使用Bearer令牌访问IdentityServer4上受保护的API

Question

我试图搜索该问题的解决方案，但没有找到正确的搜索文本。

我的问题是，如何配置我的IdentityServer，使其也可以接受/授权带有BearerTokens的Api请求？

我已配置并正在运行IdentityServer4。我还在我的IdentityServer上配置了测试API，如下所示：

[Authorize]
[HttpGet]
public IActionResult Get()
{
    return new JsonResult(from c in User.Claims select new { c.Type, c.Value });
}

在我的startup.cs中，ConfigureServices（）如下：

public IServiceProvider ConfigureServices(IServiceCollection services)
    {
        ...
        // configure identity server with stores, keys, clients and scopes
        services.AddIdentityServer()
            .AddCertificateFromStore(Configuration.GetSection("AuthorizationSettings"), loggerFactory.CreateLogger("Startup.ConfigureServices.AddCertificateFromStore"))

            // this adds the config data from DB (clients, resources)
            .AddConfigurationStore(options =>
            {
                options.DefaultSchema = "auth";
                options.ConfigureDbContext = builder =>
                {
                    builder.UseSqlServer(databaseSettings.MsSqlConnString,
                        sql => sql.MigrationsAssembly(migrationsAssembly));
                };
            })

            // this adds the operational data from DB (codes, tokens, consents)
            .AddOperationalStore(options =>
            {
                options.DefaultSchema = "auth";
                options.ConfigureDbContext = builder =>
                    builder.UseSqlServer(databaseSettings.MsSqlConnString,
                        sql => sql.MigrationsAssembly(migrationsAssembly));

                // this enables automatic token cleanup. this is optional.
                options.EnableTokenCleanup = true;
                options.TokenCleanupInterval = 30;
            })

            // this uses Asp Net Identity for user stores
            .AddAspNetIdentity<ApplicationUser>()
            .AddProfileService<AppProfileService>()
            ;

        services.AddAuthentication(IdentityServerAuthenticationDefaults.AuthenticationScheme)
            .AddIdentityServerAuthentication(options =>
                {
                    options.Authority = authSettings.AuthorityUrl;
                    options.RequireHttpsMetadata = authSettings.RequireHttpsMetadata;
                    options.ApiName = authSettings.ResourceName;
                })

和Configure（）如下：

        // NOTE: 'UseAuthentication' is not needed, since 'UseIdentityServer' adds the authentication middleware
        // app.UseAuthentication();
        app.UseIdentityServer();

我有一个配置为允许隐式授予类型的客户端，并且将配置的ApiName包括为AllowedScopes之一：

 new Client
            {
                ClientId = "47DBAA4D-FADD-4FAD-AC76-B2267ECB7850",
                ClientName = "MyTest.Web",
                AllowedGrantTypes = GrantTypes.Implicit,

                RequireConsent = false,

                RedirectUris           = { "http://localhost:6200/assets/oidc-login-redirect.html", "http://localhost:6200/assets/silent-redirect.html" },
                PostLogoutRedirectUris = { "http://localhost:6200/?postLogout=true" },
                AllowedCorsOrigins     = { "http://localhost:6200" },

                AllowedScopes =
                {
                    IdentityServerConstants.StandardScopes.OpenId,
                    IdentityServerConstants.StandardScopes.Profile,
                    IdentityServerConstants.StandardScopes.Email,
                    "dev.api",
                    "dev.auth" // <- ApiName for IdentityServer authorization
                },
                AllowAccessTokensViaBrowser = true,
                AllowOfflineAccess = true,
                AccessTokenLifetime = 18000,
            },

当我使用Postman访问受保护的API时，即使将有效的Bearer Token添加到了Request标头中，它总是重定向到Login页面。

注释掉[Authorize]属性将正确返回响应，但是User.Claims当然是空的。

当登录到IdentityServer（通过浏览器）然后访问API（通过浏览器）时，它还将返回响应。这次，User.Claims可用。

有一个示例在IdentityServer内部共同托管受保护的API：IdentityServerAndApi

我将他们的创业公司与您的创业公司进行快速比较，是他们打电话AddJwtBearer而不是AddIdentityServerAuthentication：

services.AddAuthentication()
 .AddJwtBearer(jwt => {
    jwt.Authority = "http://localhost:5000";
    jwt.RequireHttpsMetadata = false;
    jwt.Audience = "api1";
});

该Authorize属性还设置身份验证方案：

[Authorize(AuthenticationSchemes = "Bearer")]
