Question

我一直在开发多个应用程序，这些应用程序使用Identity Server 4（IDS4）进行OIDC身份验证。一切正常，直到我使用SSL卸载将应用程序置于代理之后。

目标是能够访问一个站点。当您请求登录时，应该将您重定向到IDS4验证您，然后将您发送回去。这是标准的。

真正发生的事情。 403错误：

An unhandled exception occurred while processing the request.
HttpRequestException: Response status code does not indicate success: 403 (Forbidden).

出于好奇，我关闭了IDS应用程序，并尝试通过其他应用程序之一访问它，并获得了完全相同的错误响应。这使我相信，这与使用openidc或IIS设置时应用程序中的代码有关。

注意事项：我正在使用IIS。我的代理站点上有受信任的CA证书。假设IDS正在运行，我可以在浏览器中访问“ https://ids.com/.well-known/openid-configuration”。您不会，这是一个假域名。

我尝试过的事情：

尝试从以下位置切换RequireHttpsMetadata 从假到真，
app.UseForwardedHeaders（）;

好的，我在这里肯定是错的，但是我认为问题是我的应用程序（使用OIDC时）没有发送SSL信息，从而阻止了他们访问“ https://ids.com/.well-know”地址。

我应该从哪里开始尝试？

我的一些启动代码：

    services.Configure<ForwardedHeadersOptions>(options =>
            {
                options.ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto;
                options.RequireHeaderSymmetry = false;
                options.KnownNetworks.Clear();
                options.KnownProxies.Clear();

            });

    .AddOpenIdConnect(AuthorizationConsts.OidcAuthenticationScheme, options =>
     {

         options.SignInScheme = "Cookies";
         options.Authority = "https://ids.com";
         options.RequireHttpsMetadata = true;
         options.ClientId = AuthorizationConsts.OidcClientId;


         options.Scope.Clear();
         options.Scope.Add(AuthorizationConsts.ScopeOpenId);
         options.Scope.Add(AuthorizationConsts.ScopeProfile);
         options.Scope.Add(AuthorizationConsts.ScopeEmail);
         options.Scope.Add(AuthorizationConsts.ScopeRoles);



         options.SaveTokens = true;

         options.TokenValidationParameters = new TokenValidationParameters
         {
             NameClaimType = JwtClaimTypes.Name,
             RoleClaimType = JwtClaimTypes.Role,
         };

         options.Events = new OpenIdConnectEvents
         {
             OnMessageReceived = OnMessageReceived,
             OnRedirectToIdentityProvider = OnRedirectToIdentityProvider

         };
     });

..............


    app.Use(async (Context, next) =>
           {
               if (!string.IsNullOrEmpty(Context.Request.Headers["X-ARR-SSL"]))
               {
                   Context.Request.Scheme = "https";
                   await next.Invoke();

               }
               else
               {
                   Context.Request.Scheme = "http";
                   await next.Invoke();
               }

           });

            app.UseForwardedHeaders();

            // Ensures we can serve static-files that should not be processed by ASP.NET
            app.UseStaticFiles();

            // Enable the authentication middleware so we can protect access to controllers and/or actions
            app.UseAuthentication();

Answer 1

我终于解决了这个问题。我知道它与证书有关，但是我不确定该怎么做。

我的解决方法是将options.BackchannelHttpHandler添加到

private readonly HttpClientHandler _handler;

public Startup(IHostingEnvironment env, IConfiguration config,
    ILoggerFactory loggerFactory)
    {
        _env = env;
        _config = config;
        _loggerFactory = loggerFactory;
        Configuration = config;
        _handler = new HttpClientHandler();

        _handler.ClientCertificates.Add(FindClientCertificate());//same x509cert2 that proxy server uses
        _handler.AllowAutoRedirect = true;




    }
.....


AddOpenIdConnect( scheme, options => {
....
options.BackchannelHttpHandler = _handler;
...
}

Answer 2

对我来说，添加该问题即可解决

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12

Answer 3

花了一个不眠之夜来解决这个问题。下面的代码解决了我的问题。

服务 .AddIdentityServer（选项=> {

                options.IssuerUri = <Authority Url>; //<== Added this one 
                options.Events.RaiseSuccessEvents = true;
                options.Events.RaiseFailureEvents = true;
                options.Events.RaiseErrorEvents = true;
            })
