HOW TO RETURN CLIENT IP IN AZURE FUNCTIONS

Question

Hi Reader !

I need to get client IP in azure functions.

Need to create such function which could get me Client IP i.e the IP of the machine which calls the function. And i want to call the function using business central. But i am in doubt if it could be achieved.

I already Tried running certain scripts in powershell in azure function but none seem to do proper justice.

Would appreciate your help.

Thank you and have a great day ahead :)

To get the client IP in Azure Functions, you can use the HttpRequest object's HttpContext.Connection.RemoteIpAddress property. Here's an example code snippet in C#:

using Microsoft.AspNetCore.Http;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;

public static async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
    ILogger log)
{
    var clientIp = req.HttpContext.Connection.RemoteIpAddress.ToString();
    log.LogInformation($"Client IP: {clientIp}");
    return new OkObjectResult(clientIp);
}

This code snippet uses the HttpTrigger attribute to create an HTTP-triggered Azure Function that accepts GET and POST requests. The HttpRequest object is used to get the client IP address, which is then logged and returned as the response.
