将 Asp.Net Core 1 转换为 Core 2 后 Jwt 不工作

Question

Jwt-Rsa-Hmac 身份验证 在 this web site with this 仓库中有一个示例代码。
我一直在尝试将它从 Asp.Net Core 1 转换为 Asp.Net Core 2.
我创建了一个新的 Asp.Net Cor 2.1 项目，在搜索了它需要的更改之后，我想出了 this 代码。
它确实创建了令牌，但是在使用令牌时我总是得到 401 (unauthorized).
已经几天了，没有成功...
如果有人能帮助我，我将不胜感激。
这是我的创业公司 class：

 public class Startup
    {
        public Startup(IHostingEnvironment env)
        {
            var builder = new ConfigurationBuilder()
                .SetBasePath(env.ContentRootPath)
                .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
                .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
                .AddEnvironmentVariables();
            Configuration = builder.Build();
        }
        public IConfigurationRoot Configuration { get; }

        public void ConfigureServices(IServiceCollection services)
        {
            services.Configure<JwtSettings>(Configuration.GetSection("jwt"));
            var x = services.AddSingleton<IJwtHandler, JwtHandler>();

            var sp = services.BuildServiceProvider();
            var jwtHandler = sp.GetService<IJwtHandler>();
            services.AddAuthentication(options =>
            {
                options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
                options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
            }).AddJwtBearer(options =>
            {
                options.TokenValidationParameters = jwtHandler.Parameters;
            });
            services.AddMvc();

        }
        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
            app.UseDeveloperExceptionPage();
            loggerFactory.AddConsole(Configuration.GetSection("Logging"));
            loggerFactory.AddDebug();
            app.UseAuthentication();
            app.UseMvc();
        }

其余示例代码在 this 存储库中。

我在 .netcore2.1 中使用了这个设置并为我工作：

services.AddAuthentication(options =>
            {
                options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
                options.DefaultSignInScheme = JwtBearerDefaults.AuthenticationScheme;
                options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
            }).AddJwtBearer(cfg =>
            {
                cfg.SaveToken = true;
                cfg.TokenValidationParameters = new TokenValidationParameters
                {
                    ValidIssuer = Configuration["BearerTokens:Issuer"],
                    ValidAudience = Configuration["BearerTokens:Audience"],
                    IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["BearerTokens:Key"])),

                    ValidateIssuer = true,
                    ValidateAudience = true,
                    ValidateLifetime = true,
                    ValidateIssuerSigningKey = true,
                };

            });

Answer 2

您的示例存储库中的问题是，您正在创建新的 JwtBearerOptions here。

我改成了这个，效果很好

services.AddAuthentication(o =>
{
    o.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
    o.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
    o.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
}).AddJwtBearer(o =>
{

    o.IncludeErrorDetails = true;
    o.RequireHttpsMetadata = false;
    o.TokenValidationParameters = jwtHandler.Parameters;
    o.Events = new JwtBearerEvents()
    {
        OnAuthenticationFailed = c =>
        {
            c.NoResult();

            c.Response.StatusCode = 401;
            c.Response.ContentType = "text/plain";

            return c.Response.WriteAsync(c.Exception.ToString());
        }

    };
});
