REST OAuth1 with Params

Demonstrates how to use OAuth 1.0a "one legged" authentication with Woo Commerce, with URLs that use query parameters. For example: /orders?status=processing Visual Basic 6.0

' Demonstrates how to do OAuth1 authentication with query parameters (for a Wordpress site using Woo Commerce).

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' Prepare an OAuth 1.0 object for use with the Chilkat REST API.

oauth1.SignatureMethod = "HMAC-SHA256"

' The OauthUrl property will need to be updated each time a request is sent.
' The domain here must match the domain passed to the Connect method (below).
' The domain must be exact.  For example, "www.your-wordpress-site.com" vs. "your-wordpress-site.com".
' One might work while the other does not..
oauth1.OauthUrl = "http://your-wordpress-site.com/wc-api/v3/orders"

' We need to tell OAuth1 about our extra query parameters so they can be used
' in generating the OAuth1 signature.
' In this example, we want to add the param "status=processing"
success = oauth1.AddParam("status","processing")

' The OAuthMethod property will be set automatically when the REST request is sent.
' Setting it here is not actually necessary.
oauth1.OauthMethod = "GET"

' Generate an initial nonce so that Chilkat knows the desired size of the nonce.
success = oauth1.GenNonce(32)

' Also, indicate that the OAuth authentication parameters should be query parameters
' and not located within the Authorization header.

' (Whatever params are added here should've also been added to the OAuth1 object.)
