我目前正在尝试学习如何使用持票令牌构建安全api,我不断收到此错误(InvalidOperationException：未找到名为’Bearer’的AuthorizationPolicy.)我不知道为什么.我正在使用asp.net-core 2.0并尝试使用jwt auth中间件.
这是我的启动课程,任何帮助将不胜感激！

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    const string TokenAudience = "ExampleAudience";
    const string TokenIssuer = "ExampleIssuer";
    private RsaSecurityKey key;
    private TokenAuthOptions tokenOptions;

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {

        var keyParams = RSAKeyUtils.GetRandomKey();
        key = new RsaSecurityKey(keyParams);

        tokenOptions = new TokenAuthOptions()
        {
            Audience = TokenAudience,
            Issuer = TokenIssuer,
            SigningCredentials = new SigningCredentials(key, SecurityAlgorithms.RsaSha256Signature)
        };

        services.AddDbContext<VulnerabilityContext>(options =>
            options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

        services.AddScoped<LoggingActionFilter>();
        services.AddScoped<VulnsService>();

        services.AddAuthentication(o =>
        {
            o.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
            o.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
        }).AddJwtBearer(o =>
        {
            o.Authority = "https://localhost:54302";
            o.Audience = tokenOptions.Audience;
            o.RequireHttpsMetadata = false;
        });

        services.AddMvc();
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {

        //app.UseSession();
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseBrowserLink();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        app.UseAuthentication();

        app.UseStaticFiles();

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });
    }
}

解决方法:

我没有使用策略,当我忘记在authorize属性中指出角色时,这个错误发生在我身上.

我有这个：

[Authorize("Administrator")] // if you don't specify the property name Roles it will consider it as the policy name

通过将其更改为：

[Authorize(Roles = "Administrator")]
