如何使用PYTHON使Selenium获得href？
提问于 2022-08-15 21:31:01
我尝试了我在这里找到的所有方法，https://selenium-python.readthedocs.io/locating-elements.html，但我无法从页面中获得该链接。
我需要从href获得链接。
HTML页面代码：
<p style="margin: 0px 30px 30px 30px;text-align: center;-webkit-box-sizing: border-box;max-width: 100%;-moz-box-sizing: border-box;box-sizing: border-box;">

<center style="color:#ffffff;font-family:sans-serif;font-size:13px;font-weight:bold;">CLICK TO VERIFY EMAIL</center>
</v:roundrect>

CLICK TO VERIFY EMAIL
</a>
一些失败的尝试：
link_ativador = navegador.find_element(By.LINK_TEXT, 'CLICK TO VERIFY EMAIL')
print(link_ativador)
link_ativador = navegador.find_element(By.XPATH, '/html/body/table/tbody/tr[2]/td/table/tbody/tr[3]/td/table/tbody/tr/td/p[3]/a').get_attribute('href')
print(link_ativador)
link_ativador = navegador.find_element(By.LINK_TEXT, 'CLICK TO VERIFY EMAIL').get_attribute('href')
print(link_ativador)+一些失败的尝试：
link_try1 = WebDriverWait(navegador, 20).until(EC.presence_of_element_located((By.XPATH, '//a[text()="CLICK TO VERIFY EMAIL"]'))).get_attribute('href')
print(link_try1)
link_try2 = (WebDriverWait(navegador, 20).until(EC.visibility_of_element_located((By.PARTIAL_LINK_TEXT, "CLICK TO VERIFY EMAIL"))).get_attribute("href"))
print(link_try2)
link_try3 = (WebDriverWait(navegador, 20).until(EC.visibility_of_element_located((By.XPATH, "//a[contains(., 'CLICK TO VERIFY EMAIL')]"))).get_attribute("value"))
print(link_try3)完整的代码：

您应该能够使用以下定位器获得该href：
link_url = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.XPATH, '//a[text()="CLICK TO VERIFY EMAIL"]'))).get_attribute('href')您还需要导入：
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC硒文档：https://www.selenium.dev/documentation/
编辑:在OP确认实际的url后，我们可以看到该链接位于iframe中，因此下面的代码将检索它：
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import Select
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
chrome_options = Options()
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument('disable-notifications')
chrome_options.add_argument("window-size=1280,720")
webdriver_service = Service("chromedriver/chromedriver") ## path to where you saved chromedriver binary
browser = webdriver.Chrome(service=webdriver_service, options=chrome_options)
actions = ActionChains(browser)
url = 'https://tmail.link/inbox/ambers.rushing@tmail.link/b2b20ce5eeb40a74a8c4ce7d4438883fa44a69c1/'
browser.get(url)
WebDriverWait(browser, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH, "//iframe[@src='1']")))
specific_url = WebDriverWait(browser, 20).until(EC.visibility_of_element_located((By.PARTIAL_LINK_TEXT, "CLICK TO VERIFY EMAIL"))).get_attribute("href")
print(specific_url)这将在终端打印：

该元素是一个动态元素，因此提取href的值以导出的WebDriverWait，您可以使用以下任何一个
使用
- 的PARTIAL_LINK_TEXT：
打印(驱动程序，20).until(EC.visibility_of_element_located((By.PARTIAL_LINK_TEXT，“单击以验证EMAIL"))).get_attribute("href")) )
使用XPATH的
- ：
打印(驱动程序，20).until(EC.visibility_of_element_located((By.XPATH，"//acontains(. )，‘单击以验证EMAIL')"))).get_attribute("value"))
- Note：您必须添加以下导入：
从selenium.webdriver.support.ui导入WebDriverWait从selenium.webdriver.common.by导入从selenium.webdriver.support导入expected_conditions作为EC
