User city and region detection

GoulvenF commented 3 months ago

[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?

GoulvenF commented 2 months ago

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.
