在 Selenium/BeautfulSoup 中的下一页迭代，用于抓取电子商务网站

Question

I'm scraping an E-Commerce website, Lazada using Selenium and bs4, I manage to scrape on the 1st page but I unable to iterate to the next page. What I'm tyring to achieve is to scrape the whole pages based on the categories I've selected.

Here what I've tried :

# Run the argument with incognito

option = webdriver.ChromeOptions()

option.add_argument(' — incognito')

driver = webdriver.Chrome(executable_path='chromedriver', chrome_options=option)

driver.get('https://www.lazada.com.my/')

driver.maximize_window()

# Select category item #


element = driver.find_elements_by_class_name('card-categories-li-content')[0]

webdriver.ActionChains(driver).move_to_element(element).click(element).perform()

t = 10

try:
    
WebDriverWait(driver,t).until(EC.visibility_of_element_located((By.ID,"a2o4k.searchlistcategory.0.i0.460b6883jV3Y0q")))
except TimeoutException:

    print('Page Refresh!')

    driver.refresh()

element = driver.find_elements_by_class_name('card-categories-li-content')[0]

webdriver.ActionChains(driver).move_to_element(element).click(element).perform()

print('Page Load!')

#Soup and select element

def getData(np):

    soup = bs(driver.page_source, "lxml")

    product_containers = soup.findAll("div", class_='c2prKC')

    for p in product_containers:

        title = (p.find(class_='c16H9d').text)#title

        selling_price = (p.find(class_='c13VH6').text)#selling price

        try:

            original_price=(p.find("del", class_='c13VH6').text)#original price 

        except:

            original_price = "-1"

        if p.find("i", class_='ic-dynamic-badge ic-dynamic-badge-freeShipping ic-dynamic-group-2'):
            freeShipping = 1
        else:
            freeShipping = 0
        try:
            discount = (p.find("span", class_='c1hkC1').text)
        except:
            discount ="-1"
        if p.find(("div", {'class':['c16H9d']})):
            url = "https:"+(p.find("a").get("href"))
        else:
            url = "-1"
        nextpage_elements = driver.find_elements_by_class_name('ant-pagination-next')[0]
     
 np=webdriver.ActionChains(driver).move_to_element(nextpage_elements).click(nextpage_elements).perform()
        
        
        print("- -"*30)
        toSave = [title,selling_price,original_price,freeShipping,discount,url]
        print(toSave)
        writerows(toSave,filename)

getData(np)

Answer 1

The problem might be that the driver is trying to click the button before the element is even loaded correctly.

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.Chrome(PATH, chrome_options=option)

# use this code after driver initialization
# this is make the driver wait 5 seconds for the page to load.

driver.implicitly_wait(5)

url = "https://www.lazada.com.ph/catalog/?q=phone&_keyori=ss&from=input&spm=a2o4l.home.search.go.239e359dTYxZXo"
driver.get(url)

next_page_path = "//ul[@class='ant-pagination ']//li[@class=' ant-pagination-next']"

# the following code will wait 5 seconds for
# element to become clickable
# and then try clicking the element. 

try:
    next_page = WebDriverWait(driver, 5).until(
                    EC.element_to_be_clickable((By.XPATH, next_page_path)))
    next_page.click()

except Exception as e:
    print(e)

EDIT 1

Changed the code to make the driver wait for the element to become clickable. You can add this code inside a while loop for iterating multiple times and break the loop if the button is not found and is not clickable.
