Unmarshalling是Akka-http内把网上可传输格式的数据转变成程序高级结构话数据的过程,比如把Json数据转换成某个自定义类型的实例。 Unmarshalling对一个A类实例到B类实例的转换是通过Unmarshaller[A,B]来实现的: trait Unmarshaller[-A, B] extends akka.http.javadsl.unmarshalling.Unmarshaller import akka.http.scaladsl.model._ import akka.http.scaladsl.server.Directives._ object Unmarshalling Unmarshalling可以直接进行Json到自定义类型之间的转换,如: val route = (path("User") & post) { entity(as[User]){ user => 下面就是本次讨论的示范源代码: Unmarshalling import akka.actor._ import akka.stream._ import akka.http.scaladsl.unmarshalling.Unmarshal
一旦写入和读取的字段数量或顺序不匹配,就会导致: 后续字段读取错位(例如把 int 当作 long 读取) 抛出 Parcel android.os.Parcel@4265a958: Unmarshalling
case Success(t) => println(s"Got response entity: ${t}") case Failure(e) => println(s"Unmarshalling case Success(t) => println(s"Got response entity: ${t}") case Failure(e) => println(s"Unmarshalling import akka.http.scaladsl.unmarshalling._ import akka.http.scaladsl.marshalling.Marshal import scala.collection.SortedMap case Success(t) => println(s"Got response entity: ${t}") case Failure(e) => println(s"Unmarshalling case Success(t) => println(s"Got response entity: ${t}") case Failure(e) => println(s"Unmarshalling
} } } } } 客户端订阅SSE的方式如下: import akka.http.scaladsl.unmarshalling.sse.EventStreamUnmarshalling akka.http.scaladsl.client.RequestBuilding.Get import akka.http.scaladsl.model.HttpMethods import akka.http.scaladsl.unmarshalling.Unmarshal system = ActorSystem() implicit val mat = ActorMaterializer() import akka.http.scaladsl.unmarshalling.sse.EventStreamUnmarshalling
catch (ClassNotFoundException var95) { throw new UnmarshalException("error unmarshalling catch (ClassNotFoundException var90) { throw new UnmarshalException("error unmarshalling catch (ClassNotFoundException var86) { throw new UnmarshalException("error unmarshalling catch (ClassNotFoundException var82) { throw new UnmarshalException("error unmarshalling catch (ClassNotFoundException var95) { throw new UnmarshalException("error unmarshalling
unmarshalling(Parcel parcel) 将一个Parcel对象写入到AVDescription对象。 (可选)根据已有的Parcel对象,可以读取到AVDescription对象,实现媒体描述信息的写入,代码示例如下: boolean result = avDescription.unmarshalling
所以对于自己的类会报ClassNotFoundException,就会出现android.os.BadParcelableException: ClassNotFoundException when unmarshalling ClassNotFoundException 就会出现android.os.BadParcelableException: ClassNotFoundException when unmarshalling
Exception ex) { logger.debug("Could not flush HierarchicalStreamWriter", ex); } } } // Unmarshalling XmlMappingException, IOException { throw new UnsupportedOperationException("XStreamMarshaller does not support unmarshalling
* A boolean flag is used to indicate whether this exception occurs during
* marshalling or unmarshalling indicates whether the exception occurs during marshalling (
* true), or unmarshalling XStream marshalling exception", ex);
} else
{
return new UnmarshallingFailureException("XStream unmarshalling
面向接口、策略模式、组合 问题: ➢ marshalling和unmarshalling方法该定义怎样的参数与返回值? ➢ 编组、解组的操作对象是请求、响应,请求、响应的内容是不同的。
在上期讨论我们提到过这种转换其实是ROW->Json->ByteString或者反方向的转换,在Akka-http里称之为Marshalling和Unmarshalling。 spray.json.DefaultJsonProtocol import akka.http.scaladsl.marshallers.sprayjson.SprayJsonSupport import akka.http.scaladsl.unmarshalling.Unmarshal spray.json.DefaultJsonProtocol import akka.http.scaladsl.marshallers.sprayjson.SprayJsonSupport import akka.http.scaladsl.unmarshalling

在项目中应保持一致,比如Golang采用的写法: // marshaling // unmarshaling // canceling // cancelation 而不是: // marshalling // unmarshalling
