What kind of best way to send a image file to Node-RED

General

Hello there,

I want to save a image file from device to DB with Node-RED.
So i create flows as below inside Node-RED.

  1. create node 'http in'
  2. create node 'template'
  3. create node 'debug'

I am wondering how do i pick each value up from received form data.
I want to pick filename, form-data up.

[{"id":"da61568.38e3ea8","type":"template","z":"4fa5208f.bd0e1","name":"","field":"payload","fieldType":"msg","format":"handlebars","syntax":"mustache","template":"msg.req.headers : {{msg.req.files}}\nmsg.headers : {{msg.headers}}\nFile Name :  {{msg.req.headers.filename}}\nDATA_KEY : {{payload.filename}}\n*************************\n{{payload}}","output":"str","x":260,"y":300,"wires":[["d720d871.e20d08","5c5f2347.23f1bc"]]}]

[received data]
