clova-cek-sdk-kotlin

This is clova extension sdk for kotlin. You can use this sdk with any server-side frameworks like Spring, Armeria, etc.

This SDK contains several libraries.

• core (mandatory): The core functions of Clova extension
• data converter (optional): The json converter for Clova, it supports those json libraries
  • Jackson
• echo: The sample of clova extension based on Spring WebFlux.
• echo-mvc: The sample of clova extension based Spring MVC.

Because this SDK supports coroutines, please use Kotlin 1.1+.

Setup

Add the configurations in the build.gradle as follows.

repositories {
    jcenter()
}

dependencies {
    //Mandatory
    implementation "com.linecorp:clova-extension-core:1.1.1"

    //Optional
    implementation "com.linecorp:clova-extension-converter-jackson:1.1.1" //the data convertor for jackson
}

Getting started

To get started with the sdk, define the ClovaClient as follows

val client: ClovaClient = clovaClient("application.id") {
    objectMapper = JacksonObjectMapper() //it is must, use pre-defined object mapper (based on Jackson) or to create custom object mapper
      
    launchHandler { launchRequest, session ->
        //Add your implementation
    }

    intentHandler { intentRequest, session ->
        //Add your implementation
    }

    sessionEndedHandler { sessionEndedRequest, session ->
        //Add your implementation
    }
}

Handle the request

You just need to call handleCustomExtensionRequest in your route handler

val response = client.handleClovaRequest(requestBody, httpHeaders)

requestBody and response is the json string.

Coroutine support

You can use suspend function in the handler directly as follows.

launchHandler { launchRequest, session ->
    delay(1000)
    //implement here
}

Or if you want to handle the clova request inside coroutine scope, you can use handleClovaRequestSuspend

asyc {
    client.handleClovaRequestSuspend(requestBody, httpHeaders)
}
