Ktor 是一个使用 Kotlin 以最小的成本快速创建 Web 应用程序的框架（serato歌单导入traktor）

Ktor is a framework for quickly creating web applications in Kotlin with minimal effort.

import io.ktor.server-ty.*import io.ktor.routing.*import io.ktor.application.*import io.ktor.http.*import io.ktor.response.*import io.ktor.server.engine.*fun main(args: Array) { embeddedServer(Netty, 8080) { routing { get("/") { call.respondText("Hello, world!", ContentType.Text.Html) } } }.start(wait = true)}

Runs embedded web server on localhost:8080Installs routing and responds with Hello, world! when receiving GET http request for root path

Principles

Unopinionated

Ktor Framework doesn't impose a lot of constraints on what technology a project is going to use – logging, templating, messaging, persistent, serializing, dependency injection, etc. Sometimes it may be required to implement a simple interface, but usually it is a matter of writing a transforming or intercepting function. Features are installed into application using unified interception mechanism which allows building arbitrary pipelines.

Ktor Application can be hosted in any servlet container with Servlet 3.0+ API support such as Tomcat, or standalone using Netty or Jetty. Support for other hosts can be added through the unified hosting API.

Ktor APIs are mostly functions calls with lambdas. Thanks to Kotlin DSL capabilities, code looks declarative. Application composition is entirely developer's choice – with functions or classes, using dependency injection framework or doing it all manually in main function.

Asynchronous

Ktor pipeline machinery and API is utilising Kotlin coroutines to provide easy-to-use asynchronous programming model without making it too cumbersome. All host implementations are using asynchronous I/O facilities to avoid thread blocking.

Testable

Ktor application can be hosted in a special test environment, which emulates to some extent web server without actually doing any networking. It provides easy way to test an application without mocking too much stuff, and still achieve good performance while validating application calls. Integration tests with real embedded web server are of course possible, too.
