This is the second post in a series of posts about how to use PowerShell and JSON to build REST APIs. Today, we’ll look at four more demos on using these technologies with web services.

The “powershell extract data from json file” is a PowerShell command that can be used to extract data from a JSON file. Here are four demos of the command in action!

Wrangling REST APIs with PowerShell and JSON (Four Demos!)

The first step you’ll need to complete is to call. This HTTP endpoint is a URI that your client (PowerShell in this case) will query.

  1. Go to File —> New File to create a blank text document.

is very similar to using Invoke-WebRequest. It really only eliminates a single line of code, as the cmdlet will automatically assume a JSON response and convert it for you. It is, however, better for clarity. It makes it clear in the code that you are expecting to be using an API and you are also expecting a JSON response. Clearer code is always a good thing!

## WindowsSettings.ps1 param ( [Parameter(ParameterSetName = ‘cmd’, Mandatory = $true)] [String]$ComputerName, [Parameter(ParameterSetName = ‘cmd’)] [String]$Timezone, [Parameter(ParameterSetName = ‘cmd’)] [Switch]$Install7zip, [Parameter(ParameterSetName = ‘cmd’)] [Switch]$InstallVSCode, [Parameter(ParameterSetName = ‘cmd’)] [Switch]$InstallGoogleChrome, [Parameter(ParameterSetName = ‘json’)] [String]$JSON ) if($JSON) { ## *the ashashtable parameter for ConvertFrom-json was added in ## Powershell 7. If you are following along with Powershell 5.1, ## this will not work (or you will have to find a way to convert the ## PSObject to a Hashtable).* $config = ConvertFrom-Json $json -ashashtable &$MyInvocation.MyCommand @config exit } write-output $computername, $timezone

## WindowsSettings.ps1 param ( [Parameter(ParameterSetName = ‘cmd’, Mandatory = $true)] [String]$ComputerName, [Parameter(ParameterSetName = ‘cmd’, Mandatory = $true)] [String]$Timezone, [Parameter(ParameterSetName = ‘cmd’)] [Switch]$Install7zip, [Parameter(ParameterSetName = ‘cmd’)] [Switch]$InstallVSCode, [Parameter(ParameterSetName = ‘cmd’)] [Switch]$InstallGoogleChrome, [Parameter(ParameterSetName = ‘cmd’)] [string]$ExportConfig, [Parameter(ParameterSetName = ‘json’)] [String]$JSON ) if($JSON) { $config = ConvertFrom-Json $json -ashashtable &$MyInvocation.MyCommand @config exit } if ($ExportConfig) { write-output “exporting config to $($exportConfig)” ## Grab all of the parameters provided into a $params object. $params = $PSBoundParameters #convert all switches to booleans. We do this because passing switches as JSON doesn’t behave as expected $keys = $params.keys.clone() foreach ($key in $keys) { if ($params[$key]) { ## Switches don’t work that well in a JSON format, so you loop ## through the $params object and convert any existing switches to ## Booleans if ($params[$key].gettype().name -eq “SwitchParameter”) { $params[$key] = $params[$key].IsPresent } } } #export to a file ## Export it to the location provided in $exportConfig $params | convertto-JSON | out-file $exportConfig } write-output $computername, $timezone

The “powershell rest api endpoint” is a PowerShell command that allows users to create REST APIs. The demos will show how to use the tool and also include some useful tips on wrangling REST APIs.

Frequently Asked Questions

Can you use PowerShell for REST API?

A: PowerShell is not the best tool for making REST API.

How do I run a REST API in PowerShell?

What is JSON and REST API?

A: JSON stands for JavaScript Object Notation and is a standard text-based open format that you can use to store structured data in a file or transmit it over the internet.
