@hapi/nes websocket 客户端用于 angular

如何解决@hapi/nes websocket 客户端用于 angular

我有一个@hapi/nes websocket 服务器。我的测试 nes 客户端运行良好。

const nes = require('@hapi/nes');
const client = new nes.Client('localwebsocket/9000');
const start = async () => {
     await client.connect();
     const handler = (message) => {
          console.log('message: ',message);
     };
     client.subscribe('/messageEndpoint',handler);
};

在我的前端/客户端 angular 10 中，我尝试使用 rxjs/webSocket

constructor(){
    subject = webSocket('ws://localwebsocket/9000/messageEndpoint');
    this.socket.subscribe(
      msg => console.log('socket message received: ' + JSON.stringify(msg)),// Called whenever there is a message from the server.
      err => console.log('socket: ',err),// Called if at any point WebSocket API signals some kind of error.
      () => console.log('socket closed') // Called when connection is closed (for whatever reason).
    );
}

我的前端代码不起作用，因为总是断开连接并且没有保持活动状态以等待消息。
