Selenium webdriver 找不到收件箱元素

问题描述

因为我还没有找到解决方案，所以从两个月前开始遇到这个问题.我正在使用 Firefox 驱动程序查找并单击名为收件箱"的超链接，但经过详尽尝试后，Selenium 仍然找不到该元素.任何帮助将不胜感激，因为我真的无法找到 Selenium webdriver 找不到该元素的原因.

Bumping this from two months ago since I have not found a solution. I am using Firefox driver to find and then click on a hyperlink named "Inbox" but after exhaustive attempts, Selenium still can't find the element. Any help would be appreciated as I genuinely have not been able to find a reason why Selenium webdriver cannot find the element.

在下面的 HTML 代码中，我考虑过可能有一个框架但找不到；如果有人可以确认以下代码中实际上没有 iframe，将不胜感激！我的脚本中也已经有一个 time.sleep(40) 允许有足够的时间让 webdriver 找到元素.所以我的想法已经不多了，但我想也许收件箱"超链接元素之前的#text元素(    &nbsp")可能会通过隐藏收件箱"而导致问题"元素?任何有关如何进行的提示将不胜感激；下面列出了我所有的解决方法.

In the below HTML code, I have considered that there might be a frame but none can be found; if someone could confirm that there in fact is no iframe in the below code that would be appreciated! I also already have a time.sleep(40) in my script to allow for enough time for webdriver to find the element. So I am running out of ideas, but was thinking that maybe the #text element ("    &nbsp") right before the "inbox" hyperlink element might be causing the issue by hiding the "inbox" element? Any tips on how to proceed would be appreciated; all my attempts at resolution are listed below.

以下是我的代码，直到出现此元素问题(URL 已被删除，因为它是专有的):

Below is my code up until this element issue comes up (URL has been removed as it is proprietary):

from selenium import webdriver
import time

driver = webdriver.Firefox()
driver.get("[URL REMOVED]")
time.sleep(2)
elem1 = driver.find_element_by_css_selector('#main-content > div > div.col-md-4.radix-layouts-sidebar.sidebar-right.panel-panel.sidebar > div > div.panel-pane.pane-entity-field.pane-it-service-field-related-services.block > div > div > ul > li:nth-child(1) > a')
elem1.click()
#Logging in
time.sleep(40)
#Now in the System, click on Inbox Button
elem2 = driver.find_element_by_??? # Trying to figure out this code to find inbox element
elem2.click()

我尝试了以下方法来尝试查找元素:

I have tried the below in trying to find the element :

find_element_by_xpath('//td[@class=’MENUCHOICE’]//a[@href="main.do?action=inbox"]')
find_element_by_xpath('/html/body/table/tbody/tr[6]/td/a')
find_element_by_link_text('Inbox')
find_element_by_partial_link_text('Inb')
find_element_by_css_selector('body > table > tbody > tr:nth-child(6) > td > a')
find_element_by_css_selector("td.MENUCHOICE a[href='main.do?action=inbox']")

我尝试过的所有定位器都会引发 'selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element'

我无法提供该页面的链接，因为它是专有的，但下面我提供了页面 HTML，以防有人可以提供帮助(感兴趣的元素位于倒数第二个 MENUCHOICE 类:收件箱):

I cannot provide the link to the page as it's proprietary, but below I have provided the page HTML in case someone can assist (The element of interest is under the second to last MENUCHOICE class: Inbox):

感谢您的帮助.

解决方案

这个问题已经在一个月前解决了.事实证明，对于这个特定的 Web 应用程序，Selenium webdriver 需要从一开始就具有直接链接；否则它不会识别"它所在的页面.此网络应用程序通常不直接链接；您通常会通过发布链接的中间页面.

This issue was resolved a month ago. It turns out that for this particular web application, Selenium webdriver needed to have a direct link from the get-go; otherwise it would not "recognize" the page it was on. This web app is usually not linked to directly; you usually go through an intermediary page that has the link posted.

我通过将 Selenium 直接定向到 Web 应用程序来解决此问题，而不是先通过中间页面并单击 Web 应用程序链接.即:

I resolved this by directing Selenium to the web application directly instead of going through the intermediary page first and clicking on the web app link. I.e.:

    from selenium import webdriver
    import time

    driver = webdriver.Firefox()
    driver.get("[DIRECT LINK INSTEAD OF INTERMEDIARY PAGE LINK]")

希望这对以后遇到类似问题的人有所帮助.

Hope this helps anyone with a similar issue in the future.
