用于发送批量 whatsapp 消息的代码 python/selenium - 始终无法找到文本框的元素

Question

查看了许多选项和其他代码。下面代码中的所有内容都运行顺利，直到 whatsapp 输入框被调用：

*input_box = driver.find_element_by_xpath('//*[@id="main"]/footer/div[1]/div[2]/div/div[2]')*

我也调整为：

*input_box = driver.find_element(By.XPATH, '//*@id="main"]/footer/div[1]/div[2]/div/div[2]')*

没有任何成功。我收到以下错误：

Klaas Malan *(my contact)*
As jy hierdie teks kry, dan werk die program wat ek vir Heiko skrywe. *(Message in Afrikaans)*

有没有人有建议或愿意分享他们的代码？最良好的祝愿，伙计们。我是 Python 的新手，是纳米比亚的一名农民，我的目标是向我的每个牛买家发送单独的消息，感谢他们。荣格

根据消息框的html，我可以找到以下内容：

<div title="Type a message" role="textbox" class="_13NKt copyable-text selectable-text" contenteditable="true" data-tab="10" dir="ltr" spellcheck="true"></div>

Answer 1

您试过通过文本查找元素吗？

input_box = driver.find_element_by_xpath('//*[text()="Type a message"]')

或者您可以使用 contains() 来查找元素：

input_box = driver.find_element_by_xpath('//*[contains(@class, "copyable-text selectable-text")]'

Answer 2

好的，抱歉。如果我这样做，@jfleach 建议有效：

input_box = driver.find_elements(By.XPATH, '//*[text() = "Type a message"]')

当然，现在又出现了一个新问题：

  File "C:\Users\aegju\.00. Python Projects\Shantanusk Whatsapp\Bulk Shanatanusk.py", line 64, in <module>
targets = readContacts("./contacts-message.xlsx")

  File "C:\Users\aegju\.00. Python Projects\Shantanusk Whatsapp\Bulk Shanatanusk.py", line 50, in readContacts
input_box.send_keys(ch)

AttributeError: 'list' object has no attribute 'send_keys'

或者，作为新手，我应该 post 一个新问题吗？
