如何将Console App的代码块转换为Azure Function的代码块？

Question

I've written my sample console application and it's complied and get the data well. Now I want to test it as an Azure Function. The following are the code blocks in console app. How can I rewrite it as Azure's time-trigger function? Thanks.

using System;
using System.IO;
using System.Threading.Tasks;
using Newtonsoft.Json.Linq;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Services;

namespace Google.Apis.Samples

internal class MyData
{
    [STAThread]
    static void Main(string[] args)
    {
        Console.WriteLine("Blah Blah Blah");
        Console.WriteLine("==============");

        try
        {
            new MyData().Run().Wait();
        }
        catch (AggregateException ex)
        {
            foreach (var e in ex.InnerExceptions)
            {
                Console.WriteLine("Error: " + e.Message);
            }
        }
    }
    private async Task Run()
    {
    // I can either use service account or supply api key.
    // How do I read a JSON file from Azure function?
    // then I can Get data and display results.
    }
}

Answer 1

So I got this finally.

I used Azure Function Template in VS2017.

I need to add NuGet Packages (I had to use Azure V2 to match dependency requirement). And I just have to put all the codes inside of private async Task Run() of Console App to Azure Function 's public static void Run([TimerTrigger( ... .

I have yet to publish and test it on Azure. And by the way, Azure Storage Emulator has to be initialized and started with Admin mode in Windows CMD.

I'm not sure what is your intention, but if you want to encode your code in an azure function maybe this can help you.

in order to read a json file you can use :

  FileStream fs = new FileStream(@"your_json", FileMode.Open)

Here you code in one Azure Function

using System.Net;
using System.IO;

public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log)
{
    log.Info("Blah Blah Blah");
    log.Info("==============");

    try
        {
            await Run_Function();
        }
        catch (AggregateException ex)
        {
            foreach (var e in ex.InnerExceptions)
            {
                log.Info("Error: " + e.Message);
            }
        }


     return req.CreateResponse(HttpStatusCode.OK, "OK");
}

 private static Task Run_Function()
    {
    // I can either use service account or supply api key.
    // How do I read a JSON file from Azure function?
      using (FileStream fs = new FileStream(@"your_json", FileMode.Open))
        {
                // then I can Get data and display results.                
        }
    return null;
    }
