How do I call the API (Oauth 1.0)?
I'm trying to call this API (Oauth1.0 standard):
https://appcenter.intuit.com/api/v1/Connection/Reconnect
And what am I doing: (it is 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());
}
And the answer I get 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>
Can you suggest me what I am missing when making a request for Oauth1.0 , or can someone provide me with some sample code for an Oauth1.0 example on this standard.
Many thanks.
