使用POST从php cURL接收Java Web Service中的变量？

Question

I'm recieving 'null' on my Params. So far i've found people using "PathParams", "FormParams" and "QueryParams" on java to get their variables from the request, however in my case, using post i dont have PathParams, and for some reason FormParams and QueryParams are returning null as if i had never sent them. So i'd like help to solve this.

My php cURL POST request:

<?php
$url = "http://localhost:8080/TestRest/test/asd";

$params = "param1=val1&param2=val2";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, urlencode($params));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
$result = curl_exec($ch);
curl_close($ch);

echo $result;
?>

My java Web Service:

@Path("/test")
public class Streams {

    @POST
    @Path("/asd")
    @Produces(MediaType.TEXT_PLAIN)
    @Consumes({"application/x-www-form-urlencoded"})
    public String addStream(@FormParam("param1") String param1, 
                        @FormParam("param2") String param2) {
    return "param1 = "+param1;
    }
}

For some reason param1 is null. What am i doing wrong?

I am going out on a limb and saying your problem may stem from this:

urlencode($params);

For instance: a=1&b=2&c=3 is perfectly valid.

urlencode('a=1&b=2&c=3') goes to this: a%3D1%26b%3D2%26c%3D3 and your webservice may not understand what it is your are passing. It is looking for a=...&b=...&c=... and you are not giving it any of that.

Try leaving off the urlencode() and seeing if it works. If it does, and you still want to ensure content like this&this is encoded properly, then you will need to parse the url parameters, encode them, and then recombine them for the post data.
