How to use jsonp with node.js express
i'm trying to make Samsung Smart TV app with node.js .
In my project, i want to make my app communicating with server pc.
According to Many Web sites, i can do this with "jsonp".
Here is a client side code that i found.
<html>
<head>
<title>jsonp test</title>
<script src="http://code.jquery.com/jquery-1.6.2.min.js"></script>
<script type="text/javascript">
$(function(){
$('#select_link').click(function(e){
e.preventDefault();
console.log('select_link clicked');
function test(data){
return {"message":"ok"};
}
$.ajax({
dataType: 'jsonp',
data: "data=yeah",
jsonp: 'callback',
url: 'http://172.20.10.3:3000/endpoint?callback=?',
success: function(data) {
console.log('success');
console.log(JSON.stringify(data));
}
});
});
});
</script>
</head>
<body>
<div id="select_div"><a href="#" id="select_link">Test</a></div>
</body>
And, here is a server side code that i found.
app.get('/endpoint', function(req, res){
var obj = {};
obj.title = 'title';
obj.data = 'data';
console.log('params: ' + JSON.stringify(req.params));
console.log('body: ' + JSON.stringify(req.body));
console.log('query: ' + JSON.stringify(req.query));
res.header('Content-type','application/json');
res.header('Charset','utf8');
res.send(req.query.callback + '('+ JSON.stringify(obj) + ');');
});
These codes are working on my pc(server pc), but when i open client page on others computer, it doesn't work.
Console just give me this log :
X GET http://172.30.2.2:3000/endpoint?callback=jQuery11020685203080996871_1376482492523&data=yeah&_=1376482492524
I want to use jsonp to handle cross-domain, but it doesn't work i think...
What can i do to fix this?
Please give me help!!
