问题
Ok, I am trying to download a file off of a web link that we use with powershell. I am downloading a zip file where the begining of the name is always the same, but the the middle part will change based off of the version number of the zip. I have been able to get the file to download when I use the fully qualified web address and have the file name hard coded into the script. I have tried every version of using the wild cards to get all the most common version of the zip, but it errors out saying that it can't find the file on there server. This is the code that I have already, and any help would be greatly appreciated since I feel like I am at a wall with it.
$url = 'http://blah/blah/blah/My File Name 11.1111.11.zip'
$localFileName = 'C:\temp\MYzip.zip'
Invoke-WebRequest $url -UseDefaultCredentials -OutFile $localFileName

If the site has directory browsing enabled (unlikely unless you have control of the site and can turn it on), you can do this:
$url = 'http://blah/blah/blah/'
$wr = iwr $url
$filename = $wr.Links.href | Where {$_ -match 'My File Name.*?\.zip'}
$wr = iwr "$url/$filename"
If the site doesn't have directory browsing enabled then surely it has a page with a link to the ZIP file on it. Download that page and use the same $wr.Links.href trick to get all the links and look for the one that matches "My File Name.*?.zip".
