I'm trying to update an already-existing page in Confluence using PowerShell's Invoke-WebRequest cmdlet. I've used this method many times in both getting and putting information into a series of different REST APIs including JIRA, and my GET requests work with Confluence too. So I know my usage of Invoke-WebRequest is correct, but have to assume there's something wrong with the "body" of my request.
Here's my code:
-------------------------------------------------------------------------------
$Credentials = Get-Credential
$MaxJsonLength = 67108864
$ConfluenceURL = "https://confluenceurl/rest/api/"
$ConfluencePageID = "123456789"
$Headers = @{"Authorization" = "Basic "+[System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes(($Credentials.UserName+":"+[System.Runtime.InteropServices.marshal]::PtrToStringAuto([System.Runtime.InteropServices.marshal]::SecureStringToBSTR($Credentials.Password)) )))}
$Call = "content/$($ConfluencePageID)?expand=body.storage,version,space,ancestors"
$CurrentConfluence = Invoke-WebRequest -Method GET -Headers $Headers -Uri ($ConfluenceURL + $Call)
$JSONSerial = New-Object -TypeName System.Web.Script.Serialization.JavaScriptSerializer
$JSONSerial.MaxJsonLength = $MaxJsonLength
$CurrentConfluence = ($JSONSerial.DeserializeObject($CurrentConfluence))
$Body = @{
"id" = ($CurrentConfluence.id)
"type" = "page"
"title" = ($CurrentConfluence.title)
"version" = @{
"number" = ($CurrentConfluence.version.number + 1)
}
"status" = "current"
"space" = @{
"id" = ($CurrentConfluence.space.id)
"key" = ($CurrentConfluence.space.key)
"name" = ($CurrentConfluence.space.name)
"type" = ($CurrentConfluence.space.type)
}
"ancestors" = @{
"id" = ($CurrentConfluence.ancestors.id)
"type" = ($CurrentConfluence.ancestors.type)
"status" = ($CurrentConfluence.ancestors.status)
"title" = ($CurrentConfluence.ancestors.title)
}
"body" = @{
"storage" = @{
"value" = "This is a newly-posted Confluence page"
"representation" = "editor"
}
}
}
$Body = $Body | ConvertTo-Json
$ContentType = "application/json"
$Call = "content/$($ConfluencePageID)"
$UpdateConfluence = Invoke-WebRequest -Method PUT -Uri ($ConfluenceURL + $Call) -Body $Body -ContentType $ContentType
$JSONSerial = New-Object -TypeName System.Web.Script.Serialization.JavaScriptSerializer
$JSONSerial.MaxJsonLength = $MaxJsonLength
$UpdateConfluence = ($JSONSerial.DeserializeObject($UpdateConfluence))
-------------------------------------------------------------------------------
The first REST GET call I make with at the top works fine ($CurrentConfluence), but I keep getting 400 Bad Request errors on my "$UpdateConfluence" line where attempt a PUT call.
I've played with the body section of my code as many ways as I can but can't seem to find the proper combination. Version aside (documented here: https://docs.atlassian.com/confluence/REST/latest-server/#content-update) are there any other requirements needed to perform an update? Really the ONLY thing I want to update is the body.storage.value field. I want to keep everything else the same. I have the other body code in my example because other posts on the web seem to include it.
ancestors expects an array of objects, so in order for this to work you would have to it like this:
"ancestors" = @(
@{"id" = '27820213'}
)
Could it be that your are sending ancestors field as an object rather than an array ?
