Question

我已尝试过此页面中的方法： 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')

但是我收到以下错误：

Traceback (most recent call last):
  File "test.py", line 110, in <module>
    upload_students_results('Surname, Name')
  File "test.py", line 91, in upload_students_results
    file_button.send_keys('/Users/home/Downloads/1-Students-and-Parent-Email.csv')

Answer 1

问题是 - 您正在向div元素发送密钥，该元素不是可互动的＆＃34;，不接受密钥 - 因此＆＃34;无法关注元素＆＃34;错误。

您已关联的解决方案背后的想法是将密钥发送到负责文件上传的input type="file"元素。在HTML中找到此元素并将密钥发送给它。

请注意，此元素可能不可见。在这种情况下，您应首先make it visible send_keys()才能正常工作。

好的，现在我们至少知道哪个元素是我们想要的元素：

<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/和，检查此元素是否在iframe内 - 如果是，则需要切换到iframe的上下文，然后才执行元素搜索。

当我将文件路径作为字符串插入时，我遇到了同样的问题。这是有效的：{"requestId":"73f40519-87c8-4037-a9fc-41be82b3b227","status":{"message":"","code":200,"attributes":{}},"result":{"data":[[20608,28920,32912,106744,123080,135200,139296,143464,143488,143560,151584,155688,155752,159784,188520,254016,282688,286968,311360,323832,348408,4344,835648,8336,1343616,12352]],"meta":{}}}
