我是一个长期的读者和第一次使用所以请对我放轻松。

我正在尝试将抢先式身份验证与 javax.ws.rs.client.Client 一起使用。我已经使用 HTTPClient 进行了这项工作，但我不知道如何使用 JAX 身份验证器来完成同样的工作。

    HttpClient client = new HttpClient();
    client.getParams().setAuthenticationPreemptive(true);
    Credentials creds = new UsernamePasswordCredentials("user", "pass");
    client.getState().setCredentials(AuthScope.ANY, creds);

我确实有使用 JAX 的基本身份验证。这是我的客户：

    public HttpsConnection() {
        // configure ssl
        final SslConfigurator sslConfig = SslConfigurator.newInstance().keyStoreFile(keyStore).keyPassword("pass");

        final HostnameVerifier hostnameVerifier = new HostnameVerifier() {

            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        };

        final SSLContext sslContext = sslConfig.createSSLContext();

        // configure client
        final Client client = ClientBuilder.newBuilder().sslContext(sslContext).hostnameVerifier(hostnameVerifier)
            .register(new Authenticator(username, password)).register(JacksonFeature.class)
            .register(new JsonObjectMapper()).build();

        WebTarget target = client.target(base_url);
    }

这是我的身份验证过滤器：

public class Authenticator implements ClientRequestFilter {

    private final String user;
    private final String password;

    public Authenticator(String user, String password) {
        this.user = user;
        this.password = password;
    }

    public void filter(ClientRequestContext requestContext) throws IOException {
        MultivaluedMap<String, Object> headers = requestContext.getHeaders();
        final String basicAuthentication = getBasicAuthentication();
        headers.add("Authorization", basicAuthentication);
    }

    private String getBasicAuthentication() {
        String token = this.user + ":" + this.password;
        try {
            return "Basic " + DatatypeConverter.printBase64Binary(token.getBytes("UTF-8"));
        } catch (UnsupportedEncodingException ex) {
            throw new IllegalStateException("Cannot encode with UTF-8", ex);
        }
    }
}

谁能给我一个使用 UsernamePasswordCredentials 和抢先身份验证的例子，就像我在上面对 HTTPClient 所做的那样？我必须在谷歌上搜索所有错误的东西，因为我找不到一个例子。

如果我的帖子完全糟糕，请在它被 OP 关闭之前告诉我 =)
