'  It requires the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

'  Assume we've previously obtained an access token and saved it to a JSON file..
Dim jsonToken As New ChilkatJsonObject
Dim success As Long
success = jsonToken.LoadFile("qa_data/tokens/twitter.json")

Dim http As New ChilkatHttp

'  Provide the OAuth 1.0a credentials:
http.OAuth1 = 1
http.OAuthConsumerKey = "TWITTER_CONSUMER_KEY"
http.OAuthConsumerSecret = "TWITTER_CONSUMER_SECRET"
http.OAuthToken = jsonToken.StringOf("oauth_token")
http.OAuthTokenSecret = jsonToken.StringOf("oauth_token_secret")

Dim req As New ChilkatHttpRequest
req.HttpVerb = "POST"
req.ContentType = "multipart/form-data"
req.Path = "/1.1/media/upload.json"

'  Add a JPEG image file to the upload.
Dim fac As New CkFileAccess

Dim response As ChilkatHttpResponse
Set response = http.SynchronousRequest("upload.twitter.com",443,1,req)
If (http.LastMethodSuccess <> 1) Then
    Debug.Print http.LastErrorText
    Exit Sub
End If

Dim jsonResponse As New ChilkatJsonObject

If (response.StatusCode <> 200) Then
    Debug.Print jsonResponse.Emit()

End If

'  Show the successful response:
Debug.Print jsonResponse.Emit()
Debug.Print "Success."

'  A successful JSON response looks like this:

'  	{

'  	    "w": 120,
'  	    "h": 120
'  	  }
'  	}
' 

'  Get the information from the JSON:
Debug.Print "media_id_string = " & jsonResponse.StringOf("media_id_string")
Debug.Print "size = " & jsonResponse.IntOf("size")
Debug.Print "image_type = " & jsonResponse.StringOf("image.image_type")
