Why is PowerShell not able to send proper Crumb?

Question

My PowerShell script:

$Params = @{
    uri     = \"http://${API_URL}:${API_Port}/crumbIssuer/api/json\";
    Method  = \'Get\';
    Headers = @{
        Auth         


        

Answer 1

I modified the code as follows and it worked. Not sure though why previous code was throwing error.

$API_User = "admin"
$API_Pass = "password"
$API_URL = "localhost"
$API_Port = "8080"
$API_Job = "test01"

$h = @{}
$h.Add('Authorization', 'Basic ' + [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes("$(${API_User}):$(${API_Pass})")))

$Params = @{uri = "http://${API_URL}:${API_Port}/crumbIssuer/api/json";
        Method = 'Get';
        Headers = $h;}
$API_Crumb = Invoke-RestMethod @Params

$h.Add('Jenkins-Crumb', $API_Crumb.crumb)
$Params['uri'] = "http://${API_URL}:${API_Port}/job/${API_Job}/build"
$Params['Method'] = 'Post'
$Params['Headers'] = $h

Invoke-RestMethod @Params
