我在尝试发送带有selenium的whatsapp时遇到错误和回溯

Question

我正试图发送一个带有selenium和chromedriver的whatsapp，但是当我运行代码时，我得到一个错误和一个回溯。

我已经尝试了我能做的一切（我对python略知一二，我在学习，我对selenium一无所知，但我必须尽快让它工作起来），我也尝试了很多，尝试了很多东西，但我无法让它工作。

如果有人能帮助我，我将非常感激

错误是：

[WDM] - ====== WebDriver manager ====== [WDM] - Current google-chrome version is 89.0.4389 [WDM] - Get LATEST driver version for 89.0.4389 [WDM] - Driver [C:\Users\Crist.wdm\drivers\chromedriver\win32\89.0.4389.23\chromedriver.exe] found in cache

代码是这样的（这正是让它工作所需要的）：

contact = ["cristobal de toro", "cristobal", "gonzalo molina"]
text = "Hey, this message was sent using Selenium"
driver = webdriver.Chrome(ChromeDriverManager().install())
driver.get("https://web.whatsapp.com")
print("Scan QR Code, And then Enter")
input()
print("Logged In")
inp_xpath_search = "//input[@title='Search or start new chat']"
input_box_search = WebDriverWait(driver,50).until(lambda driver: driver.find_element_by_xpath(inp_xpath_search))
input_box_search.click()
time.sleep(2)
input_box_search.send_keys(contact)
time.sleep(2)
selected_contact = driver.find_element_by_xpath("//span[@title='"+contact+"']")
selected_contact.click()
inp_xpath = '//div[@class="_2S1VP copyable-text selectable-text"][@contenteditable="true"][@data-tab="1"]'
input_box = driver.find_element_by_xpath(inp_xpath)
time.sleep(2)
input_box.send_keys(text + Keys.ENTER)
time.sleep(2)
driver.quit()

因此，我查看了whatsapp web版本的代码，似乎每次刷新页面时，每个联系人都会被分配到一个随机uid（至少在我的情况下是这样）。这意味着您需要使用pyautogui之类的工具来单击页面上可预测的位置。至于实际的输入区域，它甚至不是一个输入，所以selenium在这种情况下不起作用。我只是写了一些示例代码来说明这是如何工作的——我在一台13英寸的笔记本电脑上，所以你可能需要用

pyautogui.position()

使用以下软件安装pyautogui：

python3 -m pip install pyautogui

下面是示例代码：

import pyautogui
import os
import time

FIRSTX = 155
FIRSTY = 268

INPUTX = 605
INPUTY = 696






os.system('open https://web.whatsapp.com/')
time.sleep(7)

#Click on the first person in your contacts
pyautogui.click(x=FIRSTX, y=FIRSTY)
time.sleep(1)


#Click the input
pyautogui.click(x=INPUTX, y=INPUTY)
pyautogui.write("Your Message")
pyautogui.press('enter')
