如何使用 Selenium 和 Python 提取產品名稱

Question

我正在嘗試從技術站點獲取數據，但是當我嘗試打印 productBox 變量 output 時顯示：[] 有人可以解決嗎

from selenium import webdriver
driver = webdriver.Chrome()
driver.get('https://www.itopya.com/bilgisayar/masaustu/oyun-bilgisayarlari/')
data = driver.find_element_by_id('allProducts')
productBox = data.find_elements_by_class_name('product col-md-3')
print(productBox)

Answer 1

要打印產品名稱，您必須為visibility_of_all_elements_located()引入WebDriverWait ，並且您可以使用以下任一Locator Strategies ：

• 使用CSS_SELECTOR ：

   driver.get("https://www.itopya.com/bilgisayar/masaustu/oyun-bilgisayarlari/?__cf_chl_jschl_tk__=f128b939cc717f7b22114e1e0f850e5b3cf16d59-1594571020-0-Aaj8nKhAOskxwytnAGUERyGvp77H0pQGK05Lmlkoq0ec5KDpM_1dDn_QLd7n-RueS6-HeAUXEbxqUIGNrGxcavD3O5G58hK-0BiQRnZVV6kr4lOBK7zHG7hMbUmjfjmYL_U_T7MKMi8rzaKgpnW5q9u4x-75lLaO8hf075M_x7788TNXBhsWuFFCxCOmBEqBrxV4J7klhj9tGaU1vYtpqY_ZDKtWuV8EkHYwswACUqLO53ddGwIjI2x1Uu22KxFy9XdvcE47dBPBp1pzcpwyZHnap625G7vxmIoZBMlq1JEgCIWUu-FMqpPlGhTpxigJwCkHaIvqcW9RlkvTbKo9PsruvjCIQFqEjD2JQSwX3LQzVVwmipkD2GNOjsLsQ6ypRKYwWSZ07AOzLuKny9mqvOQ") print([my_elem.get_attribute("innerHTML") for my_elem in WebDriverWait(driver, 5).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div.product-inner div.product-title>a")))])

• 使用XPATH ：

   driver.get("https://www.itopya.com/bilgisayar/masaustu/oyun-bilgisayarlari/?__cf_chl_jschl_tk__=f128b939cc717f7b22114e1e0f850e5b3cf16d59-1594571020-0-Aaj8nKhAOskxwytnAGUERyGvp77H0pQGK05Lmlkoq0ec5KDpM_1dDn_QLd7n-RueS6-HeAUXEbxqUIGNrGxcavD3O5G58hK-0BiQRnZVV6kr4lOBK7zHG7hMbUmjfjmYL_U_T7MKMi8rzaKgpnW5q9u4x-75lLaO8hf075M_x7788TNXBhsWuFFCxCOmBEqBrxV4J7klhj9tGaU1vYtpqY_ZDKtWuV8EkHYwswACUqLO53ddGwIjI2x1Uu22KxFy9XdvcE47dBPBp1pzcpwyZHnap625G7vxmIoZBMlq1JEgCIWUu-FMqpPlGhTpxigJwCkHaIvqcW9RlkvTbKo9PsruvjCIQFqEjD2JQSwX3LQzVVwmipkD2GNOjsLsQ6ypRKYwWSZ07AOzLuKny9mqvOQ") print([my_elem.get_attribute("innerHTML") for my_elem in WebDriverWait(driver, 5).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='product-inner']//div[contains(@class, 'product-title')]/a")))])

• 控制台 Output：
