如何使用selenium上传随机文件？

from selenium import webdriver
import os
import random
import string

# 设置驱动程序路径
driver_path = "path_to_driver"
# 初始化浏览器驱动
driver = webdriver.Chrome(driver_path)

# 导航到包含文件上传表单的网页
driver.get("https://example.com/upload")

# 定位文件上传表单元素
upload_input = driver.find_element_by_id("file-upload")

# 生成随机文件名
file_name = ''.join(random.choices(string.ascii_lowercase + string.digits, k=8))
file_path = os.path.join(os.getcwd(), file_name)

# 创建一个随机文件并保存到本地
with open(file_path, 'w') as file:
    file.write("This is a random file.")

# 将随机文件路径传递给文件上传表单元素
upload_input.send_keys(file_path)

# 提交文件上传表单
submit_button = driver.find_element_by_id("submit-button")
submit_button.click()

# 关闭浏览器
driver.quit()

# 删除本地生成的随机文件
os.remove(file_path)
