Enter a variable that contains the string, or type a command or expression that gets the string. You can also pipe a string to ConvertFrom-Json. .PARAMETER MaxJsonLength Specifies the MaxJsonLength, can be used to extend the size of strings that are converted. This is the main feature of this cmdlet vs the native ConvertFrom-Json2 .EXAMPLE Get-Date | Select-Object -Property * | ConvertTo-Json | ConvertFrom-Json DisplayHint : 2 DateTime : Friday, January 13, 2012 8:06:31 PM Date : 1/13/2012 8:00:00 AM Day : 13 DayOfWeek : 5 DayOfYear : 13 Hour : 20 Kind : 2 Millisecond : 400 Minute : 6 Month : 1 Second : 31 Ticks : 634620819914009002 TimeOfDay : @{Ticks=723914009002; Days=0; Hours=20; Milliseconds=400; Minutes=6; Seconds=31; TotalDays=0.83786343634490734; TotalHours=20.108722472277776; TotalMilliseconds=72391400.900200009; TotalMinutes=1206.5233483366667;TotalSeconds=72391.4009002} Year : 2012 This command uses the ConvertTo-Json and ConvertFrom-Json cmdlets to convert a DateTime object from the Get-Date cmdlet to a JSON object. The command uses the Select-Object cmdlet to get all of the properties of the DateTime object. It uses the ConvertTo-Json cmdlet to convert the DateTime object to a JSON-formatted string and the ConvertFrom-Json cmdlet to convert the JSON-formatted string to a JSON object.. .EXAMPLE PS C:\>$j = Invoke-WebRequest -Uri http://search.twitter.com/search.json?q=PowerShell | ConvertFrom-Json This command uses the Invoke-WebRequest cmdlet to get JSON strings from a web service and then it uses the ConvertFrom-Json cmdlet to convert JSON content to objects that can be managed in Windows PowerShell. You can also use the Invoke-RestMethod cmdlet, which automatically converts JSON content to objects. Example 3 PS C:\>(Get-Content JsonFile.JSON) -join "`n" | ConvertFrom-Json This example shows how to use the ConvertFrom-Json cmdlet to convert a JSON file to a Windows PowerShell custom object. The command uses Get-Content cmdlet to get the strings in a JSON file. It uses the Join operator to join the strings in the file into a single string that is delimited by newline characters (`n). Then it uses the pipeline operator to send the delimited string to the ConvertFrom-Json cmdlet, which converts it to a custom object. The Join operator is required, because the ConvertFrom-Json cmdlet expects a single string. .NOTES Author: Reddit Version History: 1.0 - Initial release Known Issues: 1.0 - Does not convert nested objects to psobjects .LINK #> [CmdletBinding(SupportsShouldProcess=$true,ConfirmImpact='Low')] param ( [parameter( ParameterSetName='object', ValueFromPipeline=$true, Mandatory=$true)] [string] $InputObject, [parameter( ParameterSetName='object', ValueFromPipeline=$true, Mandatory=$false)] [int] $MaxJsonLength = 67108864 )#end param BEGIN { #Configure json deserializer to handle larger then average json conversion [void][System.Reflection.Assembly]::LoadWithPartialName('System.Web.Extensions') $jsonserial= New-Object -TypeName System.Web.Script.Serialization.JavaScriptSerializer $jsonserial.MaxJsonLength = $MaxJsonLength } #End BEGIN PROCESS { if ($PSCmdlet.ParameterSetName -eq 'object') { $deserializedJson = $jsonserial.DeserializeObject($InputObject) # Convert resulting dictionary objects to psobjects foreach($desJsonObj in $deserializedJson){ $psObject = New-Object -TypeName psobject -Property $desJsonObj $dicMembers = $psObject | Get-Member -MemberType NoteProperty foreach ($member in $dicMembers){ $member.GetType() if ($member -is [System.Collections.Generic.Dictionary`2]) { $psObject.$member = New-Object -TypeName psobject -Property $psObject.$member $a = 0; } $x = 0; } # Need to recursively go through members of the originating psobject that have a .GetType() Name of 'Dictionary`2' # and convert to psobjects and replace the current member in the $psObject tree $psObject } } }#end PROCESS END { }#end END } if ([String]::IsNullOrEmpty($repositoryID)){ Write-Log "Please pass a repositoryID" Error -ErrorAction Stop } $BaseTFSURL = Get-TFSRestURL_Collection $action = "/wit/workitems/$($workItemID)?api-version=$($script:apiVersion)" $fullURL = $BaseTFSURL + $action Write-Log "URL we are calling: $fullURL" Debug $outputObj = $pipelineInput try{ $response = Invoke-RestMethod -UseDefaultCredentials -uri $fullURL -Method Get -ContentType "application/json" $json = $response $x = 0; } catch{ $ex = $_.Exception if ($ex.response -ne $null){ $errResponse = $ex.Response.GetResponseStream() $reader = New-Object System.IO.StreamReader($errResponse) $reader.BaseStream.Position = 0 $reader.DiscardBufferedData() $responseBody = $reader.ReadToEnd(); $responseBody } $line = $_.InvocationInfo.ScriptLineNumber $scriptName = Split-Path $_.InvocationInfo.ScriptName -Leaf $msg = $ex.Message Write-Log "Error in script $scriptName at line $line, error message: $msg" Warning } if([bool]($outputObj.PSobject.Properties.name -match "WorkItems")){ $outputObj.WorkItems += $json } else{ $outputObj | Add-Member -Type NoteProperty -Name WorkItems -Value $json } Write-Output $outputObj }Export-ModuleMember -Function Get-TFSWorkItem |
