连接到Websocket时状态为200,但这是错误的吗?
我的错误显示在浏览器的控制台中:
"WebSocket connection to
'ws://localhost:32768/DspClusterWebServices/myHandler' failed: Unexpected
response code: 200"
我正在使用Spring Websockets 4.1.5
和Tomcat 8.0.18
。我的WebSocketConfigurer实现类如下所示:
@Configuration@Controller
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer
{
class MyHandler implements WebSocketHandler
{
@Override
public void afterConnectionEstablished(WebSocketSession session) throws Exception
{
System.out.println("afterConntectionEstablished called");
}
...implements rest of functions with a System.out.println and false for supportsPartialMessages()
}
}
@Override registerWebSocketHandlers(WebSocketHandlerRegistry registry)
{
registry.addHandler(myHandler(), "myHandler").withSockJS();
}
@Bean
public WebSocketHandler myHandler()
{
return new MyHandler();
}
}
我的testWebsocketClient.js尝试与此代码连接,但错误代码为200:
websocket = new WebSocket("ws://localhost:8080/myApp/myHandler");
我不知道下一步该怎么做。我以为这会导致afterConnectionFounded(WebSocketSession
session)方法启动?代码200不好吗?

请检查http://procbits.com/connecting-to-a-sockjs-server-from-native-

附加/websocket
(到您的URL)后,它将给您错误
无法解析Origin标头值[null]
;),然后依次将您带到该链接。
您必须添加.setAllowedOrigins("*")
到您的addHandler()
方法中,然后它才可以正常工作!
