oauth - 如何调用intuit connect api(OAuth 1.0)？

Question

我正在我的应用程序上进行 intuit 集成。现在，我面临一个关于调用 intuit 的 reconnect api 的问题。我正在关注此引用:http://oauth.net/core/1.0a/

我正在尝试使用这段代码::

Base64Encoder baseEncoder = Base64Encoder.getInstance();
            Intuit intuit = IntuitLocalServiceUtil.getIntuit();// this is object, which stores the oauth Token and Oauth token secret. 
            CloseableHttpClient httpclient = HttpClients.createDefault();
            HttpGet httpGet = new HttpGet("https://appcenter.intuit.com/api/v1/connection/reconnect");
            StringBuilder headerReq = new StringBuilder();
            headerReq.append("OAuth ");
            headerReq.append("oauth_token=\"").append(intuit.getOauthToken()).append("\"");
            headerReq.append(", oauth_consumer_key=\"").append(CommonConstants.INTUIT_QB_OAUTH_CONSUMER_KEY).append("\"");
            headerReq.append(", oauth_signature_method=\"base64\"");
            headerReq.append(", oauth_signature=\"")
                    .append(baseEncoder.encode(PropsUtil.get(CommonConstants.INTUIT_QB_OAUTH_CONSUMER_SECRET).getBytes()))
                    .append(baseEncoder.encode("&".getBytes()))
                    .append(baseEncoder.encode(symmetricEncrypter.decryptData(intuit.getOauthTokenSecret()).getBytes())).append("\"");

            headerReq.append(", oauth_version=\"1.0\"");
            httpGet.addHeader("Authorization", headerReq.toString());
            System.out.println("Header Rwquesssssssssssst::::::" + headerReq.toString());
            CloseableHttpResponse response = httpclient.execute(httpGet);
            try {
                System.out.println("Responsee::"+ response.getStatusLine());
}

每次我收到这样的回复时:

<?xml version="1.0" encoding="utf-8"?>
<PlatformResponse xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://platform.intuit.com/api/v1">
  <ErrorMessage>This API requires Authorization.</ErrorMessage>
  <ErrorCode>22</ErrorCode>
  <ServerTime>2014-08-16T18:15:45.6417185Z</ServerTime>
</PlatformResponse>
<?xml version="1.0" encoding="utf-8"?>
<PlatformResponse xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://platform.intuit.com/api/v1">
  <ErrorMessage>Authentication required</ErrorMessage>
  <ErrorCode>22</ErrorCode>
  <ServerTime>2014-08-16T18:15:47.3382208Z</ServerTime>
</PlatformResponse>

我确实使用 postman 测试了同样的事情，但我在响应时遇到了相同类型的错误。 我确信我的 key 是有效的并且它们现在正在工作。

(PS:我知道，这些 key 只能在 150 到 180 天内重新生成，但我预计 intuit api 会出现窗口绑定(bind)异常，但我没有收到这些类型的有效错误，我只收到身份验证错误。)

谢谢。

由于因纽特人的JAVA devkit有一个bug，所以使用SignPost解决了这个问题。
