How to get HttpServletRequest in Liferay WebService - web-services

Question

Hi I have a webService that is generated from buildServices of Liferay..
the method looks like this
public User getUserTest(long userId) {
User u = null;
try {
Token token = OAuthFactoryUtil.createToken("sasa", "sdad");
} catch (OAuthException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
u = UserLocalServiceUtil.getUser(userId);
System.out.println("xx user " + u.getScreenName());
} catch (Exception e) {
System.out.println(" Exception ************* " + e.toString());
}
return u;
}
the parameters in this ws would be this :
http://localhost:8080/demo-portlet/api/json?serviceClassName=com.sample.portlet.library.service.BookServiceUtil&serviceMethodName=getUserTest&userId=10195&serviceParameters=[userId]
having userId as a parameter..
How would you pass a parameter if you need HttpServletRequest.. my method would look like this
public User getUserTest(HttpServletRequest httpRequest) {
User u = null;
try {
String version = httpRequest.getHeader("X-PHM-APP-VERSION");
Token token = OAuthFactoryUtil.createToken("sasa", "sdad");
} catch (OAuthException e1) {
e1.printStackTrace();
}
try {
String authorization = httpRequest.getHeader("Authorization");
u = UserLocalServiceUtil.getUser(Long.valueOf(authorization));
System.out.println("authorization --> " + authorization);
System.out.println("xx user " + u.getScreenName());
} catch (Exception e) {
System.out.println(" Exception ************* " + e.toString());
}
return u;
}
I need the HttpServletRequest to get the parameters from header, instead of passing through url. Is there a better way to get parameters from header? thanks for your help

Answer 1

I think webservice layer is normally at a later stage where in you would never pass request. Ideally what you would do is pass header parameter to the webservice instead of request

Answer 2

In Liferay, you will get HttpServletRequest from the PortletRequest. Please use com.liferay.portal.util.PortalUtil class.
There are 2 methods in it. getHttpServletRequest() and getOriginalServletRequest(), you will get the both core level http request from these methods.
