Java 身份验证不起作用jsonrpc2库

在尝试访问api时，我不断遇到401错误，api需要我提供的用户名和密码。我正在使用jsonrpc2库来实现这一切。这是我的密码：

App.java

 public class App {

public static JSONRPC2Session rpcSession;
private static final String MONERO_URL = "http://localhost:18082/json_rpc";
public static int requestId = 1;
public static JSONRPC2Request request;
public static JSONRPC2Response response;

public static void main(String[] args) throws MalformedURLException, JSONRPC2SessionException
{
  MoneroClient client = new MoneroClient(MONERO_URL); 
  client.getBalance();

}
}

MoneroClient.java

public class MoneroClient {

private int requestId = 0;

private JSONRPC2Session rpcSession;

public MoneroClient(String url) throws MalformedURLException {
    rpcSession = new JSONRPC2Session(new URL(url));

    rpcSession.setRawResponseInspector(new MyInspector());


    rpcSession.setConnectionConfigurator(new BasicAuthenticator());
} 
public BigDecimal getBalance() throws JSONRPC2SessionException {
    BigDecimal balance = null;
    JSONObject result = rpcCall("getbalance", null);
    if (result != null) {
        balance = BigDecimal.valueOf(Long.valueOf("" + result.get("balance")), 12);
        //balance = String.valueOf(result.get("balance"));
    }
    return balance;
}

private JSONObject rpcCall(String method, List<Object> params) throws JSONRPC2SessionException {
    JSONRPC2Request request = new JSONRPC2Request(method, params, ++requestId);
    JSONRPC2Response response = rpcSession.send(request);
    JSONObject result = null;
    if (response.indicatesSuccess()) {
        result = (JSONObject) response.getResult();
    } else {
        // TODO: Throw exception
        System.err.println(response.getError().getMessage());
    }
    return result;
}

HTTP 401响应中是否有WWW Authenticate头，如果设置了，它会说什么？不，我如何设置？好的，我找到了WWW Authenticate头：WWW Authenticate:Digest qop=“auth”，algorithm=MD5，realm=“monero wallet rpc”，nonce=“rewf4crzipbftuazprpbw=”，stale=false Digest qop=“auth”，algorithm=MD5 sess，realm=“monero wallet rpc”，nonce=“rewf4crzipbftuazprpbw==”，stale=false不知道。请尝试查找可以生成md5摘要授权头的库或代码段。在任何情况下，这都超出了JSON-RPC 2.0的范围。

public class BasicAuthenticator implements ConnectionConfigurator
{

    public void configure(HttpURLConnection connection) 
    {
        connection.addRequestProperty("Authorization", "Basic QWxhZGRpbjpPcGVuU2VzYW1l");
    }
}
