我尝试在Asp.Net Core应用程序中实现Redis缓存,但是它没有在HttpContext.Session中设置任何值,甚至没有返回任何值。这是我的startup.cs文件。
public void ConfigureServices(IServiceCollection services)
{
services.AddDistributedRedisCache(options =>
{
options.InstanceName = Configuration.GetValue<string>("redis:name");
options.Configuration = Configuration.GetValue<string>("redis:host");
});
services.AddSession(o=> { o.IdleTimeout = TimeSpan.FromMinutes(5); });
services.AddMvc();
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
// The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
app.UseHsts();
}
app.UseSession();
app.UseStaticFiles();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
}
Appsetting.json
"redis": {
"host": "redis-17930.c1.ap-southeast-1-1.ec2.cloud.redislabs.com",
"port": 17930,
"name": "Astroyogi"
},
HomeController.cs
public IActionResult Index()
{
var helloRedis = Encoding.UTF8.GetBytes("Hello Redis");
HttpContext.Session.Set("hellokey", helloRedis);
var getHello = default(byte[]);
HttpContext.Session.TryGetValue("hellokey", out getHello);
ViewData["Hello"] = Encoding.UTF8.GetString(getHello);
return View();
}
和我安装的库- Microsoft.Extensions.Caching.Redis Microsoft.AspNetCore.Session
,它不会在会话中设置任何值。 请帮助我卡住的地方。

在同一请求中,您不能同时设置和获取刚刚在Session
中设置的值。会话需要设置一个cookie,只有在您返回响应后才会发生。在下一个请求时,您应该可以正常使用自己的值。
