[ASP. NET Web API] Cache

Summary

In order to improve the performance of the interface, the optimizations we often do include caching, which caches data that is frequently accessed but does not change much. or use the HTTP cache to reduce the number of requests.

Web API Caching

In the API provided, we can also implement the cache to reduce the number of accesses. There is a better component for us to use.

Installing WebApi.OutputCache.V2 open source components through NuGet, project address: Https://github.com/filipw/Strathweb.CacheOutput

Use

[Routeprefix ("Api/user")]     Public classUsercontroller:apicontroller {PrivateList<user>_lstusers;  PublicUsercontroller () {_lstusers=NewList<user>()            {                Newuser{id=1, name="wolfy1"},                Newuser{id=2, name="wolfy2"},                Newuser{id=3, name="Wolfy3"},                Newuser{id=4, name="Wolfy4"},                Newuser{id=5, name="wolfy5"},            }; }        /// <summary>        ///Cache 120s/// </summary>        /// <returns></returns>[HttpGet] [Route (" All")] [Cacheoutput (Clienttimespan= -, Servertimespan = -)]         Publichttpresponsemessage GetAll () {httpresponsemessage response=Request.createresponse (); Response. StatusCode=Httpstatuscode.ok; Response. Content=NewStringcontent (Jsonconvert.serializeobject (New{_code = $, _data =_lstusers}),
SYSTEM.TEXT.ENCODING.UTF8); returnresponse; }    }

Test

First time visit

Second Refresh

In debug mode, the second time does not enter the endpoint, and no request is initiated.

Summarize

When optimizing the query interface, you can use this component for caching optimizations if the data is not changing very frequently. For additional parameters of the component, refer to the documentation provided in its project address.
