WebSocket在此浏览器中连接另一个websocket

Question

I have my browser connecting to system hardware application at localhost using websocket. Sometimes this hardware application disabled, so I want to emulate this hardware application directly in the browser by creating another websocket. How can I do this?

I tried to emulate it by creating two websockets simultaneously, something like this:

socket1 = new WebSocket('ws://localhost:8080')
socket2 = new WebSocket('ws://localhost:8080')

But this doesn't work. How can I establish this connection?

Answer 1

I'd suggest using a mocking framework to mock the server in this situation. I have succesfully used mock-socket to do exactly this, eg. (quoting example from README.md):

var mockServer = new MockServer('ws://localhost:8080');
mockServer.on('connection', function(server) {
    server.on('message', function(data) {
        server.send('hello world!');
    } );
} );

Hope that helps.

Cheers,
