requestTemporaryCredentials method

Future<AuthorizationResponse> requestTemporaryCredentials([ String? callbackURI ])

Obtain a set of temporary credentials from the server. http://tools.ietf.org/html/rfc5849#section-2.1

If not callbackURI passed, authentication becomes PIN-based.

Implementation

Future<AuthorizationResponse> requestTemporaryCredentials([String? callbackURI]) async {
  callbackURI ??= 'oob';
  final Map<String, String> additionalParams = <String, String>{'oauth_callback': callbackURI};
  final AuthorizationHeaderBuilder ahb = AuthorizationHeaderBuilder();
  ahb.signatureMethod = _platform.signatureMethod;
  ahb.clientCredentials = _clientCredentials;
  ahb.method = 'POST';
  ahb.url = _platform.temporaryCredentialsRequestURI;
  ahb.additionalParameters = additionalParams;

//    print("Requisitanto token to: "+_platform.temporaryCredentialsRequestURI);
//    print("Authorization: "+ahb.build().toString());

  Uri temporaryCredentialsRequestURI = Uri.parse(_platform.temporaryCredentialsRequestURI);

  final http.Response res = await _httpClient.post(temporaryCredentialsRequestURI, headers: <String, String>{'Authorization': ahb.build().toString()});

//    print('Resposta statusCode: '+res.statusCode.toString());
//    print("Resposta body: "+res.body);

  if (res.statusCode != 200) {
    throw StateError(res.body);
  }

  final Map<String, String> params = Uri.splitQueryString(res.body);

  return AuthorizationResponse.fromMap(params);
