Question

我正在尝试获取此页面上帖子的链接，但它们显然是通过单击每个帖子图片生成的。我在 Python 3.8 中使用 Selenium 和 beautifulsoup4。知道如何在 selenium 继续访问下一页时获取链接吗？

网址：https://www.goplaceit.com/cl/mapa?id_modalidad=1&tipo_pro//*[@id=%22gpi-property-list-container%22]/div[3]/div[1]/div[1]/imgpiedad=1%2C2&selectedTool=list#12/-33.45/-70.66667

点击图片后，它会打开一个新标签，其中包含以下类型的缩短网址：https://www.goplaceit.com/propiedad/6198212

将我发送到一个 url 类型：

您可以通过单击图片、保存您的网址、返回第一页并对所有图片重复此操作来轻松获取网址：

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 import webdriver

driver.get("https://www.goplaceit.com/cl/mapa?id_modalidad=1&tipo_propiedad=1%2C2&selectedTool=list#8/-33.958/-71.206")
images = WebDriverWait(driver, 30).until(EC.presence_of_all_elements_located((By.XPATH, "//div[@class='sc-iyvyFf ljSqTz']//img")))
urls = []
for i, image in enumerate(images):
    window_before = driver.window_handles[0]
    image.click()
    driver.implicitly_wait(2)
    window_after = driver.window_handles[i+1]
    driver.switch_to.window(window_after)
    urls.append(driver.current_url)
    driver.switch_to.window(window_before)
