无法保持对 Selenium Python 驱动程序中元素的关注

我试图通过 python 控制网络来运行脚本并下载相应的 csv 文件。

以下是网页的外观，其中包含仪表板菜单，可单击“搜索”其他按钮。单击“搜索”按钮后，它会显示一个“搜索”文本框，可以在其中输入代码并按 Enter 键运行。

现在我需要找到这个搜索框的元素。从 Chrome 中的 Inspect 来看，如下所示：

所以我使用了以下代码。在从文本文件复制代码并将其发送到该搜索框之前，我还使用操作将焦点保持在搜索框上。

def run_code():

""" Function to copy the code in Search and run it

"""

search_button=driver.find_element_by_link_text("Search")
search_button.click()

time.sleep(2)

with open('data_download_code.txt', 'r') as f:
    code_file= f.read()

content_box=driver.find_element_by_class_name("ace_content")

# Getting the focus on the element
actions=ActionChains(driver)
actions.move_to_element(content_box)
actions.click()

content_box.send_keys(code_file,Keys.ENTER)
#content_box.submit()

但是，它会引发焦点不在元素上的错误。

我不确定我是否从附加的 html 文件中获得了正确的搜索元素选择器，或者这只是一些焦点问题。我确实在那里使用了 Actions 类来获得焦点。

我希望代码读取txt文件中的文本并将其发送到搜索框，然后按回车键运行它。

WebDriverException: Message: unknown error: cannot focus element
  (Session info: chrome=71.0.3578.98)

编辑：选择器的额外 html 详细信息

Edit 3:

因此，我能够获取搜索元素，并且它能够从 txt 文件复制代码并在搜索框中输入，但我发现它无法正确复制整个代码，因此会出现错误。请参阅随附的完整代码以及复制了多少内容。

Edit4:

从txt文件中读取的代码也是读取\n。因此该字符串中有 \n ，我猜想当发送到 WebDriver 在搜索框中运行时可能会导致问题。可以阅读上面编辑中的代码吗？

您应该将密钥发送至input领域，但不是父母div。请尝试以下操作：

content_box = driver.find_element_by_css_selector("div.ace_content input")
content_box.send_keys(code_file, Keys.ENTER)

or

content_box = driver.find_element_by_class_name('ace_text-input')
content_box.send_keys(code_file, Keys.ENTER)

另请注意，您很可能不需要使用Actions
