使用 Selenium 和 Python 的 Whatsapp 自动化错误

Question

我尝试使用 selenium 在 whatsapp 中向我的朋友发送消息。我下载了适用于 windows 的最新版本的 chromedriver，当我运行代码时，whatsapp web 已打开但消息未发送。这是我的代码和我遇到的错误：-

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

# Replace below path with the absolute path
# to chromedriver in your computer
*driver = webdriver.Chrome(executable_path=r'D:\Whatsapp Automation\chromedriver.exe')

driver.get("https://web.whatsapp.com/")
wait = WebDriverWait(driver, 600)

# Replace 'Friend's Name' with the name of your friend
# or the name of a group
target = "Friend's name"

# Replace the below string with your own message
string = "Hii"

x_arg = '//span[contains(@title,' + target + ')]'
group_title = wait.until(EC.presence_of_element_located((
    By.XPATH, x_arg)))
group_title.click()
inp_xpath = '//div[@class="input"][@dir="auto"][@data-tab="1"]'
input_box = wait.until(EC.presence_of_element_located((
    By.XPATH, inp_xpath)))
for i in range(100):
    input_box.send_keys(string + Keys.ENTER)
    time.sleep(1)

这是我得到的调试文件

我从https://chromedriver.storage.googleapis.com/index.html?path=87.0.4280.88/下载了chromedriver

我已经使用硒做到了这一点。 我制作了一个whatsapp bot，当它收到任何人的任何新消息时，它会自动发送消息。

检查以下代码并尝试使用它来完成向某人发送消息的工作。

from selenium import webdriver
import time

try:
    driver = webdriver.Chrome(executable_path=r'D:\Whatsapp Automation\chromedriver.exe')
except:
    driver = webdriver.Chrome(ChromeDriverManager().install())       # This will install the updated chromedriver automatically.

driver.get("https://web.whatsapp.com")
time.sleep(25) # For scan the qr code from the mobile phone to connect.
# Plese make sure that you have done the qr code scan successful.
confirm = int(input("Press 1 to proceed if sucessfully login or press 0 for retry : "))

if confirm == 1:
   print("Continuing...")
elif confirm == 0:
   driver.close()
   exit()
else:
   print("Sorry Please Try again")
   driver.close()
   exit()

'''
while True:
    # Here you can handle the received message and can send message to any selected person. Or you can follow my way to reply each person on their new message.
    send_message(driver)
'''

def send_message(chrome_browser):
    print("Starting Sending_msg")
    user_name_list = ['My Bot +1']  # Add the all users name in the list to whom you want to sent message.

    for user_name in user_name_list:
        try:
            # Select for the title having user name
            user = chrome_browser.find_element_by_xpath('//span[@title="{}"]'.format(user_name))
            user.click()
            time.sleep(1)
        except NoSuchElementException as se:
            print("Error : {}\nCause of Error : {}\n Line number : {}".format(sys.exc_info()[0], sys.exc_info()[1], sys.exc_info()[2].tb_lineno))
            print(se)
            new_chat(user_name, chrome_browser)

        # Typing message into message box
        time.sleep(1)
        
        message_input_box = chrome_browser.find_element_by_xpath('//div[@class="p3_M1 _1YbbN"]')
        message_box.send_keys('Hey, I am your whatsapp bot :)')
      
        time.sleep(1)

        # Click on send button
        try:
            message_box = chrome_browser.find_element_by_xpath('//button[@class="_4sWnG"]')
            message_box.click()
        except:
            print("Error : {}\nCause of Error : {}\n Line number : {}".format(sys.exc_info()[0], sys.exc_info()[1], sys.exc_info()[2].tb_lineno))
            time.sleep(1)
            message_box = chrome_browser.find_element_by_xpath('//button[@class="_4sWnG"]')
            message_box.click()

        time.sleep(2)


send_message(driver)

节点：我不确定 whatsapp-web 是否再次更改了其 Web 元素类名称。如果遇到与找不到此类元素相关的任何错误，请检查 whatsapp Web 元素类名称并对其进行检查并在代码中进行更新。
