Interface HttpMessageContext

  • All Known Implementing Classes:
    HttpMessageContextWrapper


    public interface HttpMessageContext
    HttpMessageContext contains all of the per-request state information and encapsulates the client request, server response, container handler for authentication callbacks, and the subject representing the caller.
    • Method Detail

      • isProtected

        boolean isProtected​()
        Checks if the currently requested resource is protected or not. A protected resource is a resource (e.g. a Servlet, JSF page, JSP page etc) for which a constraint has been defined in e.g. web.xml.
        Returns:
        true if a protected resource was requested, false if a public resource was requested.
      • isAuthenticationRequest

        boolean isAuthenticationRequest​()
        Checks if the current call to an authentication mechanism is the result from the application calling SecurityContext.authenticate(HttpServletRequest, HttpServletResponse, AuthenticationParameters)

        If SecurityContext#authenticate was not called, the authentication mechanism may have been invoked by the container at the start of a request.

        Returns:
        true if SecurityContext#authenticate was called, false if not.
      • isRegisterSession

        boolean isRegisterSession​()
        Check if the runtime has been asked to register an authentication session duing the current request.
        Returns:
        true if code has asked to register an authentication session, false otherwise.
      • setRegisterSession

        void setRegisterSession​(java.lang.String callerName,
                                java.util.Set<java.lang.String> groups)
        Asks the runtime to register an authentication session. This will automatically remember the logged-in status as long as the current HTTP session remains valid. Without this being asked, a HttpAuthenticationMechanism has to manually re-authenticate with the runtime at the start of each request.
        Parameters:
        callerName - the caller name for which authentication should be be remembered
        groups - the groups for which authentication should be remembered.
      • getAuthParameters

        AuthenticationParameters getAuthParameters​()
        Returns the parameters that were provided with the SecurityContext#authenticate(AuthParameters) call.
        Returns:
        the parameters that were provided with the SecurityContext#authenticate(AuthParameters) call, or a default instance. Never null.
      • getHandler

        javax.security.auth.callback.CallbackHandler getHandler​()
        Returns the low level JSR 196 handler that the runtime provided when creating this HttpMessageContext, and which this context uses to communicate the authentication details to the runtime.

        Note: This is a low level object that most higher level code would not need to use directly.

        Returns:
        the handler that the runtime provided to this context
      • getMessageInfo

        MessageInfo getMessageInfo​()
        Returns the the low level JSR 196 message info instance for the current request.

        Note: This is a low level object that most higher level code would not need to use directly.

        Returns:
        the message info instance for the current request.
      • getClientSubject

        javax.security.auth.Subject getClientSubject​()
        Returns the subject for which authentication is to take place.

        Note: This is a low level object that most higher level code would not need to use directly.

        Returns:
        the subject for which authentication is to take place.
      • getRequest

        HttpServletRequest getRequest​()
        Returns the request object associated with the current request.
        Returns:
        the request object associated with the current request.
      • setRequest

        void setRequest​(HttpServletRequest request)
        Sets the request object.
        Parameters:
        request - the request object to be set
      • withRequest

        HttpMessageContext withRequest​(HttpServletRequest request)
        Sets the request object.
        Parameters:
        request - the request object to be set.
        Returns:
        the HttpMessageContext instance on which this method was called, useful for fluent style call call chains.
      • getResponse

        HttpServletResponse getResponse​()
        Returns the response object associated with the current request.
        Returns:
        the response object associated with the current request.
      • setResponse

        void setResponse​(HttpServletResponse response)
        Set the response object.
        Parameters:
        response - the response object to be set.
      • notifyContainerAboutLogin

        AuthenticationStatus notifyContainerAboutLogin​(java.lang.String callername,
                                                       java.util.Set<java.lang.String> groups)
        Asks the container to register the given caller name and groups in order to make them available to the application for use with SecurityContext.isCallerInRole(String) etc.

        Note that after this call returned, the authenticated identity will not be immediately active. This will only take place (should no errors occur) after the authentication mechanism in which this call takes place returns control back to the container (runtime).

        As a convenience this method returns SUCCESS, so this method can be used in one fluent return statement from an HttpAuthenticationMechanism

        Parameters:
        callername - the caller name that will become the caller principal
        groups - the groups associated with the caller principal
        Returns:
        AuthenticationStatus.SUCCESS
      • notifyContainerAboutLogin

        AuthenticationStatus notifyContainerAboutLogin​(java.security.Principal principal,
                                                       java.util.Set<java.lang.String> groups)
        Asks the container to register the given caller principal and groups in order to make them available to the application for use with SecurityContext.isCallerInRole(String) etc.

        Note that this call may result in the container establishing two caller principals to represent the caller's identity -- the Principal provided here as the principal parameter, and a second principal used as the container's representation of the caller identity. A second principal is added only if the container uses a different Principal type to represent the caller. If the types are the same, only one Principal is added.

        If a second principal is added, the value returned by Principal.getName() will be the same for both principals.

        When two principals are added, the container's caller principal is returned from SecurityContext.getCallerPrincipal(), and the principal supplied here as a parameter can be retrieved using SecurityContext.getPrincipalsByType(Class). When only one is added, it is returned by SecurityContext.getCallerPrincipal().

        Note that after this call returned, the authenticated identity will not be immediately active. This will only take place (should no errors occur) after the authentication mechanism in which this call takes place returns control back to the container (runtime).

        As a convenience this method returns SUCCESS, so this method can be used in one fluent return statement from an HttpAuthenticationMechanism

        Parameters:
        principal - the Principal that will become the caller principal
        groups - the groups associated with the caller principal
        Returns:
        AuthenticationStatus.SUCCESS
      • doNothing

        AuthenticationStatus doNothing​()
        Instructs the container to "do nothing".

        When intending to do nothing, a JSR 375 authentication mechanism has to indicate this explicitly via its return value.

        As a convenience this method returns NOT_DONE, so this method can be used in one fluent return statement from an HttpAuthenticationMechanism

        Returns:
        AuthenticationStatus.NOT_DONE
      • getCallerPrincipal

        java.security.Principal getCallerPrincipal​()
        Gets the Principal set by a call to notifyContainerAboutLogin().
        Returns:
        The caller principal
      • getGroups

        java.util.Set<java.lang.String> getGroups​()
        Gets the groups set by a call to notifyContainerAboutLogin().
        Returns:
        The groups
