Getting request attributes in freemarker

Question

How do I check a value from the request attribute in freemarker? I tried <#if *${RequestParameters['servicesettings']} ??> but getting errors ->

Encountered "*" at line

Can anyone help?

Answer 1

It depends on the Web application framework, because FreeMarker itself doesn't expose the request parameters. (Well, except if the framework uses freemareker.ext.servlet.FreemarkerServlet which is kind of an extension to FreeMarker.) Also, usually you shouldn't access request parameters directly from an MVC template, or anything that is HTTP/Servlet specific.

As of the error message, what you have written has a few syntax errors... probably you meant <#if RequestParameters.servicesettings??> (it's not JSP - don't use ${...}-s inside FreeMarker tags). This will require that you have RequestParameters in the data-model, that I can't know for sure...

We should write like this:

${Request.requestattribute}
