Subject [jira] [Created] (CXF-7071) HttpServletRequest.getParameter only get String from query not both posted form data
Date Tue, 27 Sep 2016 13:22:20 GMT
Neal Hu created CXF-7071:
----------------------------

             Summary: HttpServletRequest.getParameter only get String from query not both
posted form data
                 Key: CXF-7071
                 URL: https://issues.apache.org/jira/browse/CXF-7071
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS
    Affects Versions: 3.1.7
            Reporter: Neal Hu
             Fix For: 3.1.8


The http request:
 POST /dubbott-demo-provider/v1.0/users/beanparam HTTP/1.1
HOST: localhost:8080
accept: text/plain
content-type: application/x-www-form-urlencoded
content-length: 12

pageIndex=99

The resource method returns null:
{code:java}
    public String beanParam(@Context HttpServletRequest req, String ak) {
        String pageIndex = req.getParameter("pageIndex")    
        return pageIndex;
    }
{code}
>From the servlet 3.1 API doc:
String javax.servlet.ServletRequest.getParameter(String name)

Returns the value of a request parameter as a String, or null if the parameter does not exist.
Request parameters are extra information sent with the request. For HTTP servlets, parameters
are contained in the query string or posted form data.

if we add below servlet filter:
{code:java}
	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
	        System.out.println(request.getParameter("pageIndex") );
		chain.doFilter(request, response);
	}
{code}
The output is "99" the response is the same "99".

As a conclusion the CXF HttpServletRequest doesn't comply the Servlet 3.1 API Spec.
