ActiveX for 32-bit and 64-bit Windows

'  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.
Dim oauth1 As New ChilkatOAuth1
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.
Dim success As Long
success = oauth1.GenNonce(32)

Dim rest As New ChilkatRest

'  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.
Dim bUseQueryParams As Long
bUseQueryParams = 1
success = rest.SetAuthOAuth1(oauth1,bUseQueryParams)

'  Make the initial connection (without sending a request yet) to the WooCommerce endpoint at your Wordpress blog.
Dim bTls As Long
bTls = 0
Dim port As Long
port = 80
Dim bAutoReconnect As Long
bAutoReconnect = 1
success = rest.Connect("your-wordpress-site.com",port,bTls,bAutoReconnect)
If (success <> 1) Then
    Text1.Text = Text1.Text & rest.LastErrorText & vbCrLf
    Exit Sub
End If

'  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").
Dim responseJson As String
responseJson = rest.FullRequestNoBody("GET","/wc-api/v3/orders")
If (rest.LastMethodSuccess <> 1) Then
    Text1.Text = Text1.Text & rest.LastErrorText & vbCrLf
    Exit Sub
End If

'  When successful, the response status code will equal 200.
If (rest.ResponseStatusCode <> 200) Then
    '  Examine the request/response to see what happened.
    Text1.Text = Text1.Text & "response status code = " & rest.ResponseStatusCode & vbCrLf
    Text1.Text = Text1.Text & "response status text = " & rest.ResponseStatusText & vbCrLf
    Text1.Text = Text1.Text & "response header: " & rest.ResponseHeader & vbCrLf
    Text1.Text = Text1.Text & "response body (if any): " & responseJson & vbCrLf
    Text1.Text = Text1.Text & "---" & vbCrLf
    Text1.Text = Text1.Text & "LastRequestStartLine: " & rest.LastRequestStartLine & vbCrLf
    Text1.Text = Text1.Text & "LastRequestHeader: " & rest.LastRequestHeader & vbCrLf
    Exit Sub
End If

Text1.Text = Text1.Text & responseJson & vbCrLf
Text1.Text = Text1.Text & "Success." & vbCrLf
