Question

我是 Kotlin 和 Ktor 的新手，下面的内容在启动时工作正常，现在我需要添加更多 Routes 如何我可以将路由拆分为多个文件吗？

import org.jetbrains.ktor.application.*
import org.jetbrains.ktor.features.*

fun Application.module() {
    install(DefaultHeaders)
    install(CallLogging)
    install(Routing) {
        get("/") {
            call.respondText("""
            My Example Blog2
                <form action="/contact-us" method="post">

                </form>
            """, ContentType.Text.Html)
        }
        post("/contact-us") {
            val post = call.receive<ValuesMap>() 
            SimpleEmail().apply {
                setHostName("smtp.gmail.com")
                setSmtpPort(465)
                setAuthenticator(DefaultAuthenticator("my_alias@gmail.com", "my_gmil_passoword"))
                setSSLOnConnect(true)
                setFrom("my_alias@gmail.com")
                setSubject(post["subject"])        
                setMsg(post["message"])            
                addTo("my_alias@gmail.com")
            }.send() // will throw email-exception if something is wrong
            call.respondRedirect("/contact-us/success")
        }
        get("/contact-us/success") { 
            call.respondText("Your message was sent", ContentType.Text.Html) 
        }
    }
}

fun main(args: Array<String>) {
    embeddedServer(Netty, 8080, watchPaths = listOf("BlogAppKt"), module = Application::module).start()
}

终于我明白了:

为您需要的函数名称安装路由，例如:

install(Routing) {
        contact()
}

创建一个类似 fun Route.contact(){ ..} 的函数来处理必要条件，因此对于我的示例，我创建了以下内容:

fun Route.contact(){
        get("/") {
            call.respondText("""
            My Example Blog 12
                <form action="/contact-us" method="post">
                    <input name="subject" placeholder="Subject">
                    <br>
                    <textarea name="message" placeholder="Your message ..."></textarea>
                    <br>
                    <button>Submit</button>
                </form>
            """, ContentType.Text.Html)
        }
        post("/contact-us") {
            val post = call.receive<ValuesMap>() // val userId = registration["userId"]
            SimpleEmail().apply {
                setHostName("smtp.gmail.com")
                setSmtpPort(465)
                setAuthenticator(DefaultAuthenticator("my_alias@gmail.com", "my_gmil_passoword"))
                setSSLOnConnect(true)
                setFrom("my_alias@gmail.com")
                setSubject(post["subject"])        
                setMsg(post["message"])            
                addTo("my_alias@gmail.com")
            }.send() // will throw email-exception if something is wrong
            call.respondRedirect("/contact-us/success")
        }
        get"/contact-us/success") { 
            call.respondText("Your message was sent", ContentType.Text.Html) 
        }
}
