Function Connect-SKYAPI { <# .LINK https://github.com/Sekers/SKYAPI/wiki .LINK Endpoint: https://developer.sky.blackbaud.com/docs/services/school/operations/V1AcademicsTeachersByTeacher_idSectionsGet .SYNOPSIS Education Management School API - Verify cached tokens exist and are not expired using Connect-SKYAPI. Connect-SKYAPI will automatically refresh tokens or reauthenticate to the SKY API service, if necessary. .DESCRIPTION Education Management School API - Verify cached tokens exist and are not expired using Connect-SKYAPI. Connect-SKYAPI will automatically refresh tokens or reauthenticate to the SKY API service, if necessary. .PARAMETER ForceReauthentication Forces reauthentication. .PARAMETER ForceRefresh Forces token refresh. .PARAMETER ClearBrowserControlCache Used in conjunction with 'ForceReauthentication'. Clears the Microsoft Edge WebView2 or Internet Explorer control browser cache. Useful when troubleshooting authentication. .PARAMETER AuthenticationMethod Let's you specify how you want to authenticate if authentication is necessary: - EdgeWebView2 (default): Opens a web browser window using Microsoft Edge WebView2 for authentication. Requires the WebView2 Runtime to be installed. If not installed, will prompt for automatic installation. - LegacyIEControl: Opens a web browser window using the old Internet Explorer control. This is no longer supported by Blackbaud. - MiniHTTPServer: Alternate method of capturing the authentication using your user account's default web browser and listening for the authentication response using a temporary HTTP server hosted by the module. .PARAMETER ReturnConnectionInfo Returns connection information after performing function. .EXAMPLE Connect-SKYAPI .EXAMPLE Connect-SKYAPI -ForceReauthentication .EXAMPLE Connect-SKYAPI -ForceReauthentication -ClearBrowserControlCache .EXAMPLE Connect-SKYAPI -ForceReauthentication -AuthenticationMethod MiniHTTPServer .EXAMPLE Connect-SKYAPI -ForceRefresh .EXAMPLE Connect-SKYAPI -ReturnConnectionInfo #> [CmdletBinding(DefaultParameterSetName='NoParameters')] Param( [parameter( Position=0, ParameterSetName = 'ForceReauthentication', ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)] [Switch]$ForceReauthentication, [parameter( Position=1, ParameterSetName = 'ForceRefresh', ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)] [Switch]$ForceRefresh, [parameter( Position=2, Mandatory=$false, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)] [ValidateSet('EdgeWebView2','MiniHTTPServer',"LegacyIEControl")] [string]$AuthenticationMethod, [parameter( Position=3, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)] [Switch]$ReturnConnectionInfo ) DynamicParam { # Initialize Parameter Dictionary $ParameterDictionary = [System.Management.Automation.RuntimeDefinedParameterDictionary]::new() # Make -ClearBrowserControlCache Parameter Only Appear if ForceReauthentication is Used # DynamicParameter1: ClearBrowserControlCache if ($ForceReauthentication) { $ParameterAttributes = [System.Management.Automation.ParameterAttribute]@{ ParameterSetName = "ForceReauthentication" Mandatory = $false ValueFromPipeline = $true ValueFromPipelineByPropertyName = $true } $AttributeCollection = [System.Collections.ObjectModel.Collection[System.Attribute]]::new() $AttributeCollection.Add($ParameterAttributes) $DynamicParameter1 = [System.Management.Automation.RuntimeDefinedParameter]::new( 'ClearBrowserControlCache', [switch], $AttributeCollection) $ParameterDictionary.Add('ClearBrowserControlCache', $DynamicParameter1) } return $ParameterDictionary } begin { $ClearBrowserControlCache = $PSBoundParameters['ClearBrowserControlCache'] } process { # Set the Necesasary Configuration Variables $sky_api_config = Get-SKYAPIConfig -ConfigPath $sky_api_config_file_path $client_id = $sky_api_config.client_id $client_secret = $sky_api_config.client_secret $redirect_uri = $sky_api_config.redirect_uri $token_uri = $sky_api_config.token_uri # If Key File Does Not Exist or the -ForceReauthentication Parameter is Set, Ask User to Reauthenticate if ((-not (Test-Path $sky_api_tokens_file_path)) -or ($ForceReauthentication)) { Get-SKYAPINewTokens -sky_api_tokens_file_path $sky_api_tokens_file_path -AuthenticationMethod $AuthenticationMethod -ClearBrowserControlCache:$ClearBrowserControlCache } # Get Tokens & Set Creation Times try { $AuthTokensFromFile = Get-SKYAPIAuthTokensFromFile $refresh_token_creation = $AuthTokensFromFile.refresh_token_creation $access_token_creation = $AuthTokensFromFile.access_token_creation } catch { throw "Key JSON tokens file is corrupted or invalid.
