Developers can add their own custom logic here.

using System;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Host;
using Microsoft.Extensions.Logging;

public static class MyFunction
{
    [FunctionName("MyFunction")]
    public static void Run(
        [QueueTrigger("myqueue-items", Connection = "AzureWebJobsStorage")] string myQueueItem,
        ILogger log)
    {
        log.LogInformation($"C# Queue trigger function processed: {myQueueItem}");
        // Add your custom logic here
        Console.WriteLine("Function executed successfully!");
    }
}

Command to Use to Deploy Azure Function

To deploy this function, you can use the Azure portal, Visual Studio, or Azure CLI. Here’s an example of deploying the function using Azure CLI. Make sure to replace “my-function.zip” with the path to your function code packaged as a zip file. Also, update “my-resource-group” and “my-function-app” with the appropriate names for your Azure resource group and function app.

It takes a name parameter from the query string or the request body and responds with a personalized greeting message. The main function serves as the entry point for the Azure Function. It receives an HttpRequest object, which represents the incoming HTTP request. The function extracts the name from either the query string or the request body and constructs a response with a personalized greeting or an error message if the name is missing.

import logging
import azure.functions as func

def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    name = req.params.get('name')
    if not name:
        try:
            req_body = req.get_json()
        except ValueError:
            pass
        else:
            name = req_body.get('name')

    if name:
        return func.HttpResponse(f"Hello, {name}! This is a Python HTTP trigger function.")
    else:
        return func.HttpResponse(
             "Please pass a name on the query string or in the request body",
             status_code=400
        )
