- 21. 21 Let’s dig into the code
- 22. Cmdlets for Calling a RESTful API • Invoke-WebRequest – Returns the entire response – Status, headers, body content, etc. • Invoke-RestMethod – Returns only the content from the response 22
- 23. Endpoints / Resources • The available actions, expressed as URIs – Uniform Resource Identifier – Example: https://the.device.url/system/version • Should be published somewhere – If not, harass the vendor 23
- 24. 24
- 25. Methods • Actions towards an endpoint / resource – GET – PUT – POST – DELETE – PATCH – Etc. 25
- 26. Authentication • Verify your identity – Basic auth – Oauth(quite common) – Oauth2 • Often placed in the header – Basic auth uses Base64 encoding + SSL – SSL is “optional” – but don’t call endpoints with HTTP! 26
- 27. Sample Basic Auth Code for PowerShell $auth = [System.Convert]::ToBase64String([System.Text.Encoding]: :UTF8.GetBytes($Username + “:” + $Password)) $header = @{“Authorization”=“Basic $auth”} 27
