Hi guys, i want to setBody to handleRequest for test. How should i do?

handleRequest(<http://HttpMethod.Post|HttpMethod.Post>, "/login") {
    addHeader(HttpHeaders.ContentType, ContentType.Application.Json.toString())
    addHeader(HttpHeaders.Accept, ContentType.Application.Json.toString())
    //setBody("{\"username\": \"emirhan\", \"password\": \"1234\"}")
    setBody(listOf("username" to "emirhan", "password" to "1234").toString())
}

i'm receiving:
io.ktor.features.CannotTransformContentToTypeException: Cannot transform this request's content to com.emirhan.model.UserRequest

My data class UserRequest is like:

@Serializable
data class UserRequest(
    val username: String,
    var password: String
)

In route im receiving body like:

val userRequest = call.receive<UserRequest>()

I also try this too

setBody(Json.encodeToString(UserRequest("emirhan","1234")))

getting same error

Just log your body: Currently you produce this:

[(username, emirhan), (password, 1234)]

, but you need this:

{
  "username": "emirhan",
  "password": 1234
}

. Why do you handle serialization yourself? How do you get this body normally?

[hfhbd]

Using Json should work 🤔

[hfhbd]

Can you please add a logger to get the real body set to your server?

I'm trying this in test i add CallLogging for my test method but not logging

[Emirhan Emmez]

install(CallLogging) {
    level = <http://Level.INFO|Level.INFO>
    format {
        val status = it.response.status()
        val httpMethod = it.request.httpMethod.value
        "Status: $status, HTTP method: $httpMethod"
    }
    filter { call -> call.request.path().startsWith("/") }
}

but with FormUrlEncoded it works well. I can setBody like:

setBody(listOf("username" to "emirhan", "password" to "1234").formUrlEncode())

[hfhbd]

This test works...

@Serializable
data class A(val s: String, val p: Int)

class Testing {
    @Test
    fun a() = withTestApplication({
        install(ContentNegotiation) {
            json()
        }
        install(CallLogging)
        routing {
            get("works") {
                call.respondText("Works")
            }
            get("bam") {
                error("BAM")
            }
            post("p") {
                val body = call.receive<A>()
                println(body)
                call.respond(body)
            }
        }
    }) {
        val content = handleRequest(<http://HttpMethod.Post|HttpMethod.Post>, "p") {
            addHeader(HttpHeaders.ContentType, ContentType.Application.Json.toString())
            setBody(Json.encodeToString(A("a", 42)))
        }.response.content
        assertEquals("""{"s":"a","p":42}""", content)
    }
}

what is your ktor version?

[hfhbd]

1.6.6

[hfhbd]

plugins {
kotlin("jvm") version "1.6.0"
kotlin("plugin.serialization") version "1.6.0"
}

repositories {
mavenCentral()
}

dependencies {
implementation("io.ktorktor server cio1.6.6")
implementation("io.ktorktor serialization1.6.6")

runtimeOnly("ch.qos.logbacklogback classic1.2.7")

testImplementation(kotlin("test"))
testImplementation("io.ktorktor server test host1.6.6")
}

[Emirhan Emmez]

I'm using ktor 1.6.5 and kotlin 1.5.32 because of Koin not supporting top versions and throwing NoSuchMethod exception

[Emirhan Emmez]

Doing same as you but still getting error, maybe this is about ktor or kotlin versions

[hfhbd]

Downgrading my sample does not throw any errors 😄
Wanna try it?

So something is broken in your test/implementation

[Emirhan Emmez]

implementation("io.ktor:ktor-serialization:$ktor_version")
implementation("io.ktor:ktor-server-netty:$ktor_version")
testImplementation("io.ktor:ktor-server-tests:$ktor_version")
implementation("io.ktor:ktor-jackson:$ktor_version")

[Emirhan Emmez]

setBody(Json.encodeToString(UserRequest("emirhan", "1234")))

[Emirhan Emmez]

val userRequest = call.receive<UserRequest>()

dude i don't understand if you want to check here my repo 😂

[hfhbd]

In your testModule you don't call configureSerialization()

[hfhbd]

And BTW you should not use 2 different serialization libraries: I would remove Jackson and only use kotlinx.serialization

[Emirhan Emmez]

you are a lifesaver i'm using jackson library because of openapi library
