    // Demonstrates how to do OAuth1 authentication 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.
    let oauth1 = CkoOAuth1()!

    // The signature method can be HMAC-SHA1 or HMAC-SHA256
    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"

    // 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.
    var success: Bool = oauth1.genNonce(32)

    let rest = CkoRest()!

    // 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.
    var bUseQueryParams: Bool = true
    success = rest.setAuthOAuth1(oauth1, useQueryParams: bUseQueryParams)

    // Make the initial connection (without sending a request yet) to the WooCommerce endpoint at your Wordpress blog.

    if success != true {
        print("\(rest.lastErrorText!)")
        return
    }

    // Send a GET request to list orders.

    // 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").
    var responseJson: String? = rest.fullRequestNoBody("GET", uriPath: "/wc-api/v3/orders")
    if rest.lastMethodSuccess != true {

        return

    // When successful, the response status code will equal 200.
    if rest.responseStatusCode.intValue != 200 {
        // Examine the request/response to see what happened.
        print("response status code = \(rest.responseStatusCode.intValue)")
