在Jersey中无法获取POST请求的有效负载

Question

I need to recover the whole payload of a form POST request, to send it back to the receiver (PayPal requires this as a verification procedure). I tried several ways but I always get the same warning, with no payload:

Warning:   A servlet request to the URI http://localhost:8080/ipnlistener contains form parameters in the request body but the request body has been consumed by the servlet or a servlet filter accessing the request parameters. Only resource methods using @FormParam will work as expected. Resource methods consuming the request body by other means will not work as expected.

Here's the code of the listener

@POST
@Path("/ipnlistener")
public Response testIpn(String t) {  
   System.out.println(t);
   return Response.ok().build();
}

I tried to add different Consumes annotations but nothing changes. Of course with FormParam annotations I'm able to retrieve single fields, but I really need the whole body of the request.

I also tried with the following

public Response testIpn(@Context HttpServletRequest req) throws IOException {  
    BufferedReader reader= req.getReader();
    String sCurrentLine;
    while ((sCurrentLine = reader.readLine()) != null) {
        System.out.println(sCurrentLine);
    }

   return Response.ok().build();
}

but I get the error

getInputStream() has already been called for this request

Answer 1

i think you can add the following code to your file:

 @Context  
 private HttpServletRequest request; 

The HttpServletRequest contains the whole body of the request!
