(Visual FoxPro) 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

* 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.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.OAuth1')
loOauth1 = CreateObject('Chilkat.OAuth1')
loOauth1.ConsumerKey = "WOO_COMMERCE_CONSUMER_KEY"
loOauth1.ConsumerSecret = "WOO_COMMERCE_CONSUMER_SECRET"

* The signature method can be HMAC-SHA1 or HMAC-SHA256
loOauth1.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..
loOauth1.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"
lnSuccess = loOauth1.AddParam("status","processing")

* The OAuthMethod property will be set automatically when the REST request is sent.
* Setting it here is not actually necessary.
loOauth1.OauthMethod = "GET"

* Generate an initial nonce so that Chilkat knows the desired size of the nonce.
lnSuccess = loOauth1.GenNonce(32)

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Rest')
loRest = CreateObject('Chilkat.Rest')

* Tell the REST object to use the OAuth1 object for authentication.
* Also, indicate that the OAuth authentication parameters should be query parameters
* and not located within the Authorization header.
lnBUseQueryParams = 1
lnSuccess = loRest.SetAuthOAuth1(loOauth1,lnBUseQueryParams)

* Make the initial connection (without sending a request yet) to the WooCommerce endpoint at your Wordpress blog.
lnBTls = 0
lnPort = 80
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("your-wordpress-site.com",lnPort,lnBTls,lnBAutoReconnect)
IF (lnSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loOauth1
    RELEASE loRest
    CANCEL
ENDIF

* Send a GET request to list orders.

* The extra query params must be added here.
* (Whatever params are added here should've also been added to the OAuth1 object.)
lnSuccess = loRest.AddQueryParam("status","processing")

* When the request is sent, the OAuth1 object's Timestamp and Nonce properties are automatically
* regenerated.  Also, the OAuth1 object's OauthMethod property is automatically set to the HTTP method
* used for the request (in this case it is "GET").
lcResponseJson = loRest.FullRequestNoBody("GET","/wc-api/v3/orders")
IF (loRest.LastMethodSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loOauth1
    RELEASE loRest
    CANCEL
ENDIF

* When successful, the response status code will equal 200.
IF (loRest.ResponseStatusCode <> 200) THEN
    * Examine the request/response to see what happened.
