Interface Request

    • Method Detail

      • getSession

        Session getSession​(boolean create)
        Gets the Session. If create is false and the session has not be created previously, returns null. Also, if the session is invalidated and create is false, returns null. Invoking this method with true, when the session exists but has been invalidated, will force the creation of a new session.
        Parameters:
        create - true to force the creation of the session
        Returns:
        the session (or null if create is false the session has not been previously created)

      • getContextPath

        String getContextPath()
        Deprecated.
        in 5.4, inject the value for symbol SymbolConstants.CONTEXT_PATH instead
        Returns the context path. This always starts with a "/" character and does not end with one, with the exception of servlets in the root context, which return the empty string.

      • getParameter

        String getParameter​(String name)
        Returns the query parameter value for the given name. Returns null if no such parameter is in the request. For a multi-valued parameter, returns just the first value.

      • getParameters

        String[] getParameters​(String name)
        Returns the parameter values for the given name. Returns null if no such parameter is in the request.

      • getPath

        String getPath()
        Returns the path portion of the request, which starts with a "/" and contains everything up to the start of the query parameters. It doesn't include the context path.

      • getLocale

        Locale getLocale()
        Returns the locale of the client as determined from the request headers.

      • getDateHeader

        long getDateHeader​(String name)
        Returns the value of the specified request header as a long value that represents a Date object. Use this method with headers that contain dates, such as If-Modified-Since . The date is returned as the number of milliseconds since January 1, 1970 GMT. The header name is case insensitive. If the request did not have a header of the specified name, this method returns -1. If the header can't be converted to a date, the method throws an IllegalArgumentException.
        Parameters:
        name - a String specifying the name of the header
        Returns:
        a long value representing the date specified in the header expressed as the number of milliseconds since January 1, 1970 GMT, or -1 if the named header was not included with the reqest
        Throws:
        IllegalArgumentException - If the header value can't be converted to a date

      • getHeader

        String getHeader​(String name)
        Returns the named header as a string, or null if not found.

      • isXHR

        boolean isXHR()
        Returns true if the request originated on the client using XmlHttpRequest (the core of any Ajax behavior). Ajax action requests may behave quite differently than ordinary, page-based requests. This implementation currently depends on the client side setting a header: X-Requested-With=XMLHttpRequest (this is what Prototype does).
        Returns:
        true if the request has an XmlHttpRequest origin

      • isSecure

        boolean isSecure()
        Returns a boolean indicating whether this request was made using a secure channel, such as HTTPS.
        Returns:
        a boolean indicating if the request was made using a secure channel

      • getServerName

        String getServerName()
        Returns the host name of the server to which the request was sent. It is the value of the part before ":" in the Host header, if any, or the resolved server name, or the server IP address.
        Returns:
        the name of the server

      • isRequestedSessionIdValid

        boolean isRequestedSessionIdValid()
        Checks whether the requested session ID is still valid.
        Returns:
        true if the request included a session id that is still active, false if the included session id has expired

      • getAttribute

        Object getAttribute​(String name)
        Returns the value of the named attribute as an Object, or null if no attribute of the given name exists. Because this method is a wrapper around ServletRequest.getAttribute(String), it is case sensitive (unlike most of Tapestry).
        Parameters:
        name - a String specifying the name of the attribute
        Returns:
        an Object containing the value of the attribute, or null if the attribute does not exist

      • setAttribute

        void setAttribute​(String name,
                  Object value)
        Stores an attribute in this request. Attributes are reset between requests (and remember that in Tapestry, there is usually two requests per operation: the action request that redirects to a render request).
        Parameters:
        name - a String specifying the name of the attribute
        value - the Object to be stored, or null to remove the attribute

      • getMethod

        String getMethod()
        Returns the name of the HTTP method with which this request was made, for example, GET, POST, or PUT.
        Returns:
        a string specifying the name of the method with which this request was made

      • getLocalPort

        int getLocalPort()
        Returns the Internet Protocol (IP) port number of the interface on which the request was received.
        Returns:
        an integer specifying the port number
        Since:
        5.2.0

      • getServerPort

        int getServerPort()
        Returns the port number to which the request was sent. It is the value of the part after ":" in the Host header, if any, or the server port where the client connection was accepted on.
        Returns:
        an integer specifying the port number
        Since:
        5.2.5

      • getRemoteHost

        String getRemoteHost()
        Returns the fully qualified name of the client or the last proxy that sent the request. If the engine cannot or chooses not to resolve the hostname (to improve performance), this method returns the dotted-string form of the IP address.
        Returns:
        a String containing the fully qualified name of the client
        Since:
        5.3

      • isSessionInvalidated

        boolean isSessionInvalidated()
        Returns true if the request specified a session, and that session has been invalidated.
        Returns:
        true if session was invalidated during this request
        Since:
        5.4
