hi I am trying to do a redirect like this (using

ktor-server-resources

)

suspend fun ApplicationCall.redirect(resource: Any) {
    val path = application.href(resource)
    respondRedirect(path)
}

And here is the file where redirect is used

const val PHRASES = "/phrases"

@Serializable
@Resource(PHRASES)
class Phrases

fun Route.phrases(db: Repository) {
    authenticate("auth") {
        get<Phrases> {
            val user = call.authentication.principal as User
            val phrases = db.phrases().toTypedArray()
            call.respond(
                FreeMarkerContent(
                    "phrases.ftl",
                    mapOf("phrases" to phrases, "displayName" to user.displayName)
                )
            )
        }

        post<Phrases> {
            val params = call.receiveParameters()
            val action = params["action"] ?: throw IllegalArgumentException("Missing parameter: action")
            when(action) {
                "delete" -> {
                    val id = params["id"] ?: throw IllegalArgumentException("Missing parameter: id")
                    db.remove(id)
                }
                "add" -> {
                    val emoji = params["emoji"] ?: throw IllegalArgumentException("Missing parameter: emoji")
                    val phrase = params["phrase"] ?: throw IllegalArgumentException("Missing parameter: phrase")
                    db.add(EmojiPhrase(emoji, phrase))
                }
            }
            call.redirect(Phrases)
        }
    }
}

Initial page loads fine But on redirect it fails on browser console I see this 405 error Now I am not sure what is wrong here Update Actually on further checking its

POST

method which is not working I am not sure what's wrong when I simply use

post(StringUrl)

it works but when

server-resources

it does not work Solved It was the issue of imports, I used the

<http://server.routing.post|server.routing.post>

instead of

<http://server.resources.post|server.resources.post>

When using

server-resources

plugin in ktor, one needs to use HTTP methods from

server.resources

package and not from

server.routing

package Thanks @Aleksei Tirman [JB] helping me here

Firstly, the

kotlinx.serialization

framework cannot serialize objects of

Any

type so you need to have a refied type parameter in the

redirect

method:

suspend inline fun <reified T: Any> ApplicationCall.redirect(resource: T) {
    val path = application.href(resource)
    respondRedirect(path)
}

Secondly, you have to instantiate your resource in the POST route to make a redirect:

post<Phrases> {
    // ...
    call.redirect(Phrases())
}

I have fixed these things But POST method errors still persists

Could you please share your imports (

import

statements) ?

here is whole file

Please replace

import <http://io.ktor.server.routing.post|io.ktor.server.routing.post>

with

import <http://io.ktor.server.resources.post|io.ktor.server.resources.post>

It worked thanks. I was under the impression Post method of routing will handle the resources
