Gets a request token from the provider.

Parameters

string $endpoint: Optional. The endpoint path for the provider.

If you provide the full URL (e.g. "http://example.com/oauth/request_token"), then it will be used.
If you provide only the path (e.g. "oauth/request_token"), it will be converted into a full URL by prepending the provider_url.
If you provide nothing it will default to '/oauth/request_token'.

array $options: An associative array of additional optional options, with the following keys:

'params' An associative array of parameters that should be included in the request.
'realm' A string to be used as the http authentication realm in the request.
'get' (default FALSE) Whether to use GET as the HTTP-method instead of POST.
'callback' A full URL of where the user should be sent after the request token has been authorized. Only used by versions higher than OAUTH_COMMON_VERSION_1.
'force_port' A port number that is forced when creating normalized URL for calculating signature.

Return value

DrupalOAuthToken The returned request token.
