GeoIpServices 3.1.0

GeoIpServices(https://www.nuget.org/packages/GeoIpServices)

GeoIpServices is an open-source C# class library that provides a wrapper around existing services that serve information about the IP. The service stores information in a MongoDb database that you configure using the package MongoDbService

Features

• Covers IpStack
• Cache information in your own MongoDB instance to reduce usage of the various services

Getting Started

NuGet Package

To include GeoIpServices in your project, install the NuGet package:

dotnet add package GeoIpServices

Then in your appsettings.json add the following sample configuration and change the values to mtch the details of your MongoDB instance.

  "GeoIpSettings": {
    "Controls": {
      "SessionTimeoutInSeconds": 240,
      "MaxRoundRobinAttempts": 2,
      "Priority": [ "IpStack" ]
    },
    "IpStack": {
      "ApiPrefix": "https://api.ipstack.com/",
      "ApiPostfix": "MovedToSecret"
    }
  }

After the above is done, you can just Dependency inject the GeoIpService in your C# class.

For example:

Then you have an endpoint that gives you info about the IP of the visitor.

using GeoIpServices;
using Microsoft.AspNetCore.Mvc;
using MongoDbService;
using System.Net;
using System.Net.Sockets;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

builder.Services.AddMongoDbServices();
builder.Services.AddGeoIpServices();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
	app.UseSwagger();
	app.UseSwaggerUI();
}


app.MapGet("/ipinfo", async ([FromServices] GeoIpService geoIpService, HttpRequest httpRequest) =>
{
	return await geoIpService.GetGeoIpInfoFromIpv4(GetOriginIpV4(httpRequest));
})
.WithName("GetGeoIpInfoFromIpv4")
.WithOpenApi();

IPAddress? GetOriginIpV4(HttpRequest httpRequest)
{
	var xForwardedForHeader = httpRequest.Headers["X-Forwarded-For"];
	var ipString = xForwardedForHeader.Select(s => s.Trim()).FirstOrDefault();
	if (string.IsNullOrWhiteSpace(ipString) || !IPAddress.TryParse(ipString, out IPAddress? clientIpAddress))
	{
		return null;
	}
	if (clientIpAddress.AddressFamily == AddressFamily.InterNetworkV6)
	{
		// If it's an IPv6 address, convert to IPv4
		return clientIpAddress.MapToIPv4();
	}
	return clientIpAddress;
}

app.Run();
