zio-http (ZIO2.x)应用程序没有从Scala 3开始

Question

我有一个简单的应用程序：

import zhttp.http.*
import zhttp.http.Method.GET
import zhttp.service.Server
import zio.*
object HexAppApplication extends ZIOAppDefault {

  // Create HTTP route
  val app: HttpApp[Any, Nothing] = Http.collect[Request] {
    case GET -> !! / "text" => Response.text("Hello World!")
    case GET -> !! / "json" => Response.json("""{"greetings": "Hello World!"}""")
  }

  val program: URIO[Any, ExitCode] = Server.start(8090, app).exitCode

  override def run: URIO[Any, ExitCode] = program

}

服务器立即启动并停止。为什么不继续启动呢？

build.sbt

val zioVersion = "2.0.0-RC5"
val zioHttpVersion = "2.0.0-RC6"

libraryDependencies += "dev.zio" %% "zio" % zioVersion
libraryDependencies ++= Seq(
  "dev.zio" %% "zio-test"          % zioVersion % "test",
  "dev.zio" %% "zio-test-sbt"      % zioVersion % "test",
  "dev.zio" %% "zio-test-magnolia" % zioVersion % "test" // optional
)
testFrameworks += new TestFramework("zio.test.sbt.ZTestFramework")

libraryDependencies += "io.d11" %% "zhttp"      % zioHttpVersion
libraryDependencies += "io.d11" %% "zhttp-test" % zioHttpVersion % Test

文档中的示例(对于Scala2.x)看起来类似：

import zio._
import zhttp.http._
import zhttp.service.Server

object HelloWorld extends App {
  val app = Http.collect[Request] {
    case Method.GET -> !! / "text" => Response.text("Hello World!")
  }

  override def run(args: List[String]): URIO[zio.ZEnv, ExitCode] =
    Server.start(8090, app).exitCode
}

Answer 1

尝试将zioHttpVersion更新为"2.0.0-RC7“。帮我修好了。

Answer 2

问题似乎是zio-http是在v2.0.0-RC6版本中针对zio构建的，因此它还不能用于最终的2.0.0或v2.0.0-RC6 版本下面的任何东西。对新的最终zio发行版的支持刚刚合并，所以没有人应该再次进入到github 按下的链接中。
