Question

我有一个客户端Angular 2应用程序和一个Spring启动（1.4.1.RELEASE）服务器应用程序。我编写了客户端代码，使用角度库ng2-stomp-service向服务器发送连接请求，并使用服务器代码来管理连接请求。

使用http时一切正常，但使用https时，我在javascript控制台中看到连接错误（HTTP / 1.1 400）：

GET https://tomcatunisvid.lunagest.com/unisvid/workflow/046/mmesis4u/websocket [HTTP/1.1 400  358ms]

Firefox non può stabilire una connessione con il server wss://tomcatunisvid.lunagest.com/unisvid/workflow/046/mmesis4u/websocket.

在Firefox中，我找到了请求和响应标头：

- 请求标题

并且响应为空。

以下是我的相关客户代码：

// In the constructor, where stomp is a StompService:

stomp.configure({
  host: this.url,
  debug: true,
  queue: { 'init': false, '/user/queue/user/reply': false },
  // headers: { 'upgrade': 'WebSocket' }
});

// in another method:

this.stomp.startConnect().
  then(() => this.openSocket_OK_Callback(this)).
  catch((error) => this.openSocket_KO_Callback(this, error));

这是我的相关服务器代码：

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends 
AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.setApplicationDestinationPrefixes("/wfm");
        config.enableSimpleBroker("/topic", "/queue");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        SessionDisconnectionListener sdl = new SessionDisconnectionListener();

        String endpoint = "/workflow";

        registry.addEndpoint(endpoint).
            setAllowedOrigins("*").withSockJS();

        registry.addEndpoint(endpoint).setHandshakeHandler(new DefaultHandshakeHandler(new TomcatRequestUpgradeStrategy())).
            setAllowedOrigins("*").withSockJS();

    }

}

有任何提示如何解决这个问题？

我把调试后找到的答案放在这里，以防其他人有用。在发布环境中，Tomcat由Apache Http Server代理。这种情况下的解决方案是删除Apache Http Server并直接在Tomcat上配置Https。

ng2-stomp-service无法连接到https中的Spring服务器
