How to implement geoinformation in node.js and mongodb

I saw several examples of using geoip in node.js such as https://github.com/kuno/GeoIP.git and https://github.com/wadey/node-geoip . However, I want to display a map showing geoip for a specific user in the log. How can it be implemented.

You can get the geolocation database (for example, http://www.maxmind.com ) and save it in mongo. Each entry contains an IP range (start / end) and latitude / longitude associated with that IP range. IP addresses are represented as integers. You can create an index in the field startand execute a query on mongo to find the record with the highest value startthat is less than the IP address of your client and see the corresponding lat / lon.

Regarding building a map using this lat / lon, it’s very easy to create a google map that is concentrated in a specific place: (View source at: http://code.google.com/apis/maps/documentation/javascript/v2/examples /map-simple.html )

GeoIP https://github.com/kuno/GeoIP, ( , ), Maxmind, , .

MongoDB, . Node.js.

:

// Open the GeoLiteCity.dat file first.
var City = geoip.City;
var city = new City('/path/to/GeoLiteCity.dat');
console.log(city); // this contains country, city, lat, long, continent, postal code etc

Python:

#!/usr/bin/python
#coding: utf-8
import os
import pygeoip


gi = pygeoip.GeoIP('GeoIP.dat')
gic = pygeoip.GeoIP('GeoIPCity.dat')


fl = file(r'apache-unique.log')
lines = fl.readlines()

for line in lines:
    print gi.country_code_by_addr(line)
    print gic.record_by_addr(line)

os.system('pause')
