在将基于REACT的WebSocket客户端连接到基于
Java Jetty的Web Socket服务器时,我收到以下错误 –
WebSocket connection to 'ws://localhost:2319/ws' failed: Error during WebSocket handshake: Unexpected response code: 302
通过Chrome的Smart Web Socket客户端连接时,此错误不存在.
我正在尝试基于REACT开发Web Socket客户端.客户代码是 –
var connection = new WebSocket('ws://localhost:2319/ws');
connection.onopen = function () {
// connection is opened and ready to use
};
WebSocket Server一直基于Jetty.服务器代码是 –
server = new Server();
ServerConnector connector = new ServerConnector(server);
connector.setPort(SSConstants.WWBSOCKET_PORT);
server.addConnector(connector);
// Setup the basic application "context" for this application at "/"
// This is also known as the handler tree (in jetty speak)
ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/ws"); // Set to "/ws" for future integration with the main jetty server.
server.setHandler(context);
try {
// Initialize javax.websocket layer
ServerContainer wsContainer = WebSocketServerContainerInitializer.configureContext(context);
// Add WebSocket endpoint to javax.websocket layer
wsContainer.addEndpoint(WebsocketListener.class);
server.start();
}
catch (Throwable t) {
ssLogger.logInfo("Websocket Server start exp : ");
t.printStackTrace(System.err);
}
输出 –
WebSocket connection to 'ws://localhost:2319/ws' failed: Error during WebSocket handshake: Unexpected response code: 302
Request URL:ws://localhost:2319/ws
