Extension Attribute to Azure Functions v2, that allows to obrain ClaimsPrincipal on every request. Currently supports key load from Azure B2C by jwks_uri and simple JsonWebKey. Pluggable on Azyre Function Startup

The extension allows you to use custom tokens in Azure Functions v2.

Step 1.

1. Add the nuget AzureExtensions.FunctionToken
2. Add to StartUp file:

           builder.AddAzureFunctionsToken(new TokenSinginingKeyOptions()
            {
                SigningKey = new JsonWebKey("your key"),
                Audience = "your audience",
                Issuer = "your issuer"
            });

OR

            builder.AddAzureFunctionsToken(new TokenAzureB2COptions()
            {
                //AzureB2CSingingKeyUri = new Uri("https://yourapp.b2clogin.com/yourapp.onmicrosoft.com/discovery/v2.0/keys?p=yourapp-policy"),
                Audience = "your audience",
                Issuer = "your issuer"
            });

3. Add it to Azure Function:

    public class Example
    {
        [FunctionName("Example")]
        public async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", Route = null)] HttpRequest req,
            [FunctionToken] FunctionTokenResult token,
            ILogger log)
        {
            log.LogInformation("C# HTTP trigger function processed a request.");
            return (ActionResult) new OkObjectResult($"Hello, {token}");
        }
    }

4. That's it. See examples for the details.
