我一直试图让这段代码工作，但它不会。（该链接是一个占位符，我计划将其更改为 3060 Ti 以获得一个用于家庭装备。）它还说 goToCartBtn 被点击，但它没有。

import time
from selenium import webdriver
#For using chrome
browser = webdriver.Chrome('/Users/admin/Downloads/chromedriver')

#BestBuy RTX 3060 Ti webpage
browser.get('https://www.bestbuy.com/site/nvidia-geforce-rtx-nvlink-bridge-for-3090-cards-space-gray/6441554.p?skuId=6441554')


buyButton = False 

while not buyButton:
try:
    #If this works, then the button is not pytopen
    addToCartBtn = addButton = browser.find_element_by_class_name("btn-disabled")

    #Button isn't open, restart the script
    print("Button isn't ready yet.")

    #Refresh page after a delay
    time.sleep(1)
    browser.refresh()

except:

    addToCartBtn = addButton = browser.find_element_by_class_name("btn-primary")

    #Click the button 
    print("Button was clicked.")
    addToCartBtn.click()
    
    goToCartBtn = addButton = browser.find_element_by_class_name("btn-secondary")

    print("Go To Cart button was clicked.")
    goToCartBtn.click()

    checkoutBtn = addButton = browser.find_element_by_class_name("btn-lg")

    print("Checkout button clicked.")
    checkoutBtn.click()
    buyButton = True

错误信息如下所示：

您不需要“转到购物车”按钮，只需要一个 URL“bestbuy.com/cart”，我将它用于我的机器人。

您的 goToCartButton 选择器不够具体。

 goToCartButton = browser.find_element_by_class_name('btn-secondary')

使用这个选择器返回五个元素，Selenium 只会与它找到的第一个元素交互，根据 DOM，它不是“转到购物车”按钮。

相反，您可以使用 CSS 选择器来返回特定元素。使用 CSS：

goToCartButton = browser.find_element_by_css_selector('.go-to-cart-button .btn-secondary')

你现在应该可以点击按钮了。
