如何在Express中读取jsonp数据

Question

I'm trying to send data from phonegap to an express app. Here is my code:

Phonegap:

    $.ajax({
        type: 'POST',
        url:"http://127.0.0.1:3000/test",
        data: {"test":"this works!"},
        dataType: 'jsonp',
        crossDomain: true,
        contentType: 'application/json',
        success: function(data){
            console.log('data successfully sent');
        },
        error: function(){
            console.log('there was an error');
        }
    });

Express:

    app.post('/ajax' , function (req , res){
    console.log(req.body)
    res.redirect('/test');
    });

Right now req.body is an empty object. I've included express.bodyParser() at the top of my stack, and have also tried JSON.parse(req.body) and JSON.stringify(req.body) , but neither have worked.

Can anybody think of something else to try? Do I need to do something different because it's jsonp?

Please let me know. Thanks!

The jquery:

$.getJSON(
    "http://127.0.0.1:3000/test?callback=?", 
    {"test":"this works!"},
    function(data){
        // data should be {foo: "bar"}
        // ... DO CODE
    }
);

The node:

app.get('/test' , function (req , res){
    // req.query should be {test: "this works!"}
    // ... DO CODE
    res.jsonp({foo: "bar"})
});
