我正在使用selenium webdriver在python中进行编码以自动化某些操作，但是selenium的{{1}}方法不起作用。
这些是我正在尝试的网页： https://campus.webex.com/mw3300/mywebex/default.do?siteurl=campus&service=10
和
https://webmail.aruba.it/cgi-bin/ajaxmail
和
http://campus.istitutovolta.eu/index.php
我尝试了所有策略：by_class，by_link，by_name，by_id，等等。。。没什么！我使用壁虎和Firefox。这是代码：
find_element_*答案 0 :(得分：1)
更新2 + 3：
我有工作了：请检查一下：
变种1：
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
browser = webdriver.Firefox()
delay = 100 # seconds
# browser.get("https://campus.webex.com/mw3100/mywebex/default.do?siteurl=campus")
browser.get("https://campus.webex.com/mw3300/mywebex/login/login.do?siteurl=campus&login_return_url=%2Ftc3300%2Ftrainingcenter%2Fsite%2FinstantSession.do%3Fsiteurl%3Dcampus")
myelem = WebDriverWait(browser, delay).until(EC.presence_of_element_located((By.ID, 'mwx-ipt-username')))
utente = browser.find_element_by_id("mwx-ipt-username").send_keys('user@gestione.eu')
变种2：
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
browser = webdriver.Firefox()
delay = 20 # seconds
browser.get("https://campus.webex.com/mw3100/mywebex/default.do?siteurl=campus")
browser.switch_to.frame("mainFrame")
browser.switch_to.frame("main")
myelem = WebDriverWait(browser, delay).until(EC.presence_of_element_located((By.ID, 'mwx-ipt-username')))
utente = browser.find_element_by_id("mwx-ipt-username").send_keys('user@gestione.eu')
问题在于站点中的框架。在经过解析的selenium html代码中， 缺少框架的内容，因此是同义词，未找到登录表单。可以通过以下方式对此进行补救：a）变体1：。您直接打开相应的框架。 b）变体2：：从原始页面切换到框架。
请参阅：How to navigate a subframe inside a frameset using Selenium WebDriver with Python?
function for switching frames in python, selenium
How to identify and switch to the frame in selenium webdriver when frame does not have id
How to navigate a subframe inside a frameset using Selenium WebDriver?
更新：我将尝试通过网站提供的按钮找到解决方案。给我一点时间。
我点击了您的链接，并检查了“ userName”，没有“ userName”。
如果您在普通的Firefox中打开一个新标签，然后键入
，则相同其中的“ view-source:https://campus.webex.com/mw3300/mywebex/default.do?siteurl=campus”。
我尝试过：
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
browser = webdriver.Firefox()
delay = 30 # seconds
try:
browser.get("https://campus.webex.com/mw3100/mywebex/default.do?siteurl=campus&service=7")
except:
print("pagina non trovata")
myelem = WebDriverWait(browser, delay).until(EC.presence_of_element_located((By.ID, 'mwx-ipt-username')))
try:
utente = browser.find_element_by_id("mwx-ipt-username")
except:
print("elemento non trovato")
它不起作用。

您可以尝试使用By模块：
from selenium.webdriver.common.by import By
from selenium import webdriver
browser = webdriver.Firefox()
browser.get("https://www.theurl.com")
browser.find_element(By.NAME,"userName").send_keys("Test")
答案 2 :(得分：0)
谢谢你们。登录后，Lukas的解决方案可以正常工作。但是我不明白为什么它仅适用于您使用的链接。实际上，如果我使用此其他链接“ https://campus.webex.com/mw3300/mywebex/default.do?siteurl=campus&service=7”，则需要使用“ cos，因为有更多功能，这是行不通的！相同的代码不起作用！为什么？？？ 我切换到Python 2.7，但是存在一些ASCII问题。...也许是这个原因？
这是我的代码：
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
browser = webdriver.Firefox()
delay = 100 # seconds
browser.get("https://campus.webex.com/mw3300/mywebex/default.do?siteurl=campus&service=7")
myelem = WebDriverWait(browser, delay).until(EC.presence_of_element_located((By.ID, 'mwx-ipt-username')))
utente = browser.find_element_by_id("mwx-ipt-username").send_keys('User')
psw = browser.find_element_by_id("mwx-ipt-password").send_keys('Psw')
myelem.submit()
但是此代码找不到元素...为什么？
再见
