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()

错误来自上一个函数navigatePagePostAria((测线将是action.send_keys(keys.BACK_SPACE(

错误：

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

这两条线是最重要的，就像导航一样

1.actions.send_keys(keys.BACK_SPACE(

2.actions.send_keys(keys.TAB*4(

我用它作为x路径的替代品，因为facebook非常动态，它每分钟都会改变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)

因此，现在当您调用actions.send_keys(Keys.BACK_SPACE)时，解释器会认为您调用的是actions方法，而不是其中启动的actions对象。
我建议您将此方法定义为以下

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

或者最好根本不定义这个方法，因为这并不是您要调用多次的真正方法
chrome_options和driver方法相同
没有必要将它们定义为方法，因为这些方法不是可重用的方法，它最好是一个平面代码，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()

我还将driver.get("https://facebook.com")迁移到了login方法中，因为这更属于selenium网络驱动程序本身的基本初始化
