NCache作为缓存优点币Redis有优势,但是收费的所以选用的不多吧。下面简单实操一下:
首先官网下载组件NCache Download Center (alachisoft.com),这里选择企业和专业版都可以,都只有一个月试用期,下一步后统一协议,后弹出第二个界面需要填写一下注册信息。重点是workemail,这里需要工作邮箱,后缀是qq,163的都不行。我用的是zoho的邮箱。
下载完毕后需要通过cmd管理员命令去安装msi的文件,因为msi不能通过右键管理员来执行,二这个必须要管理员权限(有疑问 搜索管理员身份运行msi安装),安装过程中需要安装key,注册的邮箱里面有这个。
安装完后会有这几个出现在开始菜单,只需要打开NCache Web Manager,可以打开localhost:8251的管理界面。Cache Name和Servers需要在代码和配置文件中做好配置。
下面新建netcore6 webapi程序,导入NCache的包会自动生成:client.ncconf和config.ncconf两个配置文件,重点修改client.ncconf文件的两处服务ip,还有代码
configuration.CacheName = "ClusteredCache"; 指定CacheName名称为上图的Cache Name。
using Alachisoft.NCache.Caching.Distributed;
using Microsoft.Extensions.Caching.Distributed;
using Microsoft.Extensions.Caching.SqlServer;
using Microsoft.Extensions.Caching.StackExchangeRedis; var builder = WebApplication.CreateBuilder(args); builder.Services.AddRazorPages(); builder.Services.AddNCacheDistributedCache(configuration =>
{
configuration.CacheName = "ClusteredCache";
configuration.EnableLogs = true;
configuration.ExceptionsEnabled = true;
}); var app = builder.Build(); #region snippet_Configure
app.Lifetime.ApplicationStarted.Register(() =>
{
var currentTimeUTC = DateTime.UtcNow.ToString();
byte[] encodedCurrentTimeUTC = System.Text.Encoding.UTF8.GetBytes(currentTimeUTC);
var options = new DistributedCacheEntryOptions()
.SetSlidingExpiration(TimeSpan.FromSeconds(20));
app.Services.GetService<IDistributedCache>()
.Set("cachedTimeUTC", encodedCurrentTimeUTC, options);
});
#endregion if (!app.Environment.IsDevelopment())
{
app.UseExceptionHandler("/Error");
app.UseHsts();
} app.UseHttpsRedirection();
app.UseStaticFiles(); app.UseRouting(); app.UseAuthorization(); app.MapRazorPages(); app.Run();
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;
using Microsoft.Extensions.Caching.Distributed;
using System.Text; namespace SampleApp.Pages
{
#region snippet_IndexModel
public class IndexModel : PageModel
{
private readonly IDistributedCache _cache; public IndexModel(IDistributedCache cache)
{
_cache = cache;
} public string? CachedTimeUTC { get; set; }
public string? ASP_Environment { get; set; } public async Task OnGetAsync()
{
CachedTimeUTC = "Cached Time Expired";
var encodedCachedTimeUTC = await _cache.GetAsync("cachedTimeUTC"); if (encodedCachedTimeUTC != null)
{
CachedTimeUTC = Encoding.UTF8.GetString(encodedCachedTimeUTC);
} ASP_Environment = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");
if (String.IsNullOrEmpty(ASP_Environment))
{
ASP_Environment = "Null, so Production";
}
} public async Task<IActionResult> OnPostResetCachedTime()
{
var currentTimeUTC = DateTime.UtcNow.ToString();
byte[] encodedCurrentTimeUTC = Encoding.UTF8.GetBytes(currentTimeUTC);
var options = new DistributedCacheEntryOptions()
.SetSlidingExpiration(TimeSpan.FromSeconds(20));
await _cache.SetAsync("cachedTimeUTC", encodedCurrentTimeUTC, options); return RedirectToPage();
}
}
#endregion
}
运行效果图如下:
