连接到安全的 websocket

Question

我正在尝试使用 Jetty（或任何其他库）连接到安全的 websocket。

问题是我收到 "No trusted certificate found" 错误。我正在使用通过 keytool 生成的自签名证书。可以做什么？

import java.net.URI;
import java.util.concurrent.Future;

import org.eclipse.jetty.util.resource.Resource;
import org.eclipse.jetty.util.ssl.SslContextFactory;
import org.eclipse.jetty.websocket.api.Session;
import org.eclipse.jetty.websocket.api.WebSocketAdapter;
import org.eclipse.jetty.websocket.client.WebSocketClient;

public class Socket extends WebSocketAdapter{

    public static void main(String[] args) {
        String url = "wss://qa.sockets.stackexchange.com/"; //or "wss://echo.websocket.org"
        // making sure the the jvm find keystore
        String JAVASEC="C:/Program Files/Java/jdk1.8.0_25/jre/lib/security/";
        System.setProperty("javax.net.ssl.keyStore", JAVASEC+"keystore.jks");
        System.setProperty("javax.net.ssl.trustStore", JAVASEC+"cacerts.jks");
        System.setProperty("javax.net.ssl.keyStorePassword", "changeit");

        System.out.println(System.getProperty("javax.net.ssl.trustStore"));
        SslContextFactory sslContextFactory = new SslContextFactory();
        Resource keyStoreResource = Resource.newResource(Socket.class.getResource("/keystore.jks"));//generated with keytool
        sslContextFactory.setKeyStoreResource(keyStoreResource);
        sslContextFactory.setKeyStorePassword("password");
        sslContextFactory.setKeyManagerPassword("password");
        WebSocketClient client = new WebSocketClient(sslContextFactory);
        try{
            client.start();
            Socket socket = new Socket();
            Future<Session> fut = client.connect(socket,URI.create(url));
            Session session = fut.get();
            session.getRemote().sendString("Hello");
        }
        catch (Throwable t){
            t.printStackTrace(System.err);
        }
    }


    @Override
    public void onWebSocketConnect(Session sess){
        super.onWebSocketConnect(sess);
        System.out.println("Socket Connected: " + sess);
    }

    @Override
    public void onWebSocketText(String message){
        super.onWebSocketText(message);
        System.out.println("Received TEXT message: " + message);
    }

    @Override
    public void onWebSocketClose(int statusCode, String reason){
        super.onWebSocketClose(statusCode,reason);
        System.out.println("Socket Closed: [" + statusCode + "] " + reason);
    }

    @Override
    public void onWebSocketError(Throwable cause){
        super.onWebSocketError(cause);
        cause.printStackTrace(System.err);
    }
}

这是对 Tyrus websocket 客户端的尝试，我没有收到 SSL 错误，但它没有打印任何内容：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URI;
import java.net.URISyntaxException;

        ClientManager client = ClientManager.createClient();

        //System.getProperties().put("javax.net.debug", "all");
        final SSLContextConfigurator defaultConfig = new SSLContextConfigurator();

        defaultConfig.retrieve(System.getProperties());
            // or setup SSLContextConfigurator using its API.

        SSLEngineConfigurator sslEngineConfigurator =
            new SSLEngineConfigurator(defaultConfig, true, false, false);
        client.getProperties().put(GrizzlyEngine.SSL_ENGINE_CONFIGURATOR,
            sslEngineConfigurator);
        Session session = null;
        final ClientEndpointConfig cec = ClientEndpointConfig.Builder.create().build();

        try {
            session = client.connectToServer(ClientWebSocketEndpoint.class, cec, new URI("wss://qa.sockets.stackexchange.com/"));// or "wss://echo.websocket.org"

        } catch (DeploymentException | URISyntaxException e) {
            e.printStackTrace();
        } finally {
            if (session != null && session.isOpen())
                session.close(new CloseReason(CloseReason.CloseCodes.GOING_AWAY, "Bye"));

        }

        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        br.readLine();
    }

    @Override
    public void onOpen(Session session, EndpointConfig config) {
        session.addMessageHandler(new MessageHandler.Whole<String>() {

            @Override
            public void onMessage(String message) {
                System.out.println("Received message: "+message);
            }
        });
        try {
            session.getBasicRemote().sendText("1-questions-active");
            session.getBasicRemote().sendText("155-questions-active");
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }
}

相比之下，JS/node 中的这个简单代码有效

var WebSocket = require('ws')
  , ws = new WebSocket('wss://qa.sockets.stackexchange.com/');//"wss://echo.websocket.org"

ws.on('message', function(message) {
    console.log('received: %s', message);
});
ws.on('open', function() {
    ws.send('155-questions-active');
    ws.send('1-questions-active');
});

我很高兴知道 Java

中有一个可用的 websocket 客户端

好吧，我尝试使用您的代码来重现问题，但无济于事（获取证书，使用 keytool 命令导入它，然后运行代码）。我的输出是这样的。

所以我想如果你想要 java 中的运行ning 网络套接字客户端，我想你可以接受所有证书，比如@tinker 给你的 link .

