根据请求更改OWIN Auth Middleware(多租户,每个租户的oauth API密钥)

Question

我有一个多租户应用程序.每个租户都可以使用OAUTH-2与Facebook,Twitter,Google等对其用户进行身份验证.每个租户都有自己的API密钥用于上述服务.

设置OWIN管道的典型方法是在"启动"中"使用"auth提供程序,但这会在应用程序启动时设置API密钥.我需要能够为每个请求更改每个oauth API使用的密钥.

        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            Provider = cookieAuthProvider,
            CookieName = "VarsityAuth",
        });

        app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

        app.UseMicrosoftAccountAuthentication(
            clientId: "lkjhlkjkl",
            clientSecret: "kjhjkk");

我需要能够根据租户更改每个请求的这些设置.我怎样才能做到这一点？

编辑 - 我现在可以确认此解决方案对我有用.

我正在为我自己的项目调查此问题,该项目需要根据请求的主机名或第一个文件夹段支持多租户,具体取决于配置.

我还没有对此进行测试,但我认为在启动时类似这样的代码可能会做到这一点:

例如,我想为每个租户使用不同的auth cokie名称,我认为启动时的代码可能会起作用:

// for first folder segment represents the tenant
app.Map("/branch1", app1 =>
{
    app1.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
        LoginPath = new PathString("/Account/Login"),
        Provider = new CookieAuthenticationProvider
       {
            OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<SiteUserManager, SiteUser>(
            validateInterval: TimeSpan.FromMinutes(30),
            regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
    },

        CookieName = "branch1-app"
    });

});

// for when the host name of the request identifies the tenant
app.MapWhen(IsDomain1, app2 =>
{
    app2.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
        LoginPath = new PathString("/Account/Login"),
        Provider = new CookieAuthenticationProvider
        {
            OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<SiteUserManager, SiteUser>(
            validateInterval: TimeSpan.FromMinutes(30),
            regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
        },

        CookieName = "domain1-app"
    });

});

private bool IsDomain1(IOwinContext context)
{
    return (context.Request.Host.Value == "domain1");
}
