Authenticate user token in the backend service

To validate that user token is valid in the backend service.

Setup variables:

• IssuerUrl points to the platform oauth server
• App Id is the registered application id of the client

var IssuerUrl = "https://login.mike-cloud.com" 
var allowAudiences = new List<string> { "<App id>"};

for non production environments the issuer url is

var IssuerUrl = $"https://login.mike-cloud-{environment.ToString().ToLower()}.com";

Add authentication in the ConfigureServices initialization

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
    .AddJwtBearer(options =>
    {
        options.Authority = IssuerUrl;
        options.TokenValidationParameters = new TokenValidationParameters
        {
            ValidateIssuer = true,
            ValidAudiences = allowAudiences
        };
    });
