Proof of concept Shell as a Service (ShaaS). Exposes execution of PowerShell commands and scripts via REST methods. Can easily be extended to any shell (planned in future releases).

###Request Contexts

• /command/ - Executes named PowerShell command.
• /scripts/ - Executes named script.
• /exit/ - Terminates the service instance.

###Running Commands Commands are handled by the /command/ context. Most common commands are readily supported and will return any structured data in JSON format. Parameters are passed via url query parameters. Named values will be broken out into key/value pairs and added to the commandstring.

Run Get-Date command. http://127.0.0.1:8080/command/Get-Date

{
    "value":  "\/Date(1436237104231)\/",
    "DisplayHint":  2,
    "DateTime":  "Monday, July 6, 2015 9:45:04 PM"
}

Run Write-Host command. http://127.0.0.1:8080/command/Write-Host?"Hello,%20World!"

Hello, World!

                      "Exists":  true,
...
}

###Running Scripts Scripts are handled by the /scripts/ context. By default custom scripts are stored in the ./scripts/ directory relative to the service binary, but the location can be customized in the config.json. Much like the commands - parameters are passed via url query params. There is a simple test script included with the code that will allow the input of -Name. Adding/removing custom scripts requires no restarts nor recompiles.

Run script with no parameters (using defaults). http://127.0.0.1:8080/scripts/Hello-World

Hello, World!

Run script to greet 'Isaac'. http://127.0.0.1:8080/scripts/Hello-World?-Name=Isaac

Hello, Isaac!

###TODO

• Add Authentication
• Implement POST method of form values as parameters (takes precedence over query params)
• Command restrictions
• Additional configuration values
• Remote configuration
