问题描述
我第一次使用Powershell.我已经学会了如何使用以下代码使用网络客户端下载文件.
I'm using powershell for the first time. I've learned how to download files using a webclient, using the following code.
$client = New-Object System.NET.Webclient
$client.DownloadFile( $url, $path )
对于我最终想要做的事情来说，这似乎工作得很好，那就是一次从一个网页上下载多个文件.我在一个网站上尝试了该网站，该网站的文件格式设置为.pfva文件，并以PDF格式打开.没问题.这也是一个受密码保护的网站.
This seems to work nicely for what I am trying to eventually do, which is download multiple files from a web page at one time. I tried this on a site, which has its files formatted as .pfva files, which are opened as a PDF. no problem. This was a password protected site too.
因此，转到我实际上想在其上使用的网站.同样，该站点需要登录，尽管我只是在浏览器上登录然后运行Webclient.可能是为什么我从不需要在命令脚本中通过身份验证....
So moving to the site that I actually want to use it on. Again, a site requiring a log in, although I just sign in on my browser and then run the webclient. Probably why I never have to pass authentication in the command script....
此站点的文件格式为.aspx文件.它们将以PDF文件形式打开.我只需单击该文件，然后保存或打开，它自然就可以作为PDF文件工作.但是当我使用webclient.download文件时，它会下载到正确的位置...但是尝试打开它时出现错误.
This site's files are formatted as .aspx files. They are to be opened as PDF files. I can simply click on the file, save or open, and it works naturally as a PDF file. But when I use the webclient.download file, it downloads to the right spot...but I get an error when trying to open it.
"Adobe无法打开文件.文件编码不正确" ...类似这些内容.我上班了，现在无法收到消息.下载的网址采用以下格式:.....
"Adobe can't open file. It was not coded properly" ...something along those lines. I can't get the message up now because I'm at work. The URL for the downloads are in the following format.....

为什么不打开！！！有没有解决的办法.任何帮助，将不胜感激.谢谢！.
Why won't it open!?! Is there a way around this. Any help would be appreciated. Thank you!.
哦，顺便说一句，我将$ path设置为计算机目录中的.PDF文件...因为我读到应该提供文件路径，而不仅仅是目录.
OH btw, I set the $path to a .PDF file in a directory on my computer...because I read that a path to a file should be provided, and not just a directory.
推荐答案
在大多数情况下，您的脚本看起来可以正常工作.
Looks like your script works in the most of cases.
我发现此页面，告诉用户代理HTTP标头字段对于服务器很重要，因此请尝试以下操作:
I found this page, telling that user agent HTTP header field can be important for server, so try this one:
$userAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2;)"
$url = "https://www.adobe.com/enterprise/pdfs/pdfarchiving.pdf"
$path = "c:\test.pdf"
$client = New-Object System.NET.Webclient
$client.Headers.Add("user-agent", $userAgent)
$client.DownloadFile( $url, $path )
