c# - 无法读取请求正文 - 身份服务器回调 url

问题描述

对于我的后端，我只想允许通过“秘密”网址访问登录页面，否则只需将用户重定向到 webui 应用程序。为此，我创建了以下中间件和实现。

中间件

namespace App.Middleware
{
    public class DefaultRedirectRequest
    {
        private readonly RequestDelegate _next;
        private readonly IIdentityServerService _identityServerService;

        public DefaultRedirectRequest(RequestDelegate next, IIdentityServerService identityServerService)
        {
            _next = next;
            _identityServerService = identityServerService;
        }

    public async Task InvokeAsync(HttpContext context)
    {
        var request = context.Request;
        var response = context.Response;
        var user = context.User.Identity;

        if (!user.IsAuthenticated)
        {
            // if the Request comes from base (this App)
            if (request.Headers[HeaderNames.Origin].Count == 0)
            {
                if (request.Path.StartsWithSegments(new PathString("/secreturl")))
                {
                    await _next(context);

                    // Create url and redirect
                    response.Headers[HeaderNames.Location] = _identityServerService.CreateAuthorizeUrl();
                    response.StatusCode = StatusCodes.Status302Found;
                    response.Redirect(response.Headers[HeaderNames.Location]);
                }
                else if (request.Path.StartsWithSegments(new PathString("/signin-oidc")))
                {
                     // Sign-in..
                }
                else
                {
                    // Redirect to client app
                    response.Headers[HeaderNames.Location] = "http://localhost:5555";
                    response.StatusCode = StatusCodes.Status301MovedPermanently;

                    response.Redirect(response.Headers[HeaderNames.Location]);
                }
            }
        }
        else
        {
            await context.ChallengeAsync();
        }
    }
}

public static class DefaultRedirectRequestExtension
{
    public static IApplicationBuilder UseDefaultRedirectRequest(this IApplicationBuilder builder)
    {
        return builder.UseMiddleware<DefaultRedirectRequest>();
    }
}

}

身份服务器服务

public class IdentityServerService : IIdentityServerService
{
    public HttpClient Client { get; }

    public IdentityServerService(HttpClient client)
    {
        client.BaseAddress = new Uri("http://localhost:5000/");
        Client = client;
    }

    public string CreateAuthorizeUrl()
    {
        var request = new RequestUrl(Client.BaseAddress.AbsoluteUri + "connect/authorize");

        var url= request.CreateAuthorizeUrl(
                            clientId: "client.id",
                            responseType: "code id_token",
                            responseMode: "form_post",
                            redirectUri: "http://localhost:4444/signin-oidc",
                            state: Guid.NewGuid().ToString("N"),
                            nonce: Guid.NewGuid().ToString("N"),
                            scope: "openid profile roles offline_access");

        return url;
    }
}

启动

public void ConfigureServices(IServiceCollection services)
{
    services.AddHttpClient<IIdentityServerService, IdentityServerService>();

    services
        .AddAuthentication(options =>
        {
            options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultSignOutScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
        })
        .AddCookie(options =>
        {
            options.SlidingExpiration = true;
        })
        .AddOpenIdConnect(options =>
        {
            options.Authority = "http://localhost:5000";
            options.RequireHttpsMetadata = false;
            options.GetClaimsFromUserInfoEndpoint = true;
            options.SaveTokens = true;
            options.ClientId = "client.id";
            options.ClientSecret = "secret";
            options.ResponseType = "code id_token";

            options.Scope.Add("api1");
            options.Scope.Add("offline_access");
            options.Scope.Add("profile");
            options.Scope.Add("roles");

            options.AuthenticationMethod = OpenIdConnectRedirectBehavior.RedirectGet;
            options.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;

            options.Events.OnAuthorizationCodeReceived = async context =>
            {
                // Handle Here?
            };
            })
}
public void Configure(IApplicationBuilder app)
{
    app.UseDefaultRedirectRequest();
    app.UseAuthentication();
    // static files, mvc etc..
}

有了这个，我被重定向到所有 URL 上的客户端应用程序，除了将我引导到 idsrver 的“秘密”。所以到目前为止一切都很好。我可以登录到 idsrver 但是重定向回来时我只是在控制台中收到此错误消息

info: Microsoft.AspNetCore.Server.Kestrel[32]
      Connection id "0HLO6R5VCNBTC", Request id "0HLO6R5VCNBTC": the application completed without reading the entire request body.

它没有遇到任何断点，所以我使用 fiddler 进行进一步的调试。这是从 idsrver 返回的原始输出。

我有一个使用标准设置的分支，只需点击 [Authorize] 属性，响应看起来相似，应用程序处理响应。

所以我猜启动（或中间件？）无法解析原始请求体？我在这里想念什么？如何实施此流程？
