Play Framework 2.1 - 找不到隐式ExecutionContext

Question

我打电话给这样的网络服务:

WS
  .url(url)
  .get
  .map { response => // error occurs on this line
    response.status match {
      case 200 => Right(response.json)
      case status => Left(s"Problem accessing api, status '$status'")
  }
}

完整的错误: Error: Cannot find an implicit ExecutionContext, either require one yourself or import ExecutionContext.Implicits.global

Answer 1

根据这个问题,它已在文档中修复.我需要添加以下导入:

import play.api.libs.concurrent.Execution.Implicits._
