GoogleRequest Component

Properties Methods Events Configuration Settings Errors

The GoogleRequest component extends the existing functionality.

Syntax

nsoftware.InGoogle.Googlerequest

Remarks

The GoogleRequest component may be used to form and parse JSON based requests and response to extend the existing functionality of the toolkit.

When making requests the PostData property should be set to the body of the request. Call the Post method to post the data to the server.

When the response is returned the XPath properties such as XPath, XText, XElement, etc may be used to navigate the response.

This service supports authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth component or a separate process. Once complete you should have an authorization string which looks like:

Bearer ya29.AHES6ZSZEJzATdZYjeihDn5W-VrXSsxEZu5p0pclxGdKKQ

Assign this value to the Authorization property before attempting any operations. Consult the Google documentation for this particular service for more information about supported scope values and more details on OAuth authentication.
