Question

我正在尝试在单个POST调用中将JSON映射到多个案例类

 val route = (path(HttpConstants.CreateJob) & post) {
    entity(as[JobDetailsEntity]) {
      jobDetailsEntity: JobDetailsEntity =>
      complete(createJobDetails(updatedJobDetailsEntity).map(_.asJson))
      } ~
      entity(as[JobEntity]) { jobEntity: JobEntity =>
       complete(createJob(updatedJobEntity).map(_.asJson))
     }
  }

这样做只会执行createJobDetails而不是createJob。

case class JobDetailsEntity(id:Option[Long],name:String,data:String,createDate:Long)

case class JobEntity(id:Option[Long],name:String,createDate:Long)

虽然我可以在具有不同路径路径的单独POST调用中执行此操作。如果有办法在单个REST调用中执行此操作，请帮助我。

Answer 1

使用~（或concat）concatenate 2 routes，基本上使第二个成为第一个回退，以防第一个未成功完成。

您所寻找的内容相当于将指令嵌套在一条路线中。您可以使用&（正如您在指令path和post上所做的那样）来实现此结果。

 val route = (path(HttpConstants.CreateJob) & post) {
    (entity(as[JobDetailsEntity]) & entity(as[JobEntity])) {
      (jobDetailsEntity: JobDetailsEntity, jobEntity: JobEntity) =>
      complete(...)
      }
  }

Answer 2

任何人都可以在这里提供帮助。用途如下：

post {
      entity(as[Either[JobDetailsEntity, JobEntity]]) {
        case left: Left[JobDetailsEntity, JobEntity] => doSomethingWith(left.value)
        case right: Right[JobDetailsEntity, JobEntity] => doSomethingWith(right.value)
      }
    }
