如果项目是“库存”，我如何告诉selenium添加到篮子中？

Question

如果项目是库存的，我有以下代码打印“库存”：

from selenium import webdriver

from selenium.webdriver.chrome.options import Options

from selenium.webdriver.support.ui import WebDriverWait

from selenium.webdriver.common.by import By

from selenium.webdriver.support import expected_conditions as EC


options=Options()
driver=webdriver.Chrome(options=options)
    
#Directing to site
driver.get("https://www.amazon.co.uk/Nintendo-Switch-OLED-Model-Neon/dp/B098TNW7NM/ref=sr_1_3?keywords=Nintendo+Switch&qid=1651147043&sr=8-3");
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "/html/body/div[2]/span/form/div[3]/span[1]/span/input"))).click()



condition= print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//div[@id='availability']//span[contains(text(),'In stock.')]"))).get_attribute("innerHTML"))
if condition == 'In stock.':
    
    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "/html/body/div[2]/div[3]/div[6]/div[4]/div[1]/div[2]/div/div/div/div/div/div/form/div/div/div/div/div[3]/div/div[14]/div[1]/span/span/span/input"))).click()

else:
    pass

我如何告诉selenium‘添加到篮子’，如果项目是‘在库存’？

我想：

转到这个url：https://www.amazon.co.uk/Nintendo-Switch-OLED-Model-Neon/dp/B098TNW7NM/ref=sr_1_3?keywords=Nintendo+Switch&qid=1651147043&sr=8-3的

1. 检查右侧的文本是否显示“库存”..

1. 如果有存货，我想把它加到篮子里。

我通过检查->copy->copy路径获得xpath。

Answer 1

理想情况下，您应该使用相对XPath。

我们使用的是presence_of_all_elements_located，如果没有找到，它将返回一个list of web elements，如果没有，它将是an empty list，因此in_stock是一个web元素列表。现在，len()是一种方法，它将为我们提供列表中有多少web元素的输出。因此，逻辑是这样的，如果列表有任何内容，那么它必须是In stock -> Now add to basket，否则它必须是<0或0 --在这种情况下，"In stock"不会出现，我们也不会在篮子中添加任何东西。

下面的代码转到URL，查找"In stock" text，如果它存在，那么"Add to basket" (如果不是简单的tear down bot )。

代码：

driver.maximize_window()
wait = WebDriverWait(driver, 30)

driver.get("https://www.amazon.co.uk/Nintendo-Switch-OLED-Model-Neon/dp/B098TNW7NM/ref=sr_1_3?keywords=Nintendo+Switch&qid=1651147043&sr=8-3")
try:
    wait.until(EC.element_to_be_clickable((By.XPATH, "/html/body/div[2]/span/form/div[3]/span[1]/span/input"))).click()
    print("clicked on accept cookies successfully")
except:
    pass

in_stock = wait.until(EC.presence_of_all_elements_located((By.XPATH, "//div[@id='availability']//span[contains(text(),' In stock. ')]")))
try:
    if len(in_stock) > 0:
        print("In stock must be present.")
        wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#add-to-cart-button"))).click()
        print("Clicked on add to cart button")
    else:
        print("In stock must be not present")
except:
    print("Something went wrong")
    pass

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

假设代码的最后一行返回“库存”

condition=WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//div[@id='availability']//span[contains(text(),'In stock.')]"))).get_attribute("innerHTML")

if condition == 'in stock':
    # logic to add to cart
else:
    pass
