Python selenium 获取页面标题

Question

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
from selenium.webdriver.firefox.options import Options

options = Options()
options.headless = True
driver = webdriver.Firefox(options=options)
driver.get("https://hapondo.qa/rent/doha/apartments/studio")
element = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.XPATH, "/html/head/title"))
)

print(element.text)

在无头选项下无法获取页面标题？试图等待，甚至尝试driver.title

Answer 1

您需要注意以下几点：

• 要检索页面标题而不是使用xpath，您需要使用driver.title
• hapondo 网站包含JavaScript 启用的元素。

解决方案

要提取页面标题，您需要将WebDriverWait 诱导为title_contains()，您可以使用以下任一Locator Strategy：

• 代码块：

  from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  
  options = webdriver.ChromeOptions() 
  options.add_argument('--headless')
  options.add_argument('--window-size=1920,1080')
  driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
  driver.get('https://hapondo.qa/rent/doha/apartments/studio')
  WebDriverWait(driver, 10).until(EC.title_contains("hapondo"))
  print(driver.title)
  

• 控制台输出：

  Studio Apartments for rent in Doha | hapondo

Answer 2

“页面标题”是指浏览器顶部选项卡上显示的文本。

对您的代码改动很小的解决方案：

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


driver = webdriver.Firefox(executable_path=r"[path]")
driver.get("https://hapondo.qa/rent/doha/apartments/studio")


element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.XPATH, "/html/head/title"))
    )

print(element.get_attribute("innerHTML"))
Output: Studio Apartments for rent in Doha | hapondo

获取该文本的另一种方法是简单地使用driver.title。

“title 方法用于检索用户当前正在处理的网页的标题。”

from selenium import webdriver
import time
driver = webdriver.Firefox(executable_path=r"[PATH]")
driver.get("https://hapondo.qa/rent/doha/apartments/studio")
time.sleep(2)

print(driver.title)
#Output: Studio Apartments for rent in Doha | hapondo
