推荐答案
解决方案是非常具体的浏览器。对于Chrome，您可以告诉Chrome在哪里下载文件。选择一个新文件夹允许您监视下载的状态。此外，由于您正在下载PDF，因此禁用PDF插件是为了防止PDF被显示而不是下载。这是一个在我的机器上使用简单的页面和PDF文件的测试。
The solution is very browser specific. For Chrome, you can tell Chrome where to download files. Choosing a new folder allows you to monitor the status of the download. Also, since you are downloading a PDF, disabling the PDF plugin is necessary to prevent the PDF from being displayed instead of downloaded. Here is a test that worked on my machine using a simple page and PDF file.
*** Settings ***
Test Teardown Close All Browsers
Library Selenium2Library
Library OperatingSystem
*** Test Cases ***
Download PDF
# create unique folder
${now} Get Time epoch
${download directory} Join Path ${OUTPUT DIR} downloads_${now}
Create Directory ${download directory}
${chrome options}= Evaluate sys.modules['selenium.webdriver'].ChromeOptions() sys, selenium.webdriver
# list of plugins to disable. disabling PDF Viewer is necessary so that PDFs are saved rather than displayed
${disabled} Create List Chrome PDF Viewer
${prefs} Create Dictionary download.default_directory=${download directory} plugins.plugins_disabled=${disabled}
Call Method ${chrome options} add_experimental_option prefs ${prefs}
Create Webdriver Chrome chrome_options=${chrome options}
Goto http://localhost/download.html
Click Link link # downloads a file
# wait for download to finish
