httpclient 4.5 https请求跳过证书验证作者：数据无忧 时间：2020-09-18 13:24:53 |
再使用代理IP抓取HTTPS网站的数据过程中，报错：javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target 解决方案：信任所有证书，并通过SslUtil.SslHttpClientBuild()方法获取CloseableHttpClient对象： public class SslUtil { public static CloseableHttpClient SslHttpClientBuild() { Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create().register("http", PlainConnectionSocketFactory.INSTANCE).register("https", trustAllHttpsCertificates()).build(); //创建ConnectionManager，添加Connection配置信息 PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager(socketFactoryRegistry); CloseableHttpClient httpClient = HttpClients.custom().setConnectionManager(connectionManager).build(); return httpClient; } private static SSLConnectionSocketFactory trustAllHttpsCertificates() { SSLConnectionSocketFactory socketFactory = null; TrustManager[] trustAllCerts = new TrustManager[1]; TrustManager tm = new miTM(); trustAllCerts[0] = tm; SSLContext sc = null; try { sc = SSLContext.getInstance("TLS"); sc.init(null, trustAllCerts, null); socketFactory = new SSLConnectionSocketFactory(sc, NoopHostnameVerifier.INSTANCE); // HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory()); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } catch (KeyManagementException e) { e.printStackTrace(); } return socketFactory; } static class miTM implements TrustManager, X509TrustManager { public X509Certificate[] getAcceptedIssuers() { return null; } public void checkServerTrusted(X509Certificate[] certs, String authType) { //don't check } public void checkClientTrusted(X509Certificate[] certs, String authType) { //don't check } } }
