如何使用Jersey Client API将GET请求发送到运行HTTPS协议的服务器 . 我可以使用任何示例代码吗？
如此构建您的客户
HostnameVerifier hostnameVerifier = HttpsURLConnection.getDefaultHostnameVerifier(); ClientConfig config = new DefaultClientConfig(); SSLContext ctx = SSLContext.getInstance("SSL"); ctx.init(null, myTrustManager, null); config.getProperties().put(HTTPSProperties.PROPERTY_HTTPS_PROPERTIES, new HTTPSProperties(hostnameVerifier, ctx)); Client client = Client.create(config);

有关设置证书的信息，请参阅这个很好回答的SO问题：Using HTTPS with REST in Java
如果您使用的是Java 6,7和8，则使用Jersey客户端的HTTPS有两个不同的版本
SSLContext sc = SSLContext.getInstance("SSL");
如果使用java 8那么
SSLContext sc = SSLContext.getInstance("TLSv1"); System.setProperty("https.protocols", "TLSv1");

对于Jersey 2，您需要修改代码：
return ClientBuilder.newBuilder() .withConfig(config) .hostnameVerifier(new TrustAllHostNameVerifier()) .sslContext(ctx) .build();

在这里唤醒一个死的问题，但提供的答案不适用于jdk 7（我在某处读到了Oracle工程师的错误，但尚未修复） . 除了@Ryan提供的链接外，您还必须添加：
System.setProperty（“jsse.enableSNIExtension”，“false”）;
（由许多stackoverflow答案结合在一起来解决这个问题）
完整的代码如下所示对我有用（没有设置系统属性，Client Config对我不起作用）：
import java.security.SecureRandom; import java.security.cert.CertificateException; import java.security.cert.X509Certificate; import javax.net.ssl.HostnameVerifier; import javax.net.ssl.HttpsURLConnection; import javax.net.ssl.SSLContext; import javax.net.ssl.SSLSession; import javax.net.ssl.TrustManager; import javax.net.ssl.X509TrustManager; import com.sun.jersey.api.client.Client; import com.sun.jersey.api.client.config.ClientConfig; import com.sun.jersey.api.client.config.DefaultClientConfig; import com.sun.jersey.client.urlconnection.HTTPSProperties; public class ClientHelper { public static ClientConfig configureClient() { System.setProperty("jsse.enableSNIExtension", "false"); TrustManager[] certs = new TrustManager[] { new X509TrustManager() { @Override public X509Certificate[] getAcceptedIssuers() { return null; } @Override public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException { } @Override public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException { } } }; SSLContext ctx = null; try { ctx = SSLContext.getInstance("SSL"); ctx.init(null, certs, new SecureRandom()); } catch (java.security.GeneralSecurityException ex) { } HttpsURLConnection.setDefaultSSLSocketFactory(ctx.getSocketFactory()); ClientConfig config = new DefaultClientConfig(); try { config.getProperties().put(HTTPSProperties.PROPERTY_HTTPS_PROPERTIES, new HTTPSProperties( new HostnameVerifier() { @Override public boolean verify(String hostname, SSLSession session) { return true; } }, ctx)); } catch (Exception e) { } return config; } public static Client createClient() { return Client.create(ClientHelper.configureClient()); }
如果你使用的是Java 8，那么Jersey2的版本比Aleksandr提供的答案要短 .
SSLContext sslContext = null; try { sslContext = SSLContext.getInstance("SSL"); // Create a new X509TrustManager sslContext.init(null, getTrustManager(), null); } catch (NoSuchAlgorithmException | KeyManagementException e) { throw e; } final Client client = ClientBuilder.newBuilder().hostnameVerifier((s, session) -> true) .sslContext(sslContext).build(); return client; private TrustManager[] getTrustManager() { return new TrustManager[] { new X509TrustManager() { @Override public X509Certificate[] getAcceptedIssuers() { return null; } @Override public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException { } @Override public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException { } } }; }
