Powershell wait until after file download to continue script

Question

$x = Invoke-RestMethod -Method "Get" -uri $url -Headers $get_headers 
**Start-Process "chrome.exe" $x.url**
Start-Sleep -s 10

Hello,

I am using the above to download a file via chrome. Is it possible to wait until the file download is complete to continue the script instead of sleeping or implementing an incremental retry function.

Thank you

have you tried using Start-Process `"chrome.exe" $x.url -wait`; Also why not just do another `Invoke-Restmethod` and save the file? — ArcSet, Feb 24 '20 at 15:44
unfortunately -wait did not work. Invoke-RestMethod -outfile seems to be working quite well. Thanks for the response. — Alex, Feb 24 '20 at 20:36

So lets talk about what i see and ways to make it better

$x = Invoke-RestMethod -Method "Get" -uri $url -Headers $get_headers 
Start-Process "chrome.exe" $x.url
Start-Sleep -s 10

Well you can save using the Invoke-RestMethod

Here is a example

Invoke-RestMethod "http://www.peoplelikeus.org/piccies/codpaste/codpaste-teachingpack.pdf" -OutFile "C:\codpaste-teachingpack.pdf"

In your case this might work.

$x = Invoke-RestMethod $url -Headers $get_headers 
Invoke-RestMethod $x.url -OutFile "C:\SomeTypeOfFile.Txt"

The Invoke-RestMethod will wait until it is complete to move on in the code.

Thank you for your help. Invoke-RestMethod $x.url -OutFile "C:\SomeTypeOfFile.Txt" is working as intended. — Alex, Feb 24 '20 at 20:37

FYI (putting this here as it is too long for a normal comment), here are 3 other ways, that you could have done this:

$url = "http://mirror.internode.on.net/pub/test/10meg.test"
$output = "$PSScriptRoot\10meg.test"
$start_time = Get-Date


# 1. Invoke-WebRequest

Invoke-WebRequest -Uri $url -OutFile $output
"Time taken: $((Get-Date).Subtract($start_time).Seconds) second(s)"

# 2. System.Net.WebClient

(New-Object System.Net.WebClient).DownloadFile($url, $output)
"Time taken: $((Get-Date).Subtract($start_time).Seconds) second(s)"

# 3. Start-BitsTransfer

Start-BitsTransfer -Source $url -Destination $output -Asynchronous
"Time taken: $((Get-Date).Subtract($start_time).Seconds) second(s)"
