dataurltopng

dmachat/dataurltopng

dataurltopng provides a service to convert base64 encoded png strings from html5 dataurl attributes into real png files

Installation

Create an upstart task for the server:

# Upstart Configuration

description     "Dataurl to PNG service"

start on (net-device-up
          and local-filesystems
          and runlevel [2345])

stop on runlevel [016]

respawn

exec /usr/local/go/bin/dataurltopng 

Usage

Compile the binary and run on your server, optionally using a Config.gcfg file to overwrite basic auth and image path values.

POST requests should look like

{
  Sitename: "sitename",
  Dataurl: "data:image/png;base64,..."
}

Configuration

You can add a go config file -- Config.gcfg -- in the directory with the go binary to set environment variables like port, authentication information and images directory:

[server]
port = "9000"
imagedir = "/usr/local/images"
username = "data"
password = "topng"

You'll get back a json object with a success and filepath property.
