Question

当您单击每部电话下的“查看选项”按钮并将它们放入字符串列表时，我试图提取https://shop.freedommobile.ca/devices拥有的所有网址。

我正在将python与Selenium和wait库一起使用。我已经尝试在参数中使用.text。但是，我一直遇到以下错误：

typeError：“ str”对象不可调用问题是第17行。

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


driver = webdriver.Chrome()

class phoneCost:


    driver.get("https://shop.freedommobile.ca/devices")

    # extract the names of the phones
    wait = WebDriverWait(driver, 20) #10 second wait
    XPathLocation = """B//*[@id="skip-navigation"]/div/div/div[1]/div/div[2]/a'"""
    phonePlanLinksRaw = wait.until(EC.presence_of_all_elements_located(By.XPATH(XPathLocation)))
    phonePlanLinks = []


    for element in range(len(phonePlanLinksRaw)):
        link = element
        phonePlanLinks.append(str(link))


    numLink = 1
    for element in range(len(phonePlanLinks)):
        print("phone " + str(numLink) + " : " + phonePlanLinks[element])
        numLink += 1

应以字符串格式返回网址列表：

[https://shop.freedommobile.ca/devices/Apple/iPhone_XS_Max?sku=190198786135&planSku=Freedom%20Big%20Gig%2015GB

，

https://shop.freedommobile.ca/devices/Apple/iPhone_XS?sku=190198790569&planSku=Freedom%20Big%20Gig%

，

https://shop.freedommobile.ca/devices/Apple/iPhone_XR?sku=190198776631&planSku=Freedom%20Big%20Gig%2015GB]

感谢任何帮助谢谢

Answer 1

这是您应该使用的逻辑。

WebDriverWait(driver,10).until(EC.presence_of_all_elements_located((By.XPATH,"//div[starts-with(@class,'deviceListItem')]/a")))
mblOptions = driver.find_elements_by_xpath("//div[starts-with(@class,'deviceListItem')]/a")
mblUrls = []
for mblOption in mblOptions:
    mblUrls.append(mblOption.get_attribute('href'))

print (mblUrls)

输出：

Answer 2

尝试使用列表推导来获得结果。只需查看您使用过的(By.XPATH(XPathLocation)))这部分wait.until(EC.visibility_of_all_elements_located((By.XPATH, "some_xpath")))即可。

修正的一个更像是：

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

with webdriver.Chrome() as driver:
    wait = WebDriverWait(driver, 10)
    driver.get("https://shop.freedommobile.ca/devices")
    item_links = [item.get_attribute("href") for item in wait.until(EC.visibility_of_all_elements_located((By.XPATH, "//a[contains(@class,'__DeviceDetailsButton')]")))]
    print(item_links)

Answer 3

要使用https://shop.freedommobile.ca/devices提取Selenium具有的所有URL，您必须为visibility_of_all_elements_located()引入 WebDriverWait ，并且可以使用以下Locator Strategy ：

代码块：

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

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
# options.add_argument('disable-infobars')
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
driver.get("https://shop.freedommobile.ca/devices")
print([my_elem.get_attribute("href") for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//a[text()='See Options']")))])

控制台输出：
