Azure Function Update Leaderboard Problem

In the Visual Studio Installer I have installed Azure Development ("Desarrollo de Azure") and with that I have managed to create Azure Functions that have worked perfectly.

The problem that I have is that I want to update an statistic (my game has leaderboards) with the Azure Function that you have below.

using System;
using System.IO;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;
using PlayFab.Samples;


namespace FuncionRankingPrueba1
{
    public static class RankingPrueba
    {
        [FunctionName("UpdateRanking")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            string name = req.Query["name"];
            string time = req.Query["time"];


            string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
            dynamic data = JsonConvert.DeserializeObject(requestBody);
            name = name ?? data?.FunctionArgument?.name;
            time = time ?? data?.FunctionArgument?.time;
            float timeFloat = Single.Parse(time);

            var request = new UpdatePlayerStatisticsRequest
            {
                Statistics = new List<StatisticUpdate>
            {
                new StatisticUpdate
                {
                    StatisticName = name, Value = timeFloat
                }
            }
            };
            var result = server.UpdatePlayerStatistics(request);
            return new OkObjectResult(result);
        }
    }
}

I don't know if it is the correct way of doing it, but the problem that I face is that I don't manage to publish the function to Azure because these names are not found:

- UpdatePlayerStatisticsRequest

- List

- StatisticUpdate

- Playfab

I assume that Azure doesn't find the Playfab library, but I don't know how to add it to Visual Studio.

[Edited]Referring to Quickstart - PlayFab Client library for C# - PlayFab | Microsoft Docs, use the Nuget package manager to add PlayFabAllSDK, then add the following reference.

using PlayFab;

using PlayFab.ServerModels;

Regarding List, you need to add the following reference.

using System.Collections.Generic;

Also, you can delete the following two lines as they don't work in CSAF.

string name = req.Query["name"];
string time = req.Query["time"];

You can refer to the following code to further improve:

[FunctionName("UpdatePlayerStatistics")]
        public static async Task<dynamic> Run(
            [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            string name; // = req.Query["name"];
            string time; // = req.Query["time"];
            string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
            dynamic data = JsonConvert.DeserializeObject(requestBody);
            name = data?.FunctionArgument?.name;
            time = data?.FunctionArgument?.time;
            //float timeFloat = Single.Parse(time);
            int timeFloat = int.Parse(time);

            var request = new UpdatePlayerStatisticsRequest
            {
                PlayFabId = data.CallerEntityProfile.Lineage.MasterPlayerAccountId,
                Statistics = new List<StatisticUpdate>
            {
                new StatisticUpdate
                {
                    StatisticName = name, 
                    Value = timeFloat
                }
            }
            };
            var apiSettings = new PlayFabApiSettings
            {
                TitleId = data.TitleAuthenticationContext.Id,
                DeveloperSecretKey = Environment.GetEnvironmentVariable("PLAYFAB_DEV_SECRET_KEY", EnvironmentVariableTarget.Process),
            };
            var serverApi = new PlayFabServerInstanceAPI(apiSettings);
            return await serverApi.UpdatePlayerStatisticsAsync(request);
        }

Thanks for the answer @Made Wang. I appreciate it. I am facing a new problem.

This is the only part of your code that I've changed.

var serverApi =newPlayFabServerInstanceAPI(apiSettings);
return(IActionResult)await serverApi.UpdatePlayerStatisticsAsync(request);

I have had to add the (IActionResult) because otherwise it gives the error: "you can't convert the type "PlayFab.PlayFabResult<PlayFab.ServerModels.UpdatePlayerStatisticsResult>" in Microsoft.AspNetCore.Mvc.IActionResult".

The problem that I'm facing is that I can publish it without problem, but when I run this code from my project, where Prueba3 is the azure function that I've published, it gives this error:

"CloudScript/ExecuteFunction: Invocation of cloud script function Prueba3 failed"

If I simplify the azure function to only return the string (Level1Times) and integer (23), it works fine. It is only when I add the request that it fails.

This is my final code:

namespace FuncionRankingPrueba1
{
    public static class RankingPrueba
    {
        [FunctionName("UpdateRanking")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            string name; 
            string time; 
            string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
            dynamic data = JsonConvert.DeserializeObject(requestBody);
            name = data?.FunctionArgument?.name;
            time = data?.FunctionArgument?.time;
            int timeint=  int.Parse(time);
            var request = new UpdatePlayerStatisticsRequest
            {
                PlayFabId = data.CallerEntityProfile.Lineage.MasterPlayerAccountId,
                Statistics = new List<StatisticUpdate>
            {
                new StatisticUpdate
                {
                    StatisticName = name,
                    Value = timeint
                }
            }
            };
            var apiSettings = new PlayFabApiSettings
            {
                TitleId = data.TitleAuthenticationContext.Id,
                DeveloperSecretKey = Environment.GetEnvironmentVariable("PLAYFAB_DEV_SECRET_KEY", EnvironmentVariableTarget.Process),
            };
            var serverApi = new PlayFabServerInstanceAPI(apiSettings);
            return (IActionResult)await serverApi.UpdatePlayerStatisticsAsync(request);
        }
    }
}

The problem that I'm facing is that I can publish it without problem, but when I run this code from my project, where Prueba3 is the azure function that I've published, it gives this error:

    {

        PlayFabCloudScriptAPI.ExecuteFunction(new ExecuteFunctionRequest()
        {
            Entity = new PlayFab.CloudScriptModels.EntityKey()
            {
                Id = PlayFabSettings.staticPlayer.EntityId, 
                Type = PlayFabSettings.staticPlayer.EntityType, 
            },
            FunctionName = "Prueba3", 
            FunctionParameter = new {name= "Level1Times", time="23"},
            GeneratePlayStreamEvent = false 
        }, (ExecuteFunctionResult result) =>
        {
            Debug.Log($"The {result.FunctionName} function took {result.ExecutionTimeMilliseconds} to complete");
            Debug.Log($"Result: {result.FunctionResult.ToString()}");
        }, (PlayFabError error) =>
        {
            Debug.Log($"Opps Something went wrong: {error.GenerateErrorReport()}");
        });
    }

Error: "CloudScript/ExecuteFunction: Invocation of cloud script function Prueba3 failed"

Sorry for my carelessness, you need to change the IActionResult to dynamic so that you don't need to typecast when returning the result, as follows.

public static async Task<dynamic> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
            ILogger log
