Hi,
I am playing around with Web API and returning octet-stream for file download.
I was just wondering if there is no way to get the filestream when saving the ‘iwr’ in a variable?
This works:
Invoke-WebRequest $url -ContentType “application/json” -OutFile C:\temp\test.txt
But I can’t manage to get the file out if I save the ‘iwr’ in a variable?
$request = Invoke-WebRequest $url -ContentType “application/json”
Just because I’m curious 
What’s in your $request.Content property at that point? JSON text, or something else?
Hi Dave,
I have a byte array:
PS C:> $req.Content | gm
TypeName: System.Byte
I have tried to loop through every property/method I could fine.
That’s perfect. With a byte array, you can write to a file:
Set-Content -Path C:\temp\test.txt -Encoding Byte -Value $request.Content
@Dave, totally awesome! Couldn’t figure out to specify the encoding.
Tried this:
$req.Content > C:\temp\test.txt but that - ofcourse - just printet out the bytes in plain text.
Thanks
I like this. Is there an easy way to keep the file in memory instead of writing it to disk? I am using the following directives to download a ZIP file, but I would like to keep the file in memory instead of writing it to disk (just for my own satisfaction).
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$npppm = "https://github.com/$((Invoke-WebRequest -Uri "http://github.com/bruderstein/nppPluginManager/releases/latest").ParsedHtml.getElementsByTagName('li') | Where-Object {$_.className -eq 'd-block py-2'} | ForEach-Object { $_.getElementsByTagName('a') } | Where-Object { $_.pathName -match "^.*?x64.*" } | Select-Object -Expand pathName)"
Set-Content -Path ~\npppm.zip -Encoding Byte -Value (Invoke-WebRequest -Method Get -Uri $npppm).Content
So instead of Set-Conent writing to disk, it would just output the byte value so I could keep it in a PowerShell variable. Or even, I could pipe the result to
Expand-Archiveso that it writes the contents to disk without ever having the ZIP stored.
