Keys.BACK_SPACE 或 Keys.TAB 发送密钥在 facebook selenium python 上不起作用

Question

我正在编写一些硒代码来导航 Facebook。

import os
import time
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys


def driver():
    global driver
    driver = webdriver.Chrome("chromedriver.exe", chrome_options=chrome_options)
    driver.get("https://facebook.com")


def chrome_options():
    global chrome_options
    chrome_options = Options()
    chrome_options.add_argument("--start-maximized")
    chrome_options.add_argument('--profile-directory=Default')
    # chrome_options.add_argument("--user-data-dir=chrome-data")
    prefs = {"profile.default_content_setting_values.notifications": 2}
    chrome_options.add_experimental_option("prefs", prefs)
    chrome_options.add_argument('disable-infobars')
    chrome_options.add_experimental_option("useAutomationExtension", False)
    chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])


def actions():
    global actions
    actions = ActionChains(driver)


def login():
    try:
        # I use environment veriable  base on this tutorials https://www.youtube.com/watch?v=IolxqkL7cD8
        username = os.environ.get('my_facebook_username')
        password = os.environ.get('my_facebook_password')

        driver.find_element_by_name("email").send_keys(username)
        driver.find_element_by_name("pass").send_keys(password)
        driver.find_element_by_name("login").click()
        print(input("Press any Key: "))
        print("Login work Successfully ")

    except:
        pass


def navigatePagePostAria():
    sleepTime = 4
    implicitlyWaitTime = 20
    for i in range(2):
        driver.implicitly_wait(implicitlyWaitTime)
        actions.send_keys(Keys.BACK_SPACE)
        actions.send_keys(Keys.TAB * 4)
        time.sleep(sleepTime)
        actions.perform()
        print("Firast 10 tabs Working")

    actions.send_keys(Keys.TAB * 3)
    actions.send_keys(Keys.ENTER)
    actions.perform()
    print("Navigate Post area Successfully ")


chrome_options()
driver()
login()
driver.get("https://www.facebook.com/groups/402353916617590/permalink/1630582000461436/")
navigatePagePostAria()

错误来自最后一个函数 navigatePagePostAria() 行将是actions.send_keys(Keys.BACK_SPACE)

错误 ：

Traceback (most recent call last):
  File "K:\Project\Python\Miracle\groupPost.py", line 154, in <module>
    navigatePagePostAria()
  File "K:\Project\Python\Miracle\groupPost.py", line 63, in navigatePagePostAria
    actions.send_keys(Keys.BACK_SPACE)
AttributeError: 'function' object has no attribute 'send_keys'

这两行是最重要的导航

1.actions.send_keys(Keys.BACK_SPACE)

2.actions.send_keys(Keys.TAB * 4)

我用它作为 x 路径的替代方法 bechouse facebook 是非常动态的，它每分钟都会改变它的 x 路径。

这里的问题是您在方法中使用了误导性的名称。
您定义了以下方法

def actions():
    global actions
    actions = ActionChains(driver)

所以现在当你调用actions.send_keys(Keys.BACK_SPACE)解释器时认为你在调用那个actions方法，而不是actions在它内部启动的对象。
我建议你定义这个方法如下

def set_actions():
    global actions
    actions = ActionChains(driver)

甚至最好根本不定义此方法，因为这不是您要多次调用的真正方法。
同样约chrome_options和driver方法。
没有必要将它们定义为方法，因为它们不是可重用的方法，最好是平面代码，这样整个代码将如下所示：

import os
import time
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys

#Setting the chrome_options
global chrome_options
chrome_options = Options()
chrome_options.add_argument("--start-maximized")
chrome_options.add_argument('--profile-directory=Default')
# chrome_options.add_argument("--user-data-dir=chrome-data")
prefs = {"profile.default_content_setting_values.notifications": 2}
chrome_options.add_experimental_option("prefs", prefs)
chrome_options.add_argument('disable-infobars')
chrome_options.add_experimental_option("useAutomationExtension", False)
chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])

#Setting the Chrome Driver
global driver
driver = webdriver.Chrome("chromedriver.exe", chrome_options=chrome_options)

#Setting the Actions
global actions
actions = ActionChains(driver)


def login():
  driver.get("https://facebook.com")
    try:
        # I use environment variable  base on this tutorials https://www.youtube.com/watch?v=IolxqkL7cD8
        username = os.environ.get('my_facebook_username')
        password = os.environ.get('my_facebook_password')

        driver.find_element_by_name("email").send_keys(username)
        driver.find_element_by_name("pass").send_keys(password)
        driver.find_element_by_name("login").click()
        print(input("Press any Key: "))
        print("Login work Successfully ")

    except:
        pass


def navigatePagePostAria():
    sleepTime = 4
    implicitlyWaitTime = 20
    for i in range(2):
        driver.implicitly_wait(implicitlyWaitTime)
        actions.send_keys(Keys.BACK_SPACE)
        actions.send_keys(Keys.TAB * 4)
        time.sleep(sleepTime)
        actions.perform()
        print("Firast 10 tabs Working")

    actions.send_keys(Keys.TAB * 3)
    actions.send_keys(Keys.ENTER)
    actions.perform()
    print("Navigate Post area Successfully ")


login()
driver.get("https://www.facebook.com/groups/402353916617590/permalink/1630582000461436/")
navigatePagePostAria()

我还迁移driver.get("https://facebook.com")到login方法中，因为这更多地属于 selenium webdriver 本身的基本初始化
