xhr#U流媒体传输失败（Spring+；Zuul+；SockJS）

我得到了以下测试脚本（使用node执行，real client是浏览器，结果相同）：

const SockJS=require（'SockJS-client'）；
const webtomp=require（'webtomp-client'）；
让sock=newsockjs（/*在此处插入URL*/）；
让我们跺一下{
心跳：错，
});
connect（{}，function（）{
console.log（'connected'）；
}，函数（）{
console.log（'disconnected'）；
});

正在使用的版本：

• 弹簧防尘套-1.5.3
• SpringCloudNetflix-1.3.1
• Nginx-1.11
• RabbitMQ-3.6.9

为了排除我们的部分基础设施（如NGINX作为路由子域的代理等）是罪恶的根源，我尝试通过NGINX代理和Zuul直接连接到基于Spring的Stomp代理中继（使用RabbitMQ作为真正的代理）

前两个变体按预期工作，但第三个变体（使用Zuul作为带有ResourceServer注释的网关）失败。增加超时时间没有帮助，因为问题似乎在于“握手”。这是迄今为止我从客户端日志中得到的信息（前两个变体的日志，一切正常，甚至可以建立WebTomp）：

我希望任何人都有办法解决这个问题。似乎Zuul或其他东西没有返回sockjs响应。即使在服务器端使用跟踪也没有显示任何错误

网关本身是一个简单的设置，具有

@springbootcapplication

、

@EnableZuulProxy

、

@EnableResourceServer

和以下配置：

# increase the timeout of the proxy
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 60000
ribbon:
  ConnectTimeout: 3000
  ReadTimeout: 60000
zuul:
  host:
    connect-timeout-millis: 3000
    socket-timeout-millis: 60000
  # We don't want to automatically register all service available on Eureka
  ignored-services: "*"
  retryable: true
  # Default is "Cookie,Set-Cookie,Authorization", but we want to forward the Bearer Token
  sensitive-headers: Cookie,Set-Cookie
  routes:
    stomp:
      path: /stomp/**
      serviceId: stomp
      strip-prefix: true

我遇到了同样的问题。你解决这个问题了吗？我发现Zuul不支持长轮询（例如：websocket）。很抱歉，我不再从事此项目。似乎没有解决办法
