User city and region detection

[GoulvenF]

Version française (google translate)

Problem

• We will need to operate user localisation, to allow funding of local causes
• but we will need to make in in a GDPR respectuous way and in a "no cookie" mode

Solution

• Implement a cool spring filter, that allows user localisation based on its ip.

Requisites

• Will have to cross check with INSEE data, to retrieve country code, region, postal code and so, for france in a first time.
• must be fast, and provide a short window IP caching mechanism.
• should be a spring approach, or something that can easily be applied in spring context

Tips / work tracks

• Can have a look at the commented commons/src/main/java/org/open4goods/services/GeolocService.java, a dirty maxmind implementation of this kind of stuf
• maybe something exists, or could be a new, separate spring boot starter project ?

I want to work on this. May I know what is the problem with maxmind implementation?

Hi Ashwinn,

Thanks again for tour interest in the project ! Nothing bad with maxmind, but a cool reusable spring filter (interceptor ?) that embeds maxmind geolocation, with IP resolution caching and plugable location information extension (an example for france here : https://www.data.gouv.fr/fr/datasets/communes-de-france-base-des-codes-postaux/) would be very cool !

Not an so easy part, and the "localized" operations (eg : regions enrichment) could/should probably be delayed.
