Class Request

  • All Implemented Interfaces:
    javax.servlet.http.HttpServletRequest, javax.servlet.ServletRequest

    public class Request
    extends java.lang.Object
    implements javax.servlet.http.HttpServletRequest
    Jetty Request.

    Implements HttpServletRequest from the javax.servlet.http package.

    The standard interface of mostly getters, is extended with setters so that the request is mutable by the handlers that it is passed to. This allows the request object to be as lightweight as possible and not actually implement any significant behavior. For example

    • The getContextPath() method will return null, until the request has been passed to a ContextHandler which matches the getPathInfo() with a context path and calls setContextPath(String) as a result.
    • the HTTP session methods will all return null sessions until such time as a request has been passed to a SessionHandler which checks for session cookies and enables the ability to create new sessions.
    • The getServletPath() method will return null until the request has been passed to a org.eclipse.jetty.servlet.ServletHandler and the pathInfo matched against the servlet URL patterns and setServletPath(String) called as a result.

    A request instance is created for each connection accepted by the server and recycled for each HTTP request received via that connection. An effort is made to avoid reparsing headers and cookies that are likely to be the same for requests from the same connection.

    Request instances are recycled, which combined with badly written asynchronous applications can result in calls on requests that have been reset. The code is written in a style to avoid NPE and ISE when such calls are made, as this has often proved generate exceptions that distraction from debugging such bad asynchronous applications. Instead, request methods attempt to not fail when called in an illegal state, so that hopefully the bad application will proceed to a major state event (eg calling AsyncContext.onComplete) which has better asynchronous guards, true atomic state and better failure behaviour that will assist in debugging.

    The form content that a request can process is limited to protect from Denial of Service attacks. The size in bytes is limited by ContextHandler.getMaxFormContentSize() or if there is no context then the "org.eclipse.jetty.server.Request.maxFormContentSize" Server attribute. The number of parameters keys is limited by ContextHandler.getMaxFormKeys() or if there is no context then the "org.eclipse.jetty.server.Request.maxFormKeys" Server attribute.

    If IOExceptions or timeouts occur while reading form parameters, these are thrown as unchecked Exceptions: ether RuntimeIOException, BadMessageException or RuntimeException as appropriate.

      • getBaseRequest

        public static Request getBaseRequest​(javax.servlet.ServletRequest request)
        Obtain the base Request instance of a ServletRequest, by coercion, unwrapping or special attribute.
        Parameters:
        request - The request
        Returns:
        the base Request instance of a ServletRequest.

        public boolean isPushSupported()
      • getPushBuilder

        public PushBuilder getPushBuilder()
        Get a PushBuilder associated with this request initialized as follows:
        • The method is initialized to "GET"
        • The headers from this request are copied to the Builder, except for:
          • Conditional headers (eg. If-Modified-Since)
          • Range headers
          • Expect headers
          • Authorization headers
          • Referrer headers
        • If the request was Authenticated, an Authorization header will be set with a container generated token that will result in equivalent Authorization
        • The query string from getQueryString()
        • The getRequestedSessionId() value, unless at the time of the call getSession(boolean) has previously been called to create a new HttpSession, in which case the new session ID will be used as the PushBuilders requested session ID.
        • The source of the requested session id will be the same as for this request
        • The builders Referer header will be set to getRequestURL() plus any getQueryString()
        • If HttpServletResponse.addCookie(Cookie) has been called on the associated response, then a corresponding Cookie header will be added to the PushBuilder, unless the Cookie.getMaxAge() is <=0, in which case the Cookie will be removed from the builder.
        • If this request has has the conditional headers If-Modified-Since or If-None-Match then the PushBuilderImpl.isConditional() header is set to true.

        Each call to getPushBuilder() will return a new instance of a PushBuilder based off this Request. Any mutations to the returned PushBuilder are not reflected on future returns.

        Returns:
        A new PushBuilder or null if push is not supported

        public java.lang.Object getAttribute​(java.lang.String name)
        Get Request Attribute.

        Also supports jetty specific attributes to gain access to Jetty APIs:

        org.eclipse.jetty.server.Server
        The Jetty Server instance
        org.eclipse.jetty.server.HttpChannel
        The HttpChannel for this request
        org.eclipse.jetty.server.HttpConnection
        The HttpConnection or null if another transport is used
        While these attributes may look like security problems, they are exposing nothing that is not already available via reflection from a Request instance.
