CookieLoginUtility

WebCTRL is a trademark of Automated Logic Corporation. Any other trademarks mentioned herein are the property of their respective owners.

This WebCTRL add-on allows scripts to bypass a limitation of headless chrome so that certain login cookies may be specified in query string parameters. The primary usage for this add-on is to automatically download and email a PDF of selected trend graphs. This requires some custom scripts and a scheduled task in addition to the add-on. Example scripts are provided below.

Usage

• If your server requires signed add-ons, copy the authenticating certificate ACES.cer to the ./programdata/addons directory of your WebCTRL installation folder.

• Install CookieLoginUtility.addon using the WebCTRL interface.

• Download the scripts from ./pdf-script to your computer, and place them in an empty folder.

• Setup and trend graph page and determine a direct link to it.

  • Navigate to the trend graph page.

  

  • Right-click on the trend graph title bar to the left of the gear, and hit the Inspect button.

  

  • Double-click on the src attribute on the iframe and copy the relative link.

  

  • Complete the relative link to get a full URL like: https://webctrl.something.net/_trendgraph/index.jsp?loc=%23aces_hw_system%2F~reports%2Fvfd_gpm_dp&bgcolor=%23D5D5D5&width=100%25&height=100%25
  • Naviagate to the completed URL to verify that it works.

• Edit your downloaded copy of main.ps1 to set the required parameters. The target parameter is the trend graph URL you found in the previous step. The url parameter is the root WebCTRL url (https://webctrl.something.net/). You'll also need to provide WebCTRL login credentials and some email server connection parameters.

• Start exec.bat to run the script. If it doesn't work, you may try uncommenting the REM pause line in exec.bat to see if any errors are shown before the command prompt closes.

  • Note that these scripts require an installation of Google Chrome and curl. Newer versions of Windows come with a default installation of curl, but it may need to be updated if you run into issues.

• You can schedule exec.bat in Windows task scheduler however you wish.
