我有一个问题，任何帮助都很感激。我的测试设备是华硕Nexus 7安卓5.1。我想使用Jetty Websockets连接到web服务器。url使用wss，我在manifest.xml文件中编辑了互联网权限。下面是代码:
import org.eclipse.jetty.websocket.api.Session;
import org.eclipse.jetty.websocket.api.WebSocketAdapter;
import org.eclipse.jetty.util.log.Log;
import org.eclipse.jetty.util.log.Logger;
/**
* Created by Christian on 10.07.2015.
*/
public class Socket extends WebSocketAdapter {
private static final Logger LOG = Log.getLogger(Socket.class);
@Override
public void onWebSocketConnect(Session session) {
super.onWebSocketConnect(session);
LOG.info("onConnect({})", session);
}
@Override
public void onWebSocketText(String message) {
super.onWebSocketText(message);
LOG.info("onMessage() - {}", message);
}
@Override
public void onWebSocketClose(int statusCode, String reason) {
super.onWebSocketClose(statusCode, reason);
LOG.info("onClose({}, {})", statusCode, reason);
}
@Override
public void onWebSocketError(Throwable cause) {
super.onWebSocketError(cause);
LOG.warn(cause);
}
}
这是websocket类。我在我的android应用程序的MainActivity中启动websocket客户端:
URI uri = URI.create("wss://localhost:8600");
SslContextFactory ssl = new SslContextFactory();
ssl.setTrustAll(true);
WebSocketClient client = new WebSocketClient(ssl);
try {
client.start();
Socket socket = new Socket();
ClientUpgradeRequest request = new ClientUpgradeRequest();
Future<Session> fut = client.connect(socket, uri);
} catch (Throwable t) {
LOG.warn(t);
}
编译后，日志显示以下错误，由此我假设服务器无法连接到服务器。

同样的问题。问题似乎是在Android中重新实现SSLParameters，您可以在Android .jar中找到。这个实现甚至有一个名为"endpointIdentificationAlgorithm"的字段，但没有使用，所以我想它将在未来实现。
我做了一个解决方案，通过覆盖"定制"-方法调用丢失的setEndpointIdentificationAlgorithm和删除的行，其余的是原始代码:
this.client = new WebSocketClient(new SslContextFactory(true){
@Override
public void customize(SSLEngine sslEngine) {
SSLParameters sslParams = sslEngine.getSSLParameters();
//sslParams.setEndpointIdentificationAlgorithm(_endpointIdentificationAlgorithm);
sslEngine.setSSLParameters(sslParams);
if (getWantClientAuth())
sslEngine.setWantClientAuth(getWantClientAuth());
if (getNeedClientAuth())
sslEngine.setNeedClientAuth(getNeedClientAuth());
sslEngine.setEnabledCipherSuites(selectCipherSuites(
sslEngine.getEnabledCipherSuites(),
sslEngine.getSupportedCipherSuites()));
sslEngine.setEnabledProtocols(selectProtocols(sslEngine.getEnabledProtocols(),sslEngine.getSupportedProtocols()));
}
});
