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 #> function Invoke-VenafiRestMethod { [CmdletBinding(DefaultParameterSetName = 'Session')] param ( [Parameter(Mandatory, ParameterSetName = 'Session')] [ValidateNotNullOrEmpty()] [VenafiSession] $VenafiSession, [Parameter(Mandatory, ParameterSetName = 'URL')] [ValidateNotNullOrEmpty()] [String] $ServerUrl, [Parameter(ParameterSetName = 'URL')] [switch] $UseDefaultCredentials, [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] $FullResponse ) switch ($PSCmdLet.ParameterSetName) { 'Session' { $ServerUrl = $VenafiSession.ServerUrl switch ($VenafiSession | Get-VenafiAuthType) { 'key' { $hdr = @{ "X-Venafi-Api-Key" = $VenafiSession.Key.ApiKey } } 'token' { $hdr = @{ 'Authorization' = 'Bearer {0}' -f $VenafiSession.Token.AccessToken.GetNetworkCredential().password } } 'vaas' { $hdr = @{ "tppl-api-key" = $VenafiSession.Key.GetNetworkCredential().password } } Default {} } $uri = '{0}/{1}/{2}' -f $ServerUrl, $UriRoot, $UriLeaf } 'URL' { $uri = '{0}/{1}/{2}' -f $ServerUrl, $UriRoot, $UriLeaf } Default {} } 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 ( $UseDefaultCredentials ) { $params.Add('UseDefaultCredentials', $true) } $params | Write-VerboseWithSecret $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.
