Eodg.FirebaseAuthMiddleware

This is a simple piece of middleware you can utilize to authorize http requests via a Firebase ID Token.

Usage

1. Install the package Eodg.FirebaseAuthMiddleware into your web project.

2. In the ConfigureServices method of the Startup class add one (and only one) of the following method signatures:

   • services.AddFirebaseAdminFromFile(string firebaseAdminKeyPath)
   • services.AddFirebaseAdminFromAccessToken(string accessToken, IAccessMethod accessMethod = null)
   • services.AddFirebaseAdminFromStream(Stream stream)
   • services.AddFirebaseAdminFromComputeCredential(ComputeCredential computeCredential = null)
   • services.AddFirebaseAdminFromJson(string json)

3. In the Configure method of the Startup class, add the following at the very beginning of the method:

   • app.UseFirebaseAuthExceptionMiddleware();

4. In any controller/method (depending if you want the scope to be controller wide or only for a method) add the following attribute:

   • [Authorize(FirebaseAdminUtil.POLICY_NAME)]

5. When making a request, add the following header to the request:

   • "Authorization": "Bearer {token}" where {token} is the Firebase ID token to verify
