C#-IdentityServer4管理界面

首先,我简单地创建了一个新用户并设置了密码,然后创建了名称为Api_Name的新ApiResource.然后,我创建了具有相同名称Api_Name的IdentityResource.最后,我创建了一个名称为Api_Client的新客户端,并将客户端的“允许范围”设置为Api_Name并将“允许的授予类型”设置为“密码”,最后将客户端密码设置为secret

现在,我创建了一个新的WebApi项目(Core 2.1)并在启动类中使用它

public void ConfigureServices(IServiceCollection services) {
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

        services.AddMvcCore().AddAuthorization().AddJsonFormatters();

        services.AddAuthentication("Bearer")
            .AddIdentityServerAuthentication(options => {
                options.Authority = "http://localhost:5000"; //Identity Server URL
                options.RequireHttpsMetadata = false; // make it false since we are not using https
                options.ApiName = "Api_Name"; //api name which should be registered in IdentityServer
            });
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env) {
        if (env.IsDevelopment()) {
            app.UseDeveloperExceptionPage();
        }
        else {
            app.UseHsts();
        }

        app.UseAuthentication();

        app.UseHttpsRedirection();
        app.UseMvc();
    }

并且确定我在WebApi控制器中使用了[Authorize]属性

最后,测试.
我创建了控制台应用程序并使用此代码

var identityServer = await DiscoveryClient.GetAsync("http://localhost:5000"); //discover the IdentityServer
        if (identityServer.IsError) {
            Console.Write(identityServer.Error);
            return;
        }

        HttpClient client = new HttpClient();

        var tokenResponse = await client.RequestPasswordTokenAsync(new PasswordTokenRequest {
            Address = identityServer.TokenEndpoint,
            ClientId = "Api_Client",
            ClientSecret = "secret",

            UserName = "Majd",
            Password = "P@ssw0rd@123"
        });

        if (tokenResponse.IsError) {
            Console.WriteLine(tokenResponse.Error);
            return;
        }

        //Call the API

        client.SetBearerToken(tokenResponse.AccessToken);

        var response = await client.GetAsync("https://localhost:44368/api/values");
        var response2 = await client.GetAsync("https://localhost:44368/api/values/1");
        var content = await response.Content.ReadAsStringAsync();
        Console.WriteLine(JArray.Parse(content));
        Console.ReadKey();

问题是response2返回未经授权的401.所以为什么出现此错误,因为我使用了从身份服务器接收到的访问令牌

    var tokenResponse = await client.RequestPasswordTokenAsync(new PasswordTokenRequest {
        Address = identityServer.TokenEndpoint,
        ClientId = "Api_Client",
        ClientSecret = "secret",

        UserName = "Majd",
        Password = "P@ssw0rd@123",
        Scope = "Api_Name"
    });

在IDS4中,仅针对已请求的范围颁发令牌,这与IDS3不同,在IDS3中,您将获得允许客户端的所有范围.因此,就您的Api身份验证中间件而言,由于令牌不足,因此不允许您的客户端访问它.
