【问题描述】：

我已经解决了这个问题，这段代码帮助我自动检测服务器是 https 还是 http。然后 Javascript 只需创建正确的链接 SockJS 以订阅服务器 Web-socket。

代码如下：

var protocol = location.protocol;
var hostname = location.hostname;
var port = location.port;
var url_prefix = protocol + "//" + hostname + (port === '' ? '' : ':' + port) + contextPath;
var sock = new SockJS(url_prefix + '/connectsocket');

Spring websocket 在 localhost 上运行正常：

var socket = new SockJS('http: //localhost:9091/connect/sockjs');

bics.cfapps.io 上的 Spring websocket 运行错误：

var socket = new SockJS('http: //bics.cfapps.io/connect/sockjs');

错误信息 console.log：

WebSocket connection to 'ws://bics.cfapps.io/connect/sockjs/376/7o5_41y7/websocket' failed: Error during WebSocket handshake: Unexpected response code: 400

sockjs-0.3.4.js:807 POST http: //bics.cfapps.io/connect/sockjs/376/colrrwci/xhr_streaming 500 (Internal Server Error)

Whoops! Lost connection to undefined

添加端口 4443 但在 bics.cfapps.io 上仍然报错：

var socket = new SockJS('http: //bics.cfapps.io:4443/connect/sockjs');

错误信息 console.log：

XMLHttpRequest cannot load http: //bics.cfapps.io:4443/connect/sockjs/info. No 'Access-Control-Allow-Origin' header is present on the requested resource.

Origin 'http: //bics.cfapps.io' is therefore not allowed access. The response had HTTP status code 408.

Whoops! Lost connection to undefined

添加端口 4443 & ws 但在 bics.cfapps.io 上仍然报错：

var socket = new WebSocket('ws://bics.cfapps.io:4443/connect/sockjs');

错误信息 console.log：

WebSocket connection to 'ws://bics.cfapps.io:4443/connect/sockjs' failed: Error during WebSocket handshake: Unexpected response code: 408

Whoops! Lost connection to ws://bics.cfapps.io:4443/connect/sockjs

我的代码配置：

@Configuration
@EnableWebSocket
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/topic");
        config.setApplicationDestinationPrefixes("/bics");
    }
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/connect/sockjs").withSockJS();
    }
}

【问题讨论】：

请发布您的 websocket 配置和日志。是否从同一来源建立连接？
@ThanhNguyenVan 请查看我的更新问题。我的项目在我的本地运行正常，但在 cloudfoundry 上运行错误......如上所述的错误
我也遇到了同样的问题，你有什么发现吗
阅读这个？ docs.run.pivotal.io/release-notes?你需要 wss: 而不是 ws:

【解决方案1】：

只是指出 gregturn 在 cmets 中给出的答案是正确的：

PWS 确实不通过ws: 支持普通 websocket，但仅通过wss: 支持安全 websocket。此外，它们在非标准端口 4443 上工作。

见PWS release notes June 2016
