如何调用 API (Oauth 1.0)? [英] How to call API (Oauth 1.0)?

问题描述

我正在尝试调用此 API(Oauth1.0 标准):

I am trying to call this API (Oauth1.0 standard):

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

而我正在做的是:(它正在开发 Java)

And what I am doing is : (It am working on 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:

And, the response what I am getting is:

<?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>

您能否建议我在创建 Oauth1.0 标准请求时我缺少什么 标准或请任何人向我提供Oauth1.0 请求示例的示例代码在那个标准上.

Can you please suggest me what I am missing while creating request for Oauth1.0 standard or Please, anyone can provide me the sample code of Oauth1.0 request example on that standard.

非常感谢.
