为什么使用Python的Selenium webdriver无法访问网站

Question

我正在尝试使用与chrome驱动程序selenium连接到一个网站。但联系不上。下面是我的代码：

    from selenium import webdriver
    from selenium.webdriver.common.by import By
    
    CHROME_EXECUTABLE_PATH = "C://Program Files (x86)//Chrome Driver//chromedriver.exe"
    CHROME_OPTIONS = webdriver.ChromeOptions()
    CHROME_OPTIONS.add_argument("--disable-notifications")
    BASE_URL = "https://www.nordstrom.com/"
    driver = webdriver.Chrome(executable_path=CHROME_EXECUTABLE_PATH, options=CHROME_OPTIONS)
    # locators
    search_button_locator = "//a[@id='controls-keyword-search-popover']"
    search_box_locator = "//*[@id='keyword-search-input']"
    
    driver.get(BASE_URL)
    driver.find_element(By.XPATH, search_button_locator)
    driver.find_element(By.XPATH, search_box_locator).send_keys("Fave Slipper")

这段代码给了我一些错误：

E:\Python\Nordstrom.com\venv\Scripts\python.exe E:/Python/Nordstrom.com/pages/simple.py
Traceback (most recent call last):
  File "E:\Python\Nordstrom.com\pages\simple.py", line 14, in <module>
    driver.find_element(By.XPATH, search_button_locator)
  File "E:\Python\Nordstrom.com\venv\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 976, in find_element
    return self.execute(Command.FIND_ELEMENT, {
  File "E:\Python\Nordstrom.com\venv\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "E:\Python\Nordstrom.com\venv\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//a[@id='controls-keyword-search-popover']"}
  (Session info: chrome=94.0.4606.61)

页面如下所示：

但预期的页面应该如下所示：

如何访问本网站？

Answer 1

错误指出它无法找到XPATH元素，这就是它出错的原因。

造成这种情况的主要原因可能是：

• XPATH错误
• 该元素尚未加载到页面上
• 站点检测到您的刮擦尝试并阻止您
