Question

我使用jetty 9.2.5创建了一个简单的嵌入式WebSocket服务器。使用不安全的连接时，服务器可以正常运行。当我添加SSL连接器时，客户端无法使用https方案连接，＆＃34; wss＆＃34; vs＆＃34; ws＆＃34;，我看到一个badMessage警告：

31710 [qtp6566818-16] WARN  org.eclipse.jetty.http.HttpParser  - badMessage: 400 Illegal character 0x16 in state=START in '\x16<<<\x03\x01\x00\xAb\x01\x00\x00\xA7\x03\x037%\x03d\xFf\xBd\xE8...\x01\x05\x01\x02\x01\x04\x03\x05\x03\x02\x03\x04\x02\x02\x02>>>\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00...\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00' for HttpChannelOverHttp@f59306{r=0,c=false,a=IDLE,uri=-}

当我将URI恢复为不安全的WebSocket方案时，客户端没有问题：

40562 [qtp6566818-17] INFO  com.datafascia.emerge.websocketEchoService.EchoService  - Session: WebSocketSession[websocket=JettyAnnotatedEventDriver[com.datafascia.emerge.websocketEchoService.EchoService@18c45017],behavior=SERVER,connection=WebSocketServerConnection@77882dcc{IDLE}{f=Flusher[queueSize=0,aggregateSize=0,failure=null],g=Generator[SERVER,validating],p=Parser@61ed4bc3[ExtensionStack,s=START,c=0,len=0,f=null,p=WebSocketPolicy@379e5d9e[behavior=SERVER,maxTextMessageSize=65536,maxTextMessageBufferSize=32768,maxBinaryMessageSize=65536,maxBinaryMessageBufferSize=32768,asyncWriteTimeout=60000,idleTimeout=300000,inputBufferSize=4096]]},remote=WebSocketRemoteEndpoint@2e93a9a8[batching=true],incoming=JettyAnnotatedEventDriver[com.datafascia.emerge.websocketEchoService.EchoService@18c45017],outgoing=ExtensionStack[queueSize=0,extensions=[],incoming=org.eclipse.jetty.websocket.common.WebSocketSession,outgoing=org.eclipse.jetty.websocket.server.WebSocketServerConnection]]

服务器的代码几乎取自我在jetty网站和互联网上遇到的例子。以下是设置WebSocket servlet的代码：

// Setup the websocket server
Server server = new Server(websocketPort);

if (wssEnabled) {
  // Add http/s connectors
  //connector = new ServerConnector(server);
  //connector.setPort(websocketPort);

  // HTTP Configuration
  HttpConfiguration http_config = new HttpConfiguration();
  http_config.setSecureScheme("https");
  http_config.setSecurePort(8443);
  http_config.setOutputBufferSize(32768);
  http_config.setRequestHeaderSize(8192);
  http_config.setResponseHeaderSize(8192);
  http_config.setSendServerVersion(true);
  http_config.setSendDateHeader(false);

  SslContextFactory sslContextFactory = new SslContextFactory();
  sslContextFactory.setKeyStorePath("/home/jedwards/keystore");
  logger.info("keystore path: {}", sslContextFactory.getKeyStorePath());
  sslContextFactory.setKeyStorePassword("1deadparrot");
  sslContextFactory.setKeyManagerPassword("1deadparrot");
  sslContextFactory.setExcludeCipherSuites(
      "SSL_RSA_WITH_DES_CBC_SHA","SSL_DHE_RSA_WITH_DES_CBC_SHA","SSL_DHE_DSS_WITH_DES_CBC_SHA",
      "SSL_RSA_EXPORT_WITH_RC4_40_MD5","SSL_RSA_EXPORT_WITH_DES40_CBC_SHA","SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA",
      "SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA");

  // SSL HTTP Configuration
  HttpConfiguration https_config = new HttpConfiguration(http_config);
  https_config.addCustomizer(new SecureRequestCustomizer());

  // SSL Connector
  connector = new ServerConnector(server,
      new SslConnectionFactory(sslContextFactory,HttpVersion.HTTP_1_1.asString()),
      new HttpConnectionFactory(https_config));
  connector.setPort(8443);
  connector.setIdleTimeout(500000);
} else {
  // Basic HTTP connector
  connector = new ServerConnector(server);
  connector.setPort(websocketPort);
}
ServletContextHandler ctx = new ServletContextHandler();
ctx.setContextPath("/");
ctx.addServlet(EmergeEchoServiceSocketServlet.class, websocketServicePoint);

server.setHandler(ctx);
server.addConnector(connector);

// Start the websocket server
server.start();
logger.info("server status: {}", server.dump());
server.join();

我使用推荐的命令创建了自签名证书和密钥对：

keytool -keystore keystore -alias jetty -genkey -keyalg RSA

此时我感到很茫然，因为我相信我已经正确设置了嵌入式WebSocket servlet。所以我认为它显而易见，但我无法弄清楚问题。

Answer 1

我稍微简化了代码，并且能够使SSL WebSockets服务器正常工作。我还在使用自签名证书，所以它只是本地证书。我可以使用IP地址，但不能使用＆＃34; localhost＆＃34;例如＆＃34; WSS：//192.168.2.115：8443 /服务点＆＃34 ;.

这是新代码：

// Setup the websocket server
Server server = new Server();

if (wssEnabled) {
  // HTTP Configuration
  HttpConfiguration https_config = new HttpConfiguration();
  https_config.setSecureScheme("https");
  https_config.setSecurePort(8443);
  https_config.setSendServerVersion(true);
  https_config.setSendDateHeader(false);
  https_config.addCustomizer(new SecureRequestCustomizer());

  SslContextFactory sslContextFactory = new SslContextFactory();
  sslContextFactory.setKeyStorePath("/pathTo//keystore");
  sslContextFactory.setTrustStorePath("/pathTo/keystore");
  logger.info("keystore path: {}", sslContextFactory.getKeyStorePath());
  sslContextFactory.setKeyStorePassword("myPassword");
  sslContextFactory.setKeyManagerPassword("myPassword");
  sslContextFactory.setTrustStorePassword("myPassword");
  sslContextFactory.setExcludeCipherSuites(
      "SSL_RSA_WITH_DES_CBC_SHA",
      "SSL_DHE_RSA_WITH_DES_CBC_SHA",
      "SSL_DHE_DSS_WITH_DES_CBC_SHA",
      "SSL_RSA_EXPORT_WITH_RC4_40_MD5",
      "SSL_RSA_EXPORT_WITH_DES40_CBC_SHA",
      "SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA",
      "SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA");

  // SSL Connector
  connector = new ServerConnector(server,
      new SslConnectionFactory(sslContextFactory,HttpVersion.HTTP_1_1.asString()),
      new HttpConnectionFactory(https_config));
  connector.setPort(8443);
} else {
  // Basic HTTP connector
  connector = new ServerConnector(server);
  connector.setPort(websocketPort);
}

ServletContextHandler ctx = new ServletContextHandler();
ctx.setContextPath("/");
ctx.addServlet(EmergeEchoServiceSocketServlet.class, "/dF" + websocketServicePoint);

server.setHandler(ctx);
server.addConnector(connector);

// Start the websocket server
server.start();
logger.info("server status: {}", server.dump());
server.join();

}
