WebSocket 握手期间的 Socket.io 代码 200 错误

Question

我正在将 socket.io 与 nodejs 和 apache 服务器一起使用。我收到代码 200 作为响应，我知道我必须得到 101。

WebSocket connection to 'wss://SITEABC.com/socket.io/?siteId=site1234567&EIO=3&transport=websocket' failed: Error during WebSocket handshake: Invalid status line

apache 上的配置如下:

RewriteCond %{HTTP:Upgrade} ^Websocket [NC]
RewriteCond %{HTTP:CONNECTION} ^Upgrade$ [NC]
RewriteRule .* ws://localhost:1337/{REQUEST_URI} [P]

RewriteCond %{REQUEST_METHOD} OPTIONS
RewriteRule ^(.*)$ $1 [R=200,L]

ProxyPass / http://localhost:1337/
ProxyPassReverse / http://localhost:1337/
ProxyPass /socket.io/ http://localhost:1337/socket.io/

节点在 1337 端口上运行

Answer 1

我用的是springboot 2 + stomp。就我而言，原因在 WebSocketConfig 中，必须删除 .withSockJS。

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/ws").setAllowedOrigins("*")
                .addInterceptors(new HandshakeInterceptor())

                //--> important must remove,or 200 error.
                //.withSockJS()

                ;
    }
