WebSocket SyntaxError: An invalid or illegal string was specified

rated 0 times [ 35] [ 6] / answers: 1 / hits: 23020 / 9 Years ago, fri, january 15, 2016, 12:00:00

I'm getting a SyntaxError: An invalid or illegal string was specified, while trying to connect to a WebSocket on Firefox.

<!doctype html>

<html>

  <head><meta charset=utf-8></head>

  <body>

    <script>

    var socket = new WebSocket('127.0.0.1:1234');

    </script>

  </body>

</html>

Why do I get this error?

It seems like the scheme is mandatory when trying to connect to a WebSocket, so this:

var socket = new WebSocket('ws://127.0.0.1:1234');

works just fine (or as @RaulNoheaGoodness pointed out in the comments, wss:// when using WebSocket over TLS).
