Ошибка интеграции Blackberry linkedin при получении OAuth Token

1 голос
/ 23 февраля 2012

Я пытаюсь интегрировать Linkedin в Blackberry.Я следовал инструкциям Linkedin по Получение OAuth-токена .

Я успешно получил токен запроса.После этого я отправляю запрос на получение токена доступа.Затем отображается код ошибки 401. Как устранить ошибку?

Совет по проблеме декодируется в

com.linkedin.security.auth.pub.LoginDeniedInvalidAuthTokenException while obtaining request token for :POST&https%3A%2F%2Fapi.linkedin.com%2Fuas%2Foauth%2FaccessToken&oauth_consumer_key▒ffffffffff%26oauth_nonce%3D8928851959000826448%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1329997670%26oauth_token%3Dc98f4ecf-26b5-44aa-a11f-8384ecdacac0%26oauth_verifier%3D85932%26oauth_version%3D1.0OAU:dkkyeudmhykb|c98f4ecf-26b5-44aa-a11f-8384ecdacac0|*01|*01:1329997670:UDYg4juNLVHzmP7vk/RSfhihLlI=Access tockenem=signature_invalid

, что декодирует встроенный URL-адрес

https://api.linkedin.com/uas/oauth/accessToken&oauth_consumer_key▒ffffffffff&oauth_nonce=8928851959000826448&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1329997670&oauth_token=c98f4ecf-26b5-44aa-a11f-8384ecdacac0&oauth_verifier=85932&oauth_version=1.0OAU:dkkyeudmhykb|c98f4ecf-26b5-44aa-a11f-8384ecdacac0|*01|*01:1329997670:UDYg4juNLVHzmP7vk/RSfhihLlI=

    String header = oauth_header1(url, HttpProtocolConstants.HTTP_METHOD_POST);
    requestTokenUrl = concatURL(url, header);
