java websocket client ssl(wss)

1.如何找一个适合自己的websocket客户端？请看http://en.wikipedia.org/wiki/Comparison_of_WebSocket_implementations

2.因为要在android上使用websocket，要求使用wss，这时候我就选择了java_websocket(http://java-websocket.org/)

这个ws客户端对wss支持不好，源码中的wss client 还要使用证书。我的想法是不验证证书。将他的代码稍作修改：

import java.io.BufferedReader;import java.io.File;import java.io.FileInputStream;import java.io.InputStreamReader;import java.net.URI;import java.security.KeyStore;import javax.net.ssl.KeyManagerFactory;import javax.net.ssl.SSLContext;import javax.net.ssl.TrustManagerFactory;import org.java_websocket.WebSocket;import org.java_websocket.client.DefaultSSLWebSocketClientFactory;import org.java_websocket.client.WebSocketClient;import org.java_websocket.handshake.ServerHandshake;class WebSocketChatClient extends WebSocketClient {public WebSocketChatClient( URI serverUri ) {super( serverUri );}@Overridepublic void onOpen( ServerHandshake handshakedata ) {System.out.println( "Connected" );}@Overridepublic void onMessage( String message ) {System.out.println( "got: " + message );}@Overridepublic void onClose( int code, String reason, boolean remote ) {System.out.println( "Disconnected" );System.exit( 0 );}@Overridepublic void onError( Exception ex ) {ex.printStackTrace();}}public class SSLClientExample {

// always verify the host - dont check for certificate    final static HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {        public boolean verify(String hostname, SSLSession session) {            return true;        }    };    /**     * Trust every server - dont check for any certificate     */    private static void trustAllHosts(AppWebSocketClient appClient) {        // Create a trust manager that does not validate certificate chains        TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {            public java.security.cert.X509Certificate[] getAcceptedIssuers() {                return new java.security.cert.X509Certificate[]{};            }            public void checkClientTrusted(X509Certificate[] chain,                                           String authType) throws CertificateException {            }            public void checkServerTrusted(X509Certificate[] chain,                                           String authType) throws CertificateException {            }        }};        // Install the all-trusting trust manager        try {            SSLContext sc = SSLContext.getInstance("TLS");            sc.init(null, trustAllCerts, new java.security.SecureRandom());            appClient.setWebSocketFactory(new DefaultSSLWebSocketClientFactory(sc));        } catch (Exception e) {            e.printStackTrace();        }    }public static void main( String[] args ) throws Exception {WebSocket.DEBUG = true;WebSocketChatClient chatclient = new WebSocketChatClient( new URI( "wss://localhost:8887" ) );trustAllHosts(appClient);chatclient.connectBlocking();BufferedReader reader = new BufferedReader( new InputStreamReader( System.in ) );while ( true ) {String line = reader.readLine();if( line.equals( "close" ) ) {chatclient.close();} else {chatclient.send( line );}}}}
