convert upc to gtin

gtin

REST API to Convert UPC number to valid GTINs ("Global Trade Item Numbers"). Can specify length in JSON request. Default to GTIN 12.

Usage

sudo docker-compose up --build

Make sure to use host="0.0.0.0" in app.py when using Docker, otherwise seems not working.

Examples

Default is 12 digits:

$ curl -i -H "Content-Type: application/json" -X POST -d '{"upc":"7447010150"}' http://localhost:5000/gtin/api/v1.0/convert
HTTP/1.0 201 CREATED
Content-Type: application/json
Content-Length: 29
Server: Werkzeug/0.14.1 Python/3.6.4
Date: Wed, 27 Mar 2019 01:40:17 GMT

{
      "gtin": "074470101505"
          
}

However Can convert to any GTIN. You can specify the length in the payload. For example, for 14 digit GTIN.

$ curl -i -H "Content-Type: application/json" -X POST -d '{"upc":"7447010150", "length":14}' http://localhost:5000/gtin/api/v1.0/convert
HTTP/1.0 201 CREATED
Content-Type: application/json
Content-Length: 31
Server: Werkzeug/0.14.1 Python/3.6.4
Date: Wed, 27 Mar 2019 01:40:28 GMT

{
      "gtin": "00074470101505"
          
}

$ curl -i -H "Content-Type: application/json" -X POST -d '{"upc":"63050947716"}' http://10.46.39.75:5000/gtin/api/v1.0/convert

{
  "gtin": "630509477166"
}

Notes

Had to upgrade python from alpine to stretch.

-FROM python:3.4-alpine
+FROM python:3.7-stretch

Alpine seems not working with Centos 7, with Docker 1.12.

CentOS Linux release 7.3.1611 (Core)
3.10.0-514.26.2.el7.x86_64
$ docker --version
Docker version 1.12.6, build 88a4867/1.12.6
