Fifconfig: my ifconfig.me ripoff

I used ifconfig.me recently to show my public IP address, and I decided that I could write my own utility for that. I know that in Flask, the request object has all sorts of properties.

So I wrote my own version, which I call Flask-ifconfig, or fifconfig.

I made mine handle the 'Accept' header for json, html, xml, and text. You could also use a parameter, i.e., ?json to force that return type.

You can check out the code at my cgit site.

README for fifconfig

Upstream

gitlab author's git

Features

Provide different output type based on Accept header or url parameter. Options include:
application/json or ?json
text/html or ?html
application/xml or ?xml
text/plain or ?text
Display IP address as viewed by the web server, or else the first entry of HTTP_X_FORWARDED_FOR.

Using fifconfig

Visit the application.

curl -L https://bgstack15.ddns.net/ifconfig/?json | jq

Installing

You can use flask for development, and uwsgi for production.

Instructions

Configure the application with these two files, based on the .example files available in the source code:

fifconfig.conf
fifconfig.wsgi.ini

Development

Run server in development mode.

FLASK_APP=fifconfig.py FLASK_DEBUG=True flask run --host='0.0.0.0'

Production

Run the server in a full wsgi environment for the cleanup timer to operate.

./fifconfig.bin

The html responses include links to the various single-field pages, unless you add a parameter ?nolinks. These links depend on any reverse-proxy servers adding themselves correctly to header X-Forwarded-For.

Alternatives

This project was a ripoff of love of http://ifconfig.me.
