【问题描述】:
使用lightbend Lagom 框架,我正在尝试连接到 Binance 的 websocket api。
但是,我在连接时不断收到以下错误:
400 普通 HTTP 请求已发送到 HTTPS 端口
是否可以从 Lagom 连接到安全的 websocket 服务?那么使用 WebSocketClient 呢? 我有以下代码:
trait BinanceStreamingService extends Service {
def depthStream(symbol: String): ServiceCall[NotUsed, Source[DepthEvent, NotUsed]]
override final def descriptor = {
import Service._
import me.koopal.crypto.api.BinanceModelsMarshallers._
named("depth-stream")
.withCalls(
restCall(GET, "/ws/:symbol@deth", depthStream _)
)
}
}
private val binanceStreamApplication = new LagomClientApplication("binance-ws") with StaticServiceLocatorComponents with AhcWSComponents {
override def staticServiceUri = URI.create("wss://stream.binance.com:9443")
}
override def stream = ServiceCall { _ =>
binanceStreamClient.depthStream("bnbbtc")
.invoke()
.map { s =>
s.runForeach(e => println(e))
}.onComplete {
case Success(x) => println("success", x)
case Failure(ex) => println("failure", ex)
}
Future.successful("test")
}
