我尝试了解 .NET Core 3.1 中的响应缓存。但它并没有如我所愿。我在 Chrome devtool 中查看了网络，它显示了带有cache-control: no-cache, no-store.

我还发现 Response headerHeaderCacheControl{public,max-age=100}在 Actionfilter 中。这是我期望的值，但浏览器中的实际响应标头是no-cache.

Startup类\xef\xbc\x9a

public void ConfigureServices(IServiceCollection services)\n{\n    services.AddResponseCaching(options=> \n    {\n        options.SizeLimit = 1024;\n        options.MaximumBodySize = 1024 * 1024 * 100;\n        options.UseCaseSensitivePaths = false;\n    });\n}\n\npublic void Configure(IApplicationBuilder app, IWebHostEnvironment env)\n{   \n    if (env.IsDevelopment())\n    {\n        app.UseDeveloperExceptionPage();\n    }\n    app.UseCookiePolicy();\n    app.UseStaticFiles();\n    app.UseRouting();\n    app.UseAuthentication();\n    app.UseAuthorization();\n    app.UseResponseCaching();\n    app.UseEndpoints(endpoints =>\n    {\n        endpoints.MapControllerRoute(\n            name: "default", \n            pattern: "{controller=Home}/{action=Index}/{id?}");\n    });\n}\n
