我已经尝试过此页面的方法: Upload file with Selenium in Python
代码:
file_button = browser.find_element_by_id('fileUploadProxy')
file_button.send_keys('/Users/home/Downloads/1-Students-and-Parent-Email.csv')
但我收到以下错误:
Traceback (most recent call last):

最佳答案
问题是 - 您正在将 key 发送到不可“交互”的 div
元素,该元素不接受 key - 因此出现“无法聚焦元素”错误。
您链接的解决方案背后的想法是将 key 发送到负责文件上传的 input
元素,其中 type="file"
。在 HTML 中找到此元素并向其发送 key 。
请注意,该元素可能是不可见的。在这种情况下,您应该首先make it visible让 send_keys()
正常工作。
更新:
好吧,现在我们至少知道哪个元素是我们想要的:
<input type="file" name="fileToUpload" id="fileToUpload2" class="fileToUpload">
由于您无法找到此元素,请尝试 waiting for it :
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
file_upload = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.ID, "fileToUpload2"))
)
file_upload.send_keys('/Users/home/Downloads/1-Students-and-Parent-Email.csv')
或者/并且,检查此元素是否位于 iframe
内 - 如果是,您需要切换到 iframe
的上下文,然后才执行元素搜索。
