<# .SYNOPSIS Ability to execute REST API calls which don't exist in a dedicated function yet .DESCRIPTION Ability to execute REST API calls which don't exist in a dedicated function yet .PARAMETER VenafiSession VenafiSession object from New-VenafiSession. For typical calls to New-VenafiSession, the object will be stored as a session object named $VenafiSession. Otherwise, if -PassThru was used, provide the resulting object. .PARAMETER Method API method, either get, post, patch, put or delete. .PARAMETER UriLeaf Path to the api endpoint excluding the base url and site, eg. certificates/import .PARAMETER Header Optional additional headers. The authorization header will be included automatically. .PARAMETER Body Optional body to pass to the endpoint .INPUTS None .OUTPUTS PSCustomObject .EXAMPLE Invoke-VenafiRestMethod -Method Delete -UriLeaf 'Discovery/{1345311e-83c5-4945-9b4b-1da0a17c45c6}' Api call .EXAMPLE Invoke-VenafiRestMethod -Method Post -UriLeaf 'Certificates/Revoke' -Body @{'CertificateDN'='\ved\policy\mycert.com'} Api call with optional payload #> function Invoke-VenafiRestMethod { [CmdletBinding(DefaultParameterSetName = 'Session')] param ( [Parameter(ParameterSetName = 'Session')] [ValidateNotNullOrEmpty()] [VenafiSession] $VenafiSession = $script:VenafiSession, [Parameter(Mandatory, ParameterSetName = 'URL')] [ValidateNotNullOrEmpty()] [Alias('ServerUrl')] [String] $Server, [Parameter(ParameterSetName = 'URL')] [Alias('UseDefaultCredentials')] [switch] $UseDefaultCredential, [Parameter(ParameterSetName = 'URL')] [X509Certificate] $Certificate, [Parameter()] [ValidateSet("Get", "Post", "Patch", "Put", "Delete", 'Head')] [String] $Method = 'Get', [Parameter()] [String] $UriRoot = 'vedsdk', [Parameter(Mandatory)] [ValidateNotNullOrEmpty()] [String] $UriLeaf, [Parameter()] [hashtable] $Header, [Parameter()] [Hashtable] $Body, [Parameter()] [switch] $FullResponse ) if ( $PSCmdLet.ParameterSetName -eq 'Session' ) { $Server = $VenafiSession.Server if ( $VenafiSession.Platform -eq 'VaaS' ) { $hdr = @{ "tppl-api-key" = $VenafiSession.Key.GetNetworkCredential().password } if ( -not $PSBoundParameters.ContainsKey('UriRoot') ) { $UriRoot = 'v1' } } else { # TPP if ( $VenafiSession.AuthType -eq 'Token' ) { $hdr = @{ 'Authorization' = 'Bearer {0}' -f $VenafiSession.Token.AccessToken.GetNetworkCredential().password } } else { # key based tpp $hdr = @{ "X-Venafi-Api-Key" = $VenafiSession.Key.ApiKey } } } } $uri = '{0}/{1}/{2}' -f $Server, $UriRoot, $UriLeaf if ( $Header ) { $hdr += $Header } $params = @{ Method = $Method Uri = $uri Headers = $hdr ContentType = 'application/json' UseBasicParsing = $true } if ( $Body ) { $restBody = $Body switch ($Method.ToLower()) { 'head' { # a head method requires the params be provided as a query string, not body # invoke-webrequest does not do this so we have to build the string manually $newUri = New-HttpQueryString -Uri $uri -QueryParameter $Body $params.Uri = $newUri $params.Body = $null Write-Verbose $newUri } 'get' { $params.Body = $restBody } Default { $restBody = ConvertTo-Json $Body -Depth 20 $params.Body = $restBody } } } if ( $UseDefaultCredential.IsPresent -and $Certificate ) { throw 'You cannot use UseDefaultCredential and Certificate parameters together' } if ( $UseDefaultCredential.IsPresent ) { $params.Add('UseDefaultCredentials', $true) } $params | Write-VerboseWithSecret # ConvertTo-Json, used in Write-VerboseWithSecret, has an issue with certificates # add this param after if ( $Certificate ) { $params.Add('Certificate', $Certificate) } $oldProgressPreference = $ProgressPreference $ProgressPreference = 'SilentlyContinue' try { $verboseOutput = $($response = Invoke-WebRequest @params -ErrorAction Stop) 4>&1 $verboseOutput.Message | Write-VerboseWithSecret } catch { # if trying with a slash below doesn't work, we want to provide the original error $originalError = $_ $originalStatusCode = $originalError.Exception.Response.StatusCode.value__ Write-Verbose ('Response status code {0}' -f $originalStatusCode) switch ($originalStatusCode) { '409' { # item already exists. some functions use this for a 'force' option, eg.
