Exercise4

Module 5: Hosting Services On-Premises and in Azure

Lab: Implement an Azure Function

Para este lab utilizamos Azure Functions Core Tools si no las tienes instaladas

npm i -g azure-functions-core-tools@core --unsafe-perm true

---

En este lab creamos una azure function en local con las Azure Tools.

Modificamos el código de la función para que haga una llamada al Post del ejercccio 2

(añade viajeros al vuelo)

y la publicampos en Azure

---

Creamos un proyecto de funciones

func init BlueYonder.Flights.GroupProxy -n --worker-runtime dotnet

Creamos la funcion con el trigger HttpTrigger

La probamos

nada nuevo

añadimos la clase Travellers.cs y modificamos la función con el código sigiente

nota debemos tener hecha el ejercicio 2 y funcionando https://blueyonder-flights-jrdf.azurewebsites.net/api/Flights

    {
        [FunctionName("BookFlightFunc")]
        public static  IActionResult  Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            log.LogInformation("C# HTTP trigger function processed a request to the flights booking service.");

            var flightId = req.Query["flightId"];

            var flightServiceUrl = $"http://blueyonder-flights-jrdf.azurewebsites.net/api/flights/bookFlight?flightId={flightId}";

            log.LogInformation($"Flights service url:{flightServiceUrl}");

            var travelers = new List<Traveler>
            {
                new Traveler { Email = "204837Dazure@gmail.com" , FirstName = "Jonathan", LastName = "James", MobilePhone = "+61 0658748", Passport = "204837DCBA" },
                new Traveler { Email = "204837Dfunction@gmail.com", FirstName = "James", LastName = "Barkal", MobilePhone = "+61 0658355", Passport = "204837DCBABC" }
            };

            var travelersAsJson = JsonConvert.SerializeObject(travelers);

            using (var client = new HttpClient())
            {
                client.PostAsync(flightServiceUrl,
                                 new StringContent(travelersAsJson,
                                                   Encoding.UTF8,
                                                   "application/json")).Wait();
            }

            return (ActionResult)new OkObjectResult($"Request to book flight was sent successfully");
        }
    }
}

la volvemos a ejectuar con func host start --build

Todo correcto

creamos una funcion app con la siguiente configuracion

publicamos (primero az login)

y probamos
