Firebase authentication with ASP.NET Core sample

The project defines one controller called SampleController with two endpoints:

• /api/sample/public: accessible without any authentication
• /api/sample/protected: only accessible if a correct OAuth token is provided

We can access the public endpoint with a simple GET request without any token:

GET http://localhost:5000/api/sample/public HTTP/1.1

And we get

HTTP/1.1 200 OK

However, if we try to reach the second endpoint without a token:

GET http://localhost:5000/api/sample/protected HTTP/1.1

We get

HTTP/1.1 401 Unauthorized

In order to access the protected endpoint, we need to provide the OAuth token in the Authorization header:

GET http://localhost:5000/api/sample/protected HTTP/1.1
Authorization: Bearer [OAUTH_TOKEN]
