Ouija

Server software for proxying HTTP requests through PhantomJS. It'll make your automated requests look more human!

Requirements

PhantomJS must be installed and available in the PATH.

Installation

$ npm install ouija

Usage

ouija [options]

At its most basic, start the server by running:

$ ./ouija

Options

  • -h, --help: Display usage information.

  • -V, --version: Display the version number.

  • -p, --port <n>: The port to bind the proxy server to, defaults to 6660.

    Example:

    $ ./ouija -p 8080
    

    ...binds Ouija to port 8080.

  • -l, --log-level <level>: Set how noisy the log output is. Accepted values are SILENT, ERROR, WARN, or DEBUG; defaults to ERROR.

    Example:

    $ ./ouija -l DEBUG
    

    ...sets the logging output to DEBUG.

  • -b, --blacklist <file>: Specify a host blacklist configuration file, preventing the loading of assets from specific hosts. The blacklist configuration file should be well formatted JSON; a single key blacklist referencing an array of host strings.

    Example:

    $ cat blacklist.json
    {
        "blacklist": [
            "example.com",
            "bar.com"
        ]
    }
    $ ./ouija -b blacklist.json
    

    ...would prevent the loading of assets from the following hosts:

    • example.com
    • *.example.com
    • bar.com
    • *.bar.com
  • -s, --storage-path <path>: Set the path used by PhantomJS for local storage and client-side SQLite databases; defaults to $HOMEDIR/.ouija/localstorage. If the supplied directory doesn't exist, it will be created.

    Example:

    $ ./ouija -s /tmp/ouija
    

    ...would change the directory PhantomJS uses to store local data to /tmp/ouija.

Once the server is up and running, simply issue requests to it like you would to any other proxy server. This means providing the host when requesting the resource, e.g.:

GET http://example.com/foo/bar.html

...instead of:

GET /foo/bar.html

Special HTTP Headers

Request Headers

Ouija accepts some special HTTP headers for manipulating the response or configuring the resulting request. As usual, the header names are case-insensitive.

  • Ouija-Get-Unmodified-Content: Normally, if scripts on the page modify the DOM of the requested page, Ouija will return the modified source. Passing this header will ensure you recieve the unmodified source. The value of the header is inconsequential; Ouija only checks for its presence.

  • Ouija-Follow-HTTP-Redirect: Normally, Ouija will return the HTTP redirect response and not the resource specified by the redirect. By passing this header, Ouija will follow the HTTP redirect and return the response received by requesting the resource referenced by the redirect.

  • Ouija-Proxy: Specify a proxy server to use (e.g. 10.10.10.10:8080).

  • Ouija-Proxy-Type: Set the type of proxy server (one of http, socks5 or none; defaults to http).

  • Ouija-Proxy-Auth: Authentication information for the proxy server (e.g. username:password).

  • Ouija-Wait: Delay the capture of the URL contents by the provided number of milliseconds (e.g. 2000).

  • Ouija-Local-Storage-Id: Set the local storage ID, allowing local storage and client-side SQLite databases to be shared across/isolated to specific requests.

  • Ouija-Pass-*: Any headers prefixed with Ouija-Pass- will be used in the resulting request (with Ouija-Pass- stripped from the name). E.g., passing:

    Ouija-Pass-User-Agent: Ouijabot

    ...will result in the following header in the resulting request:

    User-Agent: Ouijabot

Response Headers

If the requested page has any JavaScript errors, the error message will be returned as the value of the Ouija-JS-Error header.
