jQuery发送JSON

Question

I need to send json data via POST, so in my var request has the structure of the json object

Anytime a button is clicked, I call this function:

function sendJSON(p_id, p_type) {
        var request=[{
          "id":null,
          "version":null,
          "type":null,
          "enabled":false,
          "priority":null,
          "params":[
            {
              "id":null,
              "version":null,
              "value":p_id,
            },
            {
              "id":null,
              "version":null,
              "value":p_type,
              "valueXML":null,
              "editable":false,
            }
          ],
          "lastEX":null
        }
        ];
        console.log(request);
        $.ajax({
            url: 'http://192.168.4.6:8080/recList/',
            type: 'POST',
            crossDomain: true,
            contentType: 'application/json',
            data: request ,
            dataType: 'json',
            success: function (response) {
                var resp = JSON.parse(response);
                alert(resp);
            },
            error: function (xhr, status) {
                alert("err");
            }
        });
    };

I can't figure it out why it doesn't work Did I forget something?
