Python 用于芹菜任务监控和发布到React应用程序的WAMP组件

我有一个React应用程序，通过Klein发布并异步运行芹菜作业（通过RabbitMQ）。我希望通过WAMP发布/订阅（我使用Crossbar作为路由器）在一些表中显示状态更新的所有任务。My React table组件获取初始数据并订阅如下更改：

class Table extends React.Component {
  componentWillMount(){
    this.props.session //Autobahn session variable passed down as prop
      .subscribe("celery.update.task", (args,kwargs,details)=>{update state})
  }
  componentDidMount(){
    //Gets all tasks in db (SQLite)
    this.props.session.call("celery.all.tasks", (a,k,d)=>{set initial state}
  }
  render() {
    //render table with data from state
  }

我目前正在尝试让后端的WAMP组件（使用AutobahnPython）在芹菜事件上发布“celery.update.task”。这个应用程序将面向internet，所以我想使用安全websockets（wss）并遵循运行WAMP组件的教程。我当前的问题是，WAMP组件并不异步发布（一旦python进程结束，所有发布都会被发送）：

上面的代码能够监视所有事件，但在python进程结束之前，不会将发布方法推送到订阅者。我希望WAMP组件在每个芹菜事件（接收、启动、成功、失败）上发布到“celery.task.update”，以便实时更新表组件

有没有办法让这一切顺利进行？我试过了，但没有成功。我试了又试
