Convert http posts to mqtt events

post2mqtt

A easy help to convert http posts to mqtt events. This is how it works.

• The system listens to post events.
• The url in the post is used as the mqtt-topic.
• The bodu in the post is used as the mqtt-message

Usages

I use this in my home assistant automation. Especially for webhooks from iftt. This saves me from giving out the home assistant api token and also I get to use mqtt

Configuration variables

Environment variables:

Name	Descripttion	Default value
PORT	The port to listen on for the http requests	8080
MQTT_URL	The url to the mqtt server	mqtt://localhost
MQTT_USERNAME	Username for the MQTT server	''
MQTT_PASSWORD	Password for the MQTT	''
MQTT_RETAIN	MQTT retain flag for messages. Valid values are true, false.	false
TOKEN	Token that caller should use to authenticate with	''

Examples

From source

The server is started with TOKEN=theauthtoken yarn start then

curl -d '{"key1":"value1", "key2":"value2"}' \
 -H "Content-Type: application/json" \
 -H "Authorization: theauthtoken" \
 -X POST http://localhost:8080/a/b

Whould post

{ "key1": "value1", "key2": "value2" }

to the a/b mqtt topic to the localhost mqtt

If you cant use Authorization header thefollowing does the same thing

curl -d '{"key1":"value1", "key2":"value2"}' \
 -H "Content-Type: application/json" \
 -X POST http://localhost:8080/a/b?token=theauthtoken

Docker

The server can be started from docker

docker run --rm -e TOKEN=theauthtoken \
           -e MQTT_URL="mqtt://192.168.0.3" \
           -p 8080:8080 mtand/post2mqtt