代码应该是这样的。也许你可以尝试一下，看看你的地方会发生什么。

正确的方法是将您的客户端密钥库/信任库配置为信任您特定的自签名服务器证书。 Whosebug 上有很多答案，演示了如何通过简单地适当配置密钥库 and/or 信任库文件内容来使用 Java 执行此操作。（无需代码）。

如果你只想“连接”，而不关心信任、证书有效性，甚至端点标识验证（基本上是构成安全连接的所有好东西），那么你不需要不需要弄乱密钥库、信任库或自定义 X509TrustManagers 甚至自定义 SSLContexts 即可连接到服务。这种需求在 development/testing/qa 时期很常见，但不应在生产代码中使用。

如何使用 Jetty 9.4.35.v20201120 来配置 SslContextFactory.Client（属于 HttpClient，WebSocketClient 正在使用）信任所有证书。

import java.net.URI;
import java.util.concurrent.Future;

import org.eclipse.jetty.client.HttpClient;
import org.eclipse.jetty.util.log.Log;
import org.eclipse.jetty.util.log.Logger;

import org.eclipse.jetty.websocket.api.annotations.OnWebSocketError;
import org.eclipse.jetty.websocket.api.annotations.OnWebSocketMessage;
import org.eclipse.jetty.websocket.api.annotations.WebSocket;
import org.eclipse.jetty.websocket.client.WebSocketClient;

@WebSocket
public class SecureClientSocket
{
    private static final Logger LOG = Log.getLogger(SecureClientSocket.class);

    public static void main(String[] args)
    {
        String url = "wss://qa.sockets.stackexchange.com/";

        SslContextFactory.Client sslContextFactory = new SslContextFactory.Client();
        // Tell sslContextFactory to trust all server certificates
        // This is suitable for test/qa environments, and internal environments,
        // but IS NOT SUITABLE FOR PRODUCTION.
        // Note: this is not actually necessary for wss://qa.sockets.stackexchange.com/
        sslContextFactory.setTrustAll(true);
        // If you do choose to comment out the above, this option will cause the
        // Java client side SSL/TLS to validate the server certificate name
        // against the URL used to connect to the server, if it doesn't match
        // then the connection is not established.
        sslContextFactory.setEndpointIdentificationAlgorithm("HTTPS");

        HttpClient httpClient = new HttpClient(sslContextFactory);
        try
        {
            httpClient.start();
            WebSocketClient client = new WebSocketClient(httpClient);
            client.start();
            SecureClientSocket socket = new SecureClientSocket();
            Future<Session> fut = client.connect(socket, URI.create(url));
            Session session = fut.get();
            session.getRemote().sendString("Hello");
            session.getRemote().sendString("155-questions-active");
        }
        catch (Throwable t)
        {
            LOG.warn(t);
        }
    }

    @OnWebSocketConnect
    public void onConnect(Session sess)
    {
        LOG.info("onConnect({})", sess);
    }

    @OnWebSocketClose
    public void onClose(int statusCode, String reason)
    {
        LOG.info("onClose({}, {})", statusCode, reason);
    }

    @OnWebSocketError
    public void onError(Throwable cause)
    {
        LOG.warn(cause);
    }

    @OnWebSocketMessage
    public void onMessage(String msg)
    {
        LOG.info("onMessage() - {}", msg);
    }
}

这样的结果...

这是我的 Tyrus-java 客户端，它使用存根连接到我的 Jetty 9.3.6 服务器运行带有自签名证书的 HTTPS（改编自 Tyrus websocket client，第 8.1 节):

            client = ClientManager.createClient();

            //System.getProperties().put("javax.net.debug", "all"); // Useful for debugging SSL interaction
            // The keystore in the next two lines is the same keystore you used for running the server,
            // likely in ${jetty.base}/etc/keystore
            System.getProperties().put(SSLContextConfigurator.KEY_STORE_FILE, "/tmp/keystore");
            System.getProperties().put(SSLContextConfigurator.TRUST_STORE_FILE, "/tmp/keystore");
            // The following two passwords are what you used for your self-signed cert
            System.getProperties().put(SSLContextConfigurator.KEY_STORE_PASSWORD, "HumanReadablePassword");
            System.getProperties().put(SSLContextConfigurator.TRUST_STORE_PASSWORD, "HumanReadablePassword");
            final SSLContextConfigurator defaultConfig = new SSLContextConfigurator();

            defaultConfig.retrieve(System.getProperties());
            // or setup SSLContextConfigurator using its API.

            SSLEngineConfigurator sslEngineConfigurator = new SSLEngineConfigurator(defaultConfig, true, false, false);
            client.getProperties().put(GrizzlyEngine.SSL_ENGINE_CONFIGURATOR, sslEngineConfigurator);
            client.connectToServer(sillyWebSocketClient , ClientEndpointConfig.Builder.create().build(),
                                   new URI("wss://localhost:8443/sillyWebSocketServer/echo"));
            System.out.println ("Connected .... ");

其中 SillyWebSocketClient sillyWebSocketClient 扩展 javax.websocket.Endpoint。

我正在使用 Java 8/Gradle 2.7 环境，我的 build.gradle 看起来像这样：

apply plugin: 'java'

repositories {
    mavenCentral()
}

dependencies {
      compile 'javax:javaee-api:7.0'
      compile 'org.glassfish.grizzly:grizzly-core:2.3.23'
      compile 'org.glassfish.tyrus:tyrus-container-grizzly:1.2.1'
      compile 'org.glassfish.tyrus:tyrus-client:1.6'
      compile 'javax.websocket:javax.websocket-client-api:1.1'
}

希望对您有所帮助。
