Node Red Http In

Technical Preview

Overview

Client-mode REST API connectors for Node-RED and FlowFuse: read and deploy Node-RED flows through the Admin API, start and stop flows, read context, manage node modules, send MQTT data to your own HTTP In endpoints, and manage FlowFuse teams, applications, hosted instances, snapshots and devices from MQTT. This is one of the templates in the Node-RED (Admin API, HTTP In nodes) and FlowFuse REST API app (node-red-and-flowfuse). Deploy it alongside the other connectors of that app when they depend on each other (for example a token connector plus an API connector).

Auth

Auth headers used by the template: Authorization: Basic {value.json.basic}, Authorization: Bearer {value.json.token}.

Template parameters

Placeholder	Type	Description	Required
`RouteName`	string	Name of the Node Red Http In connector	no
`BaseUrl`	string	Node Red Http In base URL without trailing slash (e.g. http://YOUR_NODE_RED_HOST:1880)	yes

BASE_ADDRESS default: http://YOUR_NODE_RED_HOST:1880.

Deploy

Get the template card (JSON with template and metadata) from the broker, then deploy the connector:

mosquitto_pub -t '$SYS/Coreflux/Command' -m "-routeCode NODE_RED_HTTP_IN"

The deployable connector from the REST API app, with BASE_ADDRESS already filled in:

Usage example

Call HttpInPost by publishing a JSON payload to its request topic, and read the reply on the response topic:

mosquitto_sub -t 'historian/node-red-http/endpoint/post/response' &
mosquitto_pub -t 'historian/node-red-http/endpoint/post' -m '{"body": {}, "path": "<path>"}'
