Ktor依赖性

Question

就上下文而言，我对Kotlin和Ktor都很陌生。

这是Application.kt文件。问题是安装、位置、身份验证、ContentNegotiation。即使添加了它们的maven依赖项，我也无法导入它们。

下面添加了pom.xml文件。

import com.userTodo.auth.JwtService
import com.userTodo.auth.MySession
import com.userTodo.auth.hash
import com.userTodo.repository.DatabaseFactory
import com.userTodo.repository.TodoRepository
import com.userTodo.repository.UserRepository
import com.userTodo.routes.todos
import com.userTodo.routes.users
import io.ktor.http.*
import io.ktor.server.application.*
import io.ktor.server.response.*
import io.ktor.server.request.*
import io.ktor.server.routing.*
import io.ktor.server.auth.*
import io.ktor.server.auth.jwt.*


fun main(args: Array<String>): Unit = io.ktor.server.netty.EngineMain.main(args)

fun Application.module() {
    install(Locations) {
    }

    DatabaseFactory.init()
    val userDb = UserRepository()
    val todoDb = TodoRepository()
    val jwt = JwtService()
    val hashFunction = {s:String -> hash(s)}

    install(Sessions) {
        cookie<MySession>("MY_SESSION") {
            cookie.extensions["SameSite"] = "lax"
        }
    }

    install(Authentication) {
        jwt("jwt") {

        }
    }

    install(ContentNegotiation) {
        json()
    }


    routing {
        users(userDb,todoDb,jwt,hashFunction)
        todos(todoDb,userDb)
    }
}

const val API_VERSION = "/v1"

在过去的几个小时里，我一直在努力修复这个问题，彻底搜索网页，这是我最后的选择。

Answer 1

ktor-server-content-negotiation-jvm文件中缺少ContentNegotiation插件的依赖项pom.xml。Locations插件的工件名称必须有一个平台后缀，例如ktor-server-locations-jvm。Authentication插件可以很好地使用pom.xml文件导入。
