Identity Server 3 - 401在Ajax上调用而不是302

Question

我有一个web api/mvc混合应用程序,我已将其配置为使用cookie身份验证.这适用于应用程序的mvc部分.web api确实强制执行授权,但不返回401 - Unauthorised它,而是返回a 302 - Found并重定向到登录页面.我宁愿它返回一个401.我试图挂钩CookieAuthenticationProvider.OnApplyRedirect代理,但似乎没有调用.我错过了什么？我目前的设置如下:

AntiForgeryConfig.UniqueClaimTypeIdentifier = Constants.ClaimTypes.Subject;
JwtSecurityTokenHandler.InboundClaimTypeMap = new Dictionary<string, string>();

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AuthenticationType = "Cookies",
    ExpireTimeSpan = TimeSpan.FromMinutes(20),
    SlidingExpiration = true,
    CookieHttpOnly = true,
    CookieSecure = CookieSecureOption.Never, //local non ssl-dev only
    Provider = new CookieAuthenticationProvider
    {
        OnApplyRedirect = ctx =>
        {
            if (!IsAjaxRequest(ctx.Request))
            {
                ctx.Response.Redirect(ctx.RedirectUri);
            }
        }
    }
});

app.UseOpenIdConnectAuthentication(new OpenIdConnectAuthenticationOptions
{
    Authority = IdentityConfig.Authority,
    ClientId = IdentityConfig.SoftwareClientId,
    Scope = "openid profile roles",
    RedirectUri = IdentityConfig.RedirectUri,
    ResponseType = "id_token",
    SignInAsAuthenticationType = "Cookies"
});

Answer 1

在你的例子中,UseCookieAuthentication不再控制它,而是控制UseOpenIdConnectAuthentication它.这涉及使用Notifications属性和拦截OpenID Connect身份验证请求.

尝试以下灵感:

app.UseOpenIdConnectAuthentication(new OpenIdConnectAuthenticationOptions
{
    Authority = IdentityConfig.Authority,
    ClientId = IdentityConfig.SoftwareClientId,
    Scope = "openid profile roles",
    RedirectUri = IdentityConfig.RedirectUri,
    ResponseType = "id_token",
    SignInAsAuthenticationType = "Cookies",
    Notifications = new OpenIdConnectAuthenticationNotifications
    {
        RedirectToIdentityProvider = notification =>
        {
            if (notification.ProtocolMessage.RequestType == OpenIdConnectRequestType.AuthenticationRequest)
            {
                if (IsAjaxRequest(notification.Request) && notification.Response.StatusCode == (int)HttpStatusCode.Unauthorized)
                {
                    notification.Response.StatusCode = (int)HttpStatusCode.Unauthorized;
                    notification.HandleResponse();
                    return Task.FromResult(0);
                }
            }
            return Task.FromResult(0);
        }
    }
});
