本文介绍了Asp.Net 核心“记住我"部署后持久性 cookie 不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经构建了一个 MVC Core(框架)应用程序，并使用 Identity 登录.当我点击记住我"选项时，在我的开发机器上一切正常，但在服务器机器上部署后，记住我"在 30 分钟后无法保持登录.
I've built an MVC Core (Framework) application and I use Identity to login. When I click "Remember me" option all is ok on my develop machine, but after deploy on server machine, "remember me" doesn't maintain login after 30 minutes.
我尝试检查是否设置了 cookie 到期日期并且似乎没问题，同样在服务器机器上，cookie 似乎设置得很好.您可以在下图中查看我的 cookie 详细信息:
I tried to check if cookie expiry date is set and seems to be ok, also on server machine the cookie seems well set. You can see my cookies detail in following image:
谁能帮我解决这个问题?
Can anyone help me to solve this issue?
提前感谢您的回复:)
根据 Orhun 的要求，我在 Startup.cs 内容下方添加:
As required by Orhun, I add below my Startup.cs content:
public partial class Startup
{
public SymmetricSecurityKey signingKey;
public Startup(IHostingEnvironment env)
{
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);
if (env.IsDevelopment())
{
// For more details on using the user secret store see https://go.microsoft.com/fwlink/?LinkID=532709
builder.AddUserSecrets<Startup>();
}
builder.AddEnvironmentVariables();
Configuration = builder.Build();
}
public IConfigurationRoot Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
///////////////////////////
// Custom Services - START
///////////////////////////
string conn = CreateConnectionString(Configuration.GetConnectionString("TiesseWebConnection"));
services.AddScoped<System.Data.Entity.DbContext>((_) => new TiesseWeb.DAL.TiesseWebEntities(conn)); //Configuration["Data:DefaultConnection:ConnectionString"]));
// SESSION section
services.AddMemoryCache();
services.AddDistributedMemoryCache();
services.AddSession();
services.AddSingleton<IConfiguration>(Configuration); // IConfiguration explicitly
// Add functionality to inject IOptions<T> (important for inject Config object)
services.AddOptions();
// Add our Config object so it can be injected
services.Configure<Settings>(Configuration.GetSection("Settings"));
// Add our Config object so it can be injected
services.AddScoped<Settings>();
services.AddScoped<Tiesse.Web.BL.TiesseWebManager>();

//i.Cookies.ApplicationCookie.ExpireTimeSpan = TimeSpan.FromDays(14);
})

services.AddMvc().AddJsonOptions(jsonOptions =>

推荐答案
我遇到了同样的问题.我解决了很久.但是几天前我找到了解决方案.正如您在评论中提到的，问题是机器密钥.我不知道为什么，但应用程序每次重新启动时都会生成新的机器密钥.所以解决问题的方法是强制应用程序使用常量键.为此，您需要在启动时添加如下代码:
I faced same issue. I couldn't solve it for a long time. But few days ago I found solution. As you mentioned in comments the problem is machine key. I don't know why, but application generates new machine key every time when it has been restarted. So way to solve problem is to force application to use constant key. To do it you need to add code like this in startup:
public void ConfigureServices(IServiceCollection services)
{
var environment = services.BuildServiceProvider().GetRequiredService<IHostingEnvironment>();
services.AddDataProtection()
.SetApplicationName($"my-app-{environment.EnvironmentName}")
.PersistKeysToFileSystem(new DirectoryInfo($@"{environment.ContentRootPath}keys"));
...
}
应用程序在key"文件夹中启动后，您将找到包含您的机器密钥的 xml.您可以在这里找到更多详细信息
After application's start in "key" folder you will find xml which contains your machine key. More details you can find here
