gson

Gson

Sample project for Ktor demonstrating content negotiation feature using Gson.

Running

Run this project with:

./gradlew :gson:run

Use the following command scripts for testing:

curl -v --compress --header "Accept: application/json" http://localhost:8080/v1

Should respond with something like:

{
  "name": "root",
  "items": [
    {
      "key": "A",
      "value": "Apache"
    },
    {
      "key": "B",
      "value": "Bing"
    }
  ],
  "date": {
    "year": 2018,
    "month": 3,
    "day": 2
  }
}

The result is pretty printed, to show off how to configure gson, but it is possible to use the default gson as well

Another test:

curl -v --compress --header "Accept: application/json" http://localhost:8080/v1/item/A

Response:

{
  "key": "A",
  "value": "Apache"
}
