代码Python/Selenium发送批量WhatsApp消息 - 不断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顺利运行，直到调用WhatsApp输入框：

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

我还将其调整为：

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

没有任何成功。我会收到以下错误：

有没有建议或愿意共享其代码的人？ 最好的祝愿，伙计们。我是Python和纳米比亚的一个农民的新手，我的目标是向我的每位牛买家致敬。 Emil Jung

这是我可以从消息框的HTML方面找到的：

<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

您是否尝试通过文本找到元素？

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

或者，您可以使用contains（）查找元素：

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

Answer 2

好，很抱歉。如果我这样做，@Jfleach建议奏效了：

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

当然，一个新的问题会弹出：

  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'

或者是新事物，我应该发布一个新问题吗？

driver.find_element（
“ xpath”，'//*[@id =“ main”]/脚步/div [1]/div/div/span [2]/div/div/div [2]/div [1]/div/div/div/div/p'） .send_keys（keys.enter）
