WebAPI core 2.0 Cache by post params

Question

I am building an pure json api and I want to cache response according to post params. Is there any similar way like VaryByQueryKeys? Maybe some custom cache middleware or?

Of course I can use MemoryCache but wonder maybe there is some "build in" practice.

Check this thread here: WebAPI caching for http Post

Do you really need HttpPost request to fulfill your requirements? Have you considered using GET request and then leverage client side caching?

Yes our API is pure JSON api with using POST 99% – Vytautas Pranskunas May 02 '18 at 07:10
For pure Json API with POST method, you will need to cache data on server side using MemCache or Redis or any other caching provider. – Mohsin Mehmood May 02 '18 at 19:47
What is disadantage to use just MemryCache vs MemCache? – Vytautas Pranskunas May 03 '18 at 20:29

Of course shouldn't expect caching in post API

But look at this sample code on special controller not in middleware and it is not "build in"

May be useful

  public class XController : Controller
   {
    private readonly IMemoryCache _cache;
    public XController(IMemoryCache cache)
    {
        _cache = cache;
    }

    [HttpPost]
    public async Task<IEnumerable<YourCustomModel>> Post([FromBody] ParamtersModel value)
    {
        string cacheKey = value.Id.ToString();
        IEnumerable<YourCustomModel> cacheEntry = await _cache.GetOrCreate(cacheKey, async entry =>
        {
            entry.AbsoluteExpirationRelativeToNow = TimeSpan.FromSeconds(60);
           
            IEnumerable<YourCustomModel> result = await ... your method calling for first time to getting in cache
            return result;

        });
        return cacheEntry;
    }

   }
