Grpc and Rest Api service

This simple app demonstrates how to create a gRPC and REST API service in a single ASP.NET Core application. The gRPC service is implemented using the WeatherForecast service and the REST API service is implemented using the WeatherForecastController.

Build and run the sample

To run the stack:

docker-compose build
docker-compose up

Build grpc-server image:

docker build -t grpc-server . 

Run the docker container:

docker run -p 4999:4999 -p 5000:5000 --name grpc-server-container grpc-server

After the application runs, navigate to http://localhost:4999/swagger in your web browser to access the Swagger UI. Expand "WeatherForecast" accordion and click on "Try it out" -> "Execute" and it should return something similar like this below:

{
  "forecasts": [
    {
      "date": {
        "seconds": 1719418653,
        "nanos": 113660700
      },
      "temperatureC": 19,
      "temperatureF": 0,
      "summary": "Chilly"
    },
    {
      "date": {
        "seconds": 1719505053,
        "nanos": 114087500
      },
      "temperatureC": -5,
      "temperatureF": 0,
      "summary": "Mild"
    },
    {
      "date": {
        "seconds": 1719591453,
        "nanos": 114088500
      },
      "temperatureC": 22,
      "temperatureF": 0,
      "summary": "Balmy"
    },
    {
      "date": {
        "seconds": 1719677853,
        "nanos": 114088600
      },
      "temperatureC": -10,
      "temperatureF": 0,
      "summary": "Hot"
    }
  ]
}

You can also test your gRPC service by expanding "/v1/WeatherForecast" accordion and click on "Try it out" -> "Execute". It should retrun similiar result as above. Call in this case is made using HTTP/1.1 protocol.

For the gRPC piece which uses HTTP/2.0 protocol, you can use Postman (https://www.postman.com/). Create new gRPC request in Postman and import the weatherForecast.proto file to the client and enter the server address as grpc://localhost:5000.
