prepare_refresh_token_form
Description:
public abstract void prepare_refresh_token_form (Source source, string refresh_token, HashTable<string,string> form)
Sets additional form parameters to be used in the POST request when requesting to refresh an access token.
The default implementation sets some values too, namely "refresh_token", "client_id", "client_secret" and "grant_type". These parameters are always provided, even when the interface implementer overrides this method.
The form hash table expects both key and value to be newly allocated strings, which will be freed together with the hash table or
when the key is replaced.
Parameters:
| this | |
| source |
an associated Source |
| refresh_token |
a refresh token to be used |
| form |
form parameters to be used in the POST request |
