So right now I have code that will display the from the url:
URL:
http://localhost:9080/MyWebApp/MyServlet?qty=1&item=100&desc=CD+ROMS&price=9.99&action=add&addToCart=Add+to+cart
What is shown:
Recent Queries
Item_100
And here is the code that will display that:
public String getRecentQueries(HttpServletRequest request)
{
String queries = "";
HttpSession session = request.getSession(false);
if (session != null)
{
Enumeration e = session.getAttributeNames();
if ( e.hasMoreElements() )
{
queries += "<h4>Recent Queries</h4><ul>";
}
while ( e.hasMoreElements() )
{
String name = (String) e.nextElement();
String value =
(String) session.getAttribute(name);
queries += "<li><a href=\"" + value + "\">" +
name + "</a></li>";
}
queries += "</ul></p>";
}
return queries;
}
My question is, given the values in the url, how do I get somet开发者_JS百科hing other than just 'item
'? How would I get desc
, or price
?
Try this. You need to be pulling the parameter names and values directly from the request, not the attributes from the session.
public String getRecentQueries(HttpServletRequest request)
{
String queries = "";
Enumeration e = request.getParameterNames();
if ( e.hasMoreElements() )
{
queries += "<h4>Recent Queries</h4><ul>";
}
while ( e.hasMoreElements() )
{
String name = (String) e.nextElement();
String value = (String) request.getParameter(name);
queries += "<li><a href=\"" + value + "\">" + name + "</a></li>";
}
queries += "</ul></p>";
return queries;
}
