# 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.
$oauth1 = New-Object 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.
$success = $oauth1.GenNonce(32)

$rest = New-Object 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.
$bUseQueryParams = $true
$success = $rest.SetAuthOAuth1($oauth1,$bUseQueryParams)

# Make the initial connection (without sending a request yet) to the WooCommerce endpoint at your Wordpress blog.
$bTls = $false
$port = 80
$bAutoReconnect = $true
$success = $rest.Connect("your-wordpress-site.com",$port,$bTls,$bAutoReconnect)
if ($success -ne $true) {
    $($rest.LastErrorText)
    exit
}

# 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").
$responseJson = $rest.FullRequestNoBody("GET","/wc-api/v3/orders")
if ($rest.LastMethodSuccess -ne $true) {
    $($rest.LastErrorText)
