1 添加 apiscope
2 添加 apiresource
添加api名为“client_credentials_apis”的apiresource，并把作用域“client_credentials_apis.IdentityUserController.scope”和“client_credentials_apis.WeatherForecastController.scope”添加到该apiresource中
3 在 ids 添加客户端
添加客户端，添加客户端密钥，设置授权类型（比如 客户端凭证方式），并至少设置一个 自定义的 apiscope（如添加 client_credentials_apis.WeatherForecastController.scope）；token类型默认为 jwt。
4 客户端获取 token并使用 该token访问api资源
接下来给客户端添加 client_credentials_apis.IdentityUserController.scope ，重新访问结果如下：
再给客户端添加 client_credentials_apis.WeatherForecastController.scope，重新访问结果如下
客户端添加作用域如下图：
5 相关代码
5.1 api资源端代码如下：
配置如下：
namespace Resources_Https
{
public class Config
{
/// <summary>
/// identity server 地址
/// </summary>
public const string IdentityServerUri = "https://localhost:44310";
/// <summary>
/// reference tokens 的 clientId
/// </summary>
public const string ApiName = "client_credentials_apis";
/// <summary>
/// reference tokens 的 clientSecret
/// </summary>
public const string ApiSecret = "123456";
}
}
startup.cs 代码如下：
using IdentityModel.AspNetCore.OAuth2Introspection;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.OpenApi.Models;
namespace Resources_Https
{
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
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)
{
// nuget 安装 Microsoft.AspNetCore.Authentication.JwtBearer
// jwt tokens
services.AddAuthentication(OAuth2IntrospectionDefaults.AuthenticationScheme)
.AddJwtBearer("Bearer", options =>
{
options.Authority = Config.IdentityServerUri;
// 设置 https
options.RequireHttpsMetadata = true;
options.Audience = Config.ApiName;
});
//// reference tokens
//services.AddAuthentication("Introspection")
//.AddOAuth2Introspection("Introspection", options =>
//{
// options.Authority = Config.IdentityServerUri;
// // this maps to the API resource name and secret
// options.ClientId = Config.ApiName; // api 名
// options.ClientSecret = Config.ApiSecret; // 配置的 api 秘钥
//});
// 策略授权
services.AddAuthorization(options =>
{
// client allowedscope 包含 client_credentials_apis.WeatherForecastController.scope 才能访问
options.AddPolicy("WeatherForecastController",
policy => policy.RequireScope("client_credentials_apis.WeatherForecastController.scope")
);
options.AddPolicy("IdentityUserController",
policy => policy.RequireScope("client_credentials_apis.IdentityUserController.scope")
);
});
services.AddControllers();
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new OpenApiInfo { Title = "Resources_Https", Version = "v1" });
});
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseSwagger();
app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "Resources_Https v1"));
}
app.UseHttpsRedirection();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
}
TestController代码：
[ApiController]
[Route("[controller]/[action]")]
[Authorize]
public class TestController : ControllerBase
{
public IActionResult Ping()
{
return new JsonResult(new { code = 0, msg = "TestController pong" });
}
}
IdentityUserController 代码：
[ApiController]
[Route("[controller]/[action]")]
[Authorize(Policy = "IdentityUserController")]
public class IdentityUserController : ControllerBase
{
[HttpGet]
public IActionResult Ping()
{
return new JsonResult(new { code = 0, msg = "IdentityUserController pong" });
}
[HttpGet]
public IActionResult GetClaims()
{
var claims = User.Claims.ToList();
var id = User.Identity as ClaimsIdentity;
var claim = id.FindFirst(JwtClaimTypes.Subject);
return new JsonResult(claims);
}
}
WeatherForecastController 代码：
[ApiController]
[Route("[controller]/[action]")]
[Authorize(Policy = "WeatherForecastController")]
public class WeatherForecastController : ControllerBase
{
[HttpGet]
public IActionResult Ping()
{
return new JsonResult(new { code = 0, msg = "WeatherForecastController pong" });
}
}
5.2 客户端代码
配置代码：
public class Config
{
/// <summary>
/// identity server 地址
/// </summary>
public const string IdentityServerUri = "https://localhost:44310";
/// <summary>
/// 受保护的api地址
/// </summary>
public const string ResourceUri = "https://localhost:6001";
public const string ClientId = "ClientCredentials_1_ClientId";
public const string ClientSecret = "511536EF-F270-4058-80CA-1C89C192F69A";
public const string GrantType = "client_credentials";
}
获取token和访问资源代码：
/// <summary>
/// 使用 HttpClient 通过客户端凭证方式获取token与资源
/// 适用场景：一般用于服务端应用与服务端应用交互
/// 请求token链接格式：{idsServer}/connect/token?client_id={}&client_secret={}&grant_type=client_credentials
/// </summary>
public class HttpClient_ClientCredentials
{
public static void Run()
{
// 先获取 access token
var token_res = string.Empty;
string postData = $"client_id={Config.ClientId}&client_secret={Config.ClientSecret}&grant_type={Config.GrantType}";
using (var httpClient = new HttpClient())
{
using (HttpContent httpContent = new StreamContent(new MemoryStream(Encoding.UTF8.GetBytes(postData))))
{
httpContent.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
token_res = httpClient.PostAsync($"{Config.IdentityServerUri}/connect/token", httpContent).Result.Content.ReadAsStringAsync().Result;
}
}
// 使用 token 访问资源
if (!string.IsNullOrEmpty(token_res)){
using(HttpClient getClient = new HttpClient())
{
getClient.DefaultRequestHeaders.Add("Authorization", "Bearer " + JObject.Parse(token_res)["access_token"].ToString());
// 有token就能访问
var apiRes1 = getClient.GetStringAsync($"{Config.ResourceUri}/Test/Ping").Result;
// 有token就能访问且 client allowedscope 包含 client_credentials_apis.IdentityUserController.scope 才能访问
var apiRes2 = getClient.GetStringAsync($"{Config.ResourceUri}/IdentityUser/Ping").Result;
// 有token就能访问且 client allowedscope 包含 client_credentials_apis.WeatherForecastController.scope 才能访问
var res_res3 = getClient.GetStringAsync($"{Config.ResourceUri}/WeatherForecast/Ping").Result;
}
}
}
}
