Subject [jira] [Updated] (CXF-7071) HttpServletRequest.getParameter only get String from query not both posted form data
Date Wed, 29 Mar 2017 17:04:41 GMT

     [ https://issues.apache.org/jira/browse/CXF-7071?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Neal Hu updated CXF-7071:
-------------------------

Yes, usually we will not use request object directly. But some time we need pass request in
order to instance other object such as Apache oltu. Inside its construct method the form parameter
will be evaluated.

>             Project: CXF
>          Issue Type: Bug
>          Components: JAX-RS
>    Affects Versions: 3.1.7
>            Reporter: Neal Hu
>            Assignee: Sergey Beryozkin
>             Fix For: 3.1.8, 3.0.11, 3.2.0

>
> 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.
