如何在 ASP.NET Core 中的子域之间共享会话?

问题描述

我有一个网站，其中包含 ali.sarahah.com 等子域，但如果用户从 www.sarahah.com 登录，则会转到 ali.sarahah.com 会话未保存.搜索后，我在 Startup.cs 中添加了以下内容:

I have a website which has subdomains such as ali.sarahah.com but if a user logs in from www.sarahah.com then goes to ali.sarahah.com the session is not saved. After searching I added the following in Startup.cs:

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    CookieDomain = ".sarahah.com"
});

我发现 .AspNetCore.Identity.Application cookie 域仍然显示子域而不是域，并且会话问题仍然存在.

I found out that .AspNetCore.Identity.Application cookie domain is still showing the subdomain and not the the domain and that session problem is still there.

我做错了吗?

推荐答案

我可以通过将这个添加到 Startup.cs 中的 ConfigureServices 方法来解决它:

I was able to solve it by adding this to ConfigureServices method in Startup.cs:

        services.AddIdentity<ApplicationUser, IdentityRole>(options =>
        {
            options.Cookies.ApplicationCookie.CookieDomain = ".yourdomain.com";
            options.Cookies.ApplicationCookie.CookieSecure = Microsoft.AspNetCore.Http.CookieSecurePolicy.None;
        })

CookieSecure 部分是因为我的网站在不同页面中的 http 和 https 之间移动.

The CookieSecure part is because my site moves between http and https in different pages.

谢谢你:)
