使用 Identity Server 3 我正在尝试按照文档配置 CORS 。当我执行GET请求时，我可以看到 Fiddler 中捕获的响应是正确的并且缺少 Access-Control-Allow-Origin 标头。

这是用于设置的代码IdentityServerOptions：

public void Configuration(IAppBuilder app)
{
    var factory = InMemoryFactory.Create(
        clients: Clients.Get(),
        scopes: Scopes.Get());

    var viewOptions = new DefaultViewServiceOptions();
    viewOptions.Stylesheets.Add("/Content/site.css");
    viewOptions.Scripts.Add("/Content/logon.js");
    viewOptions.CacheViews = false;
    factory.ConfigureDefaultViewService(viewOptions);

    // This is where the CORS policy service is configured.
    var corsPolicyService = new DefaultCorsPolicyService();
    corsPolicyService.AllowAll = true;
    factory.CorsPolicyService = new Registration<ICorsPolicyService>(corsPolicyService);

    var userService = new LocalRegistrationUserService();
    factory.UserService = new Registration<IUserService>(resolver => userService);

    var options = new IdentityServerOptions
    {
        SiteName = "IdentityServer",
        SigningCertificate = this.certificateProvider.Certificate,
        Factory = factory,
        RequireSsl = true,

        // This is deprecated, but should still work according to the documentation.
        // However using or not using it makes no change.
        // CorsPolicy = CorsPolicy.AllowAll,

        ProtocolLogoutUrls = logoutUrls,
        AuthenticationOptions = new AuthenticationOptions()
        {
            EnableSignOutPrompt = false,
            EnablePostSignOutAutoRedirect = true,
            PostSignOutAutoRedirectDelay = 5,                     
        },   
    };

    app.Map("/core", idsrvApp =>
    {
        idsrvApp.UseIdentityServer(options);
    });
}

如果我然后GET从不同的站点发出一个简单的请求，这就是我得到的响应：

HTTP/1.1 302 Found
Content-Length: 0
Location: https://federation.example.com/core/login?signin=2ce0b4f...71313af
Server: Microsoft-IIS/8.5
Set-Cookie: SignInMessage.2ce0b4f...A1D5NkPJQ; path=/core; secure; HttpOnly
X-Powered-By: ASP.NET

为什么没有应用 Access-Control-Allow-Origin 标头？

似乎在 Identity Server 3 中正确设置了 CORS 策略服务，但所请求的路径显然不能通过其他服务器获得。

由日志表中的错误标识的请求路径是：

对路径提出的 CORS 请求：/connect/authorize from origin: null 但由于 CORS 路径无效而被拒绝

我相信这是作为一种额外的安全措施来防止恶意系统在未经用户同意的情况下登录用户。

因此，唯一可以调用此受保护路径的系统将在工厂中定义Client.RedirectUris（对于隐式流）。
