API request

Hi All,

I have come-up with below script, however it is keep loading but nit giving me any results.

Can you please let me know if anything is missing in my script.

Script:

function GetXrfKey() {

  $alphabet = $Null; For ($a=97;$a -le 122;$a++) { $alphabet += ,[char][byte]$a }

  For ($loop=1; $loop -le 16; $loop++) {

    $key += ($alphabet | Get-Random)

  }

  return $key

}

$xrfKey = GetXrfKey

$cert=Get-ChildItem -Path "cert:\CurrentUser\My" | where {$_.Subject -like "*QlikClient*"}

$url="http://127.0.0.1:4747/qrs/app/about?xrefkey=" + $xrfKey

$hrds=@{"x-qlik-xrfkey"=$xrfKey

"X-Qlik-User"='UserDirectory=DESKTOP-A7R270Q;UserId=GIS-11'}

Invoke-RestMethod -Method "get" -Uri $url -CertificateThumbprint $cert.Thumbprint -Headers $hrds

I am quite new to JS, but shouldn't this line:

$xrfKey = GetXrfKey

be changed to:

$xrfKey = GetXrfKey();

So that way you call the function?

[rangam_s]

Thanks for request, I am getting the expected output under $xrfKey  even without ().

Well I am not good enough in JS to debug this, but I would change this topic from:
Assumed Answered.

And I would indent the code correctly, so it's easier to read for the people that do know enough JS.

My only other suggestion would be to use the debugger / console.log() and just go through it step by step, but you probably already did that.

Sorry I couldn't help any further!

No Problem, but I found an answer for this query wherein I am not passing the content type in my invoke request.

Helping hand is always helpful, no need to apologize

Thank you very much for stepping forward and helping me ...

Hey Rangam,

I am bit confused by some of the choices that were made here. Here's revamped code which is running clean:

function GetXrfKey() {
  $alphabet = $Null; For ($a=97;$a -le 122;$a++) { $alphabet += ,[char][byte]$a }
  For ($loop=1; $loop -le 16; $loop++) {
    $key += ($alphabet | Get-Random)
  }
  return $key
}
$xrfKey = GetXrfKey
$cert=Get-ChildItem -Path "cert:\CurrentUser\My" | where {$_.Subject -like "*QlikClient*"}
$Data = Get-Content C:\ProgramData\Qlik\Sense\Host.cfg
$FQDN = [System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String($($Data)))
$url="https://$($FQDN):4242/qrs/about?xrfkey=" + $xrfKey
$hdrs = @{}
$hdrs.Add("x-qlik-xrfkey", $xrfKey)
$hdrs.Add("X-Qlik-User", "UserDirectory=INTERNAL; UserId=sa_api")
Invoke-RestMethod -Method "get" -Uri $url -CertificateThumbprint $cert.Thumbprint -Headers $hdrs

Some notes:

• Lines 10-12 are me using a method for scraping the configured hostname from the Host.cfg
• Line 12, you:
  • Are hitting 4747 which is the QES port, not the QRS port
  • Have a bad path. /qrs/about rather than /qrs/app/about
  • Have misspelled the xrfkey param
• Lines 13-15
  • I am adding each header specifically so it's clear how to add more as needed.

Hope that helps.
