function New-JiraSession { <# .Synopsis Creates a persistent JIRA authenticated session which can be used by other PSJira functions .DESCRIPTION This function creates a persistent, authenticated session in to JIRA which can be used by all other PSJira functions instead of explicitly passing parameters. This removes the need to use the -Credential parameter constantly for each function call. This is the equivalent of a browser cookie saving login information. Session data is stored in this module's PrivateData; it is not necessary to supply it to each subsequent function. .EXAMPLE New-JiraSession -Credential (Get-Credential jiraUsername) Get-JiraIssue TEST-01 Creates a Jira session for jiraUsername. The following Get-JiraIssue is run using the saved session for jiraUsername. .INPUTS [PSCredential] The credentials to use to create the Jira session .OUTPUTS [PSJira.Session] An object representing the Jira session #> [CmdletBinding()] param( # Credentials to use for the persistent session [Parameter(Mandatory = $true, Position = 0)] [System.Management.Automation.PSCredential] $Credential ) begin { try { Write-Debug "[New-JiraSession] Reading Jira server from config file" $server = Get-JiraConfigServer -ConfigFile $ConfigFile -ErrorAction Stop } catch { $err = $_ Write-Debug "[New-JiraSession] Encountered an error reading configuration data." throw $err } $uri = "$server/rest/auth/1/session" $headers = @{ 'Content-Type' = 'application/json'; } } process { $hashtable = @{ 'username' = $Credential.UserName; 'password' = $Credential.GetNetworkCredential().Password; } $json = ConvertTo-Json -InputObject $hashtable Write-Debug "[New-JiraSession] Created JSON syntax in variable `$json."
