python - Python Selenium：无法从 Instagram 中获取 HREF 链接标签

Question

PostLinkExtraction = driver.find_element_by_xpath("//article[1]/div[3]/div[1]/div/div[2]/div[1][*[local-name()='a']]").get_attribute('href')
print (PostLinkExtraction)

我试图在我的 Instagram 时间轴上的第一个帖子下打印来自 Instagram 时间戳的 href 链接。上面的代码由于某种原因没有返回。下面是任何想要运行它并查看我可能出错的地方的代码，但我想要完成的总体目标是从 <-time> 标记中提取 href 链接。下图显示了 <-time> 标签在开发者工具中的位置

from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from time import sleep
from selenium.webdriver.common.keys import Keys
from selenium import webdriver

user = 'username'
passw = 'password'



driver = webdriver.Chrome(ChromeDriverManager().install())
driver.get('https://www.instagram.com/')
driver.implicitly_wait(10)

driver.find_element_by_name('username').send_keys(user)
driver.find_element_by_name('password').send_keys(passw)
Login = "//button[@type='submit']"
sleep(2)
driver.find_element_by_xpath(Login).submit()
sleep(1)
# Logs into Instagram
print ('Logged In')

#------------------------ATTENTION

NotNow = "//button[contains(text(),'Not Now')]"
driver.find_element_by_xpath(NotNow).click()
# Clicks Pop Up
print ('Close Pop Up')

# It's weird but the pop up opens once, only after this page.
# If ever a problem delete one, or have the first click be
# directed to your Instagram Profiles timeline

NotNow = "//button[contains(text(),'Not Now')]"
driver.find_element_by_xpath(NotNow).click()
#Clicks Pop Up; Comment out the line above if it causes an error
print ('Close Pop Up')

#-----------------------------------



driver.refresh()
print ('refreshing')
driver.implicitly_wait(10)
PostLinkExtraction = driver.find_element_by_xpath("//article[1]/div[3]/div[1]/div/div[2]/div[1][*[local-name()='a']]").get_attribute('href')
print (PostLinkExtraction)

我发现问题是因为你的 xpath。修复它，您将打印出您的第一篇文章的 href。

PostLinkExtraction = driver.find_element_by_xpath("//article[1]/div[3]/div[1]/div/div[2]/div[1]/a").get_attribute('href')
print (PostLinkExtraction)

结果：
