function Get-JiraIssue { <# .Synopsis Returns information about an issue in JIRA. .DESCRIPTION This function obtains references to issues in JIRA. This function can be used to directly query JIRA for a specific issue key or internal issue ID. It can also be used to query JIRA for issues matching a specific criteria using JQL (Jira Query Language). For more details on JQL syntax, see this articla from Atlassian: https://confluence.atlassian.com/display/JIRA/Advanced+Searching Output from this function can be piped to various other functions in this module, including Set-JiraIssue, Add-JiraIssueComment, and Invoke-JiraIssueTransition. .EXAMPLE Get-JiraIssue -Key TEST-001 This example returns a reference to JIRA issue TEST-001. .EXAMPLE Get-JiraIssue "TEST-002" | Add-JiraIssueComment "Test comment from PowerShell" This example illustrates pipeline use from Get-JiraIssue to Add-JiraIssueComment. .EXAMPLE Get-JiraIssue -Query 'project = "TEST" AND created >= -5d' This example illustrates using the Query parameter and JQL syntax to query Jira for matching issues. .INPUTS This function can accept PSJira.Issue objects, Strings, or Objects via the pipeline. * If a PSJira.Issue object is passed, this function returns a new reference to the same issue. * If a String is passed, this function searches for an issue with that issue key or internal ID. * If an Object is passed, this function invokes its ToString() method and treats it as a String. .OUTPUTS This function outputs the PSJira.Issue object retrieved. .NOTES This function requires either the -Credential parameter to be passed or a persistent JIRA session. See New-JiraSession for more details. If neither are supplied, this function will run with anonymous access to JIRA. #> [CmdletBinding(DefaultParameterSetName = 'ByIssueKey')] param( [Parameter(ParameterSetName = 'ByIssueKey', Mandatory = $true, Position = 0)] [ValidateNotNullOrEmpty()] [String[]] $Key, [Parameter(ParameterSetName = 'ByInputObject', Mandatory = $true, Position = 0)] [Object[]] $InputObject, [Parameter(ParameterSetName = 'ByJQL', Mandatory = $true)] [Alias('JQL')] [String] $Query, [Parameter(ParameterSetName = 'ByFilter')] [Object] $Filter, [Parameter(ParameterSetName = 'ByJQL')] [Parameter(ParameterSetName = 'ByFilter')] [Int] $MaxResults = 50, # Credentials to use to connect to Jira [Parameter(Mandatory = $false)] [System.Management.Automation.PSCredential] $Credential ) begin { Write-Debug "[Get-JiraIssue] Reading server from config file" $server = Get-JiraConfigServer -ConfigFile $ConfigFile -ErrorAction Stop Write-Debug "[Get-JiraIssue] ParameterSetName=$($PSCmdlet.ParameterSetName)" } process { if ($PSCmdlet.ParameterSetName -eq 'ByIssueKey') { foreach ($k in $Key) { Write-Debug "[Get-JiraIssue] Processing issue key [$k]" $issueURL = "$($server)/rest/api/latest/issue/${k}?expand=transitions" Write-Debug "[Get-JiraIssue] Preparing for blastoff!" $result = Invoke-JiraMethod -Method Get -URI $issueURL -Credential $Credential if ($result) { Write-Debug "[Get-JiraIssue] Converting REST result to Jira object" $obj = ConvertTo-JiraIssue -InputObject $result Write-Debug "[Get-JiraIssue] Outputting result" Write-Output $obj } else { Write-Debug "[Get-JiraIssue] Invoke-JiraMethod returned no results to output." } } } elseif ($PSCmdlet.ParameterSetName -eq 'ByInputObject') { foreach ($i in $InputObject) { Write-Debug "[Get-JiraIssue] Processing InputObject [$i]" if ((Get-Member -InputObject $i).TypeName -eq 'PSJira.Issue') { Write-Debug "[Get-JiraIssue] Issue parameter is a PSJira.Issue object" $issueKey = $i.Key } else { $issueKey = $i.ToString() Write-Debug "[Get-JiraIssue] Issue key is assumed to be [$issueKey] via ToString()" } Write-Debug "[Get-JiraIssue] Invoking myself with the Key parameter set to search for issue [$issueKey]" $issueObj = Get-JiraIssue -Key $issueKey -Credential $Credential Write-Debug "[Get-JiraIssue] Returned from invoking myself; outputting results" Write-Output $issueObj } } elseif ($PSCmdlet.ParameterSetName -eq 'ByJQL') { Write-Debug "[Get-JiraMethod] Escaping query and building URL" $escapedQuery = [System.Web.HttpUtility]::UrlPathEncode($Query) $issueURL = "$($server)/rest/api/latest/search?jql=$escapedQuery&validateQuery=true&expand=transitions&maxResults=$MaxResults" Write-Debug "[Get-JiraMethod] Preparing for blastoff!" $result = Invoke-JiraMethod -Method Get -URI $issueURL -Credential $Credential if ($result) { # {"startAt":0,"maxResults":50,"total":0,"issues":[]} if ($result.total -gt 0) { Write-Debug "[Get-JiraMethod] Converting REST result to Jira issue" $obj = ConvertTo-JiraIssue -InputObject $result.issues Write-Debug "[Get-JiraMethod] Outputting result" Write-Output $obj } else { Write-Debug "[Get-JiraMethod] No results were found for the specified query" Write-Verbose "No results were found for the query [$Query]" } } else { Write-Debug "[Get-JiraMethod] Invoke-JiraMethod returned no results" } } elseif ($PSCmdlet.ParameterSetName -eq 'ByFilter') { $filterObj = Get-JiraFilter -InputObject $Filter -Credential $Credential if ($filterObj) { $jql = $filterObj.JQL Write-Debug "[Get-JiraIssue] Invoking myself with filter JQL: [$jql]" $result = Get-JiraIssue -Query $jql -Credential $Credential -MaxResults $MaxResults if ($result) { Write-Debug "[Get-JiraIssue] Returned from invoking myself; outputting results" Write-Output $result } else { Write-Debug "[Get-JiraIssue] Returned from invoking myself, but no results were found" } } else { Write-Debug "[Get-JiraIssue] Unable to identify filter [$Filter]" Write-Error "Unable to identify filter [$Filter].
