如何从另一个节点服务器（在本地主机上）检查节点服务器中的 WebSocket 运行状态

Question

I have 2 node servers named server1 and server2 . From server1 I want to check whether websocket of server2 is running or not.

Answer 1

enable CORS in server2. you could create an html page to be rendered by server1, on the html page enable websocket, make sure the url of the websocket is pointing to server2, then use the send() method to send a message form the page to server2, on server2 listen for incoming message from websockets and respond appropriately back.. use send() and emit() methods respectively
