我正在测试使用javascript websocket连接的聊天服务应用程序(javascript和java)。在我自己的机器上一切正常。我在Google计算引擎(GCE)实例上部署了该应用程序。当我尝试使用聊天服务时,连接失败(错误代码:1006)。我将在下面发布相关代码
websocket连接的javascript代码是
var server;
try {
server = new WebSocket('ws://' + window.location.host +
'<c:url value="/chat/${chatSessionId}" />');
server.binaryType = 'arraybuffer';
} catch(error) {
modalErrorBody.text(error);
modalError.modal('show');
return;
}
server.onerror = function(event) {
modalErrorBody.text(event.data);
modalError.modal('show');
};
我尝试了以下替代方案
server = new WebSocket('ws://***.***.**.*' + '<c:url value="/chat/${chatSessionId}" />');
server = new WebSocket('ws://***.***.**.*:80' + '<c:url value="/chat/${chatSessionId}" />');
这些都不起作用。相同的错误消息(错误代码:1006)
以下是代码的java部分:
@ServerEndpoint(value = "/chat/{sessionId}",
encoders = ChatMessageCodec.class,
decoders = ChatMessageCodec.class,
configurator = ChatEndpoint.EndpointConfigurator.class)
@WebListener
public class ChatEndpoint implements HttpSessionListener
{
private static final String HTTP_SESSION_PROPERTY = "com.wrox.ws.HTTP_SESSION";
private static final String WS_SESSION_PROPERTY = "com.wrox.http.WS_SESSION";
private static long sessionIdSequence = 1L;
private static final Object sessionIdSequenceLock = new Object();
private static final Map<Long, ChatSession> chatSessions = new Hashtable<>();
private static final Map<Session, ChatSession> sessions = new Hashtable<>();
private static final Map<Session, HttpSession> httpSessions =
new Hashtable<>();
public static final List<ChatSession> pendingSessions = new ArrayList<>();
@OnOpen
public void onOpen(Session session, @PathParam("sessionId") long sessionId)
{
...
}
@OnMessage
...
@OnClose
...
}
答案 0 :(得分:0)
我发现在tomcat的server.xml中,以下部分被注释掉,导致问题
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
