How can I use Chilkat to authentication with a server using OAUTH2? I see the the Chilkat Http.G_SvcOauthAccessToken method for getting an OAUTH2 access token from the Google API, but I want to implement OAUTH2 in general for other sites.
OAuth2 requires a means to obtain an access token. Typically, this is done interactively using a web-browser w/ redirects to the site that is the owner of the resource to be accessed. See http://tutorials.jenkov.com/oauth2/overview.html
Using the Chilkat API alone would not be able to obtain an access token because of the interactivity required. The exception is if the resource owner provides a programmatic means, such as what Google API does, to obtain an access token. Chilkat implemented Google's method for obtaining a Google API access token because it is commonly used. For other resources that might provide a programmatic means for obtaining an access token, you would need to implement it directly using Chilkat HTTP and Chilkat RSA for the signing.
