ASP.NET Core 6: Difficulty with Role-based Authorization for Multiple JWT Tokens
I'm trying to implement I recently switched to I'm confused about I'm currently implementing role-based authorization in my ASP.NET Core 6 API using JWT tokens, but I'm facing issues when trying to distinguish between different user roles based on the tokens received... Specifically, I have two roles: `Admin` and `User`, and I need to restrict access to certain endpoints based on these roles. I've set up my JWT authentication in `Startup.cs` as follows: ```csharp services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme) .AddJwtBearer(options => { options.TokenValidationParameters = new TokenValidationParameters { ValidateIssuer = true, ValidateAudience = true, ValidateLifetime = true, ValidateIssuerSigningKey = true, ValidIssuer = "myIssuer", ValidAudience = "myAudience", IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("mySecretKey")) }; }); ``` In my controller, I’ve tried to use the `[Authorize]` attribute with roles specified like this: ```csharp [Authorize(Roles = "Admin")] [HttpGet("/admin/data")] public IActionResult GetAdminData() { return Ok(new { data = "This is admin data" }); } [Authorize(Roles = "User")] [HttpGet("/user/data")] public IActionResult GetUserData() { return Ok(new { data = "This is user data" }); } ``` However, when I attempt to access the `/admin/data` endpoint with a token that has the role `User`, I still get a `403 Forbidden` response, which is expected. The issue arises when I call the `/user/data` endpoint with an `Admin` token; it also returns `403 Forbidden`, and I can’t figure out why. I’ve ensured that both tokens are correctly signed and contain the appropriate role claims. I've verified that the role claims are present in the tokens by decoding them here: [jwt.io](https://jwt.io). The tokens look correct, and I can see the roles in the claims. My configuration might be missing something, or I could be misinterpreting how role authorization works in ASP.NET Core. Has anyone faced a similar issue or knows what might be going wrong here? This is part of a larger web app I'm building. Thanks in advance! The project is a mobile app built with C#. Any ideas what could be causing this? I'm on macOS using the latest version of C#. This is happening in both development and production on Ubuntu 22.04.
