How to get user location from a web service in c#

-

Introduction


Have you ever wondered on how to get user location based on the network the user is currently on? Maybe you want to display the user country based on location or you want to disable some countries that shouldn't access your app, Your in the right place!!!

freegeoip.net provides a public HTTP API for software developers to search the geolocation of IP addresses. It uses a database of IP addresses that are associated to cities along with other relevant information like time zone, latitude and longitude.

Let's see some codes in C#.

C# Impelmentation


1. Create a Location class that will be used as a data transfer object. It will contain properties to hold the data return from the web service.




















2. Call the ReadAsync<T> method of  the HttpClient Class. The method will handle serialization of object to the response object.























Let's play with it a little

   
if(currentLocation == "Nigeria"){
      //allow
}else{
    //deny
}


Run it in the console and you would be surprised by what you see.

NodeJS Implementation

Coming soon...

Conclusion


I hope you have all enjoyed your way through this tutorial, it's been fun coding this. This kind of code can also be used for security reasons and i personally use it in my projects and it has been working for me. If you have a better implementation, lets see it.

Remember my post on how to implement a payment gateway on Paystack with Node js ? today, you would see it in action in Asp.Net . I am not going to build a customer subscription app like I did in the previous one, rather I would provide explicit codes that can be used to implement payment on any mobile apps, web apps, and any platform indeed. It is a simple code and can be easily integrated into your projects. To know more about Paystack infrastructure, visit the developer's section on their website. They have already written some libraries on vast programming languages like Python , Java , Node js and so on... If you have problems working with the code or implementing it on your project, drop your comments and you might receive an email from me or if your company is looking forward to incorporating a payment solution, you can contact me.

There are different token providers out there, but the one people are more familiar with is the JWT token. The token identifies a user. For example, your ID card could be used as a token. It identifies who you claim to be. The Id card would contain information like: ·         Firstname ·         Lastname ·         Age ·          Title The JSON Web Token The JSON Web Token contains some header information, a signature, and the token’s claims. In plain text, the claims might look like this: { "Name":"John doe", "UserId":5, "Email":"johndoe@gmail.com", "Role":"Boss" } The token header is used to specify some other things like signature algorithm, expiration date, the name of the issuer, and a few other attributes. Using Jwt In Asp.Net Web API The JwtA...
