Question

我试图通过python控制网络以运行脚本并下载相应的csv文件。

这是使用仪表板菜单单击“搜索”其他按钮的网页外观。单击“搜索”按钮后，将显示一个“搜索”文本框，您可以在其中输入代码并按Enter键运行。

现在，我需要找到此搜索框的元素。从Chrome中的Inspect中，如下所示：

因此，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，我还使用了动作来使焦点集中在搜索框上。

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，它将引发焦点错误而不是元素错误。

我不确定是否从所附的html文件中找到了用于搜索的正确元素选择器，否则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Enter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

因此，我能够获取Search元素，并且能够从txt文件复制代码并在搜索框中输入内容，但我发现它无法正确复制整个代码，因此会出现错误。请查看随附的完整代码以及复制了多少代码。

Edit4：

从txt文件读取的代码也为\ n。因此该字符串中包含\ n，我想这可能会导致在发送到WebDriver以便在搜索框中运行时引起问题。可以读取上面编辑中的代码吗？

Answer 1

您应该将密钥发送到input字段，而不是父密钥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)

或

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

还请注意，您很可能不需要使用Actions

Answer 2

content_box=driver.find_element_by_class_name("ace_content")

此代码将导致content_box为“ div”元素。您不能将键发送到div元素。检查该div以查找“ textarea”或“ input”元素，并将其设置为content_box。

Answer 3

在@Andersson的回答（您应该接受顺便说一句，他确实解决了您的问题；）之外，让我帮助您从源文本中剥离\n。这段代码：

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

，read()方法，返回文件的原始值，并保留EOL（行尾）字符。但是：

code_file = f.read.splitlines()

，将以字符串列表的形式返回（在code_file中），每个列表成员在文件中占一行。现在的问题是-用什么替换EOL字符？我不熟悉其中的语言，因此由您决定。
假设它是一个分号;，这是将列表转换回字符串的方法：

code_file = ';'.join(code_file)

这将使用该字符作为分隔符将所有列表成员连接到一个字符串中。自然地，您只需将char替换为适用的内容：

code_file = ' '.join(code_file)    # a whitespace character
code_file = '\t'.join(code_file)   # a tab
code_file = '\\n'.join(code_file)  # a literal newline
code_file = 'whatever?'.join(code_file)    # you name it

所以最终形式是：

with open('data_download_code.txt', 'r') as f:
   code_file= f.readlines()
   code_file = ';'.join(code_file)
