基本用法（Scala）

HTTP 请求是通过 WSClient 类创建的，你可以将其用作你自己的类中的注入参数。

import javax.inject.Inject

import play.api.libs.ws.WSClient

import scala.concurrent.{ExecutionContext, Future}

class MyClass @Inject() (
  wsClient: WSClient
)(implicit ec: ExecutionContext){
  
  def doGetRequest(): Future[String] = {
    wsClient
      .url("http://www.google.com")
      .get()
      .map { response =>
      // Play won't check the response status,
      // you have to do it manually
      if ((200 to 299).contains(response.status)) {
        println("We got a good response")
        // response.body returns the raw string
        // response.json could be used if you know the response is JSON
        response.body
      } else
        throw new IllegalStateException(s"We received status ${response.status}")
    }
  }
}
