如何使用GOOGLE的等待加载g-Load图标也在用PYTHON问硒？ [英] How to use Wait for loading g-loading-icon of Google People Also Ask in Selenium with python?

问题描述

第一个。我非常感谢@Cruisepandey在这个话题上对我的帮助： How to crawl question and answer of Google People Also Ask with Selenium and Python?

所以我被这样使用他的代码：

    driver = webdriver.Chrome(driver_path)
    driver.maximize_window()
    driver.implicitly_wait(30)
    wait = WebDriverWait(driver, 30)
    
    driver.get("https://www.google.com/search?q=How%20to%20make%20bakery%3F&source=hp&ei=j0aZYYjRAvja2roPrcWcyAU&iflsig=ALs-wAMAAAAAYZlUn4NMUPjfIpQmrXSmjIDnaWjJXWIJ&ved=0ahUKEwjI1JDn0Kf0AhV4rVYBHa0iB1kQ4dUDCAc&uact=5&oq=How%20to%20make%20bakery%3F&gs_lcp=Cgdnd3Mtd2l6EAMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBNQAFgAYJMDaABwAHgAgAF-iAF-kgEDMC4xmAEAoAECoAEB&sclient=gws-wiz")
    
    all_questions = driver.find_elements(By.XPATH, "//span[text()='People also ask']/../following-sibling::div/descendant::div[@data-hveid and @class and @jsname and @data-ved]")
    print(len(all_questions))
    
    j = 1
    for question in all_questions:
        time.sleep(1)
        ele = driver.find_element(By.XPATH, f"(//span[text()='People also ask']/../following-sibling::div/descendant::div[@data-hveid and @class and @jsname and @data-ved])[{j}]")
        j = j + 2
        ele.click()
        time.sleep(1)
        answer = ele.find_element(By.XPATH, ".//../following-sibling::div").get_attribute('innerText')
        print(answer)
        print('--------------')

这段代码非常有用。但我想问两个问题。

1. 单击以显示答案时。如果没有使用时间。睡眠(1)，我会使用等待答案显示，如何得到确切的类和代码来等待答案显示？
2. 如果上网速度慢，代码会有问题。当单击更多时，将不会显示结果。我尝试使用等待，直到不可见性_元素_定位到加载图标。但我对XPath的理解不正确。有什么办法做到这一点吗？ 这是我的代码更新@Cruisepandey：

    driver = webdriver.Chrome(driver_path)
    driver.maximize_window()
    driver.implicitly_wait(30)
    wait = WebDriverWait(driver, 30)
    
    driver.get("https://www.google.com/search?q=How%20to%20make%20bakery%3F&source=hp&ei=j0aZYYjRAvja2roPrcWcyAU&iflsig=ALs-wAMAAAAAYZlUn4NMUPjfIpQmrXSmjIDnaWjJXWIJ&ved=0ahUKEwjI1JDn0Kf0AhV4rVYBHa0iB1kQ4dUDCAc&uact=5&oq=How%20to%20make%20bakery%3F&gs_lcp=Cgdnd3Mtd2l6EAMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBNQAFgAYJMDaABwAHgAgAF-iAF-kgEDMC4xmAEAoAECoAEB&sclient=gws-wiz")
    
    all_questions = driver.find_elements(By.XPATH, "//span[text()='People also ask']/../following-sibling::div/descendant::div[@data-hveid and @class and @jsname and @data-ved]")
    print(len(all_questions))
    
    j = 1
    for question in all_questions:
        time.sleep(1)
        ele = driver.find_element(By.XPATH, f"(//span[text()='People also ask']/../following-sibling::div/descendant::div[@data-hveid and @class and @jsname and @data-ved])[{j}]")
        j = j + 2
        ele.click()
    
        # Question 1: To waiting answer show.
        timeout  = 30
        answer_css_class = 'wWOJcd'
        try:
    
            is_question_show = WebDriverWait(driver, timeout).until(
                EC.presence_of_element_located((By.CLASS_NAME, answer_css_class))
            )
        except TimeoutException:
            pass
    
        time.sleep(1)
        answer = ele.find_element(By.XPATH, ".//../following-sibling::div").get_attribute('innerText')
    
        # Question 2: To waiting G loading icon when click more answer with slow internet.
        loading_element_xpath = '/html/body/div[7]/div/div[9]/div[1]/div/div[2]/div[2]/div/div/div[2]/div/div/div[1]/g-loading-icon'
        try:
    
            is_question_show = WebDriverWait(driver, timeout).until(
                EC.presence_of_element_located((By.XPATH, loading_element_xpath))
            )
        except TimeoutException:
            pass
    
        print(answer)
        print('--------------')

所以有什么办法不用时间吗？睡觉，然后在Selify中使用等待？

推荐答案

我认为您不需要invisibility_of_element_located来加载图标。

您可以单独尝试--问题和答案除外。

编码：

driver = webdriver.Chrome(driver_path)
driver.maximize_window()
wait = WebDriverWait(driver, 30)


driver.get("https://www.google.com/search?q=How%20to%20make%20bakery%3F&source=hp&ei=j0aZYYjRAvja2roPrcWcyAU&iflsig=ALs-wAMAAAAAYZlUn4NMUPjfIpQmrXSmjIDnaWjJXWIJ&ved=0ahUKEwjI1JDn0Kf0AhV4rVYBHa0iB1kQ4dUDCAc&uact=5&oq=How%20to%20make%20bakery%3F&gs_lcp=Cgdnd3Mtd2l6EAMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBMyBAgAEBNQAFgAYJMDaABwAHgAgAF-iAF-kgEDMC4xmAEAoAECoAEB&sclient=gws-wiz")

all_questions = driver.find_elements(By.XPATH, "//span[text()='People also ask']/../following-sibling::div/descendant::div[@data-hveid and @class and @jsname and @data-ved]")
print(len(all_questions))

j = 1
for question in all_questions:
    try:
        ele = wait.until(EC.visibility_of_element_located((By.XPATH, f"(//span[text()='People also ask']/../following-sibling::div/descendant::div[@data-hveid and @class and @jsname and @data-ved])[{j}]")))
        ele.click()
        j = j + 2
    except:
        print("Could not click on Question link")
    try:
        answer = ele.find_element(By.XPATH, ".//../following-sibling::div").get_attribute('innerText')
        print(answer)
    except:
        print("Could not read answer.")

导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
