Olá a todos,
Estou tentando acessar o Fluig via OAuth 1.0 para consumir servicos REST, mas estou esbarrando na autenticação. Do lado do Fluig, foi criada a aplicação para permitir o consumo dos serviços REST, gerando as chaves "Consumer key" e "Consumer Secret". O problema ocorre quando minha aplicação solicita um token. O Fluig server é acessado via https, como as chamadas OAuth são via http, acredito que seja algum problema relativo aos redirecionamentos internos no servidor, como sugere o segundo exemplo que postei logo abaixo.
Segui este exemplo aqui: TesteClient
E ao fazer as devidas configurações, tenho esta exceção:
oauth.signpost.exception.OAuthCommunicationException: Communication with the service provider failed: Server returned HTTP response code: 411 for URL: http://portal.myfluig.com.br:80/portal/api/rest/oauth/request_token
