握手時出錯403

瀏覽器控制臺錯誤提示

Error during WebSocket handshake: Unexpected response code: 403

配置示例

• websocket 注冊

@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
    registry.addHandler(socketHandler, "/test").addInterceptors(new SystemInfoSocketHandshakeInterceptor());
    registry.addHandler(socketHandler, "/sockjs/test").addInterceptors(new SystemInfoSocketHandshakeInterceptor())
            .withSockJS();
}

• 握手?jǐn)r截器

@Configuration
public class SystemInfoSocketHandshakeInterceptor implements HandshakeInterceptor {

    @Override
    public boolean beforeHandshake(ServerHttpRequest request, ServerHttpResponse response, WebSocketHandler wsHandler, Map<String, Object
            > attributes) {
        log.info("socket beforeHandshake..");
        if (request instanceof ServletServerHttpRequest) {
            ServletServerHttpRequest servletRequest = (ServletServerHttpRequest) request;
            HttpSession session = servletRequest.getServletRequest().getSession(false);
            // 業(yè)務(wù)處理
        }
        return true;
    }

    @Override
    public void afterHandshake(ServerHttpRequest request, ServerHttpResponse response, WebSocketHandler wsHandler, Exception exception) {
        log.info("socket beforeHandshake..");
    }
}

• 客戶端連接

var wsServer = "ws://127.0.0.1:8080";
var webSocket;
if ('WebSocket' in window || 'MozWebSocket' in window) {
    webSocket = new WebSocket(wsServer + "/test");
} else {
    webSocket = new SockJS(wsServer + "/sockjs/test");
}

webSocket.onerror = function (event) {
    console.log("websockt連接錯誤")
};

分析

• 連接失敗
• 訪問攔截
• nginx代理
• 跨域

解決

連接問題

如果是連接上面的問題，一般看一下配置是否正確

注意版本問題

訪問攔截

在攔截器中，解除攔截

@Bean
public WebMvcConfigurer corsConfigurer() {
    return new WebMvcConfigurer() {
        @Override
        public void addCorsMappings(CorsRegistry registry) {
            registry.addMapping("/**").allowedOrigins("*");
        }
    };
}

nginx代理

在nginx中配置
proxy_set_header Upgrade $http_upgrade
proxy_set_header Connection "upgrade"
proxy_set_header Host $host
三個配置

完整配置如下:

location / {
    proxy_pass http://127.0.0.1:8080;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $host;
    proxy_http_version 1.1;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

跨域

添加setAllowedOrigins("*")解決跨域問題

@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
    registry.addHandler(socketHandler, "/test")
            .addInterceptors(new SystemInfoSocketHandshakeInterceptor())
            .setAllowedOrigins("*");
    registry.addHandler(socketHandler, "/sockjs/test")
            .addInterceptors(new SystemInfoSocketHandshakeInterceptor())
            .setAllowedOrigins("*")
            .withSockJS();
}
