连接到websocket时我得到状态200，但这是一个错误？ [英] I get a status 200 when connecting to the websocket, but it is an error?
问题描述
我的错误显示在浏览器的控制台中：
My error shows up in the console of my browser:
WebSocket连接到'ws：// localhost：32768 / DspClusterWebServices / myHandler'失败：意外的响应代码：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：
I am using Spring Websockets 4.1.5 and Tomcat 8.0.18. My WebSocketConfigurer implementation class looks like:
@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尝试连接此代码，但错误代码为200：
My testWebsocketClient.js tries to connect with this code, but has a error code of 200:
websocket = new WebSocket("ws://localhost:8080/myApp/myHandler");
我无法弄清楚下一步该尝试什么。我以为这会导致afterConnectionEstablished（WebSocketSession会话）方法被触发？代码200不好吗？
I cannot figure out what to try next. I thought that this would cause the afterConnectionEstablished(WebSocketSession session) method to fire? Isn't code 200 good?
推荐答案
请检查 http://procbits.com/connecting-to-a-sockjs-server-from-native-html5-websocket ！
在您附加 / websocket （到您的网址）后，它会给您错误
After you append /websocket (to your URL), it will give you the error
无法解析Origin标头值[null]
Failed to parse Origin header value [null]
;）
，然后将引导您该链接。
您必须将 .setAllowedOrigins（*）添加到 addHandler（）方法，然后它终于可以工作了！
You'll have to add .setAllowedOrigins("*") to your addHandler() method, and then it could finally work!
