我似乎无法在ASP.NET Core 2.2中启用静态文件的缓存。我的 Configure 中有以下内容:
I can't seem to enable caching of static files in ASP.NET Core 2.2. I have the following in my Configure:
public void Configure(IApplicationBuilder app, IHostingEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); app.UseCors(...); } else { app.UseHsts(); } app.UseHttpsRedirection(); app.UseAuthentication(); app.UseSignalR(routes => { routes.MapHub<NotifyHub>("/..."); }); app.UseResponseCompression(); app.UseStaticFiles(); app.UseSpaStaticFiles(new StaticFileOptions() { OnPrepareResponse = (ctx) => { ctx.Context.Response.Headers[HeaderNames.CacheControl] = "public, max-age=31557600"; // cache for 1 year } }); app.UseMvc(); app.UseSpa(spa => { spa.Options.SourcePath = "ClientApp"; if (env.IsDevelopment()) { spa.UseVueCli(npmScript: "serve", port: 8080); } }); }当我尝试使用chrome在HTTPS上审核生产站点时,我不断收到使用有效的缓存策略为静态资产提供服务:
When I try and Audit the production site on HTTPS using chrome I keep getting "Serve static assets with an efficient cache policy":
在网络选项卡中,标题中没有提及缓存,当我按F5键时,似乎所有内容都由磁盘缓存提供。但是,如果审核未显示,我如何确定我的缓存设置正常?
In the network tab there is no mention of caching in the headers, when I press F5 it seems everything is served from disk cache. But, how can I be sure my caching setting is working if the audit is showing its not?
推荐答案
我不知道 UseSpaStaticFiles 是什么,但是您可以在 UseStaticFiles 中添加缓存选项。您错过了设置 Expires 标头的操作。
I do not know what UseSpaStaticFiles is but you can add cache options in UseStaticFiles. You have missed to set an Expires header.
// Use static files app.UseStaticFiles(new StaticFileOptions { OnPrepareResponse = ctx => { // Cache static files for 30 days ctx.Context.Response.Headers.Append("Cache-Control", "public,max-age=2592000"); ctx.Context.Response.Headers.Append("Expires", DateTime.UtcNow.AddDays(30).ToString("R", CultureInfo.InvariantCulture)); } });请注意,对静态文件进行更改时,还需要一种使缓存无效的方法。
