Class HttpExchange


  • public abstract class HttpExchange
extends Object
    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.

    Since:
    1.7, JAX-WS 2.2

      • getRequestHeaders

        public abstract Map<String,List<String>> getRequestHeaders​()
        Returns an immutable Map containing the HTTP headers that were included with this request. The keys in this Map will be the header names, while the values will be a List of Strings containing each value that was included (either for a header that was listed several times, or one that accepts a comma-delimited list of values on a single line). In either of these cases, the values for the header name will be presented in the order that they were included in the request.

        The keys in Map are case-insensitive.

        Returns:
        an immutable Map which can be used to access request headers

      • getRequestHeader

        public abstract String getRequestHeader​(String name)
        Returns the value of the specified request header. If the request did not include a header of the specified name, this method returns null. If there are multiple headers with the same name, this method returns the first header in the request. The header name is case-insensitive. This is a convienence method to get a header (instead of using the getRequestHeaders()).
        Parameters:
        name - the name of the request header
        Returns:
        returns the value of the requested header, or null if the request does not have a header of that name

      • getResponseHeaders

        public abstract Map<String,List<String>> getResponseHeaders​()
        Returns a mutable Map into which the HTTP response headers can be stored and which will be transmitted as part of this response. The keys in the Map will be the header names, while the values must be a List of Strings containing each value that should be included multiple times (in the order that they should be included).

        The keys in Map are case-insensitive.

        Returns:
        a mutable Map which can be used to set response headers.

      • addResponseHeader

        public abstract void addResponseHeader​(String name,
                                       String value)
        Adds a response header with the given name and value. This method allows a response header to have multiple values. This is a convenience method to add a response header(instead of using the getResponseHeaders()).
        Parameters:
        name - the name of the header
        value - the additional header value. If it contains octet string, it should be encoded according to RFC 2047 (http://www.ietf.org/rfc/rfc2047.txt)
        See Also:
        getResponseHeaders()

      • getRequestURI

        public abstract String getRequestURI​()
        Returns the part of the request's URI from the protocol name up to the query string in the first line of the HTTP request. Container doesn't decode this string.
        Returns:
        the request URI

      • getContextPath

        public abstract String getContextPath​()
        Returns the context path of all the endpoints in an application. This path is the portion of the request URI that indicates the context of the request. The context path always comes first in a request URI. The path starts with a "/" character but does not end with a "/" character. If this method returns "", the request is for default context. The container does not decode this string.

        Context path is used in computing the endpoint address. See HttpContext.getPath()

        Returns:
        context path of all the endpoints in an application
        See Also:
        HttpContext.getPath()

      • getRequestMethod

        public abstract String getRequestMethod​()
        Get the HTTP request method
        Returns:
        the request method

      • getHttpContext

        public abstract HttpContext getHttpContext​()
        Returns a HttpContext for this exchange. Container matches the request with the associated Endpoint's HttpContext
        Returns:
        the HttpContext for this exchange

      • close

        public abstract void close​()
                    throws IOException
        This must be called to end an exchange. Container takes care of closing request and response streams. This must be called so that the container can free or reuse underlying resources.
        Throws:
        IOException - if any i/o error

      • getRequestBody

        public abstract InputStream getRequestBody​()
                                    throws IOException
        Returns a stream from which the request body can be read. Multiple calls to this method will return the same stream.
        Returns:
        the stream from which the request body can be read.
        Throws:
        IOException - if any i/o error during request processing

      • getResponseBody

        public abstract OutputStream getResponseBody​()
                                      throws IOException
        Returns a stream to which the response body must be written. setStatus(int)) must be called prior to calling this method. Multiple calls to this method (for the same exchange) will return the same stream.
        Returns:
        the stream to which the response body is written
        Throws:
        IOException - if any i/o error during response processing

      • setStatus

        public abstract void setStatus​(int status)
        Sets the HTTP status code for the response.

        This method must be called prior to calling getResponseBody().

        status - the response code to send
        See Also:
        getResponseBody()

      • getRemoteAddress

        public abstract InetSocketAddress getRemoteAddress​()
        Returns the unresolved address of the remote entity invoking this request.
        Returns:
        the InetSocketAddress of the caller

      • getPathInfo

        public abstract String getPathInfo​()
        Returns the extra path information that follows the web service path but precedes the query string in the request URI and will start with a "/" character.

        This can be used for MessageContext.PATH_INFO

        Returns:
        decoded extra path information of web service. It is the path that comes after the web service path but before the query string in the request URI null if there is no extra path in the request URI
