Get location information from ip address

[Nicklas Nordborg]

When we create a new login session, we register the ip address in the "Remote ID" field. With the help of a service like ​http://freegeoip.net we could get some information about the actual location of the ip. The service has a simple JSON-based API. For example:

http://freegeoip.net/json/130.235.5.57 ==>
{
  "ip": "130.235.5.57",
  "country_code": "SE",
  "country_name": "Sweden",
  "region_code": "M",
  "region_name": "Skåne",
  "city": "Lund",
  "zip_code": "220 02",
  "time_zone": "Europe/Stockholm",
  "latitude": 55.7,
  "longitude": 13.1833,
  "metro_code": 0
}

It is even possible to setup a local server: ​https://github.com/fiorix/freegeoip

The server URL should be specified by an option in base.config and if not set, the location lookup should be disabled.

Location information is now stored on sessions and devices when a user is logging in. The actual location lookup is not yet implemented. base.config has been prepared with a setting for the service to use for this.

List and view pages display the location and provide a link to a map. The default setting in base.config uses OpenStreetMap, but other services can be used as well as long as they accept at latitude and longitude.

Location lookup implemented. Requires a bit of careful error handling since we do not want a failure or delay in this feature to prevent a user from loggin in.

• Before trying to lookup the location, we check that the remote id seems like an ip address.
• We do not allow more than 3 seconds.
• The lookup service must return a HTTP status 200
• It must return "application/json" content type
• It must not return more than 1kB of data.

Updating failed since we log in with a null 'ip'.
