url

Summary

The absolute URL as resolved by the constructor.

Note: This property is read-only.

var result = element.url;

Returns an object of type StringString

The URL specifies the following details about the connection.

Scheme ― The scheme must be “ws” or "wss". The “ws” scheme is insecure, while “wss” indicates a secure connection. Pages that are served over HTTP should use “ws” WebSockets, while HTTPS pages should use "wss". Attempting to use a scheme other than “ws” or “wss” throws an error.
Host ― The host is the name or IP address of the server.
Port ― This specifies the remote port to connect to. If the port is not specified then a default is selected based on the scheme. “ws” connections default to port 80, while “wss” connections default to 443.
Resource Name ― The resource name is the path component of the URL which follows the host/port. This includes the URL query component (the part following a question mark), if one is present. The resource name can be omitted, in which case it defaults to a forward slash "/".

Example URLs

scheme://host:port/resource
ws://localhost:8080/echo
wss://cjihrig.com

You can use this property to make sure that the URL that is used for the connection is parsed the way the app expects.
