如何將http標頭添加到Apache Jena QueryEngineHTTP查詢？

Question

我正在嘗試使用HTTP標頭，以便我可以驗證我的應用程序以查詢ORCID（http://orcid.org）公共API。我創建這樣的標題：

HttpOptions httpOptions = new HttpOptions(); 
Header contentTypeHeader = new BasicHeader("Content-Type", "application/orcid+json"); 
Header authorizationHeader = new BasicHeader("Authorization", "Bearer 5266384f-0567-43f0-9cd4-bc6f6a5dc3ea"); 
Header[] headers = new Header[2]; 
headers[1] = contentTypeHeader; 
headers[2] = authorizationHeader; 
httpOptions.setHeaders(headers); 

但我不知道如何將這些標題放到我的查詢中。我在寫我的查詢是這樣的：

QueryExecution execution = new QueryEngineHTTP(endpoint, query); 

使用org.apache.jena.sparql.engine.http.QueryEngineHTTP

阿帕奇現在耶拿（V3.1.1及更高版本）提供的手段來傳遞在具有必要安全設置的HttpClient中。
