        close in interface AutoCloseable
        Specified by:
        close in interface SdkAutoCloseable
      • clientName

        Each HTTP client implementation should return a well-formed client name that allows requests to be identifiable back to the client that made the request. The client name should include the backing implementation as well as the Sync or Async to identify the transmission type of the request. Client names should only include alphanumeric characters. Examples of well formed client names include, ApacheSync, for requests using Apache's synchronous http client or NettyNioAsync for Netty's asynchronous http client.
        Specified by:

The client name should include the backing implementation as well as the Sync or Async to identify the transmission type of the request. Client names should only include alphanumeric characters. Examples of well formed client names include, ApacheSync, for requests using Apache's synchronous http client or NettyNioAsync for Netty's asynchronous. If you prefer asynchronous programming, you can mix this recipe with Scala Futures, which are demonstrated in Chapter 13. Another option is the Dispatch library. Eurosport 2 su sky go. As its documentation states, “Dispatch is a library for asynchronous HTTP interaction. It provides a Scala vocabulary for Java’s async-http-client.”.

  • The AHC component provides HTTP based endpoints for consuming external HTTP resources (as a client to call external servers using HTTP). The component uses the Async Http Client library. Maven users will need to add the following dependency to their pom.xml for this component.
  • An asynchronous callback-based Http client for Android built on top of Apache’s HttpClient libraries. All requests are made outside of your app’s main UI thread, but any callback logic will be executed on the same thread as the callback was created using Android’s Handler message passing.

Another webapp call http-remote-app is deployed on any other server. The servlet on the http-local-app delegates requests to the async http client and returns immediately. The async http client connects to the remote app and when it recieves a response, a callback is fired which relays the message back to the original response stream.
