Overview of this book

PowerShell scripts offer a handy way to automate various chores. Working with these scripts effectively can be a difficult task. This comprehensive guide starts from scratch and covers advanced-level topics to make you a PowerShell expert. The first module, PowerShell Fundamentals, begins with new features, installing PowerShell on Linux, working with parameters and objects, and also how you can work with .NET classes from within PowerShell. In the next module, you’ll see how to efficiently manage large amounts of data and interact with other services using PowerShell. You’ll be able to make the most of PowerShell’s powerful automation feature, where you will have different methods to parse and manipulate data, regular expressions, and WMI. After automation, you will enter the Extending PowerShell module, which covers topics such as asynchronous processing and, creating modules. The final step is to secure your PowerShell, so you will land in the last module, Securing and Debugging PowerShell, which covers PowerShell execution policies, error handling techniques, and testing.

Preface

Working with REST


A REpresentational State Transfer (REST), it compliant web service allows a client to interact with the service using a set of predefined stateless operations. REST is not a protocol, it is an architectural style.

Whether or not an interface is truly REST-compliant is not particularly relevant when the goal is to use one in PowerShell. Interfaces must be used according to any documentation that has been published.

Invoke-RestMethod

The Invoke-RestMethod command is able to execute methods exposed by web services. The name of a method is part of the Uniform Resource Identifier (URI), it is important not to confuse this with the Method parameter. The Method parameter is used to describe the HTTP method. By default, Invoke-RestMethod uses the HTTPGET.

Simple requests

The REST API provided by GitHub may be used to list the repositories made available by the PowerShell team.

The API entry point is https://api.github.com as documented in the reference:
