Examples of HttpExchange

com.facebook.presto.jdbc.internal.jetty.client.HttpExchange
com.sun.net.httpserver.HttpExchange
This class encapsulates a HTTP request received and a response to be generated in one exchange. It provides methods for examining the request from the client, and for building and sending the response.
The typical life-cycle of a HttpExchange is shown in the sequence below.
1. {@link #getRequestMethod()} to determine the command
2. {@link #getRequestHeaders()} to examine the request headers (if needed)
3. {@link #getRequestBody()} returns a {@link java.io.InputStream} for reading the request body.After reading the request body, the stream is close.
4. {@link #getResponseHeaders()} to set any response headers, except content-length
5. {@link #sendResponseHeaders(int,long)} to send the response headers. Must be called beforenext step.
6. {@link #getResponseBody()} to get a {@link java.io.OutputStream} to send the response body.When the response body has been written, the stream must be closed to terminate the exchange.
Terminating exchanges
Exchanges are terminated when both the request InputStream and response OutputStream are closed. Closing the OutputStream, implicitly closes the InputStream (if it is not already closed). However, it is recommended to consume all the data from the InputStream before closing it. The convenience method {@link #close()} does all of these tasks.Closing an exchange without consuming all of the request body is not an error but may make the underlying TCP connection unusable for following exchanges. The effect of failing to terminate an exchange is undefined, but will typically result in resources failing to be freed/reused. @since 1.6
javax.xml.ws.spi.http.HttpExchange
This class encapsulates a HTTP request received and a response to be generated in one exchange. It provides methods for examining the request from the client, and for building and sending the response.
A HttpExchange must be closed to free or reuse underlying resources. The effect of failing to close an exchange is undefined. @author Jitendra Kotamraju @since JAX-WS 2.2
org.apache.camel.component.http.HttpExchange
Represents a HTTP exchange which exposes the underlying HTTP abtractions via {@link #getRequest()} and {@link #getResponse()} @version $Revision: 563665 $
org.apache.http.nio.protocol.HttpAsyncClientProtocolHandler.HttpExchange
org.apache.http.nio.protocol.HttpAsyncServiceHandler.HttpExchange
org.eclipse.jetty.client.HttpExchange
org.mortbay.jetty.client.HttpExchange
An HTTP client API that encapsulates Exchange with a HTTP server. This object encapsulates:
- The HTTP server. (see {@link #setAddress(InetSocketAddress)} or {@link #setURL(String)})
- The HTTP request method, URI and HTTP version (see {@link #setMethod(String)}, {@link #setURI(String)}, and {@link #setVersion(int)}
- The Request headers (see {@link #addRequestHeader(String,String)} or {@link #setRequestHeader(String,String)})
- The Request content (see {@link #setRequestContent(Buffer)} or {@link #setRequestContentSource(InputStream)})
- The status of the exchange (see {@link #getStatus()})
- Callbacks to handle state changes (see the onXxx methods such as {@link #onRequestComplete()} or {@link #onResponseComplete()})
- The ability to intercept callbacks (see {@link #setEventListener(HttpEventListener)}
The HttpExchange class is intended to be used by a developer wishing to have close asynchronous interaction with the the exchange. Typically a developer will extend the HttpExchange class with a derived class that implements some or all of the onXxx callbacks. There are also some predefined HttpExchange subtypes that can be used as a basis (see {@link ContentExchange} and {@link CachedExchange}.
Typically the HttpExchange is passed to a the {@link HttpClient#send(HttpExchange)} method, which inturn selects a {@link HttpDestination} and calls it's {@link HttpDestination#send(HttpExchange), which}then creates or selects a {@link HttpConnection} and calls its {@link HttpConnection#send(HttpExchange).A developer may wish to directly call send on the destination or connection if they wish to bypass some handling provided (eg Cookie handling in the HttpDestination).
In some circumstances, the HttpClient or HttpDestination may wish to retry a HttpExchange (eg. failed pipeline request, authentication retry or redirection). In such cases, the HttpClient and/or HttpDestination may insert their own HttpExchangeListener to intercept and filter the call backs intended for the HttpExchange.} @author gregw @author Guillaume Nodet
