외부 API 호출

1. API 호출을 처리할

   CatFactsApi

   클래스를 선언합니다.

   using Newtonsoft.Json;using RestSharp;using Unity.Services.CloudCode.Core;using Unity.Services.CloudCode.Shared;namespace CatFacts;public interface ICatFactsApi{    public Task<CatFactsApiResponse?> GetCatFact();}public class CatFactsApiResponse{    public string fact { get; set; }    public int length { get; set; }}public class CatFactsApi : ICatFactsApi{    private readonly RestClient _httpClient;    public CatFactsApi()    {        // It's important to only create one RestClient per service in order to avoid creating and destroying too many network connections which could hurt performance        _httpClient = new RestClient("https://catfact.ninja/fact");    }    public async Task<CatFactsApiResponse?> GetCatFact()    {        var request = new RestRequest();        try        {            var res = await _httpClient.ExecuteGetAsync(request);            return JsonConvert.DeserializeObject<CatFactsApiResponse?>(res.Content);        }        catch (ApiException e)        {            throw new Exception($"Failed to get cat fact: {e.Message}");        }    }}

2. ModuleConfig

   클래스에서

   CatFactsApi

   클래스를 싱글톤으로 선언합니다.

       public class ModuleConfig : ICloudCodeSetup    {        public void Setup(ICloudCodeConfig config)        {            config.Dependencies.AddSingleton<ICatFactsApi>(new CatFactsApi());        }    }

3. CatFactsApi

   클래스의

   GetCatFact

   메서드를 호출하는

   GetCatFact

   함수를 선언합니다.

   using Microsoft.Extensions.DependencyInjection;using Microsoft.Extensions.Logging;using Unity.Services.CloudCode.Core;using Unity.Services.CloudCode.Shared;namespace CatFacts;public class CatFactsSample{    private static ILogger<CatFactsSample> _logger;    public CatFactsSample(ILogger<CatFactsSample> logger)    {        _logger = logger;    }    [CloudCodeFunction("GetCatFact")]    public async Task<CatFactsApiResponse?> GetCatFact(ICatFactsApi catFactsApi)    {        try        {            var fact = await catFactsApi.GetCatFact();            _logger.LogInformation("Cat fact: {fact}", fact?.fact);            return fact;        }        catch (ApiException e)        {            _logger.LogError("Failed to get cat fact. Error: {Error}", e.Message);            throw new Exception($"Failed to get cat fact: {e.Message}");        }    }    public class ModuleConfig : ICloudCodeSetup    {        public void Setup(ICloudCodeConfig config)        {            config.Dependencies.AddSingleton<ICatFactsApi>(new CatFactsApi());        }    }}

4. 게임 클라이언트에서

   GetCatFact

   함수를 호출합니다. 이 함수는 고양이에 관한 무작위 정보를 반환합니다.

   {    "output": {        "fact": "The Amur leopard is one of the most endangered animals in the world.",        "length": 68    }}
