[Farid Benhaimoud]

Hi can anybody help me out with this. I have a KMM ktor client connected with a ktor server/backend. I can authenticate and get a token but when I call this get from client:

suspend fun courses(request: CourseRequest): CourseResponse = client.get {
        url("courses")
        parameter("courseLevel", request.courseLevel)
        headers {
            append(HttpHeaders.Authorization, sharedSettingsHelper.token)
        }
    }.body()

I get this back from log

This is my code from serverside

authenticate {
        route("courses"){
            get("{courseLevel}") {
                val params = call.parameters["courseLevel"]
                println("__PARAMS = $params")

                if (params == null) {
                    call.respond(
                        status = HttpStatusCode.BadRequest, message = AuthResponse(
                            errorMessage = "Error getting courses!"
                        )
                    )

                    return@get
                }

                val result = repository.getCourses(params.toInt())
                call.respond(
                    status = result.code, message = result.data
                )
            }
        }
    }

fun Application.configureRouting() {
    intercept(ApplicationCallPipeline.Fallback) {
        if (call.isHandled) return@intercept
        val status = call.response.status() ?: HttpStatusCode.NotFound
        call.respond(status)
    }
    routing {
        authRouting()
        courseRouting()
    }
}

Any help would be much appreciated.

Can you please state the problem?

[Farid Benhaimoud]

I dont really understand why i get a 404 response

[Aleksei Tirman [JB]]

Do you get 404 without authenticate and get("{courseLevel}") routes?

[Farid Benhaimoud]

No then it works

[Farid Benhaimoud]

Also when I use authenticate{} without the parameter in the get it works

[Farid Benhaimoud]

Nobody can help with this issue?

[Farid Benhaimoud]

It looks like call.parameters works like call.request.queryParameters
So instead of

get("/user/{courseLevel}") {
    val params = call.parameters["courseLevel"] 
        // ...
    
}

You need to use

get("/user") {. ---> without /{courseLevel}
   val params = call.parameters["courseLevel"] 
        // ...
    
}

[Aleksei Tirman [JB]]

With the get("{courseLevel}") route you need to make a request to like http://192.168.2.3:8080/courses/5 to get 200 response.
