How to read the full URL from both Interceptors and Actions?

Question

If I typed url as localhost:8080/MyApp/loginAction.action?username=raj&password=123 how will I get url as it is in interceptor/action class? I tried some methods of request object but not getting. used request.getRequestURL(),request.getQueryString()....etc

You can use `param` tag which always adds parameters to the url, unfortunately you can't use it with the `form` tag. — Roman C, Sep 14 '15 at 15:33

You can use HttpServletRequest.getRequestURL() to get the full URL excluding the parameters (the "?foo=bar" part, that is called QueryString).

You can get the QueryString, if any (and without the ? sign), with HttpServletRequest.getQueryString().

In an INTERCEPTOR, getting the request from the ActionContext:

public String intercept(ActionInvocation invocation) throws Exception {     
    final ActionContext context = invocation.getInvocationContext();        
    HttpServletRequest request = (HttpServletRequest)context.get(StrutsStatics.HTTP_REQUEST);

    String url = request.getRequestURL();
    String queryString = request.getQueryString();

    String fullUrl = url + (queryString==null ? "" : ("?" + queryString));

    LOG.debug(fullUrl);

    return invocation.invoke();
}

In an ACTION, getting the request from ServletRequestAware:

public class MyAction implements ServletRequestAware {
    private javax.servlet.http.HttpServletRequest request;

    public void setServletRequest(javax.servlet.http.HttpServletRequest request){ 
        this.request = request;
    }

    public String execute(){
        String url = request.getRequestURL();
        String queryString = request.getQueryString();

        String fullUrl = url + (queryString==null ? "" : ("?" + queryString));

        LOG.debug(fullUrl);

        return Action.SUCCESS;
    }
}
