httpsclient 自动获取证书 无证书访问
首先实现写一个 实现接口SecureProtocolSocketFactory的类。
/** *ClassName: bcde *date: 2015年2月26日 下午4:51:01 * *@author limh *@since JDK 1.7 */ import java.io.IOException; import java.net.InetAddress; import java.net.InetSocketAddress; import java.net.Socket; import java.net.SocketAddress; import java.net.UnknownHostException; import java.security.KeyManagementException; import java.security.NoSuchAlgorithmException; import java.security.cert.CertificateException; import java.security.cert.X509Certificate; import javax.net.SocketFactory; import javax.net.ssl.SSLContext; import javax.net.ssl.TrustManager; import javax.net.ssl.X509TrustManager; import org.apache.commons.httpclient.ConnectTimeoutException; import org.apache.commons.httpclient.params.HttpConnectionParams; import org.apache.commons.httpclient.protocol.SecureProtocolSocketFactory; /** * MySecureProtocolSocketFactory.java.java Create on 2012-9-26下午1:15:03 * * * Copyright (c) 2012 by MTA. * * @author lmeteor * @Email [email protected] * @description 自定义的socket factory 实现自动接受证书 * @version 1.0 */ public class MySecureProtocolSocketFactory implements SecureProtocolSocketFactory { private SSLContext sslcontext = null; private SSLContext createSSLContext() { SSLContext sslcontext = null; try { sslcontext = SSLContext.getInstance("SSL"); sslcontext.init(null, new TrustManager[] { new TrustAnyTrustManager() }, new java.security.SecureRandom()); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } catch (KeyManagementException e) { e.printStackTrace(); } return sslcontext; } private SSLContext getSSLContext() { if (this.sslcontext == null) { this.sslcontext = createSSLContext(); } return this.sslcontext; } public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException { return getSSLContext().getSocketFactory().createSocket(socket, host, port, autoClose); } public Socket createSocket(String host, int port) throws IOException, UnknownHostException { return getSSLContext().getSocketFactory().createSocket(host, port); } public Socket createSocket(String host, int port, InetAddress clientHost, int clientPort) throws IOException, UnknownHostException { return getSSLContext().getSocketFactory().createSocket(host, port, clientHost, clientPort); } public Socket createSocket(String host, int port, InetAddress localAddress, int localPort, HttpConnectionParams params) throws IOException, UnknownHostException, ConnectTimeoutException { if (params == null) { throw new IllegalArgumentException("Parameters may not be null"); } int timeout = params.getConnectionTimeout(); SocketFactory socketfactory = getSSLContext().getSocketFactory(); if (timeout == 0) { return socketfactory.createSocket(host, port, localAddress, localPort); } else { Socket socket = socketfactory.createSocket(); SocketAddress localaddr = new InetSocketAddress(localAddress, localPort); SocketAddress remoteaddr = new InetSocketAddress(host, port); socket.bind(localaddr); socket.connect(remoteaddr, timeout); return socket; } } // 自定义私有类 private static class TrustAnyTrustManager implements X509TrustManager { public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException { } public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException { } public X509Certificate[] getAcceptedIssuers() { return new X509Certificate[] {}; } } }
调用时,只需要在生成 httpclient之前,注册刚才创建的https 协议对象,之后 httpsClient的用法正常使用即可。
ProtocolSocketFactory fcty = new MySecureProtocolSocketFactory(); //注册刚才创建的https 协议对象 Protocol.registerProtocol("https", new Protocol("https", fcty, 443)); HttpClient httpclient = new HttpClient(); //httpsClient的用法正常使用 PostMethod method = new PostMethod(URL); httpclient.executeMethod(method);
