How to call API (Oauth 1.0)?
提问by Sanjaya Pandey
I am trying to call this API (Oauth1.0 standard):
我正在尝试调用此 API（Oauth1.0 标准）：
https://appcenter.intuit.com/api/v1/Connection/Reconnect
https://appcenter.intuit.com/api/v1/Connection/Reconnect
And what I am doing is : (It am working on java)
我正在做的是:(它正在处理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());
}
And, the response what I am getting is:
而且，我得到的回应是：
<?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>
Can you please suggest me what I am missing while creating request for Oauth1.0standard or Please, anyone can provide me the sample code of Oauth1.0request example on that standard.
您能否建议我在创建 Oauth1.0标准请求时缺少什么，或者请任何人向我提供该标准上Oauth1.0请求示例的示例代码。
Thank you very much.
非常感谢你。

This is the working HTTP GET requestcode in java when all keys are in hand. Hope it does your work.
当所有密钥都在手时，这是在 java 中工作的 HTTP GET 请求代码。希望它能完成你的工作。

Here is a builder I created to build the OAuth v1 Authorization header. You may find it useful.
这是我为构建 OAuth v1 授权标头而创建的构建器。你可能会发现它很有用。

Example usage calling Twitter:
调用 Twitter 的示例用法：
String authorizationHeader = new OAuth1AuthorizationHeaderBuilder()
.withMethod("POST")
.withURL("https://api.twitter.com/oauth/access_token")
.withConsumerSecret("twitterConsumerSecret")
.withTokenSecret("your_oauth_token_secret")
.withParameter("oauth_consumer_key", "your_consumer_key")
.withParameter("oauth_token", "your_oauth_token")
.build()
