]').click()

driver.switch_to.frame(driver.find_element_by_tag_name('iframe'))
a = driver.find_element_by_link_text("Click here")
ActionChains(driver).key_down(Keys.CONTROL).click(a).key_up(Keys.CONTROL).perform()

UPDATE: To exit the popup, you can try this:

driver.switch_to.default_content()
driver.find_element_by_xpath('//*[@id="ctl00_GenericPopupSizeable_InnerPopupControl_HCB-1"]/img').click()
