如何将http标头添加到Apache Jena QueryEngineHTTP查询？

Question

我尝试使用HTTP标头，以便我可以对我的应用进行身份验证，以查询ORCID（http://orcid.org）公共API。我创建了这样的标题：

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);

但我不知道如何将这些标题放入我的查询中。我这样写我的查询：

QueryExecution execution = new QueryEngineHTTP(endpoint, query);

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

Apache Jena现在（v3.1.1及更高版本）提供了通过必要的安全设置传递HttpClient的方法。

... set up an appropriate HttpClient for authentication ....

QueryExecution execution = QueryExecutionFactory.sparqlService( ... , httpClient)
