Apache HTTP Client loadTrust材质不工作

Question

首先，源代码中没有注释。

<代码>组织。阿帕奇。hc。core5.ssl。SSLContextBuilder#loadTrustMaterial（org.apache.hc.core5.ssl.TrustStrategy）

public SSLContextBuilder loadTrustMaterial(
        final TrustStrategy trustStrategy) throws NoSuchAlgorithmException, KeyStoreException {
    return loadTrustMaterial(null, trustStrategy);
}

这是代码会触发混淆行为，与apache官方演示Apache演示相同

@Test
void customStrategy() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException, IOException, ParseException {

    SSLContextBuilder sslContextBuilder = SSLContexts.custom();
    sslContextBuilder.loadTrustMaterial((chain, authType) -> false);
    SSLContext sslcontext = sslContextBuilder.build();

    SSLConnectionSocketFactoryBuilder sslConnectionSocketFactoryBuilder = SSLConnectionSocketFactoryBuilder.create();
    sslConnectionSocketFactoryBuilder.setSslContext(sslcontext);
    sslConnectionSocketFactoryBuilder.setTlsVersions(TLS.V_1_2);
    SSLConnectionSocketFactory sslConnectionSocketFactory = sslConnectionSocketFactoryBuilder.build();

    PoolingHttpClientConnectionManagerBuilder poolingHttpClientConnectionManagerBuilder = PoolingHttpClientConnectionManagerBuilder.create();
    poolingHttpClientConnectionManagerBuilder.setSSLSocketFactory(sslConnectionSocketFactory);
    HttpClientConnectionManager httpClientConnectionManager = poolingHttpClientConnectionManagerBuilder.build();

    HttpClientBuilder httpClientBuilder = HttpClients.custom();
    httpClientBuilder.setConnectionManager(httpClientConnectionManager);
    CloseableHttpClient closeableHttpClient = httpClientBuilder.build();

    HttpClientContext clientContext = HttpClientContext.create();

    CloseableHttpResponse response = closeableHttpClient.execute(new HttpGet("https://www.baidu.com"), clientContext);

    System.out.println("BODY-Length " + EntityUtils.toString(response.getEntity()).length());

    SSLSession sslSession = clientContext.getSSLSession();

    System.out.println(sslSession.getPeerHost() + ":" + sslSession.getPeerPort());
}

输出为：

... ...
BODY-Length 2443
www.baidu.com:443

甚至我在自定义信任策略中直接返回false。

sslContextBuilder.loadTrustMaterial((chain, authType) -> {
    throw new CertificateException();
});

这将中断连接，但我不认为如果接口返回false，但只有在异常正确使用时才会中断。

问题：为什么返回false不起作用？Thorw Exection让我感觉不对，这是设计吗？

请参阅信任策略的javadocs。如果信任策略从受信任方法返回false，则证书验证由在SSL上下文中配置的信任管理器执行。
