Examples with HttpClient java.net.http.HttpClient used on opensource projects

Example 1 with HttpClient

use of java.net.http.HttpClient in project jena by apache.

the class RemoteEndpointDriver method connect.

@Override
protected JenaConnection connect(Properties props, int compatibilityLevel) throws SQLException {
    String queryEndpoint = props.getProperty(PARAM_QUERY_ENDPOINT);
    String updateEndpoint = props.getProperty(PARAM_UPDATE_ENDPOINT);
    // Validate at least one endpoint present
    if (queryEndpoint == null && updateEndpoint == null)
        throw new SQLException("At least one of the " + PARAM_QUERY_ENDPOINT + " or " + PARAM_UPDATE_ENDPOINT + " connection parameters must be specified to make a remote connection");
    // Gather dataset related parameters
    List<String> defaultGraphs = this.getValues(props, PARAM_DEFAULT_GRAPH_URI);
    List<String> namedGraphs = this.getValues(props, PARAM_NAMED_GRAPH_URI);
    List<String> usingGraphs = this.getValues(props, PARAM_USING_GRAPH_URI);
    List<String> usingNamedGraphs = this.getValues(props, PARAM_USING_NAMED_GRAPH_URI);
    // Authentication settings
    HttpClient client = this.configureClient(props);
    // Result Types
    String selectResultsType = props.getProperty(PARAM_SELECT_RESULTS_TYPE, null);
    String modelResultsType = props.getProperty(PARAM_MODEL_RESULTS_TYPE, null);
    // Create connection
    return openConnection(queryEndpoint, updateEndpoint, defaultGraphs, namedGraphs, usingGraphs, usingNamedGraphs, client, JenaConnection.DEFAULT_HOLDABILITY, compatibilityLevel, selectResultsType, modelResultsType);
}

Example 2 with HttpClient

use of java.net.http.HttpClient in project jena by apache.

the class ExecHTTPBuilder method build.

public final X build() {
    Objects.requireNonNull(serviceURL, "No service URL");
    if (queryString == null && query == null)
        throw new QueryException("No query for QueryExecHTTP");
    HttpClient hClient = HttpEnv.getHttpClient(serviceURL, httpClient);
    Query queryActual = query;
    String queryStringActual = queryString;
    if (substitutionMap != null && !substitutionMap.isEmpty()) {
        if (query == null)
            throw new QueryException("Substitution only supported if a Query object was provided");
        queryActual = QueryTransformOps.transform(query, substitutionMap);
        queryStringActual = queryActual.toString();
    }
    Context cxt = contextAcc.context();
    return buildX(hClient, queryActual, queryStringActual, cxt);
}

Example 3 with HttpClient

use of java.net.http.HttpClient in project jena by apache.

the class ExecUpdateHTTPBuilder method build.

public X build() {
    Objects.requireNonNull(serviceURL, "No service URL");
    if (updateOperations == null && updateString == null)
        throw new QueryException("No update for UpdateExecutionHTTP");
    if (updateOperations != null && updateString != null)
        throw new InternalErrorException("UpdateRequest and update string");
    HttpClient hClient = HttpEnv.getHttpClient(serviceURL, httpClient);
    UpdateRequest updateActual = updateOperations;
    if (substitutionMap != null && !substitutionMap.isEmpty()) {
        if (updateActual == null)
            throw new UpdateException("Substitution only supported if an UpdateRequest object was provided");
        updateActual = UpdateTransformOps.transform(updateActual, substitutionMap);
    }
    Context cxt = (context != null) ? context : ARQ.getContext().copy();
    return buildX(hClient, updateActual, cxt);
}

Example 4 with HttpClient

use of java.net.http.HttpClient in project jena by apache.

the class ExAuth02_QueryExecutionPW method exampleQueryAuthWithHttpClient.

// HttpClient
public static void exampleQueryAuthWithHttpClient() {
    System.out.println();
    System.out.println("HttpClient + QueryExecutionHTTP");
    Authenticator authenticator = AuthLib.authenticator("u", "p");
    HttpClient httpClient = HttpClient.newBuilder().connectTimeout(Duration.ofSeconds(10)).authenticator(authenticator).build();
    try (QueryExecution qexec = QueryExecutionHTTP.service(dataURL).httpClient(httpClient).endpoint(dataURL).queryString("ASK{}").build()) {
        qexec.execAsk();
    }
}

Example 5 with HttpClient

    System.out.println("Custom HttpClient + SERVICE call");
    Authenticator authenticator = AuthLib.authenticator("u", "p");
    HttpClient httpClient = HttpClient.newBuilder().connectTimeout(Duration.ofSeconds(10)).authenticator(authenticator).build();
    Context cxt = ContextAccumulator.newBuilder().set(ARQ.httpQueryClient, httpClient).context();
    Query query = QueryFactory.create("SELECT * { SERVICE <" + dataURL + "> { ?s ?p ?o } }");
    Dataset emptyLocal = DatasetFactory.empty();
    try (QueryExecution qExec = QueryExecution.create().query(query).dataset(emptyLocal).context(cxt).build()) {
        System.out.println("Call using SERVICE...");
        ResultSet rs = qExec.execSelect();
