如何修复webdriver＆＃x27;对象没有CSS选择器查找元素？

Question

我在沙盒上使用callow。我遇到这些错误：

Traceback (most recent call last):
  File "C:\Users\Joe\callow\callow.py", line 163, in <module>
    wizard()
  File "C:\Users\Joe\callow\callow.py", line 93, in wizard
    brutes(username, username_selector, password_selector, submit_selector, pass_list, website)
  File "C:\Users\Joe\callow\callow.py", line 119, in brutes
    Sel_user = browser.find_element_by_css_selector(username_selector) # Finds Selector
AttributeError: 'WebDriver' object has no attribute 'find_element_by_css_selector'

错误起源于：

try:
        Sel_user = browser.find.element_by_css_selector(username_selector) # Finds Selector
    except selenium.common.exceptions.NoSuchElementException:
        print((color.RED + '\n[!]'+ color.CWHITE + ' Username feild selector is invalid.'))
        sys.stdout.flush()
        exit()
    try:
        Sel_pas = browser.find_element_by_css_selector(password_selector) # Finds Selector
    except selenium.common.exceptions.NoSuchElementException:
        print((color.RED + '\n[!]'+ color.CWHITE + ' Password feild selector is invalid.'))
        sys.stdout.flush()
        exit()
    try:
        enter = browser.find.element_by_css_selector(submit_selector) # Finds Selector
    except selenium.common.exceptions.NoSuchElementException:
        print((color.RED + '\n[!]'+ color.CWHITE + ' Login button selector is invalid.'))
        sys.stdout.flush()
        exit()

如何解决此问题？

Answer 1

既然它提到了Webdriver，我假设这与硒有关？ find_element_by_css_selector已弃用，如果您要使用像Pycharm这样的IDE，它将告诉您：

find_element_by_css_selector被弃用。请使用
find_element（by.css_selector，value = css_selector）而不是

，而不是使用find_element_by_css_selector，请使用以下内容：

Sel_user = browser.findElement(By.CSS_SELECTOR, username_selector)

请参阅官方文档以获取更多信息： https://selenium-python.readthedocs.io/locating-elements.html#locating-elements-elements-elements-by-css-selectors 。

请不要忘记导入对象以访问CSS_SELECTOR属性。我必须导入以下内容以自动化Chrome浏览器中的任务。

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.common.by import By

options = Options()
# options.add_experimental_option("detach", True)

driver = webdriver.Chrome(
    service=Service(ChromeDriverManager().install()),
     options=options
     )

driver.get("https://www.python.org/")
driver.maximize_window()

input = driver.find_element(By.CSS_SELECTOR,".documentation-widget p")

print(input)

driver.close()
driver.quit()
