# <copyright file="Invoke-AzCliRestCommand.ps1" company="Endjin Limited"> # Copyright (c) Endjin Limited. All rights reserved. # </copyright> <# .SYNOPSIS Provides a wrapper around the 'az rest' command included with the azure-cli. .DESCRIPTION Provides a wrapper around the 'az rest' command included with the azure-cli, handling all the necessary JSON escaping. .PARAMETER Uri The Uri of the request to be invoked. .PARAMETER Method The REST method of the request to be invoked. .PARAMETER Body The body of the request to be invoked, represented as a hashtable or an array of hashtables. .PARAMETER BodyFilePath The path to the file containing the body of the request to be invoked. .PARAMETER Headers The HTTP headers required by the request to be invoked. The "Content-Type" header will be automatically added if missing: @{ "Content-Type" = "application/json" } .PARAMETER ResourceForAuth Resource url for which CLI should acquire a token from AAD in order to access the service. The token will be placed in the Authorization header. By default, CLI can figure this out based on --url argument, unless you use ones not in the list of "az cloud show --query endpoints" .OUTPUTS The JSON output from the underlying azure-cli command, in hashtable format. #> function Invoke-AzCliRestCommand { [CmdletBinding(DefaultParameterSetName = 'Body as hashtable')] param ( [Parameter(Mandatory = $true, ParameterSetName = 'Body as hashtable')] [Parameter(Mandatory = $true, ParameterSetName = 'Body as file')] [string] $Uri, [Parameter(ParameterSetName = 'Body as hashtable')] [Parameter(ParameterSetName = 'Body as file')] [ValidateSet("DELETE", "GET", "PATCH", "POST", "PUT")] [string] $Method = "GET", [Parameter(ParameterSetName = 'Body as hashtable')] $Body, [Parameter(Mandatory = $true, ParameterSetName = 'Body as file')] [string] $BodyFilePath, [Parameter(ParameterSetName = 'Body as hashtable')] [Parameter(ParameterSetName = 'Body as file')] [hashtable] $Headers = @{}, [Parameter(ParameterSetName = 'Body as hashtable')] [Parameter(ParameterSetName = 'Body as file')] [string] $ResourceForAuth ) # Ensure we always have the 'Content-Type' header if ( !$Headers.ContainsKey("Content-Type") ) { $Headers += @{ "Content-Type" = "application/json" } } # perform any query string escaping $uriEscaped = $Uri.Replace("'", "''") # start building up the 'az rest' command-line $cmdParts = @( "rest" "--uri '$uriEscaped'" "--method $Method" ) if ($ResourceForAuth) { $cmdParts += "--resource $ResourceForAuth" } # Additional arguments for methods with body semantics if (@("PUT", "POST", "PATCH") -contains $Method) { switch ($PSCmdlet.ParameterSetName) { "Body as hashtable" { if ($Body -is [hashtable] -or ($Body -is [array] -and $Body[0] -is [hashtable])) { $bodyAsJson = (ConvertTo-Json $Body -Depth 100 -Compress).replace('"', '\"').replace(':\', ': \').replace("'", "''") } else { throw "The -Body parameter must be of type [hashtable] or [hashtable[]]" } break } "Body as file" { $bodyAsJson = "@$BodyFilePath" break } } $headersAsEscapedJsonString = (ConvertTo-Json $Headers -Compress).replace('"', '\"').replace(':\', ': \').replace("'", "''") $cmdParts += "--body '$bodyAsJson'" $cmdParts += "--headers '$headersAsEscapedJsonString'" } $response = Invoke-AzCli -Command ($cmdParts -join " ") -AsJson return $response } |
