如何在创建asp.net核心web api时将数据加载到缓存层？

using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Caching.Memory;

namespace YourNamespace.Controllers
{
    [ApiController]
    [Route("api/[controller]")]
    public class YourController : ControllerBase
    {
        private readonly IMemoryCache _cache;

        public YourController(IMemoryCache cache)
        {
            _cache = cache;
        }

        [HttpGet]
        public IActionResult GetData()
        {
            string cacheKey = "yourCacheKey";
            if (_cache.TryGetValue(cacheKey, out string cachedData))
            {
                return Ok(cachedData);
            }

            // 如果缓存中不存在数据，则从数据源获取数据
            string data = GetDataFromDataSource();

            // 将数据存储到缓存中，设置过期时间等缓存选项
            var cacheOptions = new MemoryCacheEntryOptions()
                .SetSlidingExpiration(TimeSpan.FromMinutes(10));
            _cache.Set(cacheKey, data, cacheOptions);

            return Ok(data);
        }

        private string GetDataFromDataSource()
        {
            // 从数据源获取数据的逻辑
            // 可以是数据库查询、API调用等

            return "Your data from data source";
        }
    }
}
