Asynchronous API to to query web services, as an http client.
Usage example:
class MyService @Inject() (ws: WSClient) {
ws.url("http://example.com/feed").get()
ws.url("http://example.com/item").post("content")
}
When greater flexibility is needed, you can also create clients explicitly and pass them into WS:
import play.api.libs.ws._
import play.api.libs.ws.ahc._
import akka.stream.Materializer
import play.api.ApplicationLifecycle
import javax.inject.Inject
import scala.concurrent.Future
class MyService @Inject() (lifecycle: ApplicationLifecycle)(implicit mat: Materializer) {
private val client = new AhcWSClient(new AhcConfigBuilder().build())
client.url("http://example.com/feed").get()
lifecycle.addStopHook(() =>
// Make sure you close the client after use, otherwise you'll leak threads and connections
client.close()
Future.successful(())
}
}
Or call the client directly:
import com.typesafe.config.ConfigFactory
import play.api.libs.ws._
import play.api.libs.ws.ahc._
val configuration = play.api.Configuration(ConfigFactory.parseString(
"""
|play.ws.ssl.trustManager = ...
""".stripMargin))
val parser = new DefaultWSConfigParser(configuration, app.classloader)
val builder = new AhcConfigBuilder(parser.parse())
val secureClient: WSClient = new AhcWSClient(builder.build())
val response = secureClient.url("https://secure.com").get()
secureClient.close() // must explicitly manage lifecycle
The value returned is a Future[WSResponse], and you should use Play's asynchronous mechanisms to use this response.
