httpsclient 自动获取证书 无证书访问 验证过能直接用

首先实现写一个 实现接口SecureProtocolSocketFactory的类。

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() },

        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (KeyManagementException e) {
            e.printStackTrace();
        }
        return sslcontext;
    }

    private SSLContext getSSLContext() {
        if (this.sslcontext == null) {

        }

    public Socket createSocket(Socket socket, String host, int port,
            boolean autoClose) throws IOException, UnknownHostException {

        SocketFactory socketfactory = getSSLContext().getSocketFactory();

            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);
