I am using IdentityServer4 with .Net Core 2.1 and Asp.Net Core Identity. I have two projects in my Solution.
- IdentityServer
- Web API
I want to Protect my Web APIs, I use postman for requesting new tokens, It works and tokens are generated successfully. When I use [Authorize] on my controllers without Roles it works perfectly but when I use [Authorize(Roles="Student")] (even with [Authorize(Policy="Student")]) it always return 403 forbidden
Whats wrong with my code
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();
}
}
Test 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)
{
}
}

app.UseIdentityServer();
//app.Run(async (context) =>
//{
// await context.Response.WriteAsync("Hello World!");
