Neal Hu commented on CXF-7071:
------------------------------
Or do you have a case where a POST request can have either HTTP query or form
payload ?－－>Yes, the request either has the form payload or query for the same
resource. So we need make our resource class like:
{code:java}
@POST
@Path("beanparam")
@Produces(MediaType.TEXT_PLAIN)
@Consumes({MediaType.APPLICATION_FORM_URLENCODED,
MediaType.APPLICATION_JSON})
@ApiOperation(value = "beanParam")
String beanParam(@BeanParam TalkListParam param, @Context
HttpServletRequest req, @HeaderParam(value = "ak") String ak);
public class TalkListParam {
@QueryParam(value = "pageIndex")
private Integer currentPage;
@FormParam(value = "pageIndex")
@ApiParam(value = "页码-ios", required = false, defaultValue = "1")
private Integer currentPageIOS=1;
｝
{code}
But if we use the servlet api, we can simply get the data via
request.getParameter("pageIndex"), now if the inputsteam parsed by cxf will not
follow the servlet api spec.
> 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.
