如何调用API（Oauth 1.0）？

我试图称这个API（Oauth1.0标准）：

https://appcenter.intuit.com/api/v1/Connection/Reconnect

我正在做的是:(它正在研究java）

Base64Encoder baseEncoder = Base64Encoder.getInstance(); 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(OAUTHTOKEN).append("\""); headerReq.append(", oauth_consumer_key=\"").append(CUNSUMER_KEY).append("\""); headerReq.append(", oauth_signature_method=\"base64\""); headerReq.append(", oauth_signature=\"") .append(baseEncoder.encode(PropsUtil.get(OAUTH_CONSUMER_SECRET).getBytes())) .append(baseEncoder.encode("&".getBytes())) .append(baseEncoder.encode(symmetricEncrypter.decryptData(OAUTH_TOKEN_SECRET).getBytes())).append("\""); headerReq.append(", oauth_version=\"1.0\""); httpGet.addHeader("Authorization", headerReq.toString()); CloseableHttpResponse response = httpclient.execute(httpGet); try { System.out.println("Responsee::"+ response.getStatusLine()); } 

而且，我得到的回应是：

   This API requires Authorization. 22 

你能否在创建Oauth1.0标准请求时向我建议我缺少什么，或者，任何人都可以提供该标准的Oauth1.0请求示例的示例代码。

非常感谢你。

当所有密钥都在手中时，这是java中的工作HTTP GET请求代码。 希望它能完成你的工作。
