NAME

perl-SMS-Send-Adapter-Node-Red.psgi - SMS::Send Adapter to Node-RED JSON HTTP request PSGI Script

DESCRIPTION

A PSGI application to control SMS::Send with a web service.

API

The script is called over HTTP with a JSON Object payload.

POST http://127.0.0.1:5000/

{
 "driver"  : "VoIP::MS",
 "to"      : "7035551212",
 "text"    : "Text Message",
 "options" : { "this" : "or", "that" : "and" }
}

There are many SMS::Send drivers available on CPAN. I use VoIP::MS in examples since that is the provider that I use for my home automation notifications. My other notiable drivers are Kannel::SMSbox and NANP::Twilio.

Return is a JSON Object.

200 OK

{
 "sent"  : true,
 "input" : {...},
}

Return on error.

400|500|502 ...

{
  "sent": false,
  "input": {...},
  "error": "error string to help point you in the correct direction"
}

Node-Red Integration

Use four nodes: inject, function, http request, and debug.

  • In the function node

    • Set the "payload" to a JSON Object with the keys "driver", "to" and "text" and any extra "options" needed for SMS::Send objects not built on SMS::Send::Driver::WebService.

      my_text     = msg.payload;
msg.payload = {
               "driver"  : "VoIP::MS",
               "text"    : my_text,
               "to"      : "7035551212",
               "options" : {"key" : "value"},
              };
return msg;

  • In the http request node

    • Set the "Method" to POST

    • Set the "URL" to http://127.0.0.1:5000/

    • Set the "Return" to a parsed JSON Object

  • In the debug node

    • Set the "Output" to msg.payload.sent which returns boolean true or false
