Implement login_required decorator

[thomasyip]

There is no concept of decorator in nodejs. We might need to invent it, which might be complicated.

On the other hand, login_required function can be used without decorator. It can be defined in urls.py wrapping the view.

this is what I did for the view.js:

function authRequired(f) {
return function (req, res) {
if (!req.owner || !req.user) {
res.writeHead(401, {
'Cache-Control': 'no-cache',
'Content-Type': 'application/json'
});
res.write(JSON.stringify({error: 'Auth required.'}));
res.end();
return;
}
return f.apply(null, arguments);
}
}

module.exports = {
http307: {post: post, get: get, put: post},
servemedia: {get: authRequired(serveMedia)},
signrequest: {get: authRequired(signrequest), post:
authRequired(signrequest)},
postcompleted: {post: redirectedPost, get: authRequired(redirectedGet)}
};

Cool, I like it. Easy enough to port it into dingo. @ulion, thanks for the head up.
