IdentityServer4基于ASP.NET Core Identity的Web API角色授权

17

我正在使用IdentityServer4与.Net Core 2.1和Asp.Net Core Identity。我的解决方案中有两个项目:

  • IdentityServer
  • Web API

我想保护我的Web API,我使用postman请求新令牌,它可以成功生成令牌。当我在我的控制器上使用[Authorize]而没有角色时,它完美地运行,但是当我使用[Authorize(Roles="Student")](甚至使用[Authorize(Policy="Student")])时,它总是返回403禁止访问

我的代码哪里出了问题?

Web API startup.cs

  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)
        {
            services.AddMvcCore()
            .AddAuthorization(options => options.AddPolicy("Student", policy => policy.RequireClaim("Role", "Student")))
            .AddAuthorization(options => options.AddPolicy("Teacher", policy => policy.RequireClaim("Role", "Teacher")))
            .AddAuthorization(options => options.AddPolicy("Admin", policy => policy.RequireClaim("Role", "Admin")))
            .AddJsonFormatters();

            services.AddAuthentication("Bearer")
                .AddIdentityServerAuthentication(options =>
                {
                    options.Authority = "http://localhost:5000";
                    options.RequireHttpsMetadata = false;
                    options.ApiName = "api1";
                });
        }

        // 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();
            }
            app.UseAuthentication();
            app.UseMvc();
        }
    }

测试API:

  [Route("api/[controller]")]
    [ApiController]
    [Authorize(Roles="Student")]
    public class ValuesController : ControllerBase
    {
        // GET api/values
        [HttpGet]
        public ActionResult<IEnumerable<string>> Get()
        {
            return new string[] { "value1", "value2" };
        }

        // GET api/values/5
        [HttpGet("{id}")]
        public ActionResult<string> Get(int id)
        {
            return "value";
        }

        // POST api/values
        [HttpPost]
        public void Post([FromBody] string value)
        {
        }

        // PUT api/values/5
        [HttpPut("{id}")]
        public void Put(int id, [FromBody] string value)
        {
        }

        // DELETE api/values/5
        [HttpDelete("{id}")]
        public void Delete(int id)
        {
        }
    }

问题在于声明没有被添加到访问令牌中。
有两个令牌,即访问令牌和身份令牌。
如果您想要向身份令牌添加声明,则需要配置IdentityResource。如果您想要向访问令牌添加声明,则需要配置ApiResource(或作用域)。
这应该可以解决您的问题:
public static IEnumerable<ApiResource> GetApiResources()
{
    return new List<ApiResource>
    {
        new ApiResource("api1", "My API"),
        new ApiResource("roles", "My Roles", new[] { "role" })
    };
}

确保客户端(postman)请求roles范围。

我使用IdentityServer的示例代码进行了测试。在我的设置中,我已将角色“TestUser”添加到alice:

new TestUser
{
    SubjectId = "1",
    Username = "alice",
    Password = "password",
    Claims = new List<Claim> { new Claim("role", "TestUser") } 
},

请注意请求范围,这是邮递员的调用。

不好意思,它不起作用。我在问题中添加了 GitHub 链接,请检查。 - Mohammad Olfatmiri

在您的Api中,在services.AddAuthentication("Bearer")之前的某个位置添加一行JwtSecurityTokenHandler.InboundClaimTypeMap.Clear();
更多信息请参见此文编辑: 另外,请尝试使用roles身份资源更新身份资源配置。
    // scopes define the resources in your system
    public static IEnumerable<IdentityResource> GetIdentityResources()
    {
        return new List<IdentityResource>
        {
            new IdentityResources.OpenId(),
            new IdentityResources.Profile(),
            new IdentityResource("roles", new[] { "role" })
        };
    }

如果您的客户端AllowedScopes需要添加角色,请使用以下代码:

    AllowedScopes = { "api1", "roles" }

最后,您的Postman请求应该要求包含roles范围:scope: api1 roles
编辑2:此外,请更新您的个人资料以在发出的声明中包含角色。
    public async Task GetProfileDataAsync(ProfileDataRequestContext context)
    {
        context.IssuedClaims.AddRange(context.Subject.Claims);

        var user = await _userManager.GetUserAsync(context.Subject);

        var roles = await _userManager.GetRolesAsync(user);

        foreach (var role in roles)
        {
            context.IssuedClaims.Add(new Claim(JwtClaimTypes.Role, role));
        }
    }

上面的内容可能需要更新,只有在请求时才添加“roles”声明。确保新发出的JWT令牌现在包括像下面这样的“roles”声明:

谢谢,我添加了JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();但没有起作用... - Mohammad Olfatmiri
@Oli 好的,您能分享一下idsrv4生成的标记的示例(就像您第一个截图中的那个,但是是明文)。另外,您可以尝试仅保留[Authorize]属性,您说这个方法有效,然后在调试器中检查ClaimsPrincipal以查看实际存在哪些声明。 - Vidmantas Blazevicius
啊,好的,这很有道理,我觉得我们快要解决了。你能在Postman请求中将“roles”添加到请求范围内吗?应该是“api1 roles”。 - Vidmantas Blazevicius
我添加了角色,但仍然无法正常工作。代码、令牌和最后的图片已更新,请查看一下。谢谢。 - Mohammad Olfatmiri
你能否在Postman请求中将openid添加到请求范围,以便它具有api1 openid roles?并将openid添加到客户端的AllowedScopes中。 - Vidmantas Blazevicius

我通过在ApiClaims表的Type列中添加role来解决了这个问题,请参见下面的图片。
ApiClaims表中找到的ApiResourceId列名是ApiResources表的主键,其列名为Identer image description here

截至今天,实际上这就是所需的全部内容。您可以将声明类型放在 ApiClaims 表中,使其对 API 的所有范围全局可用,或者将其添加到 API 的特定范围并在 ApiScopeClaims 表下创建它。 - John C
