在两个ASP.NET Core应用程序之间共享Cookie [英] Sharing Cookies Between Two ASP.NET Core Applications

问题描述

我在两个独立的ASP.NET中使用 WsFederation 核心项目.

I'm using WsFederation in two separate ASP.NET Core projects.

每个项目在Startup.cs

services.AddAuthentication(sharedOptions =>
{
    sharedOptions.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    sharedOptions.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    sharedOptions.DefaultChallengeScheme = WsFederationDefaults.AuthenticationScheme;
})
.AddWsFederation(options =>
{
    options.Wtrealm = Configuration["Wtrealm"];
    options.MetadataAddress = "http://example.com/metadata.xml";
    options.SkipUnrecognizedRequests = true;
    options.RequireHttpsMetadata = false;
    options.UseTokenLifetime = false;
})
.AddCookie(options =>
{
    options.Cookie.Name = "MySharedCookie";
    options.Cookie.Path = "/";
    options.Cookie.Domain = ".dev.example.com";
});

我在浏览器中加载了项目#1，并且得到了我的cookie:

I load project #1 in the browser and I get my cookie:

然后，我导航到同一子域上的项目#2.但是，项目2无法识别MySharedCookie并重新进行身份验证.我得到一个同名但值不同的新Cookie:

I then navigate to project #2 on the same sub domain. However, project #2 doesn't recognize MySharedCookie and re-authenticates. I get a new cookie with the same name but a different value:

我正在ASP.NET Core中尝试做些什么吗?在ASP.NET Core中，我可以与项目#2共享项目1的cookie吗?

Is what I'm trying to do possible in ASP.NET Core? Is there a way in ASP.NET Core I can share project #1's cookie with project #2?

推荐答案

Cookie共享应用程序示例可用.

为了共享cookie，请在每个应用程序中创建一个DataProtectionProvider，并在应用程序之间使用一组公用/共享的密钥.

In order to share cookies, you create a DataProtectionProvider in each app and using a common/shared set of keys between the apps.

.AddCookie(options =>
{
    options.Cookie.Name = ".SharedCookie";
    options.Cookie.Domain = "example.com";
    options.DataProtectionProvider =
        DataProtectionProvider.Create(new DirectoryInfo("path-tokeys"));
});
