Setting request parameter from interceptor and accessing in ActionClass

[Jigar Naik]

Hi,

I am setting parameters from my custom interceptor, and trying to access from my ActionClass but i am not able to get the parameter in My Action Class.

	/**
 	* Google Ads
	*/
	public String intercept(ActionInvocation invocation) throws Exception {
		final ActionContext context = invocation.getInvocationContext();
		HttpServletRequest request = (HttpServletRequest) context.get(HTTP_REQUEST);
	
		HttpSession session = request.getSession(true);
			
		Map<String,Object> parameters = (Map<String,Object>)context.get(ActionContext.PARAMETERS);
		
		User user = (User)session.getAttribute("user");
		parameters.put("loginId", user.getLoginId());
	
		context.put(ActionContext.PARAMETERS,parameters );
		
		return invocation.invoke();
	}

I think they are action parameter not request parameters.

Can i set request parameters from interceptors ?

Yes, using the request object.

but there is no no method for setting request parameter. such as request.setParameter(..,..); I can setAttribute only.

In general it will almost always be quicker to do the research yourself.

(Hmm, that might be an immutable map though.)

Why do you want to do this, anyway? In general, S2 tries to remove dependencies on the request.

Well, my requirement is as below..

I have my personal website,
in which i am trying to display google ads based on the content of the page.
And few pages requres authentication.
So i have created one super user for google ads,
and when the client user logs in, google user will also login with its username/password.
and will try to read the loginId of the client user from query string(requestParameters)
and google will get the same content which client user got,
and based on the content google ads will get displayed on client user's page.

Oh. I don't see any reason to (a) do that in an interceptor, or (b) modify any request parameters.

Oh then how will google user get the id of currently logged in user
