Powershell Download a Collector
I've been working on a Powershell method to download a collector. I'm to the point where I've got content, but no matter how I write the file ($content > "lm.exe", $content | Out-File "lm.exe" (tried all the encoding options), or $content | Set-Content lm.exe) the resulting file will not execute. https://XXXX.logicmonitor.com/santaba/rest/setting/collectors/1005/installers/Win64?collectorSize=small $i = Get-LMCollectorInstaller -Account "XXXX" -CollectorId 1005 -CollectorSize small -Platform Win64 -Verbose VERBOSE: Verb:GET Epoch:1578077331506 Data: resourcePath:/setting/collectors/1005/installers/Win64 VERBOSE: Url: https://XXXX.logicmonitor.com/santaba/rest/setting/collectors/1005/installers/Win64?collectorSize=small, Method: GET, Header: System.Collections.Generic.Dictionary`2[System.String,System.String] VERBOSE: GET https://XXXX.logicmonitor.com/santaba/rest/setting/collectors/1005/installers/Win64?collectorSize=small with 0-byte payload VERBOSE: received -1-byte response of content type application/binary $i | Set-Content .\Desktop\lm.exe $i > .\Desktop\lm.exe Running both yields a "This app can't run on your PC" popup on Windows 10 and Windows Server 2016. The file sizes are _almost_ the same (291,802,970 [not working] vs. 291,802,968 [working]) which makes me think it's an encoding issue, but I also tried all the Out-File encoding options with the same results. $httpVerb = "GET" $resourcePath = "/setting/collectors/$CollectorId/installers/$Platform" $Query = "?collectorSize=$CollectorSize" [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 <# request details #> $httpVerb = $Verb $resourcePath = $Path <# Construct URL #> $url = 'https://' + $Account + '.logicmonitor.com/santaba/rest' + $resourcePath + $Query <# Get current time in milliseconds #> $epoch = [Math]::Round((New-TimeSpan -start (Get-Date -Date "1/1/1970") -end (Get-Date).ToUniversalTime()).TotalMilliseconds) <# Concatenate Request Details #> Write-Verbose "Verb:$httpVerb Epoch:$epoch Data:$Data resourcePath:$resourcePath" $requestVars = $httpVerb + $epoch + $Data + $resourcePath <# Construct Signature #> $hmac = New-Object System.Security.Cryptography.HMACSHA256 $hmac.Key = [Text.Encoding]::UTF8.GetBytes($AccessKey) $signatureBytes = $hmac.ComputeHash([Text.Encoding]::UTF8.GetBytes($requestVars)) $signatureHex = [System.BitConverter]::ToString($signatureBytes) -replace '-' $signature = [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($signatureHex.ToLower())) <# Construct Headers #> $auth = 'LMv1 ' + $AccessId + ':' + $signature + ':' + $epoch $headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]" $headers.Add("Authorization",$auth) $headers.Add("Content-Type",'application/json') $response = Invoke-RestMethod -Uri $url -Method $Verb -Header $headers -ContentType "application/json" Write-Output $responseSolved73Views1like3Comments
