The node express's bodyParser can't get the parameter in the GET request

Question

I ajax an GET request in client side:

$.ajax({
        url: '/update',             
        type: 'get',    
        data: {
            "key": key,
            "value": value
        },
        success: function (data, err) {

        }
    })

then at the node side, I want get the parameter

var showParam = function (req, res) {
    if (req.body) {
        for (var key in req.body) {
            console.log(key + ": " + req.body[key]);
        }       
        res.send({status:'ok',message:'data received'});
    } else {
        console.log("nothing received");
        res.send({status:'nok',message:'no Tweet received'});
    }   
}
app.get('/update', function(req, res){
    showParam(req, res);
})

The shell show the body is empty and undefined.

But when I change the get to post (both at the client side and server side), everything is ok, I can get the parameter correctly.

What's problem with my code? Do I miss something?

Answer 1

If you are issuing a GET request, the URL parameters are not part of the body, and thus will not be parsed by the bodyParser middleware.

To access the query parameters, just reference req.query

Answer 2

You can access your data for get request in server-side by using req.query.key and req.query.value.
