// 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.
Chilkat.OAuth1 oauth1 = new Chilkat.OAuth1();
oauth1.ConsumerKey = "WOO_COMMERCE_CONSUMER_KEY";
oauth1.ConsumerSecret = "WOO_COMMERCE_CONSUMER_SECRET";

// 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.
bool success = oauth1.GenNonce(32);

Chilkat.Rest rest = new 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.
bool bUseQueryParams = true;
success = rest.SetAuthOAuth1(oauth1,bUseQueryParams);

// Make the initial connection (without sending a request yet) to the WooCommerce endpoint at your Wordpress blog.
bool bTls = false;
int port = 80;
bool bAutoReconnect = true;
success = await rest.ConnectAsync("your-wordpress-site.com",port,bTls,bAutoReconnect);
if (success != true) {
    Debug.WriteLine(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").
string responseJson = await rest.FullRequestNoBodyAsync("GET","/wc-api/v3/orders");
if (rest.LastMethodSuccess != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

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