There are multiple ways to handle inter-process communication between PhantomJS and other processes.

File I/O

• files

HTTP

• outgoing HTTP requests (to other processes/services)

  • GET/POST data to a server endpoint
  • GET/POST data to a server endpoint, parse resulting JSON/XML/HTML/etc.
  • Create a XMLHttpRequest object and use it as you would in a normal web page
  • Cross-domain requests are restricted by default (PhantomJS code is considered to be in file:// scope). Use Access-Control-Allow-Origin on your server to enable access.

• incoming HTTP requests (server). Use the WebServer module

• route PhantomJS traffic through an HTTPS proxy like mitmproxy/libmprox or fiddler

Websockets inside a WebPage context

• hixie-76 websockets only
• PhantomJS 2.x will eventually get a WebKit upgrade that has RFC 6455 websockets.

stdin, stdout, and stderr

See the stdin-stdout-stderr.js example script for details.
