使用Ruby中的selenium webdriver检查文件是否已在单击时下载

require 'selenium-webdriver'
require 'fileutils'

driver = Selenium::WebDriver.for :chrome
driver.get 'https://example.com'  # 替换为目标网页的URL

download_link = driver.find_element(:id, 'download-link')  # 替换为实际下载链接的元素定位方式
download_url = download_link.attribute('href')

download_directory = '/path/to/download/directory'  # 替换为实际的下载目录
FileUtils.mkdir_p(download_directory) unless File.directory?(download_directory)

driver.get download_url
sleep 1  # 等待下载完成

# 获取下载的文件名
downloaded_file = Dir.glob(File.join(download_directory, '*')).max_by {|f| File.mtime(f)}

if File.exist?(downloaded_file)
  puts '文件已成功下载'
else
  puts '文件下载失败'
end
