Function Test-AHFunctionApp { <# .SYNOPSIS This function runs all the functions in a function app. .DESCRIPTION This function runs all the functions in a function app. This is useful for testing functions that are not HTTP triggered. .PARAMETER SubscriptionId The subscription ID of the function app .PARAMETER TenantId The tenant ID of the function app .PARAMETER ResourceGroupName The resource group name of the function app .PARAMETER FunctionAppName The name of the function app .PARAMETER waitPeriod The number of seconds to wait between running each function. The default is 30 seconds. .EXAMPLE Test-AHFunctionApp -SubscriptionId '00000000-0000-0000-0000-000000000000' -ResourceGroupName 'functions-test' -FunctionAppName 'aztosoTest' Runs all the functions in the function app 'aztosoTest' in the resource group 'functions-test' in the subscription '00000000-0000-0000-0000-000000000000' .INPUTS String .OUTPUTS None #> param( [Parameter(Mandatory = $false)] [string]$SubscriptionId = (Get-AzContext).Subscription.Id, [Parameter(Mandatory = $false)] [string]$TenantId = (Get-AzContext).Tenant.Id, [Parameter(Mandatory = $true)] [string]$ResourceGroupName, [Parameter(Mandatory = $true)] [string]$FunctionAppName, [Parameter(Mandatory = $false)] [int]$waitPeriod = 30 ) begin { Set-AzContext -SubscriptionId $SubscriptionId -TenantId $TenantId | Out-Null $environment = (Get-AzContext).Environment.Name $resourceManagerUrl = (Get-AzEnvironment -Name $(Get-AzContext).environment.name).ResourceManagerUrl $ADAuthorityURI = (Get-AzEnvironment -Name $(Get-AzContext).environment.name).ActiveDirectoryAuthority } process { #This is in the process block in case different functions are passed to this function in through the pipeline Switch ($environment) { 'AzureUsGovernment' { $functionAppUrl = "https://$FunctionAppName.azurewebsites.us/" } 'AzureCloud' { $functionAppUrl = "https://$FunctionAppName.azurewebsites.net/" } 'AzureChinaCloud' { $functionAppUrl = "https://$FunctionAppName.azurewebsites.chinacloudapi.cn/" } 'AzureGermanCloud' { $functionAppUrl = "https://$FunctionAppName.azurewebsites.cloudapi.de/" } } $resourceManagerToken = (Get-AzAccessToken -ResourceUrl $resourceManagerUrl).Token # get the master host key # - https://learn.microsoft.com/en-us/rest/api/appservice/web-apps/list-host-keys # - https://aztoso.com/functions/keys/#:~:text=To%20get%20the%20host%2C%20master%2C%20and%20system%20key%2C,following%20command%3A%20az%20functionapp%20keys%20list%20-grg-functions-test%20-naztosotest $uri = $resourceManagerUrl + "/subscriptions/$SubscriptionId/resourceGroups/$ResourceGroupName/providers/Microsoft.Web/sites/$FunctionAppName/host/default/listkeys?api-version=2018-11-01" $header = @{Authorization = "Bearer $resourceManagerToken" } $result = Invoke-RestMethod -Method Post -Uri $uri -Headers $header $MasterKey = $result.masterKey $FunctionApp = Get-AzFunctionApp -ResourceGroupName $ResourceGroupName -Name $FunctionAppName #Find all the functions in the function app # - https://learn.microsoft.com/en-us/rest/api/appservice/web-apps/list-functions $uri = $resourceManagerUrl + "/subscriptions/$SubscriptionId/resourceGroups/$ResourceGroupName/providers/Microsoft.Web/sites/$FunctionAppName/functions?api-version=2018-11-01" $functions = Invoke-RestMethod -Method Get -Uri $uri -Headers $header # Run the functions # - https://learn.microsoft.com/en-us/azure/azure-functions/functions-manually-run-non-http ForEach ($function in $functions.value) { $uri = $functionAppUrl + "admin/functions/$($function.properties.Name)" $header = @{ 'x-functions-key' = $MasterKey 'Content-Type' = 'application/json' } $body = @{ input = 'test' } $result = Invoke-RestMethod -Method Post -Uri $uri -Headers $header -Body ($body | ConvertTo-Json) Start-Sleep -Seconds $waitPeriod } } end { } } |
