Allowing Multiple Roles in Ocelot Routes

In the world of web application development, managing user access can be a daunting task. Ocelot, a popular API Gateway, streamlines this process but can present challenges when it comes to allowing multiple user roles access to specific routes. If you're looking to enable both "Premium" and "Regular" users to access the same route, you might wonder what the best approach is to make this happen.

The Traditional Approach

Under typical circumstances, if you want to restrict a route to a single role, you would set up your ocelot.global.json file like this:

This configuration translates into a straightforward check where only "Premium" users can access the designated route. But what if you want to extend access to additional roles? This is where the challenge arises.

Solution: Custom Middleware in Ocelot

To allow multiple roles to access a route, you can override the default Ocelot middleware. Below, we'll break down the steps you need to follow to accomplish this.

Step 1: Override Default Authorization Middleware

Begin by overriding the default AuthorizationMiddleware in your Startup.cs configuration file. You'll need to create a custom middleware that can handle multiple roles. Here’s how to do it:

Step 2: Create the Custom Middleware

Next, you'll write a custom middleware class. This middleware will check if the incoming request has a valid JWT token and determine if the role matches any of the allowed roles. Here’s a sample implementation:

Setting Multiple Roles in Your Configuration

After implementing the above snippets, you can now set your RouteClaimsRequirement in ocelot.global.json to allow multiple roles:

With this configuration, Ocelot will now check for either "Regular" or "Premium" roles in the user's cookies and grant access accordingly.

Conclusion

By cleverly leveraging Ocelot’s middleware capabilities, you can easily allow multiple roles to access the same route within your API. This not only simplifies the role management process but also enhances the user experience by giving access to various user types without complicating your routing logic.

Implementing these steps ensures that both "Regular" and "Premium" users can enjoy the same services without unnecessary roadblocks.
